if a RCD trips and needs resetting, is there always a fault/reason why it trips? or can the rcd itself just become faulty?
Thanks for your help again
Thanks for your help again
is it true they trip due to a difference between live and neutral? what exactly does that mean! or due to an earth leakage? again, what exactly is that in laymans?
how do you check for a faulty appliance if it causes a RCD to trip?
insulation resistance.
ok thanks - i understand, so basicaly you test between live and neutral, live and earth, neutral and earth and want a very low ohms reading?
