The thicker wire is actually better takes less draw to transport elec.Right now I have 6/2 with Ground (Direct Burial Wire) but I still put it in Liquid Tight before I buried it. It's not deep so I can pull it up & over to the house pretty easy. I'm just not sure if using a bigger breaker (50 Amp) & bigger wire (#6) is OK when the lighting control box for 120V says use ONLY #10 Wire & a 30 AMP Breaker. Changing the Breaker to a 30 Amp is easy if that's all I need to do. I don't see why #6 wire would make a difference; other then being safer.
What do you think ?
But breaker is vital to be right rating. If it says 30 use 30 not 50.
Wires fine breaker has to change.
