Wiring a Service Disconnect

I hate to put it this way, but if you need to ask, you really need to have a professional do the work. I'm sorry to be so blunt but as PBP said, your inexperience could result in a real tragedy.

First off, if time is an issue, google it. Go to the library. Or ask someone to help. Don't take a chance on this as your inexperience might be tragic. Sorry, but it had to be said.
