I will buy an interlock kit, the K-5110 . As someone else mentioned, I should install a full 240v generator connection system, but change the connection cord so there is a jumper across the legs to feed both busses when you use the 120v generator. With this kit apparently I can use both systems, 120v if I make a jumper in the cord and 240v without the cord modified.

Good thing for those who have small inverter generators like me who wans to save $$$$ in gasosline since smaller inverte gensets consume less gasoline, even more with Eco Throttle On.

 

I boughy an interlock kit made by the same manufacturer of my breaker box. Interesting that this type of devise can be use in backfeeding ( a bad word for many people here or almost all the electricians I've read. )

It includes intallation instructions, drills, corresponding nuts and screws for proper installation, etc.

Why then as soon as somoene say it is a bad thing to say " backfeeding" . ?

Also instruccions say that backfeed breaker must match the one with the genset, in my case woulb be a 30A.

This kit is to be to used with main breaker deom 70A to 125A.
For bigger gensets also come a kit slightly different with another part number.

I think every company which manufacture breaker boxes, manufcture their corresponding interlock kit.
