Shower switch

[buildersbutt]

Hi all, have an electric shower downstairs next to a utility room where the consumer fuses are, the shower has a 45amp mcb (on 10mm cable) which is also used to isolate shower when not in use. My question, is it ok to use like this or doe's there have to be an isolation switch in between the shower unit and the mcb, we do switch off at the mcb when shower is not in use. Thanks for your time.

Hi,

It is advised you have a double pole switch to turn off - this must be according to bathroom zones - best bet would be to have a DP switch outside the room to prevent moisture entering it.

As sparkojon says, you will be better fitting a wall mounted iso switch outside the room. The mcb will only isolate the line side of the cable.

Good job Zaire's finest isn't here.

He's been very quiet recently.
Maybe he has been eaten by something that disagreed with him?

He does seem to have been a bit of a seagull of late

Still - let's not get into generic criticisms of people - I should really have added a to what I wrote in the post above.

No reason you can't fit a shower pull switch in the bathroom in a safe zone, of course.

Afterall, that's what they're designed for; and sometimes this arrangement is far more convenient.

Please do not take it to heart.
I would personally feel a sense of loss if you were to top yourself.

Is there a need to install a switch at all, let alone a DP one?

Do the regs allow SP switching in this case?

That's been tried before.

It doesn't go well.

Yes there is a need as clearly stated in the regs and they should be DP.

Will you please quote the regulation(s) which state that.

If local isolation was not required then all that would be required in any building would be a main isolator to switch off all the fuseboards. Think of the money that would be saved by not installing isolators. Think of why
the large electrical contractors always install isolators for all eqipment.

Using terms like "all the fuseboards" and "large electrical contractors" seems to imply a very different environment to an ordinary domestic dwelling.

In those there usually really is only one main isolator to switch off all the fuseboards because there is usually only one fuseboard.
