I plan on rewiring my garage. I plan on having three wall outlets on a gfi line and "possibly" branch to the two garage door openers from the non-gfi side of the gfi outlet. I have no special (large)current draw in the garage other than the openers. Would I be much better off running a detecated line for the openers? I have really no idea how many amps they draw on the average. It would be alot a work to do this extra line, but I want ot do it the standard practice way, whatever that would be. Thank you in advance.
