Found these on ebay. About half the cost of others I have found. To use them with 240v you would wire them in line controlling the coil of the relay. When the GFCI trips it cuts power to the coil and to the panel or heater element depending on which relay it is wired to. $20 shipped. I bought one for the panel I am doing right now. I like that the GFCI will be integrated into the panel itself.

The literature states that it shuts off quickly enough that a "normal healthy adult" will not experience serious electrical injury. You'll probably see stars, and you may need clean underwear afterwards, but at least you won't be black and crispy like Wylie Coyote on the Roadrunner cartoons.

Just wire them so nothing smokes and you'll be fine... so long as nobody touches anything. I mean, it's not like you're gonna have them inspected, so what could possibly go wrong?
I think you will need it so I wish you - Good luck!

/\ +1. Where is the disclaimer stating the guy has no idea what he is talking about and you're completely on your own? I'm almost tempted to buy one to see what the heck they are selling that is rated for 80 amps.

Yeah, I had a good chuckle when I read the seller's description too. "Just wire them so nothing smokes" is my favorite.

However, based on the actual instruction manual, it looks like they actually should work, provided you use one of the few contactors specifically mentioned in the manual. The problem is none of those contactors I googled could be had for less then $100. For that reason, it seems it would be cheaper overall to use a proper GFCI breaker and generic contactors.

I'm planning to build my own control panel soon, so I'd be happy to be proven wrong...

I'd suggest that you get a spa panel from homedepot.com. It's about $50. Wiring it up? Really easy.

Tell me what you have as a power source and I'll show you how.

I Wish that were the case here in Canada... The cheapest Home Depot has them for here is just about $250

I work for a spa retailer, and I can't even get one for $50 at cost... So this looks like an awesome alternative!

While the seller and his write-up may be a little corny, Leviton itself is a reputable company and if you look at the pictures of the instructions they provide a diagram of how to wire it to a relay. Any relay with a 120v coil should work with the GFCI. If this doesn't work and I don't see why it wouldn't I will end up going with the spa panel recommended from Homedepot

In my mind the issue is more how fast it will work. GFCI's have to operate in as little as 25 milliseconds. This includes the time to drop out the relay. The manufacturer certifies that certain relays meet this criteria, but yours may or may not. I wouldn't be comfortable using a non-certified relay without testing it.

25 milliseconds or 25 seconds, what's the difference, it's just a little electicity!
