I have a 12 module AC string wired in parrallel. The 12 modules are wired to a junction box on the roof, and are wired in conduit off the roof. What is the correct practice for connecting each module to the common conductor that goes to the junction box. I would assume that it should be rated for the current of all 12 modules. Should there be a junction box at each module ? are the module wires spliced to the connecting conductors ? Should there be conduit from the module connector to the junction box ?
