I like all of my smog machines (i.e.: power generators) to be outside of my structures, so as not to suffocate the inhabitants. (Yeah, I know there's not an actual mechanic for that. But stick with me here.) I also like all of my buildings to be fully enclosed, with solid-looking walls - not those shabby-looking, hole-y walls.

Unfortunately, there doesn't seem to be a construction option that allows for this and at the same time permits routing of wires through those walls from the generators. For now, I've been finagling the wires through the slight gap in a section of curved roof. But this tends to be really tricky, requiring extra-special placement of the generator and conduits, and I don't like those types of roofs either.

Is there something I'm missing? Is there a "right" or "easy" way to bring power through the walls? (Non-console solutions preferred - I play on XB1.)

  • I usually set conduits and/or pylons around the house and place my electrical objects near the walls instead of in the center of the rooms. Electricity have an AoE for bulbs/tvs/etc, you don't need a wire inside. The exception to this is items needing a direct link, like a terminal. Commented Jan 6, 2016 at 0:21
  • @Pierre-LucPineault The issues I have aren't due to objects not being close enough to the conduits. Whenever I have a problem, I verify the conduit is getting power (or not) by hooking a construction light to it with a cable.

Put "wall conduits" (Power > Connectors & Switches) on the inside and outside of the structure, and the power will transmit between them.

  • I'm reasonably confident I've tried this to no avail. I specifically remember attempting this recently, when I built a special facility for my Signal Interceptor, especially because of its large power needs and having certain connectors on the second floor. I ended up putting the generators on the roof and routing it down through the roof access shack. I guess I could still give this another go to be sure.

    You can see an example of this in The Castle, its all set up and ready to use, all you have to do is add the generators.

    @Pierre-LucPineault, it does not appear those two conduits are on the same area of wall; Your outside image depicts a conduit approx. 2 units along, while your inside is approx. 5+ units along.

    @Timelord64 Both are on the same wall, the 2nd from the end near the junction with the 1st wall. Then on the inside they are linked in zig-zag towards the TV. Here's a pretty ugly top-down view, grey things being the conduits. Commented Jan 6, 2016 at 3:28

    @dube Not so much "Fallout being Fallout" as "Fallout 4 being a Bethesda product", I suspect.

I have the real answer you are looking for! I had your same question and I just stumbled on the answer. Go to power - conduits - wall pass through. Set one on each side of the wall, they should connect together noticeably. Hope this helped!


Many building pieces have small holes in them that can have wires strung through them or conduits placed in them in order to allow inside lighting. For example, take a look at one of the small metal walls you can build

enter image description here

The top right corner can have wire threaded through it or you can place an upside-down conduit inside it to link wire on both sides.

Many different wall segments allow this in places so experiment to find one that suits your build.

  • This more or less fits in with the curved roof solution I've been using. It will still require particularly special placement and tuning of the exterior and interior power links until you can line up the curved path of the cord between them so that it passes through the hole. Also, did you test this? I remember trying some of those walls before, without any luck even when I could a visibly clear line for the cable. Will give it another shot though.

You usually only need power conduits on the outside of your building. The power seems to be available inside a sphere or cube around that conduit automatically. So you don't need ugly cabling on the inside, just make sure there are some on the outside.

For example, when you scrap and rebuild the building to the right of the workshop building in Sanctuary, you only need two power conduits on the outside to power most of the building (I built a two-story building here, placed both conduits on the side facing away from the road on the "roof" line of the ground floor).
