Does 230 volt need a neutral?
Tips on 230-Volt Wiring
If the circuit is dedicated to an appliance that does not need auxiliary 115-volt power, the neutral can be eliminated. In that case, the cable would include only the two hot wires and the ground. 230 volt wiring requires 10-gauge or larger wire which, because of its size, is hard to bend.
Do you always need a neutral wire?
The presence of a neutral wire is not required (many computers do not have a neutral wire connection). Grounding problems only exist in computer installations when two separate pieces of grounded equipment are interconnected through data communication lines.
Does 208V single phase exist?
120/208V Single Phase Power
120/208V single phase is derived from 208V three phase power. If viewed on an oscilloscope, the three voltage waveforms on the three “hot” conductors all peak at different times: each one is 120 degrees behind the next.
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.
Does a 220 circuit have a neutral?
220 doesn’t ‘need’ neutral because each pulse uses the off phase of the other side for this purpose and AC back and forth but where is the circuit since the power is only looping back to the hot bars.
Will an outlet work without a neutral?
If there’s an open neutral, the outlets won’t work, but they will still be energized. Use a plug-in circuit tester to check for an open hot or open neutral. … An outlet or light switch with an open ground will still function, but because it lacks a safe path to earth, that device could give you a shock.
