50 amp GFCI breaker for Hot Tub

[Dennis Alwon]

"For instance a spa will have both 120v and 240 loads. Spa GFCI's do not trip when only 240 loads are utilized."

The poster said there was no neutral in the spa. Would a spa maker really not put in a neutral when the spa also has 120V loads,instead relying on the ground to carry neutral current? Sounds ridiculous for a wet environment. Maybe this particular spa doesn't have any 120V loads(lighting,etc)?

I don't think they use the ground but rather just have 240V loads.
