What's the difference between 220 volts, 230 volts, 240 volts? Will my equipment work?

I describe the difference between 220 volts, 230 volts and 240 volts. Many people wonder if their equipment will work with a different voltage. I explain how to determine what voltage you actually need by determining whta the manufacturer specifies.

This just saved me $300. Thanks for the great explanation.

Easy to understand. Thank you for the knowledge.

I dont know about other places, but here in Texas, 125/250 volt is in common use. Just tested a panel yesterday with 252 volts

Useful video! I just bought a 230v Fender Tube Amp, but here in Malaysia the voltage is 240v. I'm notice it runs hot, could that be to do with the extra 10v or is it nothing to worry about?

well explained the best i have seen 5*

Actually not always. I bought some old equipmentand it blowed quickly just because they were rated 220V and the mains is 240V. One, an old Philips amplifier stopped working after one week, its preamp had Zenner 5W diodes that burned when used at 240V; another, an old HP lab power source also rated 220V instantly burned some opamps in the regulation part because the applied voltage was higher than max rating for them. An tube (valve) radio, just recapped, burned one tube filament after few weeks of use because instead 6.3V it had 7V at filaments. Many old power adapters with transformers ran hotter when used at 240V.
All aplliances that gave problems (burning, running hotter) were powered through transformers.
So, not, an 10% variation for the mains can actually destroy your equipment.

unless it's EU and all them where it's 230v 1ph where it's 230v on line and a neutral at 50hz then hooking it to 240v american 60hz as per say a motor it will hook up just run 20 percent faster depending on motor. most other appliances or gadgets etc always check the plate ratings for that.

Hi there I would like to ask you a question I am buying a amplifier from overseas in Spain and he says it runs at 220 volt and l am in Australia at 240 volt do I need to just change the cord or is there more involved
Thanks David 😮

Will a 240 volt air conditioner from England work on our 240 the one in England is 240 phase to ground and ours is 240 phase to face will it still work

[juanpapa]

I have a ac unit that is 220v but I'm only getting 214 from the power supply can that cause the ac not to cool

[wassermeister]

bought a tube 230 volts amp, 50 wats, not sure if here its 110 or 120 v, will I cause a fire?

[luizguilhermewasthnerdelim]

Can we use a laptop cable(145 watts) with a 240v battery fit in a 220v?

[NLIFE]

Ive got a psu 230v but our cpuntry only have 220v output is it possible work

[trevorbraden]

Now would all of that be on a double breaker

[YounisMengal-vlogs]

Sir can we use just phase and earth and voltage is 245 to 240. Is it safe for home electronics??

[ayeshaakhtar]

i have brought a 230V hair dryer but my country's average voltage is 220V, will that be a problem?

[mr.s]

I have a question is voltage supposed to surge to 320v ? It’s supposed to be 220v and it is but is goes up to 320 and back down and back up and it does it constantly?

[marktheunitedstatescitezen]

Can I split a Chinese grade 230v 1 phase into 2 lines of 115v 1 phase ?

[fahimbaksh]

My coffee machine the voltage mentioned 220-240V 59-60 Hz ( 2.8 - 3.3 KW ).
Can I plug into 220V. Will it be safe and will it work please.??

220v vs 110v size of appliance at same Wattage ? ( amount of copper in motor )
