Can electrical wires touch insulation?
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. However, under no circumstances should thermal insulation make contact with live uninsulated wires and cables.
Why can’t you cover a junction box?
Electrical wires run behind the walls and through the ceiling of your home, meeting at junction boxes. It is a safety hazard to completely bury a junction box in a wall.
Do junction boxes need to be secured?
Securing Cables
Article 334.30 states that cables coming out of the junction boxes should be secured within 12 inches of the box in all boxes equipped with cable clamps. These cable clamps are not to be removed. 314.17(C) states that cables must be secured to the receptacle box.
