A new electric kettle apparently caused a loss of power in a circuit. The circuit is one of two 120V/20A lines protected by an Intermatic PanelGuard model IG1240R surge protection device (SPD) at the panel. (This appears to be an older model. A similar device is described at http://www.intermatic.com/Products/SurgeProtectiveDevices/IG_Series/IG1240RC3.aspx.) The circuit breaker was not tripped, nor did either of the line monitor lights on the SPD go out (indicating it thinks it is working properly).
I have been unable to restore power to this circuit. Of course the kettle was immediately unplugged (and seems to be working properly on a different circuit). All I can see to do is make sure all connections at the panel are secure and to flip the circuit breaker switches off and back on. I cannot open up the SPD itself and it has no external controls--only its two monitoring lights. Testing with an ohmmeter at the receptacle shows continuity. The voltmeter verifies no current at the receptacle, but there is current between the circuit breaker and the SPD. There is current throughout the other line protected by the SPD.
This is the first such loss of power we have experienced in this circuit in the 10 years we have lived here, so presumably it is correctly wired.
There are no receptacle-GFCIs installed on this circuit: just plain 3-prong 2-outlet receptacles. Each has a little label stating it is GFCI protected and refers to "instructions" at the panel--of which there are none.
This all points to a defective SPD, but am I perhaps missing something? What does it take to reset one of these things?
