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

Ryan: Hey everybody. Ryan here at etrailer.com. 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 etrailer.com. 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 etrailer.com. 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.

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. 775986

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.

  • Battery Disconnect Recommendation for 5th Wheel Trailer
    The Epicord Battery Disconnect Switch # 277-000096 is my recommendation. This switch helps to ensure you preserve batteries while in storage or if just need to quickly shut off power any reason while in use. Included are both a review and installation video to provide a good overview.

  • Installation of Epicord Battery Disconnect Switch
    A battery disconnect switch such as the Epicord Battery Disconnect Switch with Key # 277-000096 will simply install inline from the 12V terminal on your 7-way to your pair of 12V batteries; because of this you are going to need one switch per battery. I have added a link to a video review of this switch for you to check out as well.

  • Hardware Needed To Install 277-000096 50 Amp Battery Disconnect Switch
    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...

  • Recommended Switch and Isolation of Two 12V Batteries
    We don't have anything to be a power selector quite like what you are describing. We have the isolation solenoid # TR118665 that will only allow power to flow in one direction so the second battery cannot drain the first which a simple switch can be added to. The other option is to have two batteries run completely separate and use the Epicord Battery Disconnect Switch with Key - 50 Amp # 277-000096 on each one. This will isolate the on/off power of each battery, but what is connected...

  • Recommended Battery Cutoff Switch for Two 12 Volt Batteries
    I cannot be for sure but it sounds as if you are referring to a battery cutoff switch. If this is the case then I recommend using the Epicord Battery Disconnect Switch with Key part # 277-000096. 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...

  • Can the Epicord Battery Disconnect Switch # 277-000096 be Installed on Negative Battery Terminal
    Since the Epicord Battery Disconnect Switch with Key # 277-000096 basically just disrupts the connection it can be used for either the positive or the negative side of the battery. Really the only time that it matters is when you install a battery disconnect like the Roadmaster # RM-766 which is designed to charge the battery while it is disconnected.

  • 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.

  • Can Key of Epicord Battery Disconnect Switch with Key # 277-000096 be Removed when On
    The only time the key of the Epicord Battery Disconnect Switch with Key # 277-000096 can be removed is when the key is in the off position. The key has to be installed for it to be in "ON". It can withstand some weather pretty easily like most wiring that you might find under the hood of an engine, but you wouldn't want to submerge it by any means.

  • Recommended Battery Disconnect Switch for Deep Cell Battery on Horse Trailer for Accessories
    Yes, the Epicord Battery Disconnect # 277-000096 would be a great switch choice for you to install on the horse trailer to ensure that all the power is on and off to your accessories with one switch to the deep cell battery.

  • Battery Disconnect Switch for a Trailer Wired for 30 Amps
    Epicord Battery Disconnect Switch with Key - 50 Amp Item # 277-000096 is rated up to 50 amps but will work with a 30 amp system. All it is doing is not allowing power to flow when turned to the OFF position.

  • Availability of Mounting Box for Epicord Battery Disconnect Switch with Key
    The Epicord Battery Disconnect Switch with Key - 50 Amp # 277-000096 doesn't have a box made directly for it that we have to offer. If you'd like something that comes with a box then we have the Marine 2-Position Battery Switch # 277-000403 which has a box that the switch is built on, but you would lose the lock option if you went this way. Attached is an installation video we shot of the Epicord on a trailer if you want to stick with that option.

  • Installation of 277-000096 Battery Disconnect Switch
    You'd want to install the disconnect on the positive leg, if you grounded the negative leg and the circuit was accidentally grounded, damage could occur. Interrupting the positive leg would prevent this from happening. We recommend installing the switch as shown in the video I've linked for you.

  • When Can Key of Epicord Battery Disconnect Switch with Key # 277-000096 be Removed
    The only time the key of the Epicord Battery Disconnect Switch with Key # 277-000096 can be removed is when the key is in the off position. The key has to be installed for it to be in "ON". And by "ON" that refers to the battery being ON.

  • 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...

    You have a couple of different options when it comes to disconnecting the power from your batteries when your Forest River Surveyor is in storage and they all just depend on your personal preference as to which one is best for you.

  • How to Turn Off Refrigerator in Trailer
    There should be a breaker dedicated solely for the refrigerator like part # 324-000119 that you can simply flip to the "off" position for when you don't want the refrigerator to draw power. If for some reason you don't have one you can install a disconnect like the Epicord # 277-000096 on the power wire to easily disconnect the power when needed.

  • Can the Automatic Battery Disconnect Be Used On a 2019 GMC Canyon Diesel
    I do have an option for you but the Roadmaster Automatic Battery Disconnect part # RM-766 will not work on any vehicle with a diesel engine no matter the number of batteries due to power surges. Instead, you can use the Deka Lead Quick-Disconnect Battery Terminal part # DW05312 or you can use the Epicord Battery Disconnect Switch with Key part # 277-000096 and mount it inside the vehicle. I have attached some other items you will need to flat-tow a 2019 GMC Canyon below. Roadmaster...

  • 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...

    It is possible to install a power switch in your truck 7-way's 12V auxiliary power circuit. This will allow you to manually control the power feed to the 7-way. Epicord offers Battery Disconnect Switch # 277-000096 that can be installed in the truck on the trailer power circuit between the 7-way and the circuit breaker.

  • Recommended Battery Disconnect System for Flat Towing GMC Canyon Diesel
    You are right that the Roadmaster Automatic Battery Disconnect # RM-766 cannot be used with diesel engine vehicles like your GMC Canyon. 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 battery disconnect like the Deka # DW05312 or the Epicord # 277-000096 that includes a switch you could mount inside the cab. This still allows...
