*Heater capacity (kW) is based on heater voltage of 208v, 240v, 480v, or 600v. 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 equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or
HACR breaker. Canadian units may be fuse or circuit 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 percentage of voltage imbalance.
% Voltage Imbalance
= 100 x
max voltage deviation from average voltage
average voltage
Example: Supply voltage is 230---3---60
AB = 224 v
BC = 231 v
AC = 226 v
Average Voltage = 224 + 231 + 226
3

=
227
=
Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v
(AC) 227 – 226 = 1 v
Maximum deviation is 4 v.
Determine percent of voltage imbalance.
% Voltage Imbalance
= 100 x
4
227
= 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.
3. Single point kits CRSINGLE028A00 and CRSINGLE031A00 are not required if field---supplied
pressure connectors are used. Factory---installed heaters contain terminal blocks when
combined MOCP is greater than 60 amps.
