Notes:
1. All line and low voltage wiring must adhere to the National Electrical Code and local
codes, whichever is the most stringent.
2. In determining the correct supply wire size and maximum length, reference NFPA
70, Section 310. If the calculation is close to the maximum allowable ampacity of a
particular wire size, use the next size up. This will ensure that no adverse effects
occur, such as light dimming and/or shortened compressor life.
3. Min/Max Voltage: 208/230/60 = 187-252
