Wiring Multiple GFCI Outlets

When you need to wire multiple GFCI outlets such as in a kitchen or bathroom you have a couple of options.  To save money, you can put in a single GFCI and then wire additional standard outlets to the "LOAD" output from the single GFCI.  This provides the same protection as having a GFCI at each location.  The downside is in going this route if the one GFCI trips, all of your outlets lose power which can be a nuisance.  When multiple appliances are running from a single GFCI it is also more likely to trip. 

I prefer the second option shown below which is to put a GFCI outlet at each location.

NOTE:
If you miswire a GFCI it may not prevent personal injury or death due to a ground fault (electrical shock).

If you mistakenly connect the LINE wires to the LOAD terminals, the GFCI will still operate like an ordinary outlet, but will not interrupt a ground fault.
