关于零线,火线的知识
单相三线制插座插孔的定义是左零（N，Naught wire，蓝/白色）
右火（L，Live Wire，红/棕色/绿/黄）
上地（E/PE/G，黑色/黄绿双色） 最常见的用法是蓝线为零线，棕线为火线，黄绿线为地线，我剪开过不少国标插头，不管土牌子还是洋牌子，都是这个用法
Black= AC power at line voltage
Red= AC power at less than line voltage
White;neutral Gray = AC Neutral conductor at less than line voltage
Blue= Ungrouded DC power
Blue/whitestripe or white/blue stripe = DC grounded voltage
Orangeor Yellow = excepted voltage that may be energized while the main disconnect isin the off position
Green;Green w/yellow stripe = equipment grounding conductor
学习了,谢谢
