Methods For Installing Hot Tub Electrical Cable
Electrical Question: I’m running wire to the hot tub located in my backyard.
Can I run regular 6AWG 3 conductor plus ground through 1″ conduit or do I need to run outdoor 6AWG wire?
I am thinking that regular indoor wire run through conduit is OK.
Also, to my understanding, the wire must not be buried and be above ground by at a minimum height.
This electrical question came from: Mike, a Homeowner from San Diego, CA.
