Yes, you can share the same white for neutral on both circuits, you must use a double pole breaker or two adjacent single pole breakers with a handle tie, and your wiring must be done such that removing a device doesn’t interrupt the neutral – in other words, pigtail the neutrals.
Can 2 separate circuits share a neutral?
What is a multiwire branch circuit? A multiwire branch circuit is a branch circuit with a shared neutral. This means there are two or more ungrounded (hot) phase or system conductors with a voltage between them and a shared neutral.
Can 2 circuits use the same neutral?
as long as the phase conductors are on different “phases” it’s fine. Recent code requires them to be on a double pole breaker though. I do it as much as possible in houses. It’s easier to pull one three wire for two circuits, than 2 separate two wires.
How many branch circuits can share a neutral?
one branch circuit
As you also mention, neutral conductors are not allowed for more than one branch circuit or one multiwire branch circuit or one set of ungrounded feeder conductors as stated in 200.4(A), unless specifically permitted elsewhere in this Code.
How many hot wires can share a neutral?
two hot wires
(Basically, two hot wires are sharing a neutral wire.)
Can two separate circuits share a ground wire?
So if your area has adopted NEC 2014, you can connect a grounding conductor to the grounding conductor from another branch circuit, as long as both circuits originate from the same panel.
Can you share a neutral wire NEC?
Sharing neutral or yoke
The NEC does not define multiple circuits. However, relating to 210.7, it appears to mean more than one circuit, on separate phases and each with its own neutral. If the circuits were on the same phase, simultaneous disconnection in the panelboard would not be possible.
What is a shared neutral breaker?
Quote from Youtube video: These two breakers must be on different phases. So each each breaker every other breaker is on is feeding from the left side and every other and then the up that one's from the right side.
How do you fix a shared neutral?
Quote from the video:
Quote from Youtube video: Then locate the shared neutrals in the electrical box and remove the wire connectors that splicing them all together then separate and identify each circuits to neutral conductors.
Can two AFCI breakers share a neutral?
Can the AFCI with shared neutral be used for retrofit installations? Yes, for retrofit installation, GE AFCIs can be substituted for the existing thermal magnetic breakers without the need to sort out existing shared or mixed neutrals.
Can two hot wires share the same neutral wire?
One neutral may not have two “hot” wires from the same phase. It is good practice to use four (4) pole Circuit breakers (as opposed to the standard three pole) where the fourth pole is the neutral phase, and is hence protected against over current on the neutral conductor.
Can two 20 amp circuits share a ground?
The code requires each branch circuit to have an equipment ground (either a wire, or conduit, or cable tray as in 250.120A), they can be shared when they are in the same raceway. If all the 20A circuits are in one raceway then you just need one ground.
Can two separate circuits be in the same junction box?
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.
Can 2 power supplies share a common ground?
If the two power supplies share a common ground, or can be made to, then it is no problem. However, the return wire must be sized for the sum of the 8 V and 12 V currents.
Can two power supplies be connected in parallel?
In general, yes you can parallel two supplies. How well this works depends on how well they end up sharing the load current. This depends largely on a good match in the output voltage of the supplies.
Can different voltages share a ground?
It is OK to use one ground with the voltage regulator circuit as you have shown. In fact, I don’t think it will work if the 12V source and regulator are referenced to separate grounds.
Can AC and DC share the same neutral?
You may want to tie AC ground (mains side) to DC ground (power supply output side), but it is NEVER a good idea to tie AC neutral to DC ground. This is a SERIOUS SAFETY ISSUE.
Can you ground AC and DC circuits to the same ground point?
Depending on the application, you can choose between a single ground point that ties all AC and DC voltages together, or separate grounds for the AC and DC voltages. In creating a common ground, you typically would connect the incoming AC voltage ground with the negative leg of the DC voltage.
What happens when an AC line touches a DC line?
If we connect an AC supply to the DC devices and equipment: The positive and negative voltage will destroy (this is not always the case) some of electronic components such as transistors and electrolytic capacitors. In case of higher AC voltage, they may burn with blast and catch fire.
