30A Y Connecters

There is another solution. On my previous coach with 50 amp, we often camped at 30 amp campgrounds and wanted to run our electric heater off of the additional 15/20 circuit in the shore power box, but didn't want to run an extension cord through a window.

I added a small outlet box in the power bay and ran Romex through flexible plastic conduit to a new outlet I added in the main room in an easily accessible area. I also split that off to a second outlet in the bathroom. I made a 15' power cord that plugged into the box in my power bay and into the shore power 15/20 amp circuit. This gave me a completely separate circuit from the 30 amp shore power to run my electric heater or the wife could run her blow dryer in the bathroom.

I will be adding the same thing to my new coach.

My approach was to add a second circuit with 2 inside female plugs. The other end is a male plug that plugs into the dedicated 20A engine block heater female plug. So the new circuit always has power and a full 20A when on 50A shore power. If I want additional power for a 30A pedestal then I connect this new circuit with a standard 20A extension cord for 30A+20A of power. I do keep one of the ceramic heaters on low.
