[QUOTE="metalheadjoe, post: 8854293, member: 581422"] 1) Wire resistance increases with length, which is why you see wire size charts that factor in thickness and length (insert mom joke). If you have 2/0 all the way to the reducer, your overall wire resistance is lower. 2) Goldilocks situation here. 2g is too small. 2/0 is not necessary. 1/0 is "just right". Having said that, if you can afford and route 2/0, you absolutely should. There's no such thing as too much current capacity. Your wire doesn't get hot because it is such an enormous "resistor". You have 10' of 1/2" think metal to dissipate the heat it generates. It would take a lot of energy to make it warm to the touch, but that doesn't mean you aren't losing output. I need more info about your configuration to say whether your wiring is sufficient. [/QUOTE]
