Is neutral wire same size as hot in 200 amp panel?
Yes, in a residential 200 amp panel, the neutral wire is typically the same size as the hot wires. This is to ensure that the neutral wire can safely carry the same current as the hot wires and maintain proper balance in the electrical system. Always consult the National Electrical Code or a qualified electrician for specific requirements.
What size wire for neutral in a 240v 30 amp circuit?
Answer for USA, Canada and countries running a 60 Hz supply service.240 volt two wire circuits loads do not need a neutral to operate. A three wire 240 volt circuit that needs a neutral, will have a neutral the same size as the current carrying conductors. In this case a #10.
Does the neutral wire size and the hot wire size have to be the same on a 120v 208v bank?
If the load is perfectly planned AND purely resistive the neutral current would be zero in a 3-phase 4 wire circuit. But that is extremely rare. Before nonlinear loads (fluorescent lighting, computers, dimmers, variable speed drives etc) 1/2 size neutrals were often used but now full size neutrals are used to cope with the increasing levels of 3rd harmonics resulting from modern equipment, which can lead to neutral currents approaching or even exceeding the phase current. With very high levels or harmonics, double size neutrals are being used in places
What color is neutral wire in Australia?
The colour of the neutral wire in Australia is blue with marking N.
Which is the Hot wire and which is the Neutral wire if the wires you see are a Brown a Blue and a Yellow Green wire?
In electrical wiring, the live or "hot" wire is typically brown or red, the neutral wire is typically blue or black, and the ground wire is yellow or green. So, in this case, the brown wire is likely the hot wire, the blue wire is the neutral wire, and the yellow green wire is the ground wire.
When upsizing wire for voltage drop how much smaller can the neutral wire be the next phase conductor?
The neutral wire should be the same size as your conducters
What wire size for 400 amp service neutral size?
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.

What is a floating neutral wire?
a loose connection of a neutral wire
Why you take radius or size of neutral wire half wrt phase conductor?
On three phase services over 200 amps the electrical code allows the electrical contractor to reduce the size of the neutral wire . This saves the customer money. There are conditions as to how much the neutral can be reduced but it is not as low as half the supply conductors. The reason that the neutral can be reduced is that it only carries the unbalanced current on the three phase four wire system.
What size neutral wire for 200 amp service panel?
AWG # 3/0 copper.
Does the neutral wire size and the hot wire size have to be the same on a 120v 208v bank?

Why can the neutral wire diameter be reduced in relationship to the phase wires?
The Neutral wire should be the same gauge and size of the phase wires. Only the Earth or Equipment wire can be smaller than the phase(hot) wires. <<>> On a three phase four wire distribution system the neutral can be reduced in size. The neutral only carries the unbalanced load current and should be sized to that current. The highest current load to neutral of the three legs is used to calculate the neutral sizing. There is no reduced neutral allowed on discharge lighting and non linear loads. A demand factor of 70% shall be permitted to be applied to that portion of the unbalanced load in excess of 200 A.
What does an open neutral mean?
Typical home wiring will have one hot wire, one neutral wire, and one ground wire per circuit. An open neutral would indicate that the neutral wire, usually white wire, is broken.
Is the ridged wire neutral or hot?
If wired properly the ridged wire is the neutral.
What color is the neutral wire?
The neutral wire is typically colored white or gray.
