3.1.3 Power Cables
The UPS can generate large leakage currents. A circuit breaker that provides leakage

If multiple UPSs are to be connected in parallel, input and output power cables for each
UPS should have the same length and specifications.
The currents listed in the following table are measured at a rated voltage of 200 V.
