I have a 97 pace arrow 36s. This unit has a 30 A shore power hook-up and I think the wiring is not heavy enough. I don't know the long term history but it seems that the supply line has been altered. It has #10 wire that connects to the shore box and then to a junction box in the outside bin under the coach. This is a simple wire nut junction connection and goes to a #12 wire which then goes up into the coach and I cannot tell where from there but it is still the main supply line. I assume this connects into the breaker panel or more likely some kind of switch that the gen set also hooks into that switches between the 2 power sources. When I run off of shore power using the AC unit(s) and other appliances etc (big power draws), the breaker panel cabinet gets warm. When I run the same stuff off of the gen set, nothing gets warm. My thoughts are the 12 wire supply line should rather be a 10 wire for the 30 A service. I assume with several things running I am exceeding the 12 wire capacity and it is getting warm. I assume that the gen set is wired separately into the breaker panel area and done correctly so no problem. Does anyone have a general schematic of how this all should tie together before I tear into this and get too confused? Thanks!!
