re: OT Licensed Electricians... pros and cons of backfeed cord extensions

I did it legally at my house for like $200 including a 40ft generator cord.

This is what you need:

Power inlet box
10/3 wire
Generator extension cord
Flex conduit
Rain tight fittings
A 30a two pole breaker of whatever fits your box
An interlock kit for your box


Mount the box, turn off main breaker, run the wiring and conduit, put the interlock kit on, and wire and put the breaker in. Should take a novice an afternoon.

Check YouTube if you get lost



Eta: If you wanna be a cheap arse, get some 10/4 cord (terminology is important), a L14-30P plug, and whatever 30a two pole breaker fits your box. Wire up the plug, and wire up the breaker into your box. Turn off the main, and turn on your generator breaker for power. That is illegal. If your house burns down or you kill someone, it's on you, and insurance won't help you out. You will also go to jail if you kill someone
