120V or 240V ǀ All you need to know about Electrical Wiring

Kind of like the water flow rate through a pipe. Power = Volts X Amps. A higher voltage requires fewer amps to deliver the same power, as these two simple equations will illustrate: 1000W = 120V X 8.3A OR 1000W = 240V X 4.17A. If we supply double the voltage, for the same watts, we will be drawing half the amperage.

208 vs. 240 Volt

Some equipment may call for 240 volts. When many of us see a specification for 208 volts, it gets confusing. What is the difference between 208-volt and 240-volt? 240-volt is single-phase power, while 208-volt is 3-phase power. Phase refers to the method of delivery of the power load. 3 phase requires 3 wires.
