Reddit mentions of Conntek 14101 15A to TT-30R RV Plug Adapter

I'm sorry if maybe I used inappropriate terminology, but I believe I did this by the book. I hired a professional electrician to replace my entire panel with a whole new one that had a transfer switch built-in. The new panel has two sides, two vertical rows of breaker switches. On the left side, the top one is the main switch to turn the power on and off from the power company. On the right side, the top similar breaker is the one which turns the generator line on and off. In between, there is a physical slider which stops both of those breakers from being on at the same time. So you have to first switch the mains off, then slide the slider over, then you can switch the generator on, and with the slider over to the left, it's physically not possible to have the power company at risk from the generator, since that breaker is off and cannot be on at the same time as the generator. As far as I know, this is as "by the book" as you can get. The whole panel is designed around being a transfer switch panel, and it was installed by a professional. This is not the same as "backfeeding", as far as I know.

The PB30 inlet is what the same electrician installed on the outside of my house. It is connected to the generator transfer switch in the new panel.

I explained what I was doing with the cord to my electrician, and he told me it made sense. When I explained "white to bright, green to ground" I was just using colloquial terms. I know how to wire up a plug, and I know how the inlet works with the ground, neutral and two hot (X and Y).

As I said, I'm not trying to run any 220V appliances with my generator. I have those breakers turned off while I am on generator power. So all I want to do is make the 120V that the generator is putting out be available to all the breakers in the panel. As far as I'm aware, there is no safety issue with this, since all I am doing is supplying power to both sides of the same panel. There is no danger to the power company, and I don't see why it would be causing any fires, since the 10 gauge line I am using is rated to 30 amps, same for the plugs, they are all overspec for what that little generator will be putting out. Even if I'm using the Companion, with the two generators hooked together, with the 30 amp outlet, even then I am operating within the spec of what has been installed.

I'm not sure if there has been some kind of misunderstanding about what I'm doing, or if all of this still somehow constitutes "backfeeding" (I thought that was the practice of simply putting power back into the house through one of the regular outlets e.g. the dryer, but that's not what I'm doing at all - like I said, it's all being done through a new panel which has a dedicated transfer switch setup integral to the design of the thing, and installed by a professional electrician).

I know that bridging the XY terminals in the L14-30 connector isn't how that was designed to be, it was designed to have four wires, but all I'm doing is feeding the same 120V to both sides of the panel. There is no other interaction between the two sides, the utility power is completely isolated via the transfer switch, so I don't see what the problem is here. I have read about people doing this very same thing, in fact they even sell a connector which does the same as what I'm doing, e.g.

I got this, along with a couple of other components to do what I needed in order to connect all of this together:

In the end, though, I decided to also try making my own custom cord, once I understood just what was happening in order to get from 3 wire to the 4 wire L14-30, it seemed like it would be a cleaner setup to just have the cord and connectors, without all the intermediary adapters.

I really think I did my homework on this, I paid a professional to install the transfer switch and give me a bona fide inlet to connect my generator to. My only task was to get the power to both sides of the panel, and I believe I did this in a way that makes sense and doesn't introduce any particular safety hazards to the situation. So I'm not sure why I'm getting flack for this, but if I'm making some huge mistake then please feel free to educate me.

Here's a couple of adapters you can use:
One from Amazon
and another from an RV Store. I've never dealt with these kind of cords before but then I've never worked on RV trailers. There's an IMPORTANT common sense thing here to keep in mind. Both of these adapters are made to plug your 30 amp cord into a 15 amp receptacle. That means that you'll never be able to get more than 15 amps from the outlet. It will be safe but if you try to use too much electricity in your RV, you'll pop the breaker that feeds the outlet you're plugging into. And that can happen over and over again when you're watching a DVD, the electric refrigerator (vs. propane) comes on and the 13 year old daughter is blow drying her hair in a hurry so she can go out with that boy she met from 3 trailers down and get away from the 'rents for a while, ermahgerd. And if its raining outside and you're flipping that breaker back on, that could be VERY dangerous.

Oh, one more thing, DO NOT USE AN EXTENSION CORD. Just park closer to the damn outlet. ;)
