As long as you don’t pinch the wires between the joists and floorboard you should be OK. You don’t want to lay the wood floor directly on top of any wire or cables.
Can electrical wires be covered with insulation?
Yes, you absolutely can. You can lay insulation around the junction boxes as well. Making sure that the insulation is of a fiberglass material will not only ensure a fireproof setup but also reduce airflow from the home through the attic.
Can you run wires under the floor?
Running electrical wires between the subfloor and the surface layer of flooring is not safe, but you can run them under the subfloor itself. To do this, you will need to make holes in the subfloor, and the best place to do this is through the bottom plates of walls.
How can I hide the wires in my attic?
Quote from Youtube video: Um. This is an insulated wall and it's kind of hard to get this thing up there. So sometimes you have to put it on a drill. Bit. And twist it backwards.
Does wire go over or under insulation?
Wiring should be installed before any insulation. When building a home, everything needs to be done in the correct order. For instance, after the framing is complete and the exterior walls have been put up, you need to consider the inside of the wall cavities before you drywall the interior.
Can attic insulation touch electrical wires?
Can insulation touch electrical wires in your home? It is perfectly safe for household insulation to touch wires provided the wires or cables are electrically insulated. There also are techniques to make insulation fit better around wires.
Does electrical wire in attic need to be in conduit?
No, conduit is NOT required in attics. Not unless conduit is required in your area. There are other factors involved in wiring in attic spaces, but your question is a bit too vague to go into that.
How do I run electric cables under floorboards?
Take floorboards (small sections between joists) up in between the holes to guide the cable. Brake cable outer feed through then attach cable and pull. Through hey presto job done ! End of thread job done !
How do you run electrical wires between floors?
Drill destination hole in floor. Run wire through hole. Feed the wire through the back of the outlet box, insert the box in the wall, and mount it in place. Strip the wires and attach them to the wall jack or run them to the device.
Can you run electrical wire under floor joists?
Code says that you may not staple wires to the bottom of a floor joist unless the wire is 6-2, 8-3, or larger. Smaller wires must be run through bored holes or be attached to a running board.
Can Romex be covered by insulation?
Romex can be installed above or under the insulation. It is OK to touch the outer jacket with your bare hands provided the insulation is not damaged. A good rule of thumb when working with electricity is to wear insulated (rubber sole) shoes and to always keep one hand in your pocket.
Can junction box be in attic?
Yes, junction boxes in attics, suspended ceilings and crawl spaces are legal. Basically, the rule is that ALL wire connections must be accessible. In other words, you can’t cut a hole in a wall or ceiling and bury a junction box by covering it with drywall, paneling, tile, or whatever.
Can you put fiberglass insulation over electrical wires?
Never mash fiberglass batts to fit under or around a pipe or electrical cable. Compressed fiberglass loses its R-value because its dead-air space is drastically reduced.
Can you put expanding foam around wires?
You have to consider if using foam is safe if you have anything routed inside the cavity, such as electrical wiring. So, if you were wondering whether expanding foam damages wiring the answer is yes. Expanding spray foam without carefully planning can damage electrical wiring.
Can you spray foam around electrical wires?
While there may be debate between individual contractors about spraying foam insulation over electrical wires, industry guidelines state that spray foam insulation can be applied directly over electrical wiring.
Can you use great stuff around electrical wires?
Never allow foam to touch exposed wiring. Wipe away imperfections with a cloth soaked in Great Stuff™ Foam Cleaner. Foam should be tack-free in 10 to 15 minutes. Store or dispose of the product as per directed on label.
Can I put filler over cables?
As others have said, its a bodge, and potentially dangerous. Over time the filler will corrode the copper making the join unsafe. The best remedy would be to pull in (or chase in) a new cable to a point where it can be safely joined as joins cemented into the walls are far from ideal.
Can expanding foam catch fire?
The propellant gas used to dispense the foam (methylene-diphenyl-diisocyanate 4,4) is highly flammable. The gas is emitted from the foam as it expands and dries out. It is heavier than air, sinks and forms an invisible cloud. If an ignition source is present, the gas can catch fire, potentially with explosive force.
Is Great Stuff foam flammable after it dries?
6. Cured foam is combustible and will burn if exposed to temperatures above 240°F (116°C). Do not apply GREAT STUFF™ foam around heaters, high heat lamps or recessed lighting fixtures, radiators, furnaces or fireplaces where it could contact heat conducting surfaces.
What insulation is fireproof?
Fiberglass insulation
Fiberglass insulation is made of glass combined with plastic polymers and is naturally fire-resistant.
