Electric with rigid foam
你好，
我在这个网站上阅读了很多很棒的信息，以指导我如何隔离我对1940年代房屋的完整重建。我的第一个故事是高于级别的煤渣块，我继续2英寸内部刚性泡沫板，因为我将房子完全剥落到里面的街区。我计划用2×4进行毛茸茸，主要是因为我从巨大的建筑工地上抢救了数百个，他们将它们扔进垃圾箱。另外，这给了我更深入的电源插座盒。
My question does not involve the insulation itself as I have found bountiful information to guid me but on this topic. I was curious how everyone runs their electrical in situations like this.
我有很多选择可以将所有东西都拉到天花板上，然后将它们放在毛茸茸的条之间，一半的房子在水箱上，所以从地下室传来的是麻烦。我想我想知道别人会做什么，因为这将使我几乎花了两倍的电线来运行天花板上的所有东西。我还想知道我是否在毛茸茸的条带后的泡沫中刻了一条小隧道，然后用钢板盖住了十字路口，但我担心这对泡沫板的完整性有什么作用。
I have lots of electrical experience and understand the code book but nothing really fits into this scenario as you wouldn’t normally build a house this way. Lets just say Im much more fluid with new construction (residential, Im very unfamiliar with block). Any help would be greatly accepted.

Good morning Eharm,
我敢肯定，您会很快就如何运行电缆来获得一些很好的建议。但是，这可能是与建筑物检查员进行的很好的对话。代码书是一回事，是单个检查员对在非标准组件中应如何做的解释是另一回事。
这可能是导管的好应用。使用EMT可以运行一些主跑步，然后将MC鞭子放到单个设备盒中。这为您提供了到处的装甲布线，而且跑步量更少，因为一个导管跑步可以携带多个电路。如果使用常规的NM电缆，则需要使用指甲板等保护它。
另一个选项可能是蓝精灵（蓝色弯曲物，ENT）。任何导管系统还具有允许将来的接线更换而不打开墙壁的优势，但请记住，Al接线盒需要可访问 - 您不允许将交界处埋在墙壁内。
如果您要在一层刚性泡沫的顶部用那些2x4的墙壁框架，那么您可以在墙壁腔中以通常的方式进行接线。通常会“向上”奔跑，进入天花板，然后越过。很难在不实际看到该站点的情况下推荐任何特定的电缆通路。您只需要一条可行的途径，该路径涉及所需的位置。尝试尽可能多地沿着通用路线运行电线，以保持整洁和高效的效率。

账单，
Thanks for you input appreciate it. I like the thought of having EMT carrying multiple circuits with the MC whips that can cut down on my wire backtracking, I am trying to stay away from any NM wire is these walls. I believe if I plan accordingly using the method you described I can actually make my junctions in the basement for the majority of the house and just run the whips up that way they unctions are exposed as per code.
我很好奇想法，因为“上下方法”几乎将我的电线消耗倍增，因为在旧房屋中非常奇怪（对不起，几乎不可能描述或显示图片）。至于2x4框架，我计划将它们用作毛茸茸的条，而不是节省空间的实际框架。使用2英寸泡沫和3.5英寸框架和干墙，我将失去每个房间的6英寸，如果我转动它们并将它们用作毛茸茸的条，它仅切入4英寸的房间。听起来并没有太大的区别，但它对我的厨房和岛屿清除率产生了重大影响。
Thanks you have given me lots to think about and consider.

Glad to help.
Yes, you can put all the junction boxes in your basement. Junction boxes need to be accessible per code, but it doesn't say "easily" accessible. Locating the junction boxes in tiny crawlspaces is OK, as is locating them in damp basements and anywhere else that someone can get to. You just can't cover them up with drywall, for example.
我建议使用“4”(4-11/16”)方盒子, 2-1/8" deep, for your junction boxes. Those boxes give you more room for splices, and more useful knockouts (usually 3 concentric knockouts on each side). If they're all going to be in a basement, you might as well use the larger boxes and make your wiring work a little easier.
If you use your 2x4s on the flat as furring strips, you can use shallow (1-1/2" deep) depth boxes and mud rings which will fit nicely in your reduced size wall cavities.

如果您通过泡沫在螺柱后面运行罗马克斯，那么您应该没有问题。您只需要指甲板，如果电线距离表面小于1 1/4”，而平面上有2x4，电线足够远，我仍然会放置指甲板。罗梅克斯可以通过隔热材料运行，将其放置在凹槽中没有问题，在这里始终在这里喷涂布线。
您的检查员可能需要一些Zipties到螺柱上以固定电线。
