I tried searching....thought I’d seen before but no luck....
packaged hot tub will be ground level on concrete or pavers. 680.42 (B) says don’t need perimeter bonding if 28” from rim to surface for 30” horiz....
this would apply except existing wood deck might be along one side of unit. Does that mean that surface needs the bonding, and if so how do we run the bond with the wood(attach to underside of wood decking.....seems not very effective)?
thanks, bruce

Well I list handyman because I am retired. I was an electrician back in the day. I raised the question because I faintly recall a discussion in the past about wood decks less than the 28” requirement because the tub was recessed in the deck or similar. Will check with the authority but wanted to be best informed.
