You said "把红线断掉了, 保险就不跳, 可是除了这个插座, 没有一个照明和其他插座有电." I can answer your question, the red and black is two different phase live wire from two different circuit breakers. (Did you replace a new (插座) for these two circuit recently?), or/and, was anything change to the (插座) before all this happen??? if you can take a picture of how was it connected oreginally, I may be able to give you a better answer. If the red wire connected causes the breaker to “POP”, it sound like the device (插座) has a shorted component inside where the red wire is connected... I would suggest you to replace that device (插座). If you have the Black and Red connect to the same (插座) make sure you cut out the "bridge" on the top between the two terminal screws. Take a good look of the (插座). two screws on one side is silver screw and they have bridge connected on top, connect neutral to it. The other side has two golden colour screw also connected with a "bridge" on top, live hot wire connects here. BUT you can only connect one single phase to one of these two screws, Not two different phase. Otherwise circuit breaker will pop. Good luck! 把红线断掉了,可是除了这个插座,没有一个照明和其他插座有电, this statement already answer your own question, because the red wire is carrying one live phase, if you disconnect it, the voltage will not connected to other area.

找个电工吧。 -earthvilledeveloping(地主老财); 2008-1-15 (#4188580@0)

找了2个电工了,还是没解决. -xiaotaozi(小桃子); 2008-1-15 (#4188609@0)

把所有Switch打到OFF，合上总闸，再把Switch逐个打到ON，就可以找到哪个引起的短路。看一看那个Switch管的是哪几个电器，再缩小范围逐个排查。 -copperbean(豆泡松果之铜豌豆); 2008-1-15 (#4188583@0)

谢谢. 发现一个插座很怪,有黑色,白色和红色3根线.只用黑白两线插座就有电,但其他插座和照明还是没电.红线一加上就跳闸.其他开关和插座就只有黑白两线.这红线是什么呢? -xiaotaozi(小桃子); 2008-1-15 (#4188606@0)

对不起，这我就回答不了了。如果你对这个有疑问，或者找个电工咨询，或者拍一张照片，拿到RONA或者HD问一问，他们可以给你比较详细的解答。 -copperbean(豆泡松果之铜豌豆); 2008-1-15 (#4188629@0)
你什么也没动它自己就跳闸了?N年前我家也跳过一次,什么也没做推上就好了...闸箱老保持一个姿势累了....? -dedade(不吃就是不吃); 2008-1-15 (#4189182@0)

normally red and black should be power lines, 110v each, white should be neutral. if a power outlet has both red and black, it means it's for 220v devices. -ywgan(gan); 2008-1-15 (#4188927@0)

1，加拿大的民用电是110V的，应该没有220V的。2，两根110V的电线不能提供220V电压，此乃误导。 -copperbean(豆泡松果之铜豌豆); 2008-1-15 (#4188980@0)

对，就是通过误导产生２２０V -tjhong(我检讨); 2008-1-15 (#4188985@0)

豆豆小学跳了两级所以语文没学好很多汉字不会写中学老参加国际数学奥林匹克竞赛所以物理耽误了大学是体育尖子保送的所以英文不用学习。。。。多优秀阿。。。。。。。。。 -ysysning(豆泡松果之樱桃果果); 2008-1-15 (#4189413@0)

好不容易觉得自己除了八卦之外还懂点科学，谁料到让你们打击得灰头土脸的，郁闷！ -copperbean(豆泡松果之铜豌豆); 2008-1-15 (#4189431@0)

you are right... 数学?物理? only jerks care those.... we elites care how to 8卦, right ,sis? -win(秋天的菠菜); 2008-1-16 (#4191241@0)

1 两根110V的电线不能提供220V电压-－－－－-可以当成 220v用，也能驱动220V的电器。（注意接地的问题） 2 加拿大的cooking stove 就是用两根110V来产生足够的功率的。查查你家的stove ，就是接在四孔的插座上，不是普通的3孔的 -dyno(dyno); 2008-1-15 (#4189065@0)

这这这，我猜这是典型的三相四线吧。 -tjhong(我检讨); 2008-1-15 (#4189087@0)

学过电工原理的才知道啥叫交流电的相位。 -copperbean(豆泡松果之铜豌豆); 2008-1-15 (#4189109@0)

两根110V的交流电啊，相位不同是不能这么简单相加的。学过电工的同志上来支持一下吧，这可是原则问题。 -copperbean(豆泡松果之铜豌豆); 2008-1-15 (#4189100@0)

忘了在哪看来的,变换连接民用电确实有220V的,这个<<<<无牌电工>>>>>肯定能给个正确答案....等待ING -dedade(不吃就是不吃); 2008-1-15 (#4189163@0)

In canade, normally it is 240V, 1 phase get into the house, -me72(xy); 2008-1-15 {277} (#4189175@0)
they have special tranformer to get that voltage power. So, there are two lives and one neutral. For the commercial building, the incoming services can be 120v/208v, 3 phase( three lives, one neutral) or 208v, 1 phase (two lives, one neutral) or 120v ( one live, one neutral),

谢谢大家.可是怎么解释红线一接上就跳闸呢? 现在把红线断掉了, 保险就不跳, 可是除了这个插座,没有一个照明和其他插座有电. 还有用万用表查短路怎么才是最正确的方法? -xiaotaozi(小桃子); 2008-1-15 (#4190157@0)

有红线那个插座和别的插座是不同的,那上面的孔是不一样的.你这120伏的电器是不能插进去的,同样,240伏的电器也不能插进那没有红线的其他插座里. -elephantsong(大笨象); 2008-1-15 (#4190181@0)

本文发表在 rolia.net 枫下论坛Most of the house in Canada has two phases (2 相”) one neutral and one earth ground wired to the house’s main circuit panel, each phase with the neutral should have voltage 110vac and the two “hot” phases offers 220vac. The electrical code requires the “Hot” wire needs to be identified in red or black. And the neutral will be white, ground is green.
Each phase with the neutral will be measured 110vac; every low voltage household appliance uses this voltage to do work. It is called single phase two wire system. Of cause, the earth ground wire is there for personal safety protection, in the case of electrical appliance has electricity leakage, the ground wire diverts the electricity go though the earth ground instead of human’s body.
Any of the two phases without the neutral, will be measured 220vac, this also called two phases three wire circuit,(household high voltage), which used on high power appliance such as cloth dryer, range top, oven, air conditioner.
Cook top/oven/stove , have two phases there wires circuit, which includes two phases of the 220vac, and the neutral, this neutral and any of the single phase offers the 110vac for the appliance’s control circuit,更多精彩文章及讨论，请光临枫下论坛 rolia.net
