NOTES:
1. Extensive motor and electrical testing ensures that the motors can be
utilized with confidence up to the maximum applied bhp, watts, and amps.
Using the fan motor up to the maximum ratings shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not be af­
fected.
2. Convert bhp to watts using the following formula:
watts =
bhp (746)
motor efficiency
3. The EPACT (Energy Policy Act of 1992) regulates energy requirements
for specific types of indoor‐fan motors. Motors regulated by EPACT include
any general purpose, T‐frame (three‐digit, 143 and larger), single‐speed,
foot mounted, polyphase, squirrel cage induction motors of NEMA (National
Electrical Manufacturers Association) design A and B, manufactured for use
in the United States. Ranging from 1 to 200 Hp, these continuous‐duty
motors operate on 230 and 460 volt, 60 Hz power. If a motor does not fit
into these specifications, the motor does not have to be replaced by an
EPACT‐compliant energy‐efficient motor. Variable‐speed motors are exempt
from EPACT compliance requirements. Therefore, the indoor‐fan motors for
Carrier 48/50PG03‐14 units are exempt from these requirements.
