110V Vs 120V Difference. 120v is the ac voltage on a single hot wire in your home with respect to neutral. You'll often hear voltages in your home referred to as 110v, 115v, or 120v. Is there still a 110v supply anywhere in the usa ?
The real difference is you can put a junk extension cord on a 110v pump causing it to pull more amps and run hotter, at 220v it's hardwired with the proper sized wire at the if the mains supply wire is sized appropriately, the current going through the winding's is exactly the same wired for 240v vs 120v.
110v is normal electricity you get from your average wall plug. So if volts x amps = watts, who cares what the voltage is? You'll often hear voltages in your home referred to as 110v, 115v, or 120v. As long as the result is the same, i pay for kwh, not amps. The real difference is you can put a junk extension cord on a 110v pump causing it to pull more amps and run hotter, at 220v it's hardwired with the proper sized wire at the if the mains supply wire is sized appropriately, the current going through the winding's is exactly the same wired for 240v vs 120v. Or is it all now 120v ? For most things, this may not cause an issue as the voltage (potential difference across) is still 110v. This can be confusing but the bottom line is they are referring to the exact same thing.
