Choosing the correct wire gauge is crucial for electrical safety and system stability in home improvement. Below is a reference guide for selecting wire specifications based on common residential scenarios to help you plan your circuit layout scientifically.
BV Wire (Solid Core): Ideal for Fixed Wiring
1.5mm²: Dedicated to general lighting circuits, handling standard lamp loads.
2.5mm²: Suitable for standard power outlets and regular air conditioning lines, balancing safety and cost.
4mm²: Specifically for high-power appliances like electric water heaters and cabinet AC units, ensuring stable power under high loads.
BVR Wire (Stranded Core): Ideal for Flexible Bending
1.5mm²: Used for socket connections, offering ease of wiring in confined spaces.
2.5mm²: Applicable for regular AC lines, offering superior flexibility for easier installation.
4mm²: Designed for high-power equipment such as water heaters or standing AC units; the stranded structure offers better heat dissipation and reliable connections.
