Is a 8.5 kW shower powerful enough?

Is 6mm cable OK for 9.5 kW shower?

9.5kW is either 39A or 41A depending on the voltage it is rated at. 6mm cable is 47A when installed in the most favourable conditions. So 6mm could be used, depending on how it is installed. However it would be usual to use 10mm which would allow the fitting of a higher rated shower either now or in the future.

What size cable do I need for a 10.5 KW shower?

Re: What size cable for 10.5kw shower? 1) the design current is 45A, so the MCB should be 45A. 2) 6mm T&E cable installed covered by 100mm insulation the maximum current carrying capacity is only 34A. so straight away it is clear the cable is undersized (needs to be at least 10mm).

Can 6mm take 40a?

6mm twin and earth cable (which this almost certainly is) can be backed up by a maximum of a 32a MCB, even lower if other factors are involved. You’ll need that 10mm cable and a 40a MCB unfortunately as your shower is going to draw over 32a. Whoever fitted the 40a MCB onto the 6mm cable originally was in the wrong.
