Yellow wires are used as switch legs to ceiling fans structural lights and outlets paired with light switches while blue wires are usually used as travelers for three or four way switches. For this reason they are also known as travelers. These wires usually come in pairs and pulled in conduits. The hot from the source is spliced to the black wire running to the combo and to the input side of the switch. They are used as hot wires and control electrical items like lights switched outlets and fans. The red wire from the light is connected to the output on the switch and to the hot terminal on the light at the other end. Yellow and blue wires are sometimes used in more complicated circuits. The switch wiring is all the same but the switch wire cable c leads up to a different set up. The two conductor cable from the ceiling box to the light switch is supposed to have the white conductor re identified with another color because it is not being used as a neutral but as a. White and gray electrical wires the colors white and gray indicate a neutral wire.
Black wire this is the hot or load wire.
That means it connects to an electrical panel s neutral bus bar. The white neutral from the source is connected directly to the light fixture. There is a chance that if your house has these old wiring colours the switch drops may be from a loop in loop out radial lighting circuit done with junction boxes rather than ceiling roses as shown in fig 2. If they are they are used as hot wires to conduct current between switches and poles. The above two conductor switch wiring diagram is from older homes and is likely not used much anymore depending on which code book is in force in each jurisdiction. The switch wiring is all the same but the switch wire cable c leads up to a different set up.
That means it connects to an electrical panel s neutral bus bar. Bare copper green wire this is your ground wire. If they are they are used as hot wires to conduct current between switches and poles. Since red wires still conduct current they are considered hot. These wires usually come in pairs and pulled in conduits. White and gray electrical wires the colors white and gray indicate a neutral wire. Blue wires are generally used in a three way and four way switch applications by travelers. Black wire this is the hot or load wire. Choices of light switch wiring diagrams. Yellow wires are used as switch legs to ceiling fans structural lights and outlets paired with light switches while blue wires are usually used as travelers for three or four way switches.
The two conductor cable from the ceiling box to the light switch is supposed to have the white conductor re identified with another color because it is not being used as a neutral but as a. For this reason they are also known as travelers. Yellow and blue wires. The switch wiring is all the same but the switch wire cable c leads up to a different set up. The grey wire in cable d is a switched live and the blue wire in cable c and black wire in cable d are permanent lives and thus should be marked with brown sheathing at each end as shown. Blue wires are generally used in a three way and four way switch applications by travelers. White wire this is the neutral wire. These wires usually come in pairs and pulled in conduits. Two way light switching 3 wire system new harmonised cable colours note. White and gray electrical wires the colors white and gray indicate a neutral wire.
Basic knowledge of how to wire a light switch. Since red wires still conduct current they are considered hot. Yellow and blue wires. They are used as hot wires and control electrical items like lights switched outlets and fans. The two conductor cable from the ceiling box to the light switch is supposed to have the white conductor re identified with another color because it is not being used as a neutral but as a. That means it connects to an electrical panel s neutral bus bar. These wires usually come in pairs and pulled in conduits. Bare copper green wire this is your ground wire.

If they are they are used as hot wires to conduct current between switches and poles. Red wire this wire is used for 3 or 4 way switches and will connect the switches together so they can each control your lights. Yellow and blue wires. Black wire this is the hot or load wire. Yellow wires are used as switch legs to ceiling fans structural lights and outlets paired with light switches while blue wires are usually used as travelers for three or four way switches. For this reason they are also known as travelers. These are called travelers and typically used for two way switch wiring. They are used as hot wires and control electrical items like lights switched outlets and fans. The two conductor cable from the ceiling box to the light switch is supposed to have the white conductor re identified with another color because it is not being used as a neutral but as a. The white neutral from the source is connected directly to the light fixture.
Basic knowledge of how to wire a light switch. A simple standard electrical circuit has a black or red hot wire that carries power from the power source to the device e g switch fixture outlet appliance a white neutral wire that carries the power back to the power source and a green or bare copper ground wire that connects the device to the home s grounding system. That means it connects to an electrical panel s neutral bus bar. The switch wiring is all the same but the switch wire cable c leads up to a different set up. For this reason they are also known as travelers. The two conductor cable from the ceiling box to the light switch is supposed to have the white conductor re identified with another color because it is not being used as a neutral but as a. White wire this is the neutral wire. If they are they are used as hot wires to conduct current between switches and poles. They are used as hot wires and control electrical items like lights switched outlets and fans. Bare copper green wire this is your ground wire.
