Electrical Outlet Circuit Problem
Electrical Question: Why does an outlet cut out and then it comes back on?
I have this outlet that has a Yamaha or Bose home theater receiver that when I raise the volume below -30 dB, the power in the outlet blows the circuit. The receiver is 400 watts.
- I switch them from time to time, but they are never plugged in at the same time.
- The Bose will cut the outlet at about the same volume.
- The outlet will cut but then about 30 seconds later, it comes back on, the circuit never trips, even after I check.
- I do have a dehumidifier on the same line, and I think that it blew the circuit and permanently damaged the line.
- The dehumidifier has tripped the circuit but the problem was gone after I turned the dehumidifier off.
- The outlet persists to cut out with the dehumidifier unplugged.

Common Receptacle Outlet Problems and How to Fix Them
- Inspecting Outlets
This circuit should be turned off and then all of the outlets on this circuit would need to be removed so that the electrical wiring can be inspected which will no doubt revel a loose or deteriorated connection or a bad splice.
- Heavily Used Outlets
Special attention should be given to the outlet where the dehumidifier is plugged into and the outlet in the surrounding areas.
- Quick Connect Outlet Problem
If the outlets have quick connect wiring where the wires are pushed into the back of the outlets then there may be a connection that has deteriorated.
- Replacing and Repairing Burnt Wiring
If this is the case then the outlet will need to be replaced and the wiring repaired as needed.
- Connecting to Screw Terminals
The quick connect feature should not be used where high watt devices are used such as space heaters and dehumidifiers.
- Pig Tailed Wire Splices
Instead the individual wires should be pig-tailed or spliced so that the circuit does not floe thorough the outlets.
