Four, and then the (AC) region of the L, N access to the 220V power supply (2.5 of copper core wires), such as the installation position is low, the best grounding wire.
再将变压转换器的（AC）区域的L、N接入220V电源（2.5的铜芯电线），如安装位置较低，最好接上地线。
Larger magnet wire can then be used which increases the power of the electric motor using the armature having the larger magnet wire.
于是可以使用更大的磁线，其增加了使用具有更大磁线的电枢的电机的功率。
In fact as the fulling- mill was there, although not then in use, its beam moved with extreme power would serve to stretch out the wire by rolling it round itself.
压榨机就在这里，而且现在正闲着，只要用巨大的力量推动卷轴，它就可以把铁丝拉长并卷上去。
Firstly, the existing methods of the three phase power measurement in the teaching materials are introduced. And then another three connection methods are suggested for three phase four wire circuits.
首先介绍了现有教材中已给出的三相电路功率的测量方法，进而提出了三相四线制三相电路功率测量的另三种接线方法。
