Make Jeff happy and ramp up some electrical...

So 680.40 Says Parts I and IV apply....

680.42 says that I and II apply EXCEPT....A and B

Anyone think that the exception to use 680.42 tells you to use 680.42B for outdoor hot tub bonding or do you go back to 680.26?


Part IV. Spas, Hot Tubs, and Permanently Installed Immersion Pools
680.40 General.
Electrical installations at spas and hot tubs shall comply with the provisions of Part I and Part IV of this article.

680.41 Emergency Switch for Spas and Hot Tubs.

This requirement shall not apply to one-family dwellings.
