Hope this post finds you well.
To answer your question, when operable, no. Knowing what circuit and receptacles are protected is another story all together.
As well, at times, a GFCI device might be slaving receptacles/outlets upstream.
Personally, I test every receptacle I can pernitrate with my EXTECH CT70 AC Circuit Load Tester.
When you encounter a panel GFCI breaker the GFCI, Ground Fault Circuit Interrupters Test Procedure goes as follows. 1: Test the breaker at the source.
1: GFCI panel Breaker: Re-Set a Circuit-Breaker Type GFCI.
A: The first thing you do is toggle the breaker lever to the OFF position. On some models past the OFF position. B: Then reset the GFCI breaker by moving the toggle lever to the ON position.
2: GFCI Receptacles: Press the TEST button in order to trip the GFCI device.
As well, Trip Times of GFCI’s, Ground Fault Circuit Interrupters is important. A GFCI will “sense” the difference in the amount of electricity/current flowing into the circuit to that flowing out, even in amounts of current as small as 4 or 5 milliamps. A GFCI should react quickly. in less than one-tenth of a second, to trip or shut off the current flowing on the circuit outlet.
