Does all romex have a ground wire?
Some older wire does not have a ground. All you can do in that case is use a jumper wire to connect the ground to the neutral.
Why no electric shock from neutral line?
There is normally no voltage on the neutral line because the neutral line is grounded. However, and this is always important, do not assume that neutral is grounded, nor that there is not an elevated voltage on neutral or ground due to a possible ground fault.
Does a toaster use a neutral phase?
There is no such thing as a 'neutral phase'. 'Live' or 'hot' conductors are called 'lines', whereas the neutralconductor is at approximately earth (ground) potential.So, a toaster would be connected between a line and a neutral conductor.
What is meant by neutral grounding reactor?
Neutral-earthing reactors or Neutral grounding reactors are connected between the neutral of a power system and earth to limit the line-to-earth current to a desired value under system earth fault conditions.
How do I rewire an ungrounded plug?
If there is no ground wire connect the ground wire to the neutral wire.
Does all romex have a ground wire?
Some older wire does not have a ground. All you can do in that case is use a jumper wire to connect the ground to the neutral.
Can you use ohm-meter to measure a resistance between the neutral line N and the ground E?
If the meter is sensitive enough and there is a resistance between the neutral and ground then the meter should be able to detect it.
Can you use the earth wire between room stat and honeywell board as a neutral?
ABSOLUTELY NOT!The protective earth ground wire is only there to provide a low resistance path to ground in the event of a short circuit so as to trip the protective device. Operational current is never, under any circumstances allowed to be passed on earth ground. Use neutral for neutral and ground for ground.CONSULT A QUALIFIED AND LICENSED ELECTRICIAN !!!!
What is the reading ground to neutral?
Ideally ground and neutral should be at the same potential, but as there is current in the neutral wire and no current (normally) in the ground wire there can be a difference. I have personally measured over 25 VAC on the neutral relative to ground in some systems.
Single phase 4 pole Gen alt w 240V 60hz output no neutral. you check from each lead to ground and get 50-70V How do you get a neutral for connecting Gen to a standard breaker box having 240V and 120V?
Neutral is at the jumper that changes it from 120v to 240v. Two stator windings are used in series to make 240v; at that junction is (when wired in Series)your neutral/common/ground. Ground this terminal and use it for your neutral/common. When wired in parallel you have 110v and the jumper is removed and there is no common/neutral and ground is from the frame of the generator.
Why you use neutral pin in three pin plug?
In North America the neutral pin is used to complete the circuit. One pin is "hot", one pin is neutral and the last pin is ground.
Is it advisable to use line to neutral power supply on a single phase residential area when the safety is concern?
line to line or line to neutral is the only way to use power line to ground if a FAULT current in the ground is a problem that needs to be corrected, an insulation fault
Difference between ground and neutral?
As i know,neutral is the return path of current & ground is for any leakage current
Why do some electric panel have ground and neutral bonded together?
By National Electric Code only the Main Panel should bond ground and neutral. If subpanels have ground and neutral bonded, it could cause ground loops and shock hazards.
Converting a pump motor from 110 to 220v 2 hot leads and a ground is there any use for the neutral?
we dont need a neutral because we had a 2 hot leads
Can a green wire be used for a neutral?
'Can' yes. 'Should' no. <<>> Never use a green wire for a neutral. It is colour coded for a reason and that is to protect the people that work on electrical equipment. If you turn a ground wire into a neutral it then becomes a current carrying conductor. There are times in the electrical trade when grounds have to be disconnected and if it is used as a neutral and the tradesman is holding one end and touching a grounded object a shock will occur. Again never use a green ground wire as a neutral.
Why does your panel have a neutral but no ground?
Just checked and it does have a ground connection.
