In compliance with NEC requirements for multimotor and combinationload equipment (refer to NEC Articles 430 and 440), the overcurrent pro-tective device for the unit shall be fuse or HACR breaker.2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage isgreater than 2%. Use the following formula to determine the percent ofvoltage imbalance.% Voltage Imbalancemax voltage deviation from average voltage= 100 x average voltageExample: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v452 + 464 + 455Average Voltage = 31371= 3= 457Determine maximum deviation from average voltage.(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v(AC) 457 – 455 = 2 vMaximum deviation is 7 v.Determine percent of voltage imbalance.% Voltage Imbalance = 100 x 7457= 1.53%This amount of phase imbalance is satisfactory as it is below the maxi-mum allowable 2%.IMPORTANT:If the supply voltage phase imbalance is morethan 2%, contact your local electrical utility companyimmediately.POWER EXHAUST ELECTRICAL DATAPOWER EXHAUSTPART NO.APPLICATIONUSAGEMCA(230v)MCA(460v)MCA(575v)MOCPseparatepowersource only)CRPWREXH030A01 004--- 007* 1.6 N/A 0.64 15CRPWREXH021A01 004--- 007* N/A 0.68 N/A 15CRPWREXH022A01 008--- 014* 3.4 N/A 1.32 15CRPWREXH023A01 008--- 014* N/A 1.4 N/A 15CRPWREXH028A01 ALL 1.7 N/A 0.68 15CRPWREXH029A01 ALL N/A 0.7 N/A 15* Single or three phaseN/A — Not availableNOTE: If a single power source is to be used, size wire to include power exhaustMCA and MOCP.Check MCA and MOCP when power exhaust is powered through the unit. Deter-mine the new MCA including the power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 50TFQ006---5 unit with MCA = 35.6 and MOCP = 40, withCRPWREXH030A01 power exhaust.MCA New = 35.6 amps + 1.6 amps = 37.2 ampsIf the new MCA does not exceed the published MOCP, then MOCP would notchange. The MOCP in this example is 40 amps and the MCA New is below 40;therefore the MOCP is acceptable. If “MCA New” is larger than the publishedMOCP, raise the MOCP to the next larger size. In all cases, the MOCP for the pow-er exhaust should be 15 amps per NEC.50HJQ
