I went back and forth on the EPO method and opted for the GFCI trip. I looked into proper shunt trip beakers but they're damn costly so opted against. Tripping the GFCI is the next best thing in my opinion. Having the coil power run through the NC block on the EPO is a nice backup plan if for some reason the GFCI doesn't trip, but I think it should be the backup and not your primary option.

Agreed. The way I'm looking at it is this: Unless, I'm an idiot and have blown the fuse on my GFCI shunt, and my GFCI has not failed I kill all power to my panel. Unless something has seriously gone wrong with my contactor (or my e-stop switch) I've killed all power past my main relay. If both those have failed simultaneously, I should just expect the incoming meteor impact as I win the lottery.

An OH - By the way - The 1 amp fuse I placed in the diagrams is only there to insure that the wiring is done in a proper way. Once completed and tested, it is no longer needed. (It is a initial don't fail on me plan - once done? Not needed.!)

Sorry but I must disagree. Unless your control panel falls into your boil kettle, what is the reason for killing the feed? If it did fall into the BK, the gfci would take care of that anyway. Killing the main contactor will kill all power leaving the CP and that is where the issue would be. I think using both methods is smart. If I had to chose one, my e-stop would kill my main contactor and it does.

Come on PJ. It's there in case you push the big red button without the feed being connected to a gfi breaker. The resistor fries or the fuse blows...what's the difference? I will convince you someday...

You came damn close to me shutting down all of my diagrams. (Because of your close affiliations with a significant moderator.)

Do what you gotta do...

I have no knowledge of that. It was certainly not my intent. I'm just here offering my opinions with an open mind in case I may learn something (and I definitely have). We disagree on some issues. So be it. No hard feelings on my end.

If something happens and a lot of liquid falls on my panel - maybe I have a carboy shatter on me, who knows... I want to secure all power.

Really, we're arguing whether it's necessary to kill power in a few feet of supply line. I figure if I'm going to do it, may as well do it all. If shunt trip breakers weren't $400 I'd kill power all the way to the main panel. At least with the leak current I kill power back to the spa panel.
