Electrician Jobs TT supply for hot tub

[gcwarr]

Hi,

I have recently had a hot tub fitted and am not comfortable with it being supplied directly from TN-C-S supply. I’m looking for someone to modify to TT, but struggling to find anyone locally who can help.

Location - Warrington, Cheshire.

Thanks.

Hi GC,
Could you explain your worries a little more?
It's unusual for a customer to even know what TNCS is, you clearly do and you are worried about it. Did you discuss it with the electrician before hand?
I haven't checked the most up to date regs on this, but did find the following from an (older) NICEIC article...

"Hot Tubs and TN-C-S Supplies The NICEIC Technical Helpline is often asked whether a hot tub installed outdoors may be supplied from a circuit taken from an installation forming part of a TN-C-S system, often referred to as a PME Supply. Neither the Electricity Safety, Quality and Continuity Regulations nor the guidance given in Engineering Recommendation G12/4 – Requirements for the Application of Protective Multiple Earthing to Low Voltage Networks published by the Energy Networks Association places any restrictions in respect of the connection of a hot tub to a PME supply. G12/4 does offer several alternatives in respect of the connection of a swimming pool to a PME supply and it is sometimes suggested, erroneously, that hot tubs should be treated in the same manner as a swimming pool. However, it is clear that hot tubs fall outside of the scope of Section 702 of BS 7671 (see Regulation 702.11). So, unless, as stated previously in this article, a hot tub outdoors is installed within the zones of a swimming pool, only the general rules of that standard are applicable."
