Hi Kevin,
I second David's suggestion to have your electrician follow the installation guidelines set forth by Vince. I had the electrician do it for the dedicated circuits I had installed in my Ashland listening room and it was well worth it.
I guess it would be nice to find an electrician that's done this task before, but I wasn't able to do that in Ashland and it worked out very well. I just found a highly recommended electrician on Yelp and they followed by instructions to a "T" with the exception of the application of the silver paste - it really only requires a very small amount and excess just gets everywhere!
Best of luck and let us know how it goes.
