Do junction boxes need to be exposed?
A: It is important to cover an electrical junction box no matter where it's located. When one or more electrical wires are twisted together, the connection causes resistance to the flow of electricity, which in turn creates heat.
What is code for electrical junction box?

What happens if you cover a junction box?
Yes, it is possible that you made a rather tight connection and that it will never go bad but because the wires tend to run hot when heavier loads are applied (or simply during the summer season), they present a fire hazard, to say the least. So, the best option you have is to not cover junction boxes.
Where should a junction box be placed?
Installing Junction Boxes You should install the box with the opening facing out from the wall so all the wires inside are accessible. Like any electrical box, it should be installed so that the edge of the opening is flush with the wall. Screw the cover on with machine screws so you can remove it easily.
Can you put electrical junction boxes in the attic?

Why are electricians important?
Electricians have a role to play in raising awareness of the issue amongst other trades, and ensuring that their own installations can be accessed wherever possible in case the work, for whatever reason, has to be revisited in the future.
What is BS 7671?
BS 7671 states that “a junction box with screw terminals must be accessible” so that connections can be available for inspection, testing and maintenance. However, the standard doesn’t actually define exactly what is meant by “accessible”, leaving the interpretation of the word somewhat open to debate. Stipulating that connections should be ...
Why do electrical connections need to be in a box?
The electrical code requires you to keep the connections out of a junction box when you splice wires. It protects people from getting shocked by live wires and also prevents fires when the wires are overheated.
Can you install a light fixture without a box?
The junction box is a code requirement that was put in place to prevent fires and electrical accidents. Even though there is no junction box at the spot where you want to install the light, it doesn’t mean you can’t do it.
Do low voltage connections need to be in a box?
There are two answers to this question. It can be a good idea if it’s required. I’d prefer them to be in conduit, with the exception of the ENT/smurf tube. Similar to electrical wires, it will protect them from damage and provide accessibility.
