I am installing a combination fan, light, night light shower fan in a new shower, all of which are on separate switches. The electrician pulled all three switches to the panel box. It sounds to me that I will need to install 3 GFI breakers. Will I need to have all 3 on separate GFI breakers? What is the code for this situation?

The fan,light, and night light does not need separate circuits, all can be on one GFI.This can be protected by the GFI receptacle that may be in the bathroom, or by one GFI breaker.

Why did he feed each switch with separate feeds?
