I have two questions: 1) one of the planned usages for this product is to power my workshop in the case of a power outage. My plan is to use a transfer switch, connected to the unit with a pigtail from the transfer switch with a plug on the end. Would the generator require rewiring to do this? I’ve done some reading about neutral wire issues with other generators. 2) is it possible to order the unit, say today, and have it delivered on 28 January? Thanks, I do a good deal of welding and always have favored Hobart equipment.
