LEGEND AND NOTES FOR ELECTRICAL DATA TABLES
LEGEND
*Used to determine minimum disconnect per NEC.
†Heater capacity (kW) is based on heater voltage of 208 v, and 480 v.
If power istribution voltage to unit varies from rated heater voltage,
heater kw will vary accordingly.
**Fuse or HACR circuit breaker.
††Optional disconnect switch cannot be used.
***Units have 2 outdoor fan motors.
NOTES:
1. In compliance with NEC requirements for multimotor and combina-
tion load and equipment (refer to NEC Articles 430 and 440), the
overcurrent protective device for the unit shall be fuse or HACR
breaker.
2. 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 percent
of voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
= 457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%
This amount of phase imbalance is satisfactory as it is below the
maximum allowable 2%.
