PE advice by Napit (hot tubs)

ebee

There is an article in PE and I have just received it via email.

I am disappointed that the article seems to suggest that it contains all you need to know yet no mention is made of earthing systems

    agree no  mention of TT, TNC-S or step voltages seems remiss

    Pretty sure NIC did a webinar a while back about hot tubs and said it was ok to use the PME earth, i think because there was no exposed metalwork on them but can't remember . Have to say i wouldn't personally.

    You may find this article in IET Wiring Matters more useful.  

    https://electrical.theiet.org/wiring-matters/years/2021/86-july-2021/hot-tubs/

    It does cover PME earthing.

    If you register with the IET to receive Wiring Matters it will come to you via an email.

    Try again.

    Is that true for ALL hot tubs? I saw a TV series this week about the subject, and there was a stainless-steel hot tub … also, there are exposed-conductive-parts on some heaters used in the devices ?

    I think the real situation is far more tricky to navigate.

    Indeed, the odd hot tub that I have encountered had submerged immersion heaters in the water flow that supplied the tub that people sat in.
