MOCP --- Maximum Overcurrent Protection
RLA --- Rated Load Amps
NOTES:
1. In compliance with NEC (National Electrical Code) requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the
overcurrent protective device for the unit shall be Power Supply fuse. The CGA (Canadian Gas Association) units may be fuse or circuit breaker.
2. Minimum wire size is based on 60 C copper wire. If other than 60 C wire is used, or if length exceeds wire length in table, determine size from NEC.
1. Unbalanced 3---Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percentage of voltage
imbalance.
% Voltage imbalance
= 100 x
max voltage deviation from average voltage
average voltage
IMPORTANT
: If the supply voltage phase imbalance is more
than 2%, contact your local electric utility company immediately.
