    Changing a ceiling light

    Electricians

    Hi, I’m trying to change a ceiling light, but when I turn off the main switches on the electrical panel the tester pen still lights up when I touch the earth wire(green and yellow) what should I do to make this as safe as possible?

    "Hi

    Call an electrician.

    How have you isolated light? From switch on wall or the whole circuit via RCD etc?
    Pen tester not really the ideal took as it may be picking up line conductor.
    Is it a multi switched light? Check connections."

    "Don’t use a test pen as a tester and get a qualified electrician to change the light as it sounds like you may have a fault on the wiring in your property"
