Hey peps.
As on many occasions doing my electric shower repair rounds, I came across a faulty DP 40a pull cord shower isolation switch.
Why it is I always get a reading of about 70v between L-N load side when these switches fail.
It's always puzzled me why not 120v or 180v......nope always the 70v mark.
And the reading between N-CPC is 200v ? Why is that.
Could someone please explain the reason for this and what is actually happening inside the isolator switch for me to get readings like this.
Thanks.
