Thanks, both the box and breaker are Cutler-Hammer. Its snapped in and now I'm ready to attach the wires. The power is off.
The wire from the generator has three strands......black, red and green.. Which two attach to the breaker ?

I would be more worried about the guys working to repair the service, cause it certainly sounds like White1944 is trying to backfeed his service with a gen, with out an auto switch.

Aside from the aforementioned advice that your generator lead does not have enough wires to tie-into your house wiring, you cannot simply tie a generator into a service or sub-panel via a double-breaker. First of all, a 5,000-watt generator will not be able to provide power to your entire home during a power outage. You need to select which circuits will be powered by the generator (a few lights, refrigerator/freezer, that sort of thing) and make sure the draw of those circuits does not exceed the capacity of your gen.

Second, you must use a transfer switch. This functions by isolating your selected circuits and switching the incoming power to your selected circuits between grid power and the gen. You cannot have any circuit connected to both sources simultaneously. Without the transfer switch, there is potential to backfeed electricity into the power grid and injure or kill unsuspecting workers. That could result in criminal liability if this is the result of an illegal installation.

You'll need to have this work permitted and inspected (your local code may not even permit a a homeowner to complete this work, due to the potential for backfeed to the grid). If you are coming here asking questions about how to stab a breaker into your panel, this is out of your league. Call an electrician.

Clashley x 10 Especially the last paragraph.

Asking how to mount a CB is the first clue you shouldn't be doing what you are doing.

You are not just endangering yourself by installing a generator incorrectly, you are also putting utility workers at risk. Call an electrician.

I thank all my expert electrical friends for their sage advice. You will not see my charred remains at the morgue, nor any utility workers or household members put at risk. A certified electrician is coming tomorrow and I'll pay him with my Christmas booze money. Merry Christmas all!!!!
