    Hot tub service disco

    I have a hot tub install coming up. While I was doing the survey for the job, I observed that the customers house has Aluminum siding. So I was wondering what type of bonding/insulating (if any) I might have to do,when I mount my service disconnect,to the siding. I could probably find a pvc disco box. Or I can Isolate the metal disco box from the siding. Thanx

    I am less concerned about the spa disconnect being attached to a metal surface as it should be at same potential as the spa, what may be imposing an difference of potential on that siding elsewhere is what concerns me more.
    I live for today, I'm just a day behind.

      why is a metal box an issue?
      see NEC 2014 680.26

      the box would essentially be bonded to everything else at some point.
