1.) Is there any issue with having a GFCI breaker and the other outlets including the lamp post on the same circuit? 2.) Also, if GFCI is so much safer than traditional breakers than how come they are only used in specific places (Kitchen, Bathroom, Outside). Why not use them everywhere? I assume the answer is probably cost, but when building a home is it really that much of a cost difference when looking at the larger total?
