Do not assume ANYTHING when dealing with a deadly combination of 120VAC and the pool/spa.
It is not worth killing yourself or somebodies kids because you "think" the pool is correct.
Either hire an electrician that specializes in pools or call the county/city inspector to see if there were permits and inspections. If there is no inspection, see the first line of this post.
This is nothing to blow off...
So a regular licensed electrician couldn't come look at it? Is there such thing as licensed "pool electricians?" This is our first pool, so I'm still learning it all. Thanks!
