# What does 208Y 120V mean?

## What does 208Y 120V mean?

In the USA the most common configuration is 208Y/120. This indicates that line to line (L-L) voltage is 208Vac in a WYE configuration and the line to neutral (L-N) voltage is 120Vac.

### Is 208V the same as 120?

208V is the voltage between phases of a 3-phase “Y” circuit that is 120V from neutral to any hot. 480V is the voltage between phases of a 3-phase “Y” circuit that’s 277V from hot to neutral.

#### How does a 120 208 panel work?

For example, on a 120/208 three-phase system, which is common in North America, the phase-to-neutral voltage is 120 volts and the phase-to-phase voltage is 208 volts. This allows single-phase lighting to be connected phase-to-neutral. This eliminates the need of a separate single phase transformer.

What is the difference between 120 240V and 120 208V?

120/240V is a 240V single phase supply, center tapped to produce a “split phase” with 120V between either side to neutral, and 240V between the two hot lines. 120/208V is two phases from a three-phase supply. There is 120V from either phase to neutral, and 208V between the phases. Apartments have 120/240v service.

How do you get 120V from 208V 3 phase?

Locate and identify the ground or neutral terminal of the 208-volt 3-phase system. Connect the input terminals of your circuit between any phase conductor and the neutral terminal of the system. This connection point will deliver 120-volts to your circuit.

## Can a 208 be 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.

### How can I get 120 out of 208?

#### Can I use 208V on 120V?

Do not plug it into a standard 120V house circuit. 208 usually denotes a voltage available in commercial buildings with three phase service.

What is the phase colors for 120 208?

In commercial 120/208-volt medium voltage and 277/480-volt high voltage electrical systems, there are three phases – A, B, and C. Each phase is one of three colors – black, red, or blue for low and medium voltage and Brown, Orange, Yellow for high Voltage.

How can I get 120V from 208?

## Is the 120 208 panel the same as 240?

The most common commercial building electric service in North America is 120/208 volt wye, which is used to power 120 volt plug loads, lighting, and smaller HVAC systems. In larger facilities the voltage is 277/480 volt and used to power single phase 277 volt lighting and larger HVAC loads. Click to see full answer. Herein, is 208 the same as 240?

### What does ” 120 / 208 ” volts mean in electrical category?

Appliances and equipment rated for 120/240 volts may be used on a system that measures 110/220 volts. Appliances and equipment rated for 120/208 volts but not 120/240 volts may generally not be used on a 120/240 volt system or on a system that measures 110/220 volts. (Some analysis would need to be done to see if a particular item would work.)

#### Where does 208 volts 3 phase come from?

The power is brought is as 208 volts 3 Phase and then the Line-to-Neutral Voltage will be 120 Volts. Each of the three Line-to-Neutral line will go to a part of the plant.

Are there any 120 / 208 volts in the op?

The OP may have a 120/208V appliance only, but that is rare in the USA. The spec sheet (follow the link in that ebay listing, or here: http://www.primebusinesssurplus.info/images/CBS-2032s.pdf) does give a range of electrical configurations, including 120/208, 120/220, and 120/240.
