    When I switch my light off I can see a very faint spark in the bottom left side of the switch. Is this dangerous? Do I need an electrician or is it an easy fix that can be done on my own. It only sparks when I switch it off.

  2. Dave Rongey says:

    Hi Andrew,
    From what has been described, it appears that the electrical wiring has been drilled into and sustained damage which caused the circuit breaker to trip off. Therefore, and for the sake of safety, the portion of the wall where the work was being done should be opened so the electrical wiring may be inspected, and then repairs should be made as needed.
    I hope this helps,

    Last night I was installing a shelve to a wall and when I drilled a screw on the wall (using a driller), I saw some sparks on the light switch (we opened the plating to find the stud) and then the lights turned off. I went for the breaker and turned it back on and it’s all working now.

    Should I be concerned? Please let me know what to do.
