What is the trip time for a GFCI?
The trip time for a GFCI is from 15 to 30 milliseconds.
I have a 15 amp tool hooked up to a 15 amp breaker- This trips the breaker even with nothing else running- There is also a GFCI outlet on the same circuit- Is the breaker or GFCI bad?
A 15 amp breaker will trip at 15 amps at an ambient temperature of 104 degree F. If the ambient temperature is higher the breaker will trip before 15 amps and if the ambient temperature is lower the breaker will trip after 15 amps. I would suspect the circuit is overloaded. But, you can change the breaker and see what happens. Just swap it with another one.
Will a GFCI outlet trip when the current is reduced or shut off?
The GFCI is measuring leakage current to ground, so if no current is flowing it won't trip.
Why won't the GFCI trip the panel box when shorted?
A GFCI is not an overcurrent protection device. It only protects people from electrical shock. However, if you were to create a perfect hot to neutral short the GFCI would not trip and the panel breaker would.
What happens when you plug a GFCI protected extension cord into an outlet that is GFCI protected?
In a word NO, that will not cause either GFCI to trip. The correct term is GFCI (Ground Fault Circuit Interrupter)

What happens if you trip a GFCI repeatedly on purpose?
Every time you trip the GFCI, the power to the device plugged into it will lose its supply voltage.

If I have 20 amp GFCI receptacle and would like to add another receptacle to the GFCI Does the new plug also need to be 20 amps?
Yes.

Can rodent damaged romex cause gfci to trip?
Yes
Plugging an electric heater into a GFI outlet caused the lights and other outlets to go out but didn't trip the circuit breaker why?
A GFCI receptacle can pass it's "protection" to other outlets wired from it. If the GFCI trips, all outlets wired from it will "trip" also. A GFCI tripping will not necessarily trip the circuit breaker in the service panel.
Can a difference of 5 milliamperes for 30 milliseconds trip a gfci?
Yes it can.
Will starting current on a motor trip a gfci breaker?
A GFCI measures difference in output to return current. A Overload breaker in your panel is what trips from too much current. many are time delay and will not trip immediately from the less than a second of start up current spike.
How much amperage is needed to trip a 20amp GFCI outlet?
A GFCI trips when it detects a difference in the amperage going to the outlet and what is coming back. Even 4-6 miliamps difference will trip the outlet.
