Video Transcript for Epicord Battery Disconnect Switch with Key Review and Installation

Ryan: Hey everybody. Ryan here at Today on our travel trailer, we're going to be taking a look at and showing you how to install the epicord battery disconnect switch with key. This battery disconnect switch is going to be a very quick and easy way to disconnect the battery power from your travel trailer, which in turn is going to help prevent your battery from going dead as well as prolong the life of it. This could be very easy to operate. Just simply pull back your protective dust cover and put in your tethered key, and you can rotate it to turn it on and off.

Now once it is in the on position, you'll know it's on because the key cannot be removed. However, whenever you turn it off, the key comes right out and you can put that cover back on. And I'll give you a quick example of how it's going to work. As you can see now, the key is not in it, that means it's in the off position. And with our electric jack up front, we hit our switch, it's not going to operate at all.

Now I'll go ahead and put our switch in the on position.With the switch on, we now have power to our travel trailer. This also makes it very convenient if you have to make any electrical repairs or even updates. When doing that job simply just turn your power off, get the job done, and turn it right back on. And when taking your trailer out of storage, you're not going to have to worry about bringing a jump box with you or bothering someone to help you out with some jumper cables. Now one of our customers did write in and say he actually had the key brake.

Now the key is made out of a pretty thick plastic and it doesn't take a whole lot of effort to actually turn the switch, so just be conscious of that, especially in that cold and brutal weather.Now the switch is rated for up to 50 amps, so anything at that or below is going to work good for you. Now one of my favorite things about this switch is that it can be mounted flush and give you that nice clean look. Now, although this can work with two batteries, keep in mind that either they're both going to be on or both going to be off. If you're looking to control your batteries individually, I'd recommend a dual battery isolator switch, that way you can either disconnect both, connect both of them, or like I said, turn one on and one off. On the back of our switch, our posts are going to have a diameter of three eighths of an inch, and it's also going to come with the necessary hardware you're going to need to secure your cables to those posts.To begin our installation, we're going to locate our battery and disconnect all of our power cables.

With everything disconnected, now we need to locate a spot to mount our switch. Now you don't have to do it this exact way, but this is the way that I'm going to do it today. I'm going to mount this right here on our header and I'm going to drill a hole and mount it right here. And I like to do this first that way we know where to run our wiring. If you do drill into anything, just make sure that there's nothing of importance behind it that way we don't damage anything. I'm gonna use the hole saw to make that hole.Now to help prevent any rust or corrosion on this bare metal, I'm just going to shoot a layer of spray paint over it. Then what I'm going to do is take our positive cables that went to the positive terminal on our battery and feed them back up through here and get them to come out of the hole that we drilled. Now we can hook our cables up to our switch, but before we do that we want to ensure that the switch is in the off position. So to make sure it is, as long as you can pull the key out we know it is in that off position. So I went ahead and removed the hardware on our post, and we're gonna put these cables on our top post. Put on our split lock washer and our nut. Now we're just going to run these down hand tight for now and we'll tighten them here in a moment.Now we can connect our other cord to the back of our switch here at the bottom and run it over to the positive post on our battery. Now I do want to point out that this switch does not come with this extra cable, but if you need one you can find it here at What we'll do is take off our hardware, run the end of our cable through our hole. And once again, we're just going to loosely install it for now. So now we can kind of position our cables in a way that makes sense to ensure that they're not gonna come close to each other. So I'm going to use this setup right here. And once we verified that we can then snug down our two nuts. And since our new battery cable had quite a bit of exposed metal, I went ahead and just wrapped it up in some electrical tape just to help keep it protected.Then what I did, I pushed everything through and held this in place where I want to mount it, and I made a few marks. What I'm gonna do is pre drill small pilot holes in here that way it'll be easier to run my self tapping tech screws through here to secure our switch to the trailer. If you need some of these tech screws you can pick some up here at And finally we can take our new battery cable that's running out of the back of the switch and connect it to that positive terminal here on our battery. Now we can test it to make sure everything's working properly. So as you can see now, with the key out and in this position, our battery disconnect is in the off position. And just for a quick reference, we're going to test our jack to see if it is working with our switch.Now this is hooked up to all the same things that are inside of our camper. So if this doesn't work, nothing else will work inside. So we can try and go up and down and nothing is happening. Now let's go ahead and turn our switch on. Make sure we get power. Now we'll see if we have power. So it looks like everything is working properly. And that'll do it for our look at and our installation of the epicord battery disconnect switch on our travel trailer.

Epicord Battery Disconnect Switch with Key - 50 Amp - 277-000096

Average Customer Rating:  4.7 out of 5 stars   (82 Customer Reviews)


Item was delivered before the expected delivery date. Fast service, good communication. I will use etrailer in the future.


Well pleased with product , installed on our travel trailer to disconnect while not in use.

Paul G


No problems with this disconnect helps maintain battery charge while camper not in use also good safety feature for killing 12 volt power to camper.


Good quality and a good price. Purchased these for my travel trailers. A must have to extend the life of the battery. Posted pictures of how I installed it to the battery box.


Excellent quality. Versatile mounting options for a travel trailer. I mounted kind directly to the battery box. No issues.


Seems like a good cutoff so far


I just installed this as a replacement for an identical switch on my 2018 2109S Rockwood camper. The original switch failed. This one seems to be high quality so hopefully it will last. Because it was an identical switch, I was able to take the switch out of the backer plate and install it on the backer plate for the old switch. This was easier than taking the mounting screws out of the camper frame and worked perfectly. etrailer was the only place I could find an identical replacement. As always, etrailer shipped quickly and I am pleased with their service.



Ive had this for a year now, and it is still working great. I wish it were designed so the holder for the socket cover did not slip off so easily, but that is a very minor annoyance.


Great customer service!


Always have what I need, fast and easy


This battery disconnect was easy to install. Overall quality and functionality has been excellent. I will purchase this item again when necessary.


I was really amazed when I received an email asking if I would like an alternative part since the one I ordered would take awhile to get. Definitely will order from etrailer in the future


Exact swap for the original that wore out from 2018. Simple install, works, good to go. Thanks!

Easy installation


Purchased to install a battery isolation switch in our travel trailer. Installed it into a square junction box to seal off and weatherproof the wiring connections Works like a champ.

Mike L.


Works great. Completely shuts off power to the fifth wheel and helps keep the battery from suffering from vampire drain.


The 50 amp Epicord Battery Disconnect Switch with Key that I purchased from etrailer arrived in a timely manner and was a very good quality. It worked perfect for my application. I highly recommend this switch and etrailer.


Very simple to wire. To avoid unnecessary drilling into the trailer, I simply went to Walmart and purchased an oversized battery box. It easily fit in the same location on the tongue. I cut a hole in the end of the box and mounted it there. No exposed wires or connectors.


Ordered the part and received it a day earlier than expected.
The part is better than the original because it comes with the protective cap that can be used when the T handle key is not in place.
Ordering from etrailer is the best, better than the big e-commerce place, because they follow the product all the way to your door and even ask if it worked for you.
Very pleased!


Purchased this switch to be the master battery shutoff for my camper. It is mounted outside and to the frame of the camper. After one year of use it is still working well. It was easy to mount and connect the battery cables. Appears to be a sturdy, well built part and I would recommend this product to others.


I ordered this to replace an existing defective disconnect switch on our travel trailer. I am by no means mechanically inclined, but after watching the video, the install was straight forward & easy. The most difficult part was removing the rusted screws from our original one. This switch fit right in where the old one was mounted on the frame and has a sturdier key than the one we have had. It's mentioned in the video, but note that the mounting screws are not provided in the disconnect kit. You must supply your own.


I've purchased two of these switches now over the last 2 years because they fail after 1 season. Definitely need a better solution for a disconnect

Etrailer Expert

Jenny N.


I will have our Customer Service team reach out to you. The switch does have a one year warranty.


Great replacement for the broken one.


This worked great. You had to be a tad creative and know your electrical supplies to buy the right plastic box and fittings to install it. And don’t forget to maintain proper polarity when you hook things back up. I have no idea why I would say that.


This was the second disconnect I purchased in a year. The key broke off inside the first. So far this one has been fine.



The replacement has worked perfectly


The switch failed after a couple days. It caused major difficulties for my camper and camping experience - a long story. It's a switch! What can go wrong? The company sent a replacement fairly promptly, but the damage had already been done. I hope the replacement works.


We received it fast and it was exactly what we needed as our replacement part


This battery disconnect is perfect of isolating my RV batteries. I mounted it on a plastic 4x4 junction box and then onto one of the battery boxes then wired it up. Works great!.
Easy to install and easy to use. Saves unwanted battery drain when the RV is not in use.

  • Can the Go Power 200 Watt Solar Flex Charging System Charge Lithium-Ion and Gel Batteries Together
    The Go Power Solar Flex Charging System part # 34272628 can charge two different battery banks separately. Therefore, you can charge both the lithium-ion and gel battery banks at different rates. There would be one profile for the lithium-ion battery/bank and another profile for the gel battery/bank which would charge them at different rates so it is adjustable in that sense. In regards to killing power to either bank, the device will do this for you once the battery/bank is fully charged...

  • Will Installing A Cutoff Switch Damage The Redarc BCDC1250 Battery Charger
    I spoke with Redarc and installing a cutoff switch like the # 277-000096 between the Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC - 12V/24V - 50 Amp # 331-BCDC1250D and the auxiliary battery will not damage the unit at all. You will get a low voltage output battery fault, but since you know the cause is the cutoff you can just ignore it.

    The 50 amp battery disconnect switch would install inline on the positive battery cable. If there's enough slack in the positive cable to reach the area where you want to mount the switch, you'd simply cut disconnect the positive battery cable and cut it at the point where it reaches the terminals on the back of the switch. You'd need to install a ring terminal on the wire, but the size terminal you need will depend on the gauge of the wire used for the cable (the wire gauge should be printed...

  • Preventing Battery Drain In Storage On A 2018 Momentum RV
    If your trailer is off or in storage and the battery is draining then you should install a battery disconnect switch like the Epicord Battery Disconnect Switch with Key - 50 Amp # 277-000096 to cut all power consumption from your batteries. As for charging the batteries the Go Power Eco Solar Charging System with Digital Solar Controller - 80 Watt Solar Panel # 34272627 will charge approximately 27.42ah a day in peak conditions so if you're having a larger pull than that in a day you'll...

  • Battery Disconnect Switch for Use on Travel Trailer
    You can use the Marine Battery Switch # 277-000403 for your application but since this item is not rated for outdoor use I recommend using a junction box like # 3375601100 to provide a degree of protection from moisture. The switch housing (not including the knob) is about 1-1/4-inches deep so you'd want to use hardware that is about 2-inches long. If space is available in your battery box you might be able to mount the switch there. In this case a better choice might be the Epicord Battery...

  • Could Epicord Battery Disconnect Switch Be Used on Trailer with Dual Batteries
    Yes you could use the Epicord Battery Disconnect Switch # 277-000096 on a travel trailer that has a dual battery setup. Your batteries are most likely wired in parallel and use one of the terminals of each battery as a power and ground for the rest of the trailer's wiring. You'd just need to install this on one of those wires and you'd be set. I attached an install video for this for you to check out as well.

  • Question on Progressive Dynamics 5100 Series Transfer Switch
    The Progressive Dynamics 5100 Series Transfer Switch, # PD5110010Q that you linked to will automatically reroute your RV's AC input from shore power to generator power when activated. While many manufacturers will source parts from the same supplier, the case that each unit is mounted in may be similar, but this is not the same item as available from Go Power simply relabeled.

  • How to Disconnect the Battery on a 2021 GMC Sierra with Diesel Engine
    You are correct that the Roadmaster Automatic Battery Disconnect # RM-766 cannot be used with diesel engine vehicles like your GMC Sierra. The issue is the high compression ratio of diesels that cause the engine to surge up to 10 times that of gas engines, which can lead to failure on the solenoid. What you can use instead is an alternate-style of battery disconnect like the Deka # DW05312 (uses a knob to attach and detach) or the Epicord # 277-000096. The Epicord # 277-000096 includes...

This switch has easy to use bolt-on terminals, comes with a removable key, and has a 1-year warranty. You will need one switch for each battery. In order to install the switch, I recommend making a circular hole for the terminals to slide into and then attaching it to the outside of your plastic...

  • Will the Battery Isolation Solenoid Use Fuse or Circuit Breaker In-Line?
    The Battery Isolation Solenoid # PK5231201 will keep the trailer battery from continuing to draw power from the vehicle battery when connected. The power is only transferred when 12V power is active on the center post with the 12v sticker. You can use any power source like the running light circuit to allow power to flow. I recommend using a circuit breaker like # PK54540 on that wire. Another option is to use a disconnect like the Epicord Battery Disconnect Switch with Key - 50 Amp...

    Thanks for reaching out, Rob! Have you been using your ArkPak 715 Portable Power Station w/ 150 Watt Inverter # AP715US like this for a while? Usually when something starts acting weird it's because something in the equation has changed. If your ArkPak is consistently plugged into the cigarette socket then that would be a contributing factor as to why your battery is being drained, and it would be beneficial to disconnect this when your vehicle isn't running.

  • Can Power Tool Battery Pack be Used to Power Utility Trailer Lights
    To run lights in your trailer you need to use a 12V battery so you'll likely need to get an additional battery since power tools generally run off of 18V. To keep the onboard 12V battery power separate from the 12V power coming from your tow vehicle I recommend adding the Epicord Battery Disconnect Switch with Key # 277-000096 - this way you can turn it off and disconnect the battery when you plan on being plugged into your truck, but you also have the availability to switch the key on...

  • Does Epicord Battery Disconnect Switch with Key # 277-000096 Need Wiring Diagram
    The poles of the Epicord Battery Disconnect Switch with Key # 277-000096 that you referenced are not polarity sensitive so you can run either pole for either wire. Basically this just acts as a way to either open or close a circuit so as long as you attach both wires to it the polarity would not matter.
