This is not strange at all. It’s because you have a feed in, two feeds out (going to other things on the circuit), and one switch loop. The switch loop is not using a “neutral” as a live. It is simply using a white conductor as a feed to the switch, or at least it should.
Why does my ceiling fan box have 4 wires?
In order for the light to be controlled by its own switch, the wiring between the switch and the fan unit needs a fourth wire, a red wire, to carry power to the light kit. Connect the green wire to the household ground wire (copper/bare wire). Connect your white wires together and secure with wire nut.
Why are there 4 electrical wires?
This configuration is used most often for large lighting arrays. Using one 240-volt line to power multiple 120-volt circuits reduces the amount of wire needed and the number of circuit breakers needed in the main power panel. A 4-wire circuit will have a red wire, black wire, white wire and a ground wire.
How many 12 gauge wires are in a junction box?
Capacities for two common sizes: Single Gang Boxes: A total capacity of 18 cubic inches allows for nine #14 gauge wires, eight #12 gauge wires, or seven #10 gauge wires. This is a wires-only capacity.
Why is there 4 wires in my light switch?
Since the switch cuts the power on and off, there will be a black wire coming into the switch and a black wire leaving. The whites are normally just connected together with a wire nut and the coppers are connected together with a wire nut or grounded to a metal junction box. So the new switch has four wires.
What is a 12/4 wire used for?
Non-metallic sheathed NM-B cable is used in normally dry installations in residential wiring, as branch circuits for outlets, lighting and other residential loads.
12/4 NM-B Cable Specifications*:
| Cable Type | NM-B |
|---|---|
| Direct Burial | No |
What is a 4 wire electrical system?
A four-wire delta (4WD) electrical service is a three-phase delta service with a center-tap on one of the transformer windings to create a neutral for single-phase loads. Motors loads are commonly connected to phases A, B, and C, while single-phase loads are connected to either phase A or C and to neutral.
How do you connect 4 wires to a junction box?
Quote from the video:
Quote from Youtube video: Just run at all cut the zip ties off to you. And then for a little 4 wire connection I like to use the red marette. Just put it on twist. It.
What is a 4 wire switch?
It has four wires coming out of the back. For Single-Pole Wiring (a single switch controls the light or outlet) it’s easy: The A wire (black) connects to the hot (black) wire from the power source. The B wire (blue) connects to the other wire from the load. The C wire (red) is not used and is capped with a wire nut.
How do you wire a switch with 4 terminals?
Quote from the video:
Quote from Youtube video: A few of them together. And we're going to be ready to go.
What does a 4-way switch look like?
Quote from the video:
Quote from Youtube video: You will notice that this switch has four terminals not counting the ground. The other two switches on the left and the right are three ways notice that these two switches.
What is a 4-way?
4-way or Fourway can refer to: an acoustic system containing four loudspeakers. a formation skydiving event, “4-way sequential”, that has four members in each team.
How does 4-way switch work?
There are four terminals that provide two sets of toggle positions on a 4-way switch. Each set of terminals is one of the toggle positions. When the switch is in the up position, the current can flow through two terminals. In the down position, the current flows through the other two terminals.
How do you tell the difference between a 3 way and 4 way switch?
A three-way switch has three terminals; a four-way has four. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances.
Which switch is having four terminals?
A DPST switch has four terminals: two inputs and two outputs. The most common use for a DPST switch is to control a 240-volt appliance, where both supply lines must be switched, while the neutral wire may be permanently connected.
How can you tell which wire is common on a 4 way switch?
Quote from the video:
Quote from Youtube video: This group of wires goes to the upstairs switch in this group that's connected to the switch still goes downstairs. As you can see that's the hot set of wires this is just a little voltage tester.
How do you wire a 4 wire light fixture?
Quote from the video:
Quote from Youtube video: Up back to the last three-way switch the black and red wire coming out of this three wire cable are gonna hook to the brass screws on this switch.
Is a double pole switch the same as a 4-way switch?
Double pole light switches, also known as a four-way switch, are two single pole switches put together. Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit.
