The electric motor for the power unit requires 220 Volt (single phase) 60 Hz (+/- 5%, so 209-231 volts). We recommend using at least a 10 gauge (grounded) wire from the electrical panel. The power unit may or may not have a short pigtail (no plug) that can be wired to either an optional quick disconnect box (mounted on the lift column) or to a male/female plug combination. A 30 amp breaker is required.
