今天自己装range hood, 挖洞的时候,不小心把220V的那根cable切断了,这根线
好像崩得特别紧,估计想把两截拧在一起是不行了。有什么办法把它们接起来吗?还是
只能找电工让他们想办法,不知道找电工要多少钱?他们不会要把dry wall整个给切开
来重新布线吧?

通常220V是两条火线,在美国是指2条相差(相位差)110V的输入,主要是给电炉,Oven
用的,你要是弄断了220v就是说两条线都断掉?,基本上不可以把断的地方重接(code
不允许),你要到你总开关那看要是有1尺富裕的线可以伸伸,不然还是重新拉线,如
果你知道原理这个比较简单,大概这组线就是红色和黑色

看地区,我们这里都是穿管的,所以方便换,但有些地方就直接布线,这样就比较难,
像楼上说的用两个接线盒也未尝不可

用box是不是还得找东西把两根线绝缘分开吧?
外面要用什么包起来呢?

220V should have 4 wires (2 hot, red and black, 1 natural, white, 1 ground,
usually bare).
You said only 2 got cut, I am little confused.
Depending your local code, in most area of US, if run is more than 50 feet,
a disconnect is required, you may rerun the part from the disconnect.
Local electrical codes are not the same as the National Electrical code. The
local authority having jurisdiction in your area may have different codes
