Using camper generator to power items in house

We lose electricity sometimes. We have a 7.5kw. Since it only puts out 2 lines of 30amp 110, we opted to put 1 line through the garage wall and from the garage through to the back hall.

This is the male socket we used in the outside, to avoid a deadman's cord. Ran it to a standard socket on the inside wall. Used a single to a standard socket from garage to back hall. This allowed us to keep doors closed.

We have gas heat, gas water heater and a gas range. This allowed me to use one receptacle, coming into the garage, for the furnace and the other to plug into the line to the house. This way we had heat through the whole house and used lamps to light the house, run fridge and freezer. We intentionally use the same connection for the fridge and freezer, swapping, so we do not overload a single line into the house.

Just did it yesterday when a thunderstorm took out power for about an hour. Simply ran a 12/3 extension cord (100') with a 3-way tap from Toyhauler into the kitchen for the fridge and freezer. Ran another cord from that tap to the modem, router, and 'puters, and had internet (storm didn't take out the local cable service).

I have done this to power my house fridge and freazer. Make sure to use heavy gauge cord.

if you have a square D service panel they market a lock out switch to enable you to power up the whole service.

I have to flip the circuit breakers off on the 220 stuff cus I have a puny genny.

Need to run an extension cord direct from generator to the appliance.
Run the generator a safe distance from the house to avoid CO intrusion.
Every home should have a CO detector.

If you expect to power the electric system in the house you need an electrician to install a transfer switch.
