Installing a GFCI outlet with load side outlets.

GFCI ( Ground Fault Circuit Interrupter ) outlet and breakers are being used more now than ever. When I first started in the electrical business GFCI's had very limited use. Perhaps because they were new technology and Very Expensive. The first GFCI's were breakers, then latter GFCI outlet's which were a lot less expensive. Exterior and bath rooms were the first locations to recieve GFCI protection. Now with what has been added in the 2008 national electrical code ( NEC ) GFCI protection is required any were water may be present: Kitchen counter tops, Bath room's, Laundry rooms, unfinished basements, Garages, including the outlet provided for the garage door opener, all exterior outlets.
I often get service calls related to GFCI outlets, or outlets that are on the load side of a GFCI outlet. The first thing I will ask a caller when they are missing power in a outlet, is the location of the outlet that is missing power. If the outlet that's missing power is one that would require GFCI protection wether it's the actual GFCI or not will be my first clue to why there is no power in the outlet. GFCI's have reset buttons. When the GFCI button is located power can be restored by resetting the reset button. I have saved many customers a $75. service call by guiding them through the phone to were that reset button might be found.
