For the entire line, the number of branch circuit should not be too small, generally should be light to go all the way, air conditioning to take the two road, the outlet to go three to four.
对于整个线路来说，分支回路的数量也不应过少，一般应该是灯走一路、空调走二路、插座走三至四路。

When the unit is plugged into an AC outlet it automatically self-tests, checks for correct polarity and tests the integrity of the equipment ground, i. e. the green wire in the branch circuit.
当单位自动地被塞住入ac出口它自检、检查对于正确极性和测试设备地面的正直，即。绿色导线在分支电路。
