The GFCI operates only if the ground current exceeds a specified level and is held off if the ground current falls below a specified level. The present invention is also related to a power distribution system.
The invention was developed in part in response to the need to protect people from ground faults in such environments as distribution boxes. One method of protecting people from ground faults is to install a ground fault circuit breaker (GFCI) in a distribution box. A GFCI will shut off power to the box if the load becomes grounded. The present invention pertains to improvements to GFCI circuits.
One type of prior art GFCI circuit is illustrated in FIG. 1. The circuit includes a ground fault circuit breaker (GFCI) power supply 1, a power switch (e.g., a power relay or contactor) 2, a GFCI controller 3, and a series combination of a gate resistor 4 and a capacitor 5. The power supply 1 has a number of components (e.g., a power transformer, a rectifier, a filter capacitor, etc.).
When the power switch 2 is closed (e.g., when the power is on), it places the combination of resistor 4 and capacitor 5 in series with a load 6. This combination of resistor 4 and capacitor 5 limits the current to the load 6. If the load 6 becomes grounded, a ground fault
