System Wire Sizes & kVA Load Characteristics
• Calculations based upon nominal voltage, wire size in AWG. To convert to mm2, refer to Table 5-2.
• Recommended feeder sizes from distribution transformer to the power cabinet.
• Neutral must be terminated inside the main disconnect panel and not at any GE cabinet.
• The grounding conductor will be of same size as the feeder wires. This ground will run from equipment back to the
facility power source / main grounding point and always travel in the same conduit with the feeders and neutral.
