Hi All, Havent posted for a while but would appreciate some opinions..
See pics for hot tub arrangement that I've been asked to provide power for..
A local tradesman had already built this when I was brought in and the clients are existing customers of mine who had booked in lots of other work.
He has used 2 plug and play pump/heater sets that are coupled together in some way and all the pipework within the structure is plastic apart from 2 copper bends as seen in pic.
I have provided power into several adjacent buildings from a remote 3 phase incoming supply. The whole site is on TT earthing.
The structure sits on a steel reinforced slab and is constructed of concrete / natural stone / brick.
There will be no class 1 equipment in zones 0 or 1 (sec 702 applies I'm sure) but I'm sure there will be plugged in stuff everywhere , they are party types and have 4 sons teens/20s.
Bonding..? rebar in slab is inaccessible (builder told me he'd get to it but hasn't yet) but I'm sure it will be an extraneous conductive part..the copper bends are not as tested today but when everything is wet?
In short I have concerns that the design is a bit of a lash-up but need to do the right thing...should I bond or not?
Forgot to say the thing is surrounded by wooden decking which 1 of the sons has peppered with mickey mouse LEDs, thankfully SELV. Cheers John
