Electrical Wiring in the Home/POSSIBLE NAIL HITTING WIRE


I was installing a new MDF base board on my stairs and when nailing it to the wall, the light on the ceiling above began to flicker.  There is a pressure sensitive switch with intensity control activated by touching a flat plate located above the point where I was nailing.  Could I have hit a wire or would the shock of the nailing be sufficient to have caused the flickering?  The circuit breaker did not pop.

I have found many wires with brads driven thru them. On the other hand, it may have been the shock of the hammer blows which caused the flickering.
If you are really concerned it will be necessary to open the walls to examine the area where you drove the nails.
There is no other way to be absolutely certain.
