20A isolator switch in shower circuit.

[essexman]

Having trouble with a isolator switch.

Fitted 20A D.P isolator switch in a shower circuit and the switch has failed. This is the second one I've fitted of the same type as the first failed aswell.
Shower is 8Kw. Should this happen, or should i have fitted 45A.

Any ideas,
Thanks.

This has to be a wind up

Helpful.

If you were qualified you could do this in your sleep :shocked:

If it isn't a wind up #2 post is the best advice you'll get mate.

I guess there's nowt on telly so your up for a windup.

Would this be the same shower you put 50A in for ?

 

[essexman]

No, and ive just read my first post, typo 5kw, Know it would draw 21A but thought 20A would be ok. Sorry for upsetting everyones evening.

 

[needasparks]

I would think you know the answer to this, even the isolator is telling you. come on man.

 

[essexman]

Yeah point taken, thought 21A would be absolute max, if running very hot ect. I will go and hang my head in shame now.

Whilst you're hanging your head, nip along to Specsavers, 5kw seems a little low for a shower.

I bet he regrets starting this thread you guys don't take prisoners awhoo!

you have to consider your supply voltage, from your supply voltage you calculate the current that your circuit takes. the current needed by the circuit should not exceed the rated current of the isolator. if the current needed exceeds the rated current of the isolator, change the isolator to one with a bigger value.

Come on guys give the guy a break, the 20A switch is probably flush in the nice new bathroom next to the flush mounted light switch and those 45A ones can be big and ugly looking.
