Title: How to connect the light bulb wire
introduction
Recently, discussions on home circuit installation and light bulb wiring have become a hot topic. With the popularity of DIY home renovations, many netizens have developed a strong interest in how to properly connect light bulb wires. This article will combine the hot contents of the entire network for nearly 10 days to analyze the correct connection method of light bulb wires in detail and provide structured data for reference.
1. Basic principles of light bulb wire connection
Before connecting the light bulb wire, you need to understand the basic circuit principles. Home circuits are generally single-phase alternating current with a voltage of 220V. As a load, the bulb needs to be properly connected to the live wire (L) and neutral wire (N) to work properly.
2. Steps for connecting light bulb wires
1.Power off operation: Be sure to turn off the power before operation to ensure safety.
2.Identify wires: The live line is usually red or brown, the neutral line is blue, and the ground line is yellow-green.
3.Peel the insulation layer: Use a wire stripper to peel off the insulating layer at the end of the wire to expose about 1 cm of copper core.
4.Connect the wires: Connect the live wire to the L-end of the bulb, the neutral wire to the N-end, and the ground wire (if any) to the ground terminal.
5.Fixed and tested:Pack the connection with insulating tape and power on and test.
