Maximum Overcurrent Protection

{Motors are designed for satisfactory operation within 10% of normal voltage shown. Voltages should not exceed the limits shown in the Voltage Limits column.

NOTES:

1.Minimum circuit amps (MCA) and MOCP values are calcu- lated in accordance with The NEC. Article 440.

2.Motor FLA values are established in accordance with Under- writers’ Laboratories (UL). Standard 1995.

3.Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the formula in the example (see column to the right) to determine the percentage of volt- age imbalance.

4.Installation with Accessory Electric Heaters

Size the Field Power Wiring between the heater TB1 and the 40RU indoor fan motor per NEC Article 430--- 28 (1) or (2) (depends on length of conduit between heater enclosure and 40RU power entry location). Install wires in field--- installed conduit.

Example: Supply voltage is 230-3-60

% Voltage Imbalance = 100 x

max voltage deviation from average voltage

 

average voltage

 

AB = 393 v

BC = 403 v

AC = 396 v

Average Voltage =

Determine maximum deviation from average voltage. (AB) 397 – 393 = 4 v

(BC) 403 – 397 = 6 v (AC) 397 – 396 = 1 v Maximum deviation is 4 v.

Determine percent of voltage imbalance.

= 1.5%

 

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.
