NOTES: 1. Main power must be supplied from a field-supplied fused electrical service with a (factory-or field-installed) disconnect located in sight from the unit. 2. Control circuit power must be supplied from a separate source through a field-supplied disconnect. The control circuit accessory transformer may be applied to power from the main unit power supply. 3. Maximum incoming wire size for each terminal block is 500 kcmil. 4. Maximum allowable phase imbalance is: voltage, 2%; amps, 5%. 5. Units with one MCA value have one main terminal block. Units with 2 MCA values require multiple conductors. 6. Use copper conductors only. 7. The MOCP is calculated as follows: MOCP = (2.25) (largest RLA) + the sum of the other RLAs. Size the fuse one size down from the result. The RLAs are listed on the unit nameplate. The recommended fuse size in amps (RFA) is calculated as follows: RFA = (1.50) (largest RLA) + the sum of the other RLAs. Size the fuse one size up from the result. The RLAs are listed on the unit nameplate. 8. Units have the following power wiring terminal blocks and parallel conductors: VOLTAGE TERMINAL BLOCKS OR NON-FUSED DISCONNECTS PARALLEL CONDUCTORS OR NON-FUSED DISCONNECTS 208/230 2 6 460 1 3 575 1 3 380** 1 3 230 2 6 346†† 1 3 380/415 1 3 18 Table 5A — Compressor Electrical Data, 30HXC Units UNIT SIZE 30HXC NAMEPLATE V-Hz (3 Phase) COMPRESSOR NUMBERS A1 B1 RLA LRA RLA LRA 076 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 * 44.3 35.4 53.7 * * 55.8 * 330 264 365 * * 344 * 44.3 35.4 53.7 * * 55.8 * 330 264 365 * * 344 076-WD 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 98.1 44.3 35.4 53.7 92.1 61.1 55.8 209 104 83 115 174 120 109 98.1 44.3 35.4 53.7 92.1 61.1 55.8 209 104 83 115 174 120 109 086 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 * 53.6 42.8 64.9 * * 67.7 * 330 264 365 * * 423 * 44.3 35.4 53.7 * * 55.8 * 330 264 365 * * 344 086-WD 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 118.6 53.6 42.8 64.9 111.8 74.2 67.7 209 104 83 115 213 147 134 98.1 44.3 35.4 53.7 92.1 61.1 55.8 209 104 83 115 174 120 109 096 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 * 65.5 52.3 79.2 * * 81.7 * 405 324 448 * * 506 * 44.3 35.4 53.7 * * 55.8 * 330 264 365 * * 344 096-WD 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 144.9 65.5 52.3 79.2 134.9 89.5 81.7 256 128 102 141 255 176 160 98.1 44.3 35.4 53.7 92.1 61.1 55.8 209 104 83 115 174 120 109 106 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 * 79.2 63.3 95.9 * * 97.8 * 485 388 536 * * 605 * 44.3 35.4 53.7 * * 55.8 * 330 264 365 * * 344 106-WD 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 175.4 79.2 63.3 95.9 161.7 107.3 97.8 307 153 123 169 305 210 191 98.1 44.3 35.4 53.7 92.1 61.1 55.8 209 104 83 115 174 120 109 116 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 * 79.2 63.3 95.9 * * 87.8 * 485 388 536 * * 605 * 53.6 42.8 64.9 * * 67.7 * 330 264 365 * * 423 116-WD 208/230-60 460-60 575-60 380-60 230-50 346-50 380/415-50 175.4 79.2 63.3 95.5 161.7 107.3 97.8 307 153 123 169 305 210 191 118.6 53.6 42.8 64.9 111.8 74.2 67.7 209 104 83 115 213 147 134 LEGEND LRA — Locked Rotor Amps RLA — Rated Load Amps WD — Wye-Delta Start *Units are shipped with wye-delta start as standard.
