Recommended Cable Sizes for Easy UPS 3S

DANGER
hazard of electric shock, explosion, or arc flash All wiring must comply with all applicable national and/or electrical codes. The maximum allowable cable size is 185 mm². Failure to follow these instructions will result in death or serious injury.

NOTE: Overcurrent protection must be provided by others.

Cable sizes in this manual are based on:

Single core cables type U1000 R02V
Specific to AC cables: Maximum length 70 m with a line voltage drop <3% installed on perforated cable trays, XLPE-type insulation, single layer trefoil formation, THDI between 15% and 33%, 35 °C at 208 V grouped in four touching cables
Specific to DC cables: Maximum length 15 m with a line voltage drop <1%

NOTE: If neutral conductor is expected to carry a high current, due to line-neutral non-linear load, the circuit breaker must be rated according to expected neutral current.
