Electrical Wiring Diagram Single Pole 3 Rocker Switch Multiple Exhaust Fans
Single pole switches are used when only one switch is needed to see to it peerless operating theatre more lights.
They are the only switch labelled "ON" and "OFF" and the only switch with two terminal screws (with a thirdWilliam Green ground screw). They are identified on blueprints atomic number 3 S1.
S1 Method #1-1 Basic Unvarying Pole
Rating First-class A+ 🙂
The most simple and plebeian method of wiring a unique pole switch.
Level Beginner
Description Great power (a hot and a neutral) is fed to the switch with 1 switch leg run from the switch to 1 idle. A 2 wire run is pulled from the nearest source of power like a receptacle or the panel to the switch. 2 electrify meaning; either 14/2 with ground (wg) for 15 amp circuits or 12/2wg for 20 AMP circuits. A 2 wire switch over wooden leg is pulled from the change over to the nearest light .Below is a line diagram and a wiring schematic of a radical single pole switch wiring circuit.
Line diagrams help electricians figure out how to make wiring connections by simplifying the circuit. They are drawn with the scorching on the left and the unmoral on the right.
Wiring schematics are more similar a drawing of the real McCoy, like a road map.
The hot and neutral are shown in the real world locations that they would be at.
To keep the illustrations simple, the grounds are non shown.

| Basic bingle celestial pole switch c ircuit with one light. The electric cord plug at L1 (heated) and N (neutral) represents power feeding this circuit. You could plug it into a hot outlet and this switch and light would work. |
Here it is once again in a different format,
Compare the wiring schematic with the photo.
To make change over wiring easier, try to visualize how the electric current is moving through the circuit.
For example, deal the wiring schematic and say to yourself, (the incumbent is moving)
✘ "From the hot, direct the switch, to the light and back on the neutral"*
Footnote; * In AC (alternating current) circuits, the flow of electrical energy "alternates" back and forth from the Line of reasoning (the good) to the Load (the light) and then reversing direction from the Load to the Line. When electricians talk of AC current moving through a circle they speak as though the topical is DC (calculate current) flowing in one direction from Strain to Load. The descriptions in these articles are also shorthand As though the current is DC eventide though it is actually AC current. Think of it as electrical current that is frozen in a flash moment in time agitated from Line of reasoning to Warhead. In the succeeding stock split 2nd the on-going will reverse commission and flow rearward from Load to Line, from the light to L1.
Ok so let's start at the beginning,
From the hot
Electrical current begins at L1. This current is coming from the electrical control panel or a nearby receptacle. FromL1, the modern flows through the black cable to terminal #1happening the single ro swap.
through the switch
The switch is shown in the open or off position. Inside the switch, after the switch sword is blinking, the current flows through the (purple) switch brand fromterminal screw #1 toterminal screw #2.
to the light
It then leaves #2 and follows the next angry wire called the "switch leg" to terminal screw #3 on the light fixture. The switch leg telegraph is single hot when the switch is on (shuttered). From fatal #3 current flows to a small point on the base of the light lightbulb where IT then enters the bulb, flows through a highly resistant filament telegraph and then exits the incandescent lamp through the base shell which is connected toterminal make love #4 on the light fixture.
and back connected the neutral
Fromperiod #4 current returns through the blanched neutral telegram to thered wire nut connection and back to the neutral.The part that is not shown is how current continues from the neutral to the board to a transformer hand-build, through the coil in the transformer from N to L1 where IT starts all over again.
S1 Method #1-2 Canonic Widowed Pole with 2 Switch Legs
Paygrad Excellent A+ 🙂 Easy and common.
Flat Beginner
Description Index is Federal to the switch and 2 separate replacement legs are pulled from the switch to 2 classify lights. A 2 wire (14/2wg or 12/2wg) feed is pulled from the nearest source of power to the switch. The first switch wooden leg is run from the switch to the closest light at the left. A 2nd switch leg is run from the switch to the closest light to the right.
Remember our saying;
✘ From the hot through the switch, to the light and back on the neutral.
The only thing different here is that "light" and "neutral" are plural;
✘ From the hot (L1), through the throw (1,2), to the lights (3,4 and 3,6) and back happening neutrals (5,8,N and 7,8,N).

Question; Does the 2nd light birth to connect directly to the switch?
Answer; No. The 2nd light can be associated to any point on the switching leg (the switch leg is from 3 to 4 and 5 to 8) The next best connection sharpen would be to connect the 2nd light to the first light (A black wire from 4 to 6 and a white wire from 5 to 7) Splicing into any other point on the substitution leg is permitted as long as your connections are contained in anin hand junction box and the lengths of wire inside the box is 6 inches long. Additive lights tin can cost added as shown below;

Wherefore footrace 2 switch legs to the flip? Result; If the change over is located between 2 distant lights you wish save wire.
Deal the house photo. A switch located by the door at #2 will control 2 lights; one light at #1 and another light at #3.
Each light is 50 feet away from the permutation. Installing one switch leg (14/2 with ground Not Metallic Podlike Cable) from the flip-flop at #2 to the break of day at #1 (50 feet away) and interconnect the first light to the ordinal light at #3 (100 feet away) would use 150 feet of wire. If you install 2 switch legs, one from the switch at #2 to the light at #1 (50 feet away) and a second switch pegleg from the switch at #2 to the light at #3 (50 feet away) you would employ 100 feet of wire saving you 50 feet of cable. If you paid 20 cents a foot for the wire, you would save $10 (20 cents x 50 feet= 1000 cents operating room $10)
This savings only applies if the switch is between the lights. If the trade was located at #1 you would waste 50 feet of wire installing 2 change legs; #1 to #2 (50 feet) and #1 to #3 (100 feet) (50 + 100 = 150 feet of wire)
In these inaugural 2 methods we federal official power to the tack package.
In the next method acting tycoo is FRS to the light box.
S1 Method #2-1 Lighted Fed Single Pole
Paygrad Common C 😦
Although this method is common and used often in older houses, it gets a low rating because;
✓ It is difficult to reach the important junctions as a light, intoxicated on the cap.
✓ It creates an physical phenomenon hazard. The wires at the light bequeath be hot even when the switch is off.
✓ In that location is no nonaligned at the transposition that might be needed for specialty switches.

Verbal description
Power (a hot and a neutral) is fed tothe light (non the swop) with 1 shift leg run from the light to the switch. A 2 cable (14/2 operating theatre 12/2) feed is pulled from the nearest source of power like a receptacle directly to the light box and another 2 wire switch peg is pulled from the light to the interchange.
Refer to the drawings below for these connections at the wakeful box.
Connection #1 The black hot feed L1 is connected to the white wire in the 14/2 substitution branch.
Connection #4 The black switch leg (#3 to #4) is connected to the black departure to the light (#4 to #5).
Joining #7 The ovalbumin from the light (#6 to #7) is connected to the white neutral in the feed (#7 to N).

Electric current begins at L1 and flows through the colorful wire to the red wire nut connection#1 in the light box. Current and then flows through with the white wire that is starred with black tape (not a neutral) to period#2 on the unvarying pole switch. Inside the switch, after the switch leaf blade is closed, underway flows through the switch blade (purple) from terminal#2to terminal#3. IT then leaves#3and follows the black "switch leg" wire to the red conducting wire freak connection#4 inside the light box then on to terminal#5 along the get down. From#5current flows through and through the filament wire interior the medulla oblongata and out to time period#6. From in that respect current returns through the white neutral telegram to red wire nut connection#7 and back to neutral,N.
This "Light Fed S1" method acting uses the white electrify as a unpleasant. (From #1 to #2) There is no neutral at the switch. There is a white wire at the switch only it is not a neutral. The neutral from the feed goes direct to the Inner Light. (From N to #7 to #6).
But, why would you use a ashen atomic number 3 a hot?
Do, because 14/2 NM-B cable (and 12/2) comes with 3 wires; a black,a white and a ground. This change over wiring method requires 2 blacks from the light to the switch instead of 1 black and 1 white. When this happens the white wire is old as a hot. You might be able to special gild 14/2 with 2 blacks and a ground but it is credible to cost much, hire 2 weeks and call for a lower limit order of 250 feet. Nah, just put black tape on the white wire as shown, you don't receive to covert the uncastrated wire.
There are 2 encrypt rules about using a white telegram as a hot;
- Mark the white wire with a black marker or dirty tape near the ends of the wire
- This Stanford White wire with black tape essential exist misused equally a fiery feed (from #1 to #2) not the interchange leg (from #3 to #4).
✓ Unfortunately this method of connecting the hot and neutral inside the light box seat, as an alternative of internal the switch box, makes it very difficult to access the those connections if any troubleshooting is required. If something is miswired in the lit box you might have to go back awake a 12 foot ravel and take down a 50 pound chandelier to access the connections in the ceiling light box unaware that 1 of the wires will still be hot. Beginners wish think the wiring in the light box is inelastic when the fooling is switched disconnected, but the hot conducting wire that runs from a receptacle directly to the light will still be energized unless the circle breaker is turned off.
Question; A single pole switch does non need a neutral, indeed why would you wishing a neutral in the switch corner?
Answer; Because changes or additions might necessitate a impersonal. Since there is no neutral in the switch box you cannot;
– Install a digital timer– Instal a question sensing switch.– Install a remote pressurized switch– Pull a wire to a 2nd sandy from the switch box. (You will have to detach the aurora.)– Pull a conducting wire from the flip box seat to sum up a near receptacle. (You will possess to find some other power source.)
S1 Method #3 Switch Federal official, Switched Receptacle Paygrad Excellent A+ 🙂
Dismantle Next-to-last
Description
Both the top and nethermost outlets on the receptacle are switched on and off by a wall electric switch.

S1 Method #3.1 Permutation Fed, Half Switched Receptacle
PaygradExcellent A+ 🙂
The world-class style to telegraph a half switched receptacle because it has a neutral at the interchange box where it may be needed for other applications. The method is often used in bedrooms to change on lamps.
PlaneIn-between
Description
Only the top incomplete of the receptacle is switched on and sour by a wall switch. The bottom electric outlet is hot all the time. Major power is fed to the replacement with a 14/2. A 14/3 is run from the switch to the receptacle victimisation the red telegram as a switch leg, the black as an unswitched fast and the white as a neutral. The manufactory tab that connects the top wanted terminal screw with the bottom hot terminal screw is removed. Only the hot tab is removed non the neutral tab. The tab is removed by grabbing it with pliers and bending information technology back and away until it breaks loose.
S1 Method #3.2 Switched and FRS Receptacle
RatingAverage C 😦
There is no more objective at the switch and that can be a disadvantage if you need that neutral for something else at the switch box.
LevelIntermediate
Description
Both the top and bottom outlets on the receptacle are switched on and off by a rampart switch.
Powerfulness is feed to the receptacle with a switch leg run to the switch.
A 2 wire is pulled from a nearby power beginning like a hot receptacle or the electric panel, to course the switched receptacle. Another 2 wire switch stage is pulled from the switched receptacle to the switch. The white telegraph in the 2 wire switch leg is labeled with undiluted tape and in use as a hot.
S1 Method #3.3 Uncomplete Switched and Federal Receptacle
RatingAverage C 😦
There is no neutral at the switch and that can be a disadvantage if you require that impersonal for something other at the trade box.
LevelIntermediate
Description
Only the top half of the receptacle is switched happening and off by a fence in switch. The bottom outlet is hot all the time. Exponent is feed to the receptacle with a 14/2 and a 14/2 switch leg is run to the switch.
The white cable in the 14/2 switch leg is tagged with dim tape and used equally a live. The factory tab that connects the top hot terminal have intercourse with the bottom hot depot screw is removed. Only the hot check is removed not the objective tab.
If you want to add a 2nd, new receptacle to the right of this switch and you run a new 14/2 from this switch box to provender the new receptacle… you take over a problem; there is no neutral at this switch box. You would have to feed your modern receptacle from the first one, at the left, eventide if information technology is 10 feet away.
Call into question; What size screws are used to mount a electric switch to a electrical switch box?
Answer; 6/32
S1 Method #4-1 Combo Switches
When a single device contains 2 or Thomas More switches it is called a combination, combo, piggyback or tandem switch. If you don't have board for a 2 gang box but you need 2 switches then you could employment a combo switch in the concentrated gang box.
Here is what a combo switch looks like;
Notice that this combo switch would use a single gang receptacle plate rather than a switch collection plate. The mounting screw at the top and seat and the shell screw are all size 6/32.

Description Power is fed to the jazz group switch by pulling a 2 wire feed from the nearest source of power. Then 2 switch legs are pulled from the switch to a ceiling fan. A 3 wire has 2 switch legs in it; a red for the light and a black for the fan with the light-skinned being utilized Eastern Samoa the neutral. If you have no 3 wire available you could attract two 2 wires which would leave you with an extra white neutral. One black for the light the opposite black for the fan and one of the whites for the neutral.
A line plot and wiring schematic of a combination switch with a light and a fan.
Many new ceiling fans come with a remote that can hold the light and the fan. This eliminates the need for the second single magnetic pole switch. Since the unused switch is connected to an new telegram that is up at the ceiling, information technology it possible that one could go up into the attic and connect a new wire to this unused wire (and the neutral) and add some new can lights that could then be controlled aside the new switch.
S1 Method #5-1 Multiple Individualistic Poles For One Fan
RatingExcellent A+ 🙂
A rare method used to control a single exhaust rooter from 2 or more different bathrooms. The exhaust fan is set in a central placement, like an attic, and well-connected to channel work that comes from each (lets say) 3 bathrooms. Each bathroom has a single pole switch that can turn the fan on or off but the fan can only be turned off at the place where IT is turned on.

Description Top executive is fed to a disconnecting switch located near the buff. A 2 conducting wire replacement leg is pulled from the fan to the 1st closest bathroom switch and some other 2 wire from the 1st switch to the 2nd and other 2 conducting wire from the 2nd to the 3rd. The white in the 2 wire is identified with black tape and used as a hot, non a neutralized and not the switched hot that connects to the fan.
At the fan box; the sensual feed is related to one concluding on the disconnecting switch. The white (with Black person tape) is connected to the other terminal on the disconnecting trade and feeds powerfulness to one terminal on each bathroom single celestial pole. The black switch leg is connected to the other terminal on each bathroom single pole and then now to the fan. The white from the fan is connected to the white neutral in the feed.
