A terminal fault is a fault that occurs at the circuit breaker terminals. A single receptacle is cheaper than provding this GFCI protection at the circuit breaker. Troubleshooting followed and indicated the problem was related to "transient contamination" in a circuit breaker. It is achieved with the help of a circuit breaker and isolators. Other considerations, such as rationalization of the circuit breaker range, can also influence the cost. This provides a far more refined response than circuit breaker switched capacitors. This was the first time that the "circuit breaker" rule had operated. The circuit breaker operates in two stages. The circuit breaker contacts are held closed by a latch. They lock Joan outside when she checks the circuit breaker. The term is often used to refer to circuit breaker panels or fuseboxes. Thus, the EGPWS was de-activated by pulling the circuit breaker. Each sectionalizer detects and counts fault current interruptions by the recloser (or circuit breaker). In the early 1970s most North American GFCI devices were of the circuit breaker type. The ring is fed from a fuse or circuit breaker in the consumer unit.
