If you have two GFCI than one will not protect you. This would make one cancel the other one out. Look at a bathroom if one outlet is the GFCI the other is not. BAD to have on the same circut...

Absolutely wrong in every way.

GFCI's do not/can not "cancel" each other out. It's not possible for such a thing to happen.

The reason the bathroom will have onr GFCI and one regular outlet is because the regular is daisy-chained off of the GFCI and inherits protection from it. There's no need for the second one to have a GFCI circuit in it.

Just to add a little more fuel. I worked for years in an industrial environment. Our safety procedure manual called for "double ground fault circuit interrupters" or 2 GFCIs inline, anytime there was work to be performed in a "wet environment". The thought was, redundancy. While this is probably unnecessary, in 35 years, and 100ks manhours, no electrical incidents due to GFCIs (or lack thereof). - Dwain

This would be the same as canceling out a GFCI outlet too. One trips in the line all within the daisy-chain will trip or cancel each other out...

I guess I don't understand what you mean by "cancel each other out". ???

You presented it as if it was BAD to have two of them in series. And it's not bad at all. It's redundant and unnecessary, but not bad at all.

OK question, WHY? why would you not want GFCI?, sure sometimes it is unnecessary, but i don't see why you if you have the GFCI you wouldn't do it?

+1 This is a mystery to me also. The possible problem I see would be mistakenly plugging into the non-GFCI receptacle which would offer no protection at all. The floor in my brewing area is usually wet, so a GFCI is mandatory for me.

I want the gfci... I was just hoping to protect the pump with it in the circuit. Something like: source > gcfi outlet > on/off switch (control the pump) > pump. Any chance someone could work up a wiring diagram for that? I will have the gfci and the switch in a double gang box (see video previous page) the pump would be hard wired to the switch. Thanks in advance for your help!
