Motors purchased in a 110v-1HP configuration typically found on the Hemi Road Runner or our 4-post parking storage lifts will typically pull 13 Amps under load. These units can be plugged into a household wall plug on a dedicated circuit. Our 220v configuration is found on our two-post lifts or as an option on the Hemi Road Runner or RestoMod models, which will pull approximately 11.7 Amps under load. In most areas it is recommended that a qualified electrician hook up lifts with a 220v motor. It is important that all wiring meets local building codes. Not all motors are the same. The suggestions above are for US-made Butcher Hydraulic power units. Offshore units typically have a different load specification and pull upwards of 30AMPS.
