Recommended Cable Sizes for Maintenance Bypass Cabinet with Input Transformer

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 4/0 AWG. Failure to follow these instructions will result in death or serious injury.

NOTE: Overcurrent protection and cable lugs are to be provided by others.

Cable sizes in this manual are based on Table 310.15 (B)(16) of the National Electrical Code (NEC) with the following assertions:

90 °C (194 °F) conductors (75 °C (167 °F) termination)
An ambient temperature of 30 °C (86 °F)
Use of copper or aluminum conductors

If the ambient temperature is greater than 30 °C (86 °F), larger conductors are to be selected in accordance with the correction factors of the NEC.

Equipment grounding conductors/Protective Earth (PE in this manual) are sized in accordance with NEC Article 250.122 and Table 250.122.
