There is not going to be much difference between wiring this plug and the plugs in the previous section. The key is to make sure you put the 2 hot wires on the right prongs and the neutral and ground on the other two prongs.

Wiring is very straight forward and once you get the hang o fit, it does not take long to get the job done. The key is to always turn that power off before you do any wiring or connection work.

With a 50-amp system, you will always need 2- 120 volt hot wires. It is the 30-amp and lower systems that only need 1-120 volt hot wire. It is easy to get them confused at times but 50-amps is 240 volts and 30-amps is 120 volts and that should help you keep everything straight.

If you have any doubts, just ask an old pro. They will make sure you get the wires set up right without making the same mistakes when they were new to the electrical field.

You can find more diagrams and images at this link- https://faceitsalon.com/50-amp-rv-wiring-diagram/ although the English on that website leaves something to be desired. The images and diagrams are what you will need the most from that location.

Then, here are a few tips to help you when you take this project on:

1. Make sure the connections are tight- it is easy to think they are tight and they may feel tight. However, they may not be and you should double-check to make sure. Loose connections can cause some havoc when you need to use that 50-amp outlet.

2. Power test- once you have made those connections, take your multimeter and test for power. If the system is not registering or it is registering very low, then you made a mistake somewhere and need to retrace your steps to find the problem.

3. Follow the code- The National Electrical Code lays out everything you need to do to have a very safe wiring system. Get a copy of the code or just the part that deals directly with your project and follow it.

If you can’t get a copy, ask a professional electrician or call your local city hall for the office that inspects new construction to get the right information. This is for your own protection and protection against risks that arise with badly wired electrical components.

The key to doing any wiring safely is to know your limits. If you do not like working with electricity if you have no experience in this type of work or if you just prefer someone else to do it, hire a professional.

There is no sense in taking on this project if you are not going to be confident enough to handle the work. It is better to hire someone who knows what they are doing so you get the job done right the first time.

If you try to do it and mess things up, hiring a professional will cost you more. They have to undo all the work you did, then re-do the work so that it is correct. That takes extra time.

That extra time will cost you more in the long run than hiring a professional to do it initially.

Some Final Words

Working with electricity is not for everyone. While the above schematics help, not everyone can follow these diagrams. If you can’t follow them or understand what they are telling you to do, hire a professional to help you.

It is the best way to get the job done right. Don’t take any chances with electricity as it is possible for a bad connection to start a fire and destroy your home and RV. Play it safe at all times so you, your family, and your homes are protected.
