Operation of RCD
Posted: March 21st, 2021, 7:35 pm
I have a Wylex WSEM 80/2 ‘residual current operated circuit breaker’ 100mA trip mounted at the side of my consumer unit – it’s been there at least 25 years.
Whenever I need to switch the power back on, sometimes it takes several attempts to get it to latch on, and I have to lift it very gently and slowly. Is this normal behaviour? Obviously if appliances/lighting/heating are switched on, I’m switching a current, but should the switch just snap back on or is it normal to need easing back on?
(I have to switch the power back on with this RCD rather than the consumer unit switch, because switching the consumer unit on trips the RCD.)
