空气密封电气盒
我看到有很多关于密封塑料电气盒的信息，但不在用泥圈和管道密封标准电箱。金属电气盒中有很多孔和接缝，我正在考虑使用用于密封管道工作或乳香的铝胶带，以密封所有孔和接缝。还是有更好的方法来密封它们？这是我可以进入盒子后面的新建筑。

虽然我自己没有尝试过，但乳香可能会为此工作。箔胶带将在平坦的区域上工作，但可能难以在导管配件周围使用。我通常使用红色的高温硅胶填缝，但我认为乳香会在金属盒上工作较少，因为你可以迅速传播它并密封一切。
The only issue I could think of is that many metal boxes have a film of oil on them left over from the manufacturing process. This oil film might cause problems with adhesion of the mastic. Wiping the box down with an acetone soaked rag before applying the mastic would fix that, and isopropyl alcohol might also work as a slightly less aggressive solvent.

关于石油的好点。在应用任何内容之前，我需要擦拭它们。
I don't know where you are located but in Canada you can buy vapour barrier boot made for electrical box. I suppose it's available in the US as well

+1对于插座盒的蒸汽屏障靴，但您也可以使用密封塑料盒，这是我在电气工作时使用的。
In both case you will still need to seal with caulking where the wires enter the airtight plastic box or the vapour barrier boot.

作为一个人的使用ti花了的时间n tape in the most asinine situations, I'd try the mastic first. Tin tape would work great in this situation, but it takes a lot of time and zen like patience peeling the backing, folding it lengthwise to get them in the corners, getting it around the conduit, missing, retaping, peeling it off your fingers. Etc.
如果你已经有管道到位，加拿大蒸汽靴将是痛苦的。
用刷子或硅胶用丁腈手套的玉米粉碎，在我的世界里，我的世界将是如此迅速。
罐头泡沫是我想的寿命中最不好的。但仍然比一无所有，仍然是一个非常好的选择。如果你有很多事情要做，那也是最快/最简单的。获得低膨胀，窗户和门型泡沫和泡沫枪，你会很好。

Salesi，
Just one thing to add to your potential sealing headaches. I encountered a surprise problem in my former house, which occurred despite sealing the boxes with metal tape. (yes it is tedioius) Code for that home required conduit for all wiring as it appears your's does.
I don't believe outlets are airtight, based on a surprise water drop falling from a ceiling outlet. I had placed it there in case I went ahead with a projector TV system. I first thought I had a roof leak, but discovered the outlet cover plate was full of water. I then realized heavy condensation had collected on the wiring passing up into the conduit.
电工沿着上方的盖子沿着上方的托架运行导管，以提供屋顶风扇的接线箱位置，然后进一步向前管道，然后弯曲进入出口的箱子位置的背面。温暖且相对潮湿的空气通过出口，进入导管，在那里它冷凝并追踪电线。非常出乎意料，幸运的是没有创造一个短暂的。我不得不在电线周围压制密封腻子，并进入导管以防止进一步冷凝。天花板灯箱会这样做。
This may be a one in million situation, but if you think of conduit as very small ductwork, it may help you head off a similar occurrence. In my new house I spent a good deal of time sealing the envelope and elected to not fuss with sealing the plastic boxes and Romex type wiring. I am gambling perhaps, but I don't think I am going to see any significant air exchanges into the wall. All but a few wiring locations are contained inside the conditioned space and should be neutral as far as moisture transfer is concerned. The exit points for the garage, exterior lights and outlets were of course heavily sealed. Stainless wool and sealant combined to prevent mice on top of air. Do check the points where conduit passes through your WRB and garage if a shared wall. Mice are masters at squeezing in along conduit.
容器绝对不稳定。开关可能更好，但仍然不稳定。据我所知，任何一个设备都没有密封版本。
我过去所做的就是将一些大型的背杆塞进导管中，我认为可能会泄漏空气（或声音 - 它令人惊讶的是，我们如何通过导管长度携带。如果您需要将新电线拉入导管，则填充至少几英寸的后杆，有助于阻止气流，但仍然很容易移除。
它还值得指定在仪器中使用压缩联轴器而不是设定螺杆联轴器。一种不论成本都没有太大，但压缩类型泄漏得多。这将有助于将堆栈效果从房屋内部通过导管绘制空气。
