[QUOTE="Ryan Lantzy, post: 24538, member: 7"] Re: When L21-30 just isn't big enough I don't know if Lee is around, maybe he can check my math on this one.. But when all three phases are balanced, the maximum current P-P is sqrt(3) * P-N current (for conductor sizing). I.e. at 18A on each P-P circuit, you will be exceeding 30A line current. [/QUOTE]
