Ive been playing with my newly purchased MEP 016D. I decided to keep the lugs rather then hard wiring outlets so that I can keep the versatility of the unit. I want to run it in 250 1ph to power a transfer switch. Which lug should I be using for the neutral and ground? And for the 120 mode? FYI I dont have any continuity between the ground lug and any of the terminals. Also my understanding after reading some other posts about OSHA requirements for grounding is that the unit itself shouldnt be grounded if using another ground, ie a transfer panel hooked to the main panel ground.
