In most locales, when it comes to electrical work, homeowners can do whatever they please IN THEIR OWN HOMES as long as the work is code compliant. There are a few areas that restrict homeowners from doing theor own work. Some even require homeowner-work to be done under the supervision of a licensed electrician. Calling your local code official is much less epensive than ruining your house.
That said, realize that homeowner-induced electrical fires are all to common, as well as homeowners zapping themselves or a loved one due to poor procedures.
Don't mess with the meter.
One added item...many homeowners try to "sneak" the work in without getting it inspected by their code officer. Why? Are they ashamed of their work? Do they think it will fail inspection? They don't want to pay a nominal fee (if even required)?
If they are, they shouldn't be doing the work in the first place. Be proud of your work, show the officer. One of two things are going to happen. He's going to say "nice job" and walk off, or he's going to say "this is unsafe" and allow you to fix your errors.
You should only be satisfied fromm working on your own house by knowing you've done a good job.
