Is It Ok To Have A Junction Box In The Attic? Codes require that boxes in attics be permanently accessible. While building codes usually allow junction boxes in attic, the codes impose installation standards to prevent electrical fires and accidental shock.
You can't conceal junction boxes in ceilings, walls or non-accessible attics and under-floor areas. In addition, they should not be placed in areas where flammable gases, vapors or dust are present in an amount that could result in a fire or explosion.
Is it safe to put a plastic junction box in the attic? Your local electrical code may allow you to place a junction box in the attic. Check with the permitting office before you do this. Metal boxes are stronger, so they will resist damage better than plastic boxes.
junction boxes are not allowed to be hidden in the walls or ceilings. they must be accessable. Therefore, the juction boxes are usually in the attic or basement/crawlspace areas. How was your dishwasher connected, plugin to an outlet or hardwire?
NEC314.
Section 314.28 of the National Electrical Code indicates the set of standards for the materials that are utilized for making junction boxes. The materials used must be non-combustible. Examples of these materials are plastic and metals.
A junction box should always surround the spot where wires join together, and it should always be covered.
These have criss-cross yellow lines painted on the road. You MUST NOT enter the box until your exit road or lane is clear. However, you may enter the box and wait when you want to turn right, and are only stopped from doing so by oncoming traffic, or by other vehicles waiting to turn right.
Choose a location for your junction box that is easily accessible and complies with local electrical codes. The box should be mounted securely to a stud or joist, with its face flush to the wall surface. For exterior installations, select a location that provides protection from direct exposure to the elements.
Never install a junction box in a concealed wall or ceiling space where it cannot be accessed in the future. Junction boxes must also be covered with solid covers.
A junction box is not always necessary if the electrical wires are tucked away. That means the wires are in a conduit and behind the drywall or not exposed.
Anything that's safe to store in these rooms should still be put away in an airtight plastic container with a lid to keep environmental elements out. Cardboard boxes will deteriorate due to heat and water, and animals and bugs will snack on them or possibly use them for nesting materials in the meantime.
For example, if you have a light fixture that doesn't need a box for mounting, but the wiring connections are not protected by some kind of cover, then you cannot use the fixture without a junction box. If a fixture meets all of the criteria of a box but lacks a cable clamp, don't use it without a box.
Junction Boxes with Missing Covers
If easily combustible materials, such as paper or cardboard, are stored near unprotected energized wiring, a spark or electrical arc could easily start a fire. Figures 1 and 2 are examples of junction boxes with exposed wiring.
Per their requirements, electrical boxes must be covered with matching electrical box covers. You can't cover them with drywall, paneling or other wall coverings. The box also needs to have enough space for the conductors inside.
(c) Each outlet or junction box must have a cover unless a fixture canopy, switch cover, receptacle cover, or other cover is used.
Wherever you have an electrical connection, that connection needs to be enclosed and protected. Anywhere you have wires spliced together, you need a junction box. Building codes require this protection because contact between wires can cause a spark. That's dangerous.
Flexible cords must not be concealed by walls, floors, or ceilings, or located above suspended or dropped ceilings [400.8(5)]. Receptacles are permitted above a suspended ceiling, but a flexible cord is not.

You cannot cover any junction box that still has live wires in it. Your best bet is to either remove the box all together or just put a cover plate on it.
You cannot conceal junction boxes, ever. They must always be left accessible. When doing new construction electrical work, wiring should be planned so that no junction boxes are necessary.
Junction boxes are one of the most integral components of any electrical system. If you are an electrician, you might know the ins and outs of junction boxes. An electrical junction box accomplishes many great things regarding electrical wiring.
There's no limit to the number of junctions that you can have. They must be left accessible.
As standard junction boxes have no cable clamps this means the box must be screwed down and the cables fixed to prevent strain on the connections. Care must be taken with the connectors particularly with stranded cables to ensure all the strands are clamped in the connector.
Properly installed lighting junction boxes are essential for the safety of the home and its occupants. Faulty or poorly installed boxes can lead to electrical fires or electrocution. Additionally, they can also lead to power outages or damage to electrical appliances.
