Electric shower wiring

by Carbs » Mon Jul 16, 2007 10:01 pm

We've been in our new house for going on a year now and I've recently noticed that the 10.5kW electric shower that was here when we moved in is wired using 6mm cable. On top of this, its wire type fuse on the consumer unit is only 30A.

My understanding is that a shower with that rating needs a 45A fuse and 10mm cable and whilst it has been working fine so far, I am now paranoid that something is going to burst into flames at any moment.

Can anyone help?

Thanks Blakey1963

Does this mean that the current set up is dangerous? Should we stop using the shower?

OBVIOUSLY THE UNIT WILL OPERATE UNDER CURRENT SET UP
BUT THE 6MM2 IS UNDER RATED AND BE INCREASING IN CONDUCTOR OPERATING TEMPERATURE WHEN SHOWER DRAWING
FULL CURRENT. PROTECTIVE DEVICE IS ALSO BEING ALLOWED TO
CARRY EXCESSIVE CURRENT ABOVE ITS RATING, SO IT WOULD BE A GOOD IDEA TO REFRAIN FROM USING THE SHOWER AND GET THE
WORK CARRIED OUT ASAP.

Make sure also that the shower is earthed properly.
