Can 6mm take 40a?
2 Answers from MyBuilder Electricians 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.
Can you replace a 7.5 kW shower with a 8.5 kW?
A 7.5kw shower can be supplied using a 4mm cable, but for 8.5kw, you will need at least 6mm cable. Changing the fuse/circuit breaker would allow the shower to work but the cable could overheat and presents a fire risk.

Can a 6mm cable be used on a 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.
Can I run a 10.5 kW shower on 6mm cable?

What size fuse do I need for a 9.5 kW shower?
A 9.5kW shower should be installed with 10mm2 cable with a fuse rating of 40-45A, NOT 6mm2 ! It should also be RCD or RCBO protected.
Can you replace a 8.5 kW shower with a 9.5 kW?
3 Answers from MyBuilder Electricians A 10mm twin and earth cable on a 40 breaker is adequate for a 9.5 kw shower as long as it is protected by a 30 ma rcd.
How many kw can a 4mm cable carry?
For example, in optimum conditions, sheathed multi-core p.v.c.-insulated 4mm^2 cable could safely support a load of up to 8640 Watts at 240V. In adverse conditions, the same cable might safely support a load of no more than 5520 Watts. Tim Cooke, Construction Worker.
Can I replace a 9kw shower with a 9.5 kW?
you don’t have to change the wiring, what you have will do fine. just check that the mcb is big enough, some electric showers call for 45 amp – though if you are going down from a 9.5 to a 9kw it should be fine.

Yes you can. BUT, I would be inclined to put a FCU on the end of the 6mm cable then run a 2.5 mm cable to where ever you want.
Can I fit a 8.5 kW shower on a 6mm cable?
