Heating elements only have two poles. The ground actually won't be wired to the element, but probably to either the rims tube, or the box you house your element into.

A random element:

If elements had 3 poles, your two hots and a neutral pole, that would be the case. I'm actually using 4 contactors in my two element build, so I can switch from 110 and 220 on each element (RIMS/BK). Only difference in mine is I'm switching the second legs on your diagram from Line 1 to Neutral. Still, the circuit wouldn't be complete unless the SSR is activated.

Sorry P-J for continuously talking over you. I'll step back. Best of luck Hefty on your build. I've got to go back to trying to seal my element to a tri-clamp fitting. As soon as pressure hits it it gives a slow leak.

Agreed, there's no path there. Even if there was, that current path would trip your GFI.

No sweat what so ever. You are doing just fine and it is appreciated.

Thanks.

Ok, now I'm really confused. What would the current flow be if the SSR is allowing it to do so?

Nevermind.... I GET IT NOW!!! Whew!!! In a 240V circuit, the current doesn't flow back through the neutral, it flows back through the other leg. Therefore, when the SSR is not allowing the one leg to be active there is no path for the other leg to flow. When the SSR IS active, the current flows back and forth through the two legs.

So, P-J's schematic makes complete sense to me now! Back to building...
