Can I use a neutral from another circuit?
If you use a neutral from a different circuit and it happens to be on a different phase you run the risk of heating the conductor and causing a fire.
The problem occurs when it is on the same phase, not a different one.
Still shouldn’t be done..
What is a shared neutral in electrical terms?
(HawleyHomeInspectionsLLC.com) So often we find something we have done a certain way for years is suddenly no longer considered proper. This is where we are today with what is called a shared neutral. … We would share the neutral (white wire) and the ground wire (bare or green wire).
What wire do I use for neutral?
white wireThe white wire is the “neutral” wire, which takes any unused electricity and current and sends them back to the breaker panel. The plain (or it can sometimes be green) wire is the “ground” wire, which will take electricity back to the breaker panel, then outside to a rod that’s buried in the ground.
Can you connect neutral to hot?
When you put a load (a light, a vacuum, a range hood) between the hot and the neutral, power flows. This is parallel wiring. You can have multiple separate loads between the hot and the neutral. … There is never a direct connection between the hot and the neutral wires.
Why are neutral wires tied together?
The neutrals were all tied together to make one group so it doesnt matter which one makes it to the switch.
Can two separate circuits be in the same junction box?
2 Answers. The answer is yes you can have 2 separate circuits in the same box (they can have a splice also but not needed in your case). The only concern would be the total box fill. Based on the NEC the wire fill would be calculated at 2.0 for each conductor for 14 gauge wire and 2.25 for 12 gauge wire.
How many circuits can a neutral share?
You can only have one neutral per circuit in a single phase system, it is a current carrying conductor. If you use one neutral with two circuits you can exceed the capacity of the conductor and damage the conductor.
Can two switches share a neutral?
You CANNOT tie two separate circuit breaker neutrals together unless it’s a double-pole breaker that supplied opposite line phases. if of one of circuit neutral is loose. … GFCI/AFCI plugs will detect an imbalance on the current that’s passing via the neutral and hot and will trip.
What is a borrowed neutral?
May help some of the learners … like it did me. The most likely instance where you will find a borrowed neutral is the hall/landing light circuit with a two way switch which enables you to switch on the light from the bottom or top of the staircase.
Can you share a neutral with multiple circuits?
It is NOT permitted to share a neutral in any other situation. If you were to share a neutral with two breakers on the same leg of a panel, both circuits could draw the breaker limit (lets say 15A) making the shared neutral as much as 30A return current!
Can 3 circuits share a neutral?
If you have an electrician servicing your electrical equipment, make sure you provide instructions in your work order where common neutrals exist. As an electrician, you can suspect a multi-wire branch circuit when three or more neutral conductors are spliced together in a junction box, outlet box, or lighting fixture.
