Level Beginner Description Power a hot and a neutral is fed to the switch with 1 switch leg run from the switch to 1 light.
A 2 wire feed is pulled from the nearest source of power like a receptacle or the panel to the switch. A 2 wire switch leg is pulled from the switch to the nearest light.
Below is a line diagram and a wiring schematic of a basic 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 hot on the left and the neutral on the right. Wiring schematics are more like a drawing of the real thing, 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 not shown. A photo, diagram and schematic of a basic single pole switch circuit with one light. Basic single pole switch c ircuit with one light.
The cord plug at L1 hot and N neutral represents power feeding this circuit. You could plug it into a hot outlet and this switch and light would work. To make switch wiring easier, try to visualize how the electrical current is moving through the circuit.
For example, look at the wiring schematic and say to yourself, the current is moving. From the hot Electrical current begins at L1. This current is coming from the electrical panel or a nearby receptacle. From L1 , the current flows through the black wire to terminal 1 on the single pole switch. Inside the switch, after the switch blade is closed, the current flows through the purple switch blade from terminal screw 1 to terminal screw 2. The switch leg wire is only hot when the switch is on closed.
From terminal 3 current flows to a small point on the base of the light bulb where it then enters the bulb, flows through a highly resistant filament wire and then exits the bulb through the base shell which is connected to terminal screw 4 on the light fixture. The part that is not shown is how current continues from the neutral to the panel to a transformer coil, through the coil in the transformer from N to L1 where it starts all over again.
Level Beginner Description Power is fed to the switch and 2 separate switch legs are pulled from the switch to 2 separate lights. The first switch 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.
A line diagram and wiring schematic of a basic single pole switch circuit with 2 lights. Each light is 50 feet away from the switch. If you install 2 switch legs, one from the switch at 2 to the light at 1 50 feet away and a second switch leg from the switch at 2 to the light at 3 50 feet away you would use feet of wire saving you 50 feet of wire. This savings only applies if the switch is between the lights.
In these first 2 methods we fed power to the switch box. In the next method power is fed to the light box. For some reasons why folks tend to avoid this in practice, take a look at my answer to this other question. Yes it can. Different areas have rules for load on a circuit. As long as you don't have load issues you are fine doing this.
Lots of people don't mix receptacles and overhead lighting to keep the room lit if there is a power failure on one however this is not a hard rule and is just good practice. The wiring for the light has to be 12 gauge, and the light switch has to be rated for 20 Amps. Can't have 14 gauge wire or 15 amp switch anywhere on a circuit that is protected by a 20 Amp breaker.

This is true as long as you follow other rules, such as matching the breaker to the equipment and to the receptacle s. By the way, this has nothing to do with the distance. The amperage of the outlet must never exceed the amperage of the circuit.
According to National Electrical Code, only a 15 - amp or 20 - amp electrical receptacle can be installed to a 20 - amp circuit. However, a 20 - amp GFCI outlet may not be installed to a 15 - amp circuit.
Electrical plugs designated as 20 - amp will not fit into 15 - amp outlets. A 15 - amp circuit is usually served by gauge wire and is protected by a 15 - amp circuit breaker or fuse. A 20 - amp circuit , protected by a 20 - amp breaker or fuse, must be served by gauge or gauge wire. It's referring to single receptacles, I.
You install a 15A single receptacle , and code requires that to now be a 15A circuit , with a 15A breaker. Why: The 20 amps are required vs.
Think toaster ovens, blenders, and mixers. It is perfectly acceptable to use 12 gauge wire on a 15 amp circuit. It shouldn't, many older homes were wired with 12 gauge throughout. Apart from that, it is actually explicitly allowed by code.
A 12 gauge wire is rated for 25 amps. NEC only allows for it to be protected at a max of 20 amps unless following an exception for motor loads.
