Three reasons I can think of. Improperly wired to much voltage plugged into it or it has a short. Make sure that the plug is not wired in line with plugs down the line. It should have jumper wires going from the circuit to the plug or it is gonna trip everytime. Also if the gauge of wire is too small it is gonna trip. Make sure if it is a 120 volt circuit that it has 12 gauge wire going to it. Hope this helps you. Good luck.
In a word NO, that will not cause either GFCI to trip. The correct term is GFCI (Ground Fault Circuit Interrupter)
You might be overloading the circuit. What else is drawing power on that circuit or phase? Are your lights really OK or is there a short somewhere?.
The trip time for a GFCI is from 15 to 30 milliseconds.
GFCI receptacle are designed to trip on 5 milliamps.
Yes you can. Lots of blow dryers have GFCI protection built in.
Every time you trip the GFCI, the power to the device plugged into it will lose its supply voltage.
GFCI (or Ground Fault Circuit Interrupter) should always be installed anywhere there is a possibility of the "plug-in" getting damp or wet, such as the Kitchen or Bathroom, also it doesn't hurt to use a GFCI in rooms used by children as they trip much faster on a fault than circuit breakers (if the kid sticks something in the plug in)
The GFCI is measuring leakage current to ground, so if no current is flowing it won't trip.
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.
Yes
my gfci trips when my christmas lights r on and it rains is the gfci bad or is this normal of a perfectly working gfci
GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.
