Are the junction boxes usually under the insulation or above it? (For the kind of insulation that comes in rolls and gets unrolled in the attic.)If the junction boxes are above the insulation, do the wires go through the insulation to get to the junction boxes?
1) Nail wood together to frame the house 2) Install heating and plumbing systems 3) Install wiring systems 4) Install insulation 5) Put up the wallboard The wiring is stapled to the sides of the wood. The insulation covers it. A junction box is an electrical box just used for splices no outlet or switch. A house usually starts off with zero junction boxes. If there are junction boxes in your attic, they are likely nailed to wooden members at least a foot above the insulation. That's so the next electrician can find them. The same is true for any crawl space you might have.
i always put them on top just in case it ever has to be serviced it can easily be found and the wires as well for better tracking ive seen some houses were they have all kinds of problems and the wires are buried somewhere under ducts and its just a pain so i save time next time and so will the next people
All junctions should be accessible from the habitable side of the wall. The wires are ussually run through holes drilled in the framing members, so to answer your question, the wires are probably embedded in the insulation (the insulation was packed around the wires)
The junction boxes and wiring go in first during the rough in, the insulation is added after. You can cut the insulation cotton candy with a razor and push it down. Most insulation has things that rats and squirrels do not like to eat. This means this deters critters from chewing the wires and starting a fire.
What is -Yes, under the insulation,its a building code law that it be done that way,fire precautions.
