Diversity (hot tub) & (sauna)

[The apprentice]

Hello there, I have a sub main in a small bunker that is supplied from an in house 50A supply that then supply’s a 6mm2 SWA that supply a small board that feeds a sauna and hot tub and also a 32 A commando socket and some small led lighting they are Adding in 2 x 3kw Emerson’s for a shower can I add diversity to this or not ? 100% then 80% after ?

Hmm, 50A is more than 6mm SWA is typically rated for if 70C limit applied, so unless your stuff is 90C rate (and XPLE cable) then a bit dodgy!

I can see a hot tub being on for a long time, so I'm not sure how much diversity could reasonably be applied to that load. LED lights probably can be ignored.

Sorry 50A supply’s the sub board then from that 6mm2 40A breaker supply’s another sub board to feed sauna and hot tub

It might be pushing it for extra load.

You can set a timer for immersions, but the hot tub is basically on all the time… you can’t predict when it’ll draw power…. Although it does try to heat up whenever the cover is taken off or a relatively cooler body goes in.

Just have a cold shower. It’s supposed to be healthy to go from hot to cold.
