# Quick Answer: Do you need a neutral for 208V single phase?

Contents

## Does 208V use 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). Each leg (phase) provides power (phase voltage) at a unique angle (phase angle) to the center (neutral).

## Does single phase need neutral?

Single-phase power supplies have a neutral wire as well. Both single-phase and three-phase power distribution systems have roles for which they are well-suited. But the two types of systems are quite different from each other.

## Can you have 208V single phase?

120/208V single phase is derived from 208V three phase power. … When using 120/208V single phase, you will use any two of those same three hot conductors, with the two waveforms peaking 120 degrees apart from each other.

## What is 208 voltage used for?

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.

## 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.

## What is the use of neutral wire in single phase?

Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.

## What is the purpose of neutral wire in single phase?

The line drawn from the neutral point of transformer is called null line, or neutral wire, whose main function is to connect single-phase load, transmit single-phase current and three-phase unbalanced current, and reduce the neutral point potential drift of load.

## Is 208V the same as 220V?

In North America, the terms 220V, 230V, and 240V all refer to the same system voltage level. However, 208V refers to a different system voltage level. … With electrical loads, the voltage will drop, hence the common reference to voltages below 120 and 240, such as 110, 115, 220, and 230.

## Can I plug a 208V into 120V?

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