blue wire in junction box Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet. Blue and yellow wires are hot wires for ceiling fans and three- or four-way switches. White or gray electrical wires are neutral wires. The most common screw sizes for metal junction boxes are 6-32, 8-32, and 10-32. The 6-32 screw size is commonly used for outlet screws and cover plates, while 8-32 is often .

The NEC 2023 includes specific provisions for sizing junction boxes. These requirements ensure that boxes are large enough to accommodate conductors, splices, and other components without causing damage or excessive heat buildup.
The wiring sounds perfectly normal to me, for US standards: white wire = neutral. black wire = hot (unswitched) red wire = hot (switched) When the switch is on, the black and red wires are effectively connected together at the switch, so the voltage between them is zero. Wiring a light fixture? Don't be confused by the number of electrical wire colors you find—we've got just the guide to help you decipher their color .

Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet. Blue and yellow wires are hot wires for ceiling fans and three- or four-way switches. White or gray electrical wires are neutral wires. Yellow and Blue Wires. These wires usually come in pairs and pulled in conduits. They are used as hot wires and control electrical items like lights, switched outlets, and fans. Blue wires are generally used in a three-way and four-way switch applications by travelers. On the other hand, yellow wires are used as switch legs. Copper and Green Wires Wire color codes are black, red, white, bare copper, green, white or gray, and blue or yellow. White, gray, bare copper, and green are the only wire colors that the NEC mandates must indicate a specific purpose. White or gray must be used for neutral conductors. Bare copper or green wires must be used as ground wires.
How to wire an electrical junction box. A junction box is used to add a spur or to extend circuits and direct power to lights and additional sockets. Advice on wiring electrical junction box with easy to follow junction box wiring diagrams, including information on 20 and 30 amp junction boxes.
