Hi all, here's my dumb question for the day: took apart my 110 breaker box in my '76 Shasta 1750, to check the condition of the breaker and the connection points...and found a spot for a second breaker, and what appears to be an unused line! There is shore power coming into the box, 110 going to the converter, another 110 line going out of the box but connected to the breaker, and a third line out not connected to anything in the box. So, where does this mystery line go? The current breaker is 20 amps, I am thinking of adding a second 20 amp breaker and using the "mystery" line, but I need to know just where it goes first! Anybody have any ideas?
Any licensed electrician can decipher the mystery. I do NOT recommend doing this yourself. I had a trailer come in with the breaker removed. Turned out to have a screw thru one of the wires which could have electrocuted somebody...
Also, we refrain from in depth 110 electrical discussion on this board. We can help with things pertaining to vintage trailers but do not discuss "how to" wire a trailer. Our focus is more along the lines of wiring location, protecting wiring, parts and pieces needed, that sort of thing.
Thanks for understanding. For safety's sake, contact a pro for this one.
With everything unplugged, I got out my voltmeter and decided to see if I could trace that mystery line. FOUND IT! It's a dedicated line (definitely NOT connected to anything else) going to a block-off plate on the ceiling, next to the roof vent. My guess is it would have provided power to an A/C unit if the trailer had been ordered with one. Everything inside the box looked neat and tidy, undisturbed factory work. So, someday I'll add AC and I know where the dedicated breaker goes, mystery solved! Thanks for the advice, I'm not a licensed "sparky", but I've got some experience with both A/C and DC wiring (36 years as a Tech. Ed. teacher will do that) Thanks again!
