WFCO WF-8735-P 35 Amp RV Power Converter with Battery Charger - Perfect for RV, Camper, and Travel Trailer Electrical Systems

I put this converter in today. I began around 9 a.m and finished at 5:30 p.m. I'm quite adept with tools and repairs and construction, but electricity and wiring have always been my weakness. Here is some advice.Take photos of the Circuit Breaker wiring in your old device. Take many and from all angles. Label each black wire as you undo it. ALl of the whites go to the neutral bar and the grounds go to the ground. The red, green, blue, brown, yellow, and grey wires matched the 12 volt wires perfectly ( I didn't use the green or the grey at all, but I taped off their ends with electrical tape).My mistake was that I missed labeling the main power wire which was in terrible shape and resembled a ground wire. That alone caused me to throw the breakers in the house several times. Then, I didn't label the kitchen wire because it was buried, and that took me a while to figure out as well. I had to go to the store twice. Once for wire nuts and electrical tape, and then for a new breaker. My errors destroyed a 15/20 breaker connected to the box and that took me a while to figure out. The store didn't have a perfect replacement so I went with a 20/20 breaker. That worked after I blew four 15 amp fuses and finally used a 30.IN the end, my new WFCO is working perfectly. It has to be quality equipment or I would have destroyed it three times over.Again, before you undo the old box, be precise with your records.
