Shower 32amp breaker

Former Community Member
Former Community Member
I’ve now seen this a few times, an 8.5kw shower on 6mm t&e with a 32amp breaker.

My question is:

Why do electricians do this, and is it detrimental to the breaker?

    So from the above help, it seems that this is not an uncommon occurrence. And not detrimental to the MCB

    To add more detail, the installation that I refer to is a replacement CU. previously the shower was on a  B40 MCB, cable method is 6mm t&e clipped direct with no insulation. Cable run is approximately 10m


    The shower is also using around 38A according to my clamp meter
