Wiring system for commercial refrigeration

摘要

A wiring system for commercial refrigeration permits multiple refrigerated merchandisers to be wired on a single electrical circuit from a circuit breaker power source. The hardwiring of the system is done at the factory so that three-phase power connection of the merchandisers to a power source can be accomplished primarily by plug-in connectors at the installation site. Overcurrent protection of the merchandiser components can be provided where electrical power is branched off from a high current feeder line. The wiring system also permits power to be balanced among three phases of electrical power.
