Voltage, Phase & Amperage

electrical specs: Electric equipment lists voltage (120/208/240V), phase (single or three-phase), and amperage (the current it draws). Together they define the circuit and receptacle it needs. Getting them wrong means the unit can't be installed — or trips breakers.

Why it matters when buying

High-output electric cooking and warewashing often need 208/240V three-phase power that many kitchens lack, so verify your panel before you buy. Amperage sets the breaker and wire size; the plug type (NEMA configuration) must match the receptacle you'll install it on.

How to read it on a spec sheet

Match voltage, phase, amperage, and the NEMA plug/receptacle to your electrical service. For three-phase, remember amps × volts × 1.732 gives the power. When in doubt, have an electrician confirm the circuit before ordering.
