*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, or 480 v. If power distribu- tion voltage to unit varies from rated heater voltage, heater kW will vary accordingly.
†Fuse or HACR circuit breaker.
NOTES:
1.In compliance with NEC requirements for multimotor and combination load equip- ment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker.
2.Unbalanced
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.
max voltage deviation from average voltage
% Voltage Imbalance | = 100 x |
average voltage
Example: Supply voltage is |
| |
AB = 224 v |
| |
BC = 231 v |
| |
AC = 226 v | 224 + 231 + 226 | |

Determine maximum deviation from average voltage.
Maximum deviation is 4 v.
Determine percent of voltage imbalance.

= 1.76%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
