110 Volt vs 220 Volt (identical to 120 Volt vs 240 Volt)


(Straight = Hot, L-shape = Neutral, Round = Ground) Appliances with 110 volt that pull more than 15 amps demand a 30 outlet that is amp 10 measure cable and a Nema 5-30 plug. A regular 3-prong cord is used if 110-120 volt appliance is under 15 amps.

(Hot is actually the verticle and right) Appliances with 240 volts demand a 20 amp socket with 12 measure cable and a Nema 6-20 plug.

Pictured left to right: Heavy duty 30 amp 110-120 volt Nema 5-30 Plug, Standard 20 amp 220-240 volt Nema 6-20 Plug, and a typical 110 volt plug as entirely on many electronic devices.


What’s the distinction between 110/120 and 220/240 volts and it is one better. Browse below for responses. NOTE: often 120 volts is called 110 volts or 115 volts and 240 volts as 220 volts or 230 volts.

Would be the engines exactly the same into the 220-240 and 110-120 variations of vacuums? No, the motors are wound differently, the transformer is significantly diffent, the minibreakers are very different, additionally the wiring and cord are very different.

Can an appliance be utilized on SLIGHTLY pretty much voltage? Being a main vacuum cleaner manufacturer we make use of the 120 and 240 volt engines. The 120 and 240 engines won’t be adversely impacted if combined with reduced voltages. The 120 volt engine will be fine on a 110 volts. And a 240 volt motor will be fine on 220 or 230 volts. Although not one other means around. A 220 volt motor would be “damaged” if used for very long amounts of time for a 240 volt circuit. Therefore the exact exact same for the 110 motor that is volt on 120 volts. The motors we utilize will even run fine in every variation of 50-60Hz.

Is certainly one better? For the part that is most, our engine maker has virtually identical performance data between your voltages. Our 120 volt Silent Master S900, for example has 139 waterlift and 191 CFM with a peak of 905 Air Watts. The 240 volt version has 136.4 waterlift and 190 CFM by having a top of 866 Air Watts. These stats are really close. But there is quite an improvement within our Silent Master S500. The 120 volt has 85 waterlift and 183 CFM by having a top of 514 Air Watts. It’s 240 volt counterpart has 95 Waterlift and 208 CFM having a top of 722 Air Watts. That is actually a factor. For many domiciles, maximum amperage with regards to their panel might be close so that the 240 volt variation supplies the most readily useful advantages.

Running Price. The price to use a 240 volt cleaner can come to be not as much as its 120 volt counterpart because both stages associated with energy are now being used simultaneously. But perhaps the 120 volt variation may possibly not be wasting much energy if the opposing circuit will be utilized by lights or any other appliances during the exact same time. Worst situation situation, the 120 volt variation could cost a few cents per hour extra to operate.

Duration of Life. We think the 120 volt variations regarding the cleaner engine shall go longer. They have a greater number of copper and so the warmth has a larger capability to dissipate.

What the results are whenever 240 volt is accidently attached to 110 volt? And 110 into 240? It will spin at nearly twice its normal RPM if you plug a 120 volt unit into a 240 volt circuit and turn the vacuum on. Or even straight away switched off the engines may disintigrate, but before that takes place, the transformer will likely burn up. Typically everything you need to do is change the transformer therefore the system is likely to be just like brand brand new.

It will not run correctly if you plug a 240 volt unit into 120 volts. Very good news could be the transformer or motor(s) will never be harmed. You will simply be operating it on half speed. In reality, this is actually the method you are able to “break-in” new engine brushes when they’re changed away down the road. (Run the system in at half rate.) Additionally observe that the transformer shall maybe maybe not trigger the relay unless this has 240 volts.
