The box can be mounted anywhere inside theroom — on the ceiling or on the walls. When the location hasbeen set, run the wires to meet in that location. Use adrill in case the wires need to run through walls.
Hereof, are junction boxes allowed?
You are on the right track. Junction boxes, withblank covers are allowed above a suspended ceiling as it isnot considered a closed space. The wires that are loose andwirenuted need to be put in a j-box. Also, clamps need to beused at each wire going into a j-box.
Likewise, people ask, can I cover a junction box with drywall?
As long as there are no wires inside the box, youcan cover it with drywall. If the box is stillacting as a junction box, however, and wires are joinedinside it, the electrical code mandates a removablecover. Covers come in plastic or metal, and youattach them with machine screws.
Some areas might allow for junction boxes thatdon't penetrate ceiling drywall. In this case, the boxeswill open into the attic; occasionally they're uncovered.Since insulation is combustible, you must install faceplates on all attic junction boxes to prevent contactbetween bare wires and insulation materials.
