240v 30 Amp GFCI Solution

Postby Johnnywhiskey » Sun Mar 19, 2017 8:23 pm

What is the best solution (cost effective) to put a GFCI into a 4-wire system (hot-hot-neutral-ground)?

I'm working out the logistics to going electric with my boiler (and beer brewing setup also) and would like to make sure there is a GFCI somewhere in the system. I'll be using a 4-prong dryer outlet that I'm currently not using, but want to add GFCI protection. I cannot seem to find a cost effective solution short of having an electrician replace the breaker with a GFCI breaker. Are there any inexpensive inline 240v GFCI solutions? There are tons of 120v GFCI inline breakers, but it seems like nothing for 240v.

Absent a better solution, do I replace the panel breaker with a GFCI breaker, or maybe put a GFCI breaker in my controller box?

I use a spa panel that my buddy gave me when they cut up their hot tub.. Works great.

Just replace the breaker with a gfci breaker yourself. They literally pop in and out. Wait for a bright sunny day, kill the main supply breaker, and then remove the breaker panel bezel. Unscrew the conductors for your outlet, pop out the old breaker, and snap in the new. Then just go in reverse hooking stuff back up.

Running a still is 10 times more complicated than changing a breaker.

Heads up though, most gfci two pole breakers are $70-$120... I really should install one on mine.

Thanks guys. You confirmed what I was thinking. The GFCI breakers aren't cheap, but I'll have one installed. Probably use a electrician I know that is pretty affordable. If I'm going to install a safety device, I might as well make sure it is done right. Although the process looks pretty simple.

I thought about the spa panel solution, but I didn't want an extra box to deal with. Did you install your equipment in the spa panel or separately?
