How do you wire two switches from the same power source?

If you’ve mounted two switches in the same electrical box, prepare two black wires. Connect one end of the 6-inch wire to the top terminal of the first switch. Twist the other end together with the black wire from the incoming circuit cable and the black wire from the cable going to the second switch to form a pigtail.

Can two different circuits share a 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).

How do you separate light switches?

  1. Get a 2-gang box to replace your existing 1-gang box.
  2. Get a new switch.
  3. Remove your existing box and install the 2-gang box in its place.
  4. Run your supply hot wire to both switches.
  5. Connect the light/fan hot wire to one switch and the exterior light to the other.
  6. Join all neutrals and ground wires.

Can I use the same neutral wire for two circuits?

If the two circuits are from the same line, the main danger is overloading the neutral with too much current. A fire hazard as the neutral is not connected to a breaker. In short, stay safe and run separate neutrals for each circuit. you definitely do not want to share neutrals from different circuits.

How many wires are needed between 3 way switches?

With a three-way switch, three wires connect the pair of switches—two black “traveler” wires and a third “common” wire. When the circuit’s power is turned on, any of these may be “hot,” depending upon how the switches are toggled.

Can you split electrical wire?

You can split receptacles to achieve the same effect. Run three-wire cable from the service panel to the boxes for the two circuits. When wiring a series of split-circuit receptacles, connect one outlet of each receptacle to the red wire and the other to the black wire. Be sure to break off the brass connecting tabs.

Can I share a neutral on 3 circuits?

In short, stay safe and run separate neutrals for each circuit. you definitely do not want to share neutrals from different circuits. This sets up a potential shock hazard if one circuit breaker is open and the other closed.
