Guess what I've been doing??

I'd wager you're installing a backup emergency generator with an automatic transfer switch that will allow it to feed the new sub-panel and important branch circuits.
Must be a fairly large genny !!

Ding, Ding, Ding.......We have a winner

We are actually installing a 14KW natural gas, standby generator and isolating the key circuits into a sub panel. There are 16 circuits in total, we've been at it for almost 2 full days and hope to have it wrapped up by noon tomorrow. The biggest challenge was getting the wire to the Generator which is about 70' away from the panel

We should be able to run most of the things in the house if we lose power including the central air conditioning and most importantly the wine coolers..........I'm guessing we'll be kind of popular if the power goes out when it's 110 outside
