I am NOT saying that a gfi is not a good idea, or that it has not saved many people from a good jolt, or much much worse. What I am saying is that one can go a long way to protecting one self using common sense and quality workmanship. For instance there should be no denying that this:




is far safer than this:




In either situation a gfi is most certainly a very good idea, and I know that I am not the first one here to talk about not using, or not use a gfi in their system.. And I do already have one of the units mentioned by the OP on order and will be using a listed relay..

I'm thinking about getting one of those 20amp GFCI's and running it to my 50amp 240 spa breaker. Is it going to screw this up because the 50amp breaker is running to a 20amp GFCI?

What "20amp GFCI" are you talking about?

I guess I am missing where the 20amp comes in. That listing is for an 80a GFCI donut.

It says it's rated at 20amp in the description? I'm not sure what the 80a means?

Used by itself the GFCI is only rated at 20a and 120v. Since most of use will be using it with a 240v system, it requires a contactor relay which when used together, it can be rated up to 80a depending on the relay used. I personally ordered a 30a contactor relay since that is what everything else is rated at for my system

All this electrical stuff is greek to me What the heck is a relay that up's the amperage the GFCI can handle? Can you tell me what exactly I need to add to the end of the wire (outlet, relay, etc) to get an idea of how to make this thing work?

I guess I have to learn sometime, might as well be now! Thanks for the help so far!

Ok.. so having written that, I don't think this "20A" rating that is mentioned in the listing is accurate at all.

I am looking at the freaking manufacturer's documentation and it says that the GFCI load terminals on the module itself are rated for "0.6A max".

so... f#ck that seller's description. I don't yet see anything in the manufacturer's document that indicates that it can handle 20A.
