Also, do I use 12 gauge cable and a 20 amp switch or do I have to have a special GFCI circuit breaker in the box?
I try not to badmouth the employees there, but I never ask them questions. The only questions I will ask them is "where is... fill in the blank... located".
There are no formal education or training requirementsin the electrical field per se... only the training home depot gives them.
Depending on what these gfi's are for, you will use either 14AWG 15AMP , or 20AMP 12AWG. If it is kitchen or bath, then 12AWG wire with a 20 AMP breaker.
Even if it is a 20AMP circuit, you are allowed to use a 15AMP GFI receptacle and a 15 AMP switch, you just won't have the ability to plug in anything that actually requires above 15AMPS.
If you want downstream receps or lights to also be GFI protected, you hook the cable going to them from the LOAD side on the back, if not then to the LINE side.
