Each AC power supply weighs approximately 5.0 lb (2.3 kg) and consists of one AC appliance inlet, an AC input switch, a fan, and LEDs to monitor the status of the power supply. Figure 1 shows the power supply. For existing power supplies, each inlet requires a dedicated AC power feed and a dedicated 15 A (250 VAC) circuit breaker.
For high-capacity power supplies, each inlet requires a dedicated AC power feed and a dedicated 16.0 A @ 100 VAC or 16.0 A @ 200 VAC circuit breaker, or as required by local code.
