In the U.S. a few days ago, the ground wire is green, yellow-green stripe or bare wire, the neutral wire should be white or gray, and the circuit wire

In 1953, NEC changed the color of the ground wire to green or bare wire. Green is also prohibited for circuit lines (such as live and neutral lines).

The first National Electrical Code (NEC) was proposed by NBFU in 1897, and it also ignored the standardization of wire color issues.

Black, white, green, red, blue, orange, brown, and gray. The color of the insulating sheath on the outside of the wire usually has its own meaning.

After being tried by many users, it has won unanimous praise from experts and users. We are actively expanding production scale to meet market demand.
