We just had a similar discussion on hot tubs installed outdoors. One supervisor did not feel a equipotential grid was required period based on his reading of 680.43(B). It was, however, generally accepted that a grid was required.
There were two unanswered questions during the meeting however. In 680.42(B) what does" Bonding by metal-to-metal mounting on a common frame or base shall be permitted. " mean ? We could not picture this.
Secondly: How do you guys approach a situation when a newly purchased hot tub is set outdoors on an existing concrete slab ?
