Why do houses have a switch to turn the shower off, either a

Can't be for safety - if you're in the shower and get a shock,
if
you've
managed to get out to reach the switch, you've got away from it
anyway.

Can't be to isolate to work on it, there's a fusebox for that.

Don't need to turn it off when you're finished showering,
there's
a
switch on the shower itself.

If I answer this, do you promise to **** off?

It's so somebody not in the shower can isolate it quickly before
helping
the poor bugger who is being electrocuted.

I wonder why there is a requirement that the switch indicate
whether
it
is
on or off even when there is no power, i.e. pull switches need a
0/1
indicator (or similar), not just a neon?

So you can see if its off when it has been turned off in the CU and
you are about to turn it on again in the CU. A neon can't do that.

Under what circumstance would you need this?

If you have been working on the shower, have turned it off in the CU
to do that, and want to be next to the shower when you turn it on
again so you can burn it off again if it looks like you have ****ed
up
what you have done and want to stop it destroying itself so you
can fix what you ****ed up before turning it on again.

Then remember whether you turned the isolator switch off first.

Not necessarily possible if it died and you turned it off to fix it.

Anyway the above doesn't work when the switch is in the hall.

But does when it isnt. It doesn't need to have a pull cord when
its in the hall and you can see the position of the switch.

Easy, turn it on and listen for an explosion, if there is one, you did
it
wrong.

And if there isnt, you may still have done it wrong.

But that wrongness isn't so urgent.

Can still burn it out so you need a new one
and may not do any unfixable damage if
you notice it as soon as its switch on and
switch it off.

Turn it off and buy a new shower.

Makes more sense to turn it on when closer and turn
it off again and redo it properly when there is a problem.

Makes even more sense to do the repair properly in the first place.

Sure, but most have enough of a clue to realise that they arent perfect.

You'd have to be pretty stupid to connect it up so it destroyed it.
