Please put my mind at rest

[Hottub]

hi guys I have had an electrician come and put some wiring in ready for a hot tub delivery.

I passed on a electrical document sent to me by the hot tub company which had 6mm on it.

He has run a armoured 2.5mm 3 core cable from the main board and a dedicated 32amp mcb to an external rotary switch ( about 3 metres away ) also 32amp. From the switch he has run the same 2.5m 3 core around to where the hot tub will be ready to be connected ( no more than 4m away ).

He says its more than enough but as I've seen 6mm on the wiring diagram I'm worried.

So shall I stop worrying? Or demand he use 6mm? Or find a different sparky?

Thank you for your time.

Worked on quite a few tubs where the recommended supply was 6mm² and 32A the reality being with the heater and all pumps running they rarely run above 18 - 20A although the inrush starting the pumps does give a short current spike

there you go complicating the issue. always the negative waves, moriarty, always the negative waves.

Woof woof, that's my other dog impression

Good points made by Wirepuller. I was blindly thinking of 2.5mm T&E max being approx 27A, but obviously different cable types have differing CCCs.

Think he might be in one of those "special" places where you dress up and do role play

It is a quote from the same film as Tel was quoting.
