Electric shower pull switch isolator

[clematis432]

Hi, my neighbour has had to change his electric shower (6kw) pull switch (32A) 3 times in 4yrs. Apart from it possibly being poor quality switches he,s replacing, I was wondering if there is any reason not to leave the pull switch isolator in the "on" position. Thanks

Borrow the home owner your hammer and chisel and get them to smash out a chase for you , you then go back later and just put the cables in and connect up the new switch...

He,as auld as me

Whilst I don't want to steal Charlie's thunder, but the point he is making is a valid one, the higher the KW of the shower the bigger the spark should there be a faulty connection, basivc Ohms Law I = P/V 6000/230=26 Amps whereas 9000/230=39Amps
The other points I'll leave to Charlie but I'm sure you get the gist of what Charlie
said cuz I 'm nice like that, shut up TEL.

Yes, but if the switch is rated to take the load, it should be fine ?

If I went to a job where a shower was up to a 4th isolator in as many years and I knew my previous connections were good then I would also inspect the shower and iland test it for any problems.. especially if the shower is only 25 amps

You shouldn’t switch them on and off under flc

Agree without conviction

Yes, think that,s a basic, no offence.

No offence taken. But seen a few thermally damaged cables reconnected causing the terminals etc to fail again. Going back to ‘good wood’, includes the cable that feels stiff, not just ‘clean’.

It was "only" 3 isolators, and I don,t know what could cause an isolator to burn out due to something being wrong in the shower unit ? How could that affect the switch contacts ?

Not doubting your sincerity Clem, but how do you know that? if there is a duff connection then contact burnout will occur. Bite the bullet and fit a decent wall isolator

You said you had replaced it 3 times in 4 years??
Inside shower; faulty components, low ir, reverse polarity could all affect the isolator
