ECN Forum Forums Code Related Discussion NEC & other Code issues lights within a shower stall

I have seen a lot of bathrooms that have the lights on the load side of the GFCI. I think it is a good idea. My questions for everyone are:
1. Does the NEC specify any particualr type of load that cannot be GFCI protected? (In residences.)
2. When in doubt isn't it safer to protect circuits with GFCIs?
3. What circuts, if any, do you protect with GFCIs in addition to those that are required to be?
Thanks in advance for comments.
