Can I power a multiwire branch circuit with generator?
I have a Briggs and Stratton Elite 6200 watt (8750 starting watt) generator that I plan to hook up to my main panel thru a transfer switch (probably a Reliance Controls 10 circuit 30amp) manual switch.
My first hurdle is that I have a 240volt well pump (with bladder tank), water softener brine tank, a radon water mitigation system with blower, a secondary above ground pump 115volt (with bladder tank) that draws water out of the bottom of Radon mitigation reservoir, and an oil boiler 1/7hp motor......Just to get a hot shower during power outage!! I have a watt meter that I will use to get real world numbers, but I feel I am already straining the generator with those items, but I checked my main panel, and I realized that my refrigerator is on a multiwire branch (double pull 20 amp w/shared neutral)....I wanted, at the very least, to have a hot shower, and keep the refrigerator alive during power outages.
I realize I would use a double pull 20amp (240volt) circuit to power my well pump thru the transfer switch, but is there a way to power the multiwire branch circuit to power up my refrigerator with the transfer switch as well without the shared neutral causing a huge fire hazard?
Anyone else have to power up their entire well water treatment center with their generator?
Thanks in advance for any/all advice.
