A wiring system for commercial refrigeration permits multiple refrigerated merchandisers (10, 12, 14) to be wired on a single electrical circuit from a circuit breaker power source (28). The hardwiring of the system is done at the factory so that three-phase power connection of the merchandisers to a power source (30) can be accomplished primarily by plug-in connectors (118, 128) at the installation site. Overcurrent protection (40, 46) of the merchandiser components can be provided where electrical power is branched off from a high current feeder line (42). The wiring system also permits power to be balanced among three phases of electrical power. |
