20amp GFCI breaker or outlet?
I need to put 3 GFCI circuits in my garage...(actually I've ran the wire/outlets etc.. and then realized I needed the gfci to pass inspection)...so I was looking the other day at one of the home centers and a 20amp gfci is $15....any chance the breaker's are cheaper?...
thanks

Don't buy a 20-amp GFCI. Buy the less costly 15-amp GFCI. It'll do the same job, and it's legal even on a 20-amp circuit.

I thought I needed a 20amp gfci outlet because it is a 20amp cirucuit...12ga wire...I will be running some of my woodworking machinery off of it....I would think that having a 15amp gfci would cause it to blow...

A GFCI does not trip because of high current. A GFCI trips because of an imbalance between the hot and neutral wires. Unless you have tools that require a 20 amp circuit (ie ones that have a 20 amp plug on the end), you are fine with a 15 amp GFCI receptacle, as long as this is the US and not Canada.
However, saving $5.00 is not a big deal, so the choice is yours.
