Ok, I know this is not a new question. I am having to redo some old wiring in my basement. There are several outlets in series and I thought that you can protect them if you install a single GFI at the first outlet, correct?

If so, how many regular outlets can you have downstream?

I plan on placing double outlets at each location, so there will be a total of 6 duplex recepticals and will be on a 20 amp breaker.

Could I just install a 20 amp GFI breaker and be done with it all (install all regular 20 amp outlets)
