Abstract
A power delivery system may include a first phase conductor. A power delivery system may include a second phase conductor. A power delivery system may include a neutral conductor. A power delivery system may include a protection circuit including a circuit breaker that opens when a difference between a combined magnitude of current flowing through the first and second phase conductors and a magnitude of current flowing through the neutral conductor exceeds a first threshold.
Claims12
A power delivery system comprising:
- a circuit interrupting device including:
- a first phase conductor,
- a second phase conductor, and
- a neutral conductor;
- and
- a protection circuit including a circuit breaker that opens when a difference between a combined magnitude of current flowing through the first and second phase conductors and a magnitude of current flowing through the neutral conductor exceeds a first threshold.
