# Is 208 volts and 220 volts the same?

## Is 208 volts and 220 volts the same?

“220” is what the unqualified use to describe 240 volt circuits. 208 can only be obtained from a 3-phase wye system.

## Can 220V equipment run on 208V?

Most devices designed for 220 will run on 208 and in shops all over the place this is commonly done. Purely resistive components (like heaters) will run at a slightly lower power. So, your machine will work, but will take longer to come up to temperature.

Can I use 208V instead of 240V?

208V is *not* the same as 240V. 208V is the voltage between phases of a 3-phase “Y” circuit that is 120V from neutral to any hot.

### Whats the difference between 208V and 240V?

They require two legs of power from the power utility, whereas 240v motors and appliances only use one. You will commonly see 208v present in three-phase buildings when “single-phase” equipment (like an A/C condenser) is wired to two legs of three-phase wye power.

### Does 208 have a neutral?

208 volts is Line-to-Line Voltage. This three Phase voltage is frequently used in small businesses. It is 208 volts /1.732 which is 120 volts. The power is brought is as 208 volts 3 Phase and then the Line-to-Neutral Voltage will be 120 Volts.

What is 208 voltage used for?

The voltage is used in larger facilities to power single phase lighting and larger heating, ventilating, and air conditioning loads.

## Can a 240 volt motor run on 220?

The 220v only has 2 wires. The plugs are configured differently to avoid hooking up the wrong power because the motor must be designed to match the power supply. A 220v motor won’t deliver as much Torque.

## Is 208V single or 3 phase?

What is 208v used for? The 208V is a result of requiring a phase voltage of 120V on a three phase system for things such as receptacles. In three phase, the phases are 120° apart from one another. When you convert phase voltage of a three phase system to a line voltage, you have to account for this 120° difference.

Does 208 3 phase have a neutral?

208V 3 Phase power has 3 electrical legs (phases) evenly spaced in a circle (360 degrees / 3 phases = 120 degrees) around a center (neutral). 208V 3 Phase power also goes by the names 208V 3 Phase 4 Wire and 208Y/120V. These are technically more accurate because they refer to the neutral.

### Does 208 230 need a neutral?

Since the label says single-phase 208/230 it means it requires two hots legs and NO neutral. A 3-phase A/C unit rated @ 230v would only require 3 conductors and a ground.

As the voltage goes down, the amperage rises, which could affect wire size and over-current rating. 208 volts is used to obtain the common voltage of 120 volts for receptacles and lights. The previously described three-phase systems are the most common ones that home inspectors will encounter.

### What is the difference between 208 and 240?

“220” and “240” are the same thing. “220” is what the unqualified use to describe 240 volt circuits. 208 can only be obtained from a 3-phase wye system. 240 volts can be obtained from either a 120/240 residential system or a 240 volt 3-phase delta system.

What is 208 volt single phase?

Thirdly, 208 volts can be used in a double pole, single phase circuit where the voltage potential is 208 volt between phases, or in a 3 pole, 3-phase circuit with 208 volts between each phase. Each of these phases wether it be a single phase or three phase all have 120 volts each to ground.

## What is 208 single phase?

In the USA, 208V single phase and three phase voltage is one of the standard voltage levels used for commercial applications. It can be derived from Wye-Wye (Star to Star), Delta-Wye or High leg delta configuration of primary and secondary windings of the transformer.
