I have left my code book at the office, and my friend has a question regarding a 50amp hot tub. Does it need #6 ground minimum. He has 30meters of 3c#6 Teck, but the ground is a #8. Anyone got the 2015 code book to hand?
I don't have my code book in front of me to provide the reference, but manufactured cable assemblies are considered to have a bonding conductor sufficiently sized for that cable. So your friend will be fine.
