Question: Could someone tell me why you would have to run a light in a travel trailer when you use a 110v device to keep the circuit from tripping?

Answer: We’ve never heard of having to run a light if you want to use a 110 Volt device.

Your situation as described doesn’t make sense to us. Most RV lights are 12 volt Direct Current (DC) vs 110 volt Alternating Current (AC). Typically one would have nothing to do with the other unless there is a short.

We suggest you find out where this problem originates with the help of a competent RV repair facility or electrician that can diagnose and fix the problem. Just a wild guess on our part: perhaps you have a ground problem where somehow a DC negative or positive lead is interacting with the AC ground. This could potentially be a hazardous condition. So we think you should have it checked by a qualified professional.

Other input welcome.

Wiring fault

by: Anonymous


I had the same thing in a trailer years ago. The trailer was not wired correctly. When one interior light was on, the voltage to the outlets doubled.

LIGHT TO PREVENT CIRCUIT TRIPPING

Here is an example of what happened: We were using the outside receptacle and had a small compressor plugged in and the compressor seemed to be sluggish. My son went in and turned on one of the lights and the compressor started running at full speed. It was like there wasn’t enough voltage or something.
