[PartyCan]

Can any one tell me if a 40 amp mcb is ok for a 9.5 shower or do i need to change it for 45 mcb.

Have no problems with the shower just like to no if the 40 is ok for peace of mind thats all.


Cheers and Thanks for any info.

I would say you need a 45A MCB. Do not uprate the MCB unless you are absoloutly certain the caple is capable of carrying this current. (not forgetting to apply any derating factors)

9500W / 230V = 41.30A

Check the small print of the shower.

If, as is 99.9% certain, it says 9300W at 240V, 8500W at 230V, then your 40A breaker will be fine.
