    The breaker in my den will trip with nothing on except the TV and cable box. I have unplugged them and reset the breaker, then plugged them back in and everything is fine for 3 or 4 days, then breaker will trip again. I just replaced the breaker the outlet and the power strip and the breaker has tripped again. Do you have any suggestions? Thanks for your time on this problem that is running me crazy.

    • Dave Rongey says:

      Hi Keith,
      You have verified that the problem with this circuit is not the breaker, or the surge strip, so the next items to focus on would be the devices that are plugged into the circuit. I would suggest that you make sure that the incoming cable service to the home is properly grounded because an ungrounded cable service has been known to cause problems.
      If your cable service is not properly grounded and the cable box is in fact causing the circuit to trip off, then notify your cable service provider and ask them to come out and correct the problem by making sure the service is properly grounded. Be aware that problems with the TV can also cause problems with the cable system as well. Explain the history of the problems to your cable service company and they will perform a few tests to isolate the problem.

      If the TV or cable system is not the problem, then I would identify any other devices that remain on the circuit and examine them to see if there is anything that would contribute to this problem. You could carefully use an extension cord and plug one of the remaining devices into another outlet that is fed from a different circuit. Repeat this process one device at a time until the faulty device has been identified.

      If a device is not the problem, then the circuit wiring will need to be tested and evaluated.

      I hope this helps.
      Dave
