After scanning the entire forum and noticing my lights dim when powering up my system, I have decided to get a dedicated circuit breaker for my HT. A couple of question:

1. How many amps? 15? 20? An electrician I ran into at Home Depot said he would go with 30amps. I will have my entire system hooked to it I guess (755, 950, dvd, tv, vcr, sat, ps2 so far).

2. I have seen many stating they use "hospital grade circuit breakers." What does this mean? I have done many searches on google and cannot find any suppliers of these. The Home Depot people looked at me as if I were crazy when I asked for these.

3. What does GFI/GFCI really mean besides the little reset button on it? Do I need this?

4. I am not an electrician or anything remotely close. I will definitely let a professional do this. How much does this cost on average? Is this something the local electrical company typically does?

Thanks for any help.
