To avoid electrical shock, personal injury or death, be sure that field

wiring complies with local and national fire, safety, and electrical

codes, and voltage to the system is within the limits shown in the

job-specific drawings and unit electrical data plate(s). Power supply

to unit must be disconnected when making field connections.

Rigorously adhere to field wiring procedures regarding proper

lockout and tagout of components.

Electric Heating

Table 30 - Standard Motor Electric Heat Capacities, Amps, Wire Sizing, and Over Current Protection

# Amps at unit voltage, 60Hz, single phase

Note: Unit wire sizing should be determined in accordance with NEC and local codes.

* External static pressure ranges must be strictly adhered to.
