电源接线问题

没有.风扇本身就是。

if the spice point isn't enclosed in a metal box, i am not sure if it will be against code. it's not safe for sure. i had a baseboard heater suddenly stopped working. i opened the connection box, found out that the circuit was short and wires were burned and melt. if it were not in the enclosed box, it would have been very easily to start a fire.

I don't know what you are talking about. The fan itself is a enclosed metal box, and you have a ground wire attached to its body. That is how all those cheap hood fans from builder are installed.
Wire can get short any where, as you said in your case, it was in the connection box. How can you avoid it by adding another connection box?

So you have your connection boxed added? Whatever just a reminder. If you have done it correctly just ignore my post

What I'm talking about is if the circuit shorts and get some sparks, if not inside a connection box, the result could be drastic. If the house fire is caused by a electric circuit short and the installation wasn't done by ESA code, insurance company might want to say, sorry, your claim is denied.

You are not reading my post: Hood fan is used as the conjunction box in this case. All the connection is made inside the fan's box.

There is not much I can say since you understand the code better than all the builders and the hood fan manufacturers.

Thanks every one. I followed 没有网名 suggestions and it works.
Wired the 电源线 inside 抽油烟机。如果用connection box, you must put connection box inside 墙里面, otherwise against code.

Be careful with adding another conjunction box in this case.

I think you can only install a wall plug if you don't want to cut off the wire. If you do cut off the plug and try to connect it to a new conjunction box, then you better make sure your conjunction box is not blocked by the fan, since the conjunction box can't be blocked. Since the fan is screwed on the wall and cabinets, so this may be a real violation of the code. (I am not sure since I am not a electrician)

I would like to know where to install the conjunction box in this case, without cause some an eye sore. And make sure you get a inspection done, since by adding a conjunction box, you are actually changing the wire in your house. In Ontarion, you have to have a inspection any time you do any wiring.

apparently you know code better than me. i just asked if no connection box added will against code, you already know you can use fan itself as metal enclosure and that is allowed by code. i am just wondering what caused you jump to conclusion that I understand the code better than all builders and hood fan manufacturers.

i had removed the builder provided hood fan and installed the one i wanted. both of them has a separated metal enclosure box at the place where the wires are connected. if there's no need for that, why hood fan manufacturer would put an additional metal box there.

Get ESA certificate whenever you changing the wire is a good idea. Peace of mind that the wiring is safe and cover your a** if bad thing happens in an unfortunate event.

not to avoid short circuit, the small metal box is to keep the high temperature/sparks/fire caused by short circuit within that small place, instead of spreading out to reach some flammable materials. that's what I understood for the purpose of the metal enclosure box anyway. well, you can at me again for that i understand the code better than builders and manufacturers

I have been help fiends and my self replaced the hood fans in new houses built by Minto, Mornarch, Olympia, Richcraft, Claridge. They were all installed the same way - there is NO another conjunction box inside the fan. The wires are connected in side the fan in the same way.

I not a electrician, nor a expert on code. What all I am doing is just 依葫芦画瓢. I just assume the builder know the code the best, so they installed the fan that way. And I know manufacturer knows that the best, other wise their products won't pass the certification. Since you are saying what they do it violation of the code, so the only conclusion I can make is you are better than them on understanding the code.

oh boy, here is what i had said,

i am not sure if[/COLOR][/B] it will be against code.

here is what you read

Since you are saying what they do it violation of the code, so the only conclusion I can make is you are better than them on understanding the code.

by the way, even the cheapest hood fan i saw(~35 bucks), it has a built-in metal box with a metal plate cover for the location where the wires are connected.

here's what esa says,

wire splices must be contained in junction boxes, which are required to be covered and accessible in case you need to work on the wires in the future.
