Fire wire generally uses red (yellow is optional)
The neutral line generally uses blue, green, and yellow
Yellow and green color for ground wire
Color: Red, blue, green, yellow, yellow and green
Electric Wire Model Purchase Guide
- Lighting generally uses 1.5 square single core hard wire (BV1.5), divided into live wire and neutral wire according to different colors
- Sockets generally use 2.5 square single-core hard wires (BV2.5), and air conditioners above 3 HP generally use 4 square (BV4) or above single-core wires
- The home bus generally uses a single-core wire of 6 square meters (BV6) or more
- Please consult online customer service for specific configuration and quantity, but please purchase according to the requirements of the electrician first
