Basic electrical calculations involve three parameters, volts, amps and watts. Volts Here in the United States, we design according to specific voltages provided by our utility companies. In residential construction, we often have 120/240V, single phase, 3-wire, while in commercial construction we typically have 120/208V, 3 phase, 4-wire or 277/480V, 3 phase, 4-wire (although older […]
