Video Transcript for Epicord RV Wiring - Power Inlet - 277-000140 Review

Today we're going to be taking a look at the Epicord 50 amp twist lock power inlet. This inlet allows you to create a new inlet location or replace an old one. It's going to come with the installation instructions. Those are going to help with the installation process. The construction of the unit is a strong and durable construction that uses corrosion resistant materials. It's like a plastic construction.

The color is going to be black, so this is a black face plate. This is what's going to visible on the outside of your RV. It's going to offer a clean, stylish look. When it comes to the amperage, it's going to have a max amperage of 50 amps that's capable of up to 250 volts so it's going to work well for you 110 or 220 application. It is CETL and ETL US listed.

It does come with a rear safety enclosure. That's this piece right here and it's going to come with a hardware to get that installed. That secures by placing the hardware in these two internal holes, so you can see one right there and then you can see the other one right there. That threads in and this is going to be that enclosure at the back. You can also see that we have the connection points for our wires, 4-wire design and it's got the terminal screws on there so you can get the wired seated in there correctly and securely. Here on the backside, it's going to have a foam gasket.

That's going to sit between the inlet and the mounting surface to protect the mounting surface and add some cushion between the two mounting surfaces. Now to get this installed in a new location, it is going to require a 2-1/2 inch diameter hole to be cut. The lid is a nice design. It opens up. That's fully open.

Right here, it's also got a foam padding so it's going to help keep the elements out from the connection points when nothing's connected. You'll also notice that it has the threaded portion there so on those twist lock adapters, they plug in. You twist the connector and then you thread down the collar for a nice, tight, secure fit. Nice design and then once you're ready to close it up, you can see that when you just set it down it doesn't close all the way. You've got to push it and allow it to snap. That's going to keep it closed during travel. This does require the use of 6-gauge wiring. Your installation hardware's not included. In the instructions, it's recommended that you use number 8 pan head stainless steel screws. Once you have this in place, you'll notice also that it has the four mount holes, so one on each corner. Once you have this installed, you would need to take this off and take this off as well, a couple of pieces right here. So, you'd run your wiring that's connected to the RV through this component, through this component, bring it all the way to this part right here. You'd strip your wiring and then you'd place the bare wire into the color coded terminals right here. Once you have the bare wire in there, you can use a flat head screwdriver to tighten the terminal screws and it's going to seat them. That's going to make for a good connection. Once you have that done, you're really ready to go ahead and tighten everything down. This comes up over the wires, pushes on just like that. As you tighten this piece on, it's going to close this portion, which is going to form a nice tight fit over the wires and the jacketing that's around the wires. That's going to keep the elements, or anything, dirt and grime and debris from getting into those connection points. A few measurements I want to go over with you real quick. Here at the front, outer edge to outer edge going this direction, we're looking at a measurement of about 3-5/16 of an inch. Going this direction, we're looking at about 3-3/4 of an inch. Those mount holes, those are going to be separated on center by 2-7/16 of an inch and it's going to be same measurement going the other direction as well. That's going to do it for today's look at the Epicord 50-amp twist lock power inlet.

Epicord 50 Amp Twist Lock Power Inlet - Black - 277-000140

Average Customer Rating:  4.8 out of 5 stars   (41 Customer Reviews)


Installed a year ago. Recommended hole diameter is a big larger than necessary due to a protruding ridge. If I were to install it again I would use smaller hole saw an file a notch for protrusion. The larger hole lead to one of my securement screws to be very close to edge of hole and I had to use a bolt with large washer instead.


Excellent product was just what we needed to fix our doghouse. Now the crew is able to warm up left overs in the microwave and change out with some lights on. Installation was a breeze with the detailed instructions.



Still rocking in the Bakken. Product is holding up to the harsh elements out here. So we move every 3 days so thatvis alot of plugging and unplugging.


I manufacturer tiny homes and install these. I haven't had a call back in these. They are fairly straight forward to install.


Exactly what we ordered


Epicord 50 Amp Twist Lock Power Inlet - Black
Bought this to replace original inlet that broke mounting flange. Original unit was mounted with only 2 of 4 screws due to sloppy work by builder (THOR). Screw hole pattern was drilled off center. Kids stepped on power cord and that broke the flange.
This inlet was a perfect replacement for the original. Not enough material to mount using all 4 screws , so went with the original 2 screw deal.
Ordering was trouble free and delivery was quick. I have used E-Trailer before and have never had an issue. My go - to source for all of my RV needs.



The inlet is working flawless from day 1 . I have gotten smart about the cord and place it so it cant pull on the inlet. The outlet plug on the cord is a little snug to install and lock on, but that is probably due to some minor tolerance differences between the 2 different brands of components. But I would still rate it an A+ product. I am so glad that I found you and etrailer so many years ago. Your follow-ups show me that you really care about your customers. Best wishes to you, your family and all of the people who make etrailer the best company ever.


Product was exactly what was shown in photo made really good quality highly recommended


Super easy to install it’s been a year and still no issue with it. Great purchase!


You make excellent products.


Looks to be a great product. Only issue is that it didn't come with mounting screws.



Still working great.


Its a receptacle, but hard to evaluate it autonomously. I bought a cord for it to play with and reviewed as a unit, tandem units. See my other review (for 277-000151), if you please.


This was an easy install for converting a shipping container based mobile shop for use in rv parks. Taking apart for installation was a little tedious but simple design made the entire project easier to complete. Contact point have some wear from use but overall appears to be a quality product.


After a year of camping the Epicord power inlet that I purchased from Etrader is still working well. I think it is a good product at a reasonable price. It is as good as the factory original.


Product seems to be well made. Installation was easy with wires well marked. Have not used for any extended period of time yet.


Everything was shipped on time with all items in box. ETrailer made sure everuthing was satisfactory from the order process all the way to receiving it.
Thank you guys!


The item is as shown and advertized. I'm sure it will work for my needed use. Etrailer was able to expidite my order change. Very happy with their help and response.


Fit was perfect.the manufacturers one shorted to ground and melted the plastic.


The product looks good , I wish it would have come with four tesla taping 1 inch screws . Small point but still worth the review .



Great I use it every track event . Flaw less


Great company to buy your parts for whatever your project is. Also great customer service if you have a problem.


well made installed but not been able to use yet work still in process.



working fine wish I would have gotten the 90 degree plug


Item was exactly as described. Easy to install and worked perfectly for my application.


Great product and will work great on my new toy hauler I'm building


Fantastic delivery and product is right on!!


Works great, exactly what I needed. Easy order process and quick delivery.


This product replaced my original part perfectly. It was shipped in a very timely manner. Will gladly order from them again. PayPal was a big plus.
