However depending on the load of your house you may be able to get away with one head, especially with a open floor plan.4) You need to talk to a installer/supplier to see how many BTUs it would require to adequately supply your home and see what your options are.

It's two poles separate the incoming 220VAC into two 110VAC "rails" that the smaller house breakers plug into, and then the house wiring attaches to those to distribute power to the house.If you disconnect the main you separate the street from the house wiring, and because all the 110 VAC and 220 VAC breakers connect to the "rails", once you supply power through the dryer outlet (220VAC) you are connecting the generator to all the house wiring via both "rails".Hope that helps...

I used to be in auto-upholstery, and my main business is now selling retail sewing supplies online@Scott Trench - To your first and your last point, this is very understandable.

Another project I pay for and do myself.Not to mention that when contractors show up, they want all the supplies right there.  

What appliances do you supply.

Vacasa also just raised $35 million to expand.With hotels getting a stronger foothold in the industry, things will certainly be changing soon. 

I finished the year strong, but the lack of supply has been EXTREMELY frustrating to me and my clients.

Thanks for reading and supplying feedback if you do.
