Combiner Box Questions
Hello- I have a few questions about wiring an outback combiner box. I plan on running three #10 AWG "sunlight resistant" wires from the panels down the roof and around the fascia to a combiner box mounted under the eave. Should I place the wire in conduit to get around the edge of the roof to the box or just secure the wiring together and to the house? What type of conduit is usually used for the run from combiner box to powercenter? I assume not to use metallic. My last question deals with battery wiring and if washers are commonly used under the nuts to help hold battery cables in place? Thanks for any suggestions.
