| 摘要 | An electrical power distribution system (2) includes a main disconnect unit (4) and a surge protector unit (6). The main disconnect unit (4) includes an electrical power bus (8) having a three-phase power bus and a neutral bus. The separable contacts (28,30,32) of a circuit breaker (9) are employed for interrupting current flowing in the three-phase power bus. The surge protector unit (6) includes an electrical power bus (10) having a corresponding three-phase power bus and a neutral bus. Three phase-to-neutral surge protectors (166,168,170) are employed for protecting downstream loads from surges or transients on the power buses. The electrical power bus (10) of the surge protector unit (6) electrically engages the electrical power bus (8) of the disconnect unit (4) to form a series electrical connection of the electrical power buses (8,10) for the loads. | ||||||
