How many amps does gfci trip at?
GFCI receptacle are designed to trip on 5 milliamps.
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)
Can rodent damaged romex cause gfci to trip?
Yes
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.

Yes
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.
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.
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.
Why do gfcis trip?
GFCI's trip on an un balance between the current on the "hot" wire and the current on the neutral wire
Will another electrical outlet that is in line with a GFCI outlet cause it to kick off?
A down stream receptacle that is connected to the upstream GFCI will be protected. If the downstream receptacle senses a fault the upstream GFCI will trip.
