If a motor has leakage current, will it trip a GFCI breaker? Should that leakage current be there or is there

Question

something wrong with the dryer motor? How come a blow dryer doesnt have leakage current? How come a washing machine doesn't trip a GFCI receptacle? It has a leakage current too?

Answer 1

leakage current doesn't exist. a motor works on a set amount of current. if the voltage is low, the motor will go bad before it should. a gfci plug or breaker trips when the circuit goes to ground, or when the circuit is overloaded. the gfci plug and breakers usually only are put on the kitchen, outside, and bathroom plug circuits to preotect you from accidental electrocution, but it isn't always successful when something like a blow-dryer or tv falls into a tub of water.
a washing machine is not on a gfci circuit unless you make it one by installing a gfci plug or breaker on the circuit which the washing machine is on.
occasionally a plug has a bad wire connection which keeps it from having a normal circuit voltage, but it isn't leaking, it because a partial ground in the wiring has developed such as a partially bare wire inside the wall.

A GFCI breaker measures the instantaneous difference in currents for the two conductors going to an electrical device. Normally, the currents are equal, but in opposite direction. If there is an imbalance, it indicates that there is a "leak". This leakage current is taking another path through the ground back to the source of the power. Since a human may be part of this leakage path, the GFCI is designed to trip, turning off power to the device. Thus the name, Ground Fault Circuit Interrupter.

The windings of a motor, as in a blow dryer, are made with magnet wire, which is copper wire with a thin enamel insulation. If the motor overheats, the insulation may break down and create a leakage path. A leakage path could also result from the internal connections of the motor getting wet. But under normal conditions there is no leakage current in the motor and the GFCI should not trip.

This page can answer your question better than I can.

There is nothing wrong with the motor. All motors have inductance. The GFCIs that come on a hair dryers are designed to not trip from the motor.

You may not even get nuisance tripping, but it is a possibility.

Answer 4

GFCI (ground fault circuit interupter) is designed to trip in the event of an electrical short, not leakage.

Answer 5

Yes I do. The only people calling for Holder's resignation are hateful Conservatives.

Answer 6

i think the problem is bad rollers.
