起重设备，安全起见，2.5好
可以，最好是用3x2.5+1x0.5
最好2.5的线
要是你们那里的输出电压比较高的话没事，我们这里的电压现在一般都在240以上
买2.5的吧！有足够预留好点

保存至快速回贴一台电机4KW的选用什么电缆好,截面多大的,还有开关?或并联的三台4KW的电机需要多大的线,和开关?

一台4KW电机的电流也就9A,选用电缆要看你的敷设环境和要求,截面3x2.5mm2,开关选C45N 10A/3P D型

扫描下载二维码308V电机 50HZ 3KW 1410r/min 6.7A如何改成220V电压，该用多大的电容及线该如何接，请高手指点。不胜感激
如果电源为380V电压时电机接线方式是Y接，在使用220V电源时只需将电机接线盒内连接片改为D接便可，不需要什么电容器辅助的。
你安装个变频器3千瓦的就可以咯。220v变3相220v就可以啦！把Y接改为角接就可
绕组不同的，去买合适的功率的单相电机就行，3千瓦四电机能卖一二百块钱
