The modern lighting junction box, or electrical box, is where the electrical wires originate. The junction box is where you will connect the wires to the cord set, and also where the ceiling canopy will attach to support the light fixture.
Should recessed lights be wired in series or parallel?
parallel
Wiring in series reduces the voltage of each light. For example, if you have four lights rated for 12 volts, they will need to be wired in parallel to receive the full 12 volts. But, if you have four lights rated for 3 volts, you can wire them in series and connect them to a 12-volt source.

Can you put a junction box behind drywall?
Junction box covers must remain accessible; they cannot be covered with drywall or other surface material. A junction box is most often used where an electrical circuit branches off in two or more directions from a location where an outlet or fixture is not practical.
When should a junction box be installed?
You’ll need a junction box if you can’t make the connections inside an existing electrical box. 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.
Can you extend electrical wire without junction box?
Short answer: NO. Long answer: All splices must be in a junction box, and the junction box must be accessible.
When would you use a junction box?
A junction box is an enclosure that protects a connection of two or more wires carrying electrical current. The use of junctions removes the need to run a wire from every outlet or switch back to the main service panel. This level of protection is needed to prevent fires and to maintain reliable connections.
Can I daisy-chain LED recessed lights?
Do you need a junction box for outside light?
Not all light fixtures require junction boxes because some have their own. When installing one of these fixtures, it’s okay to feed the wire straight into the terminal box, make connections and screw the box closed. When feeding a cable into a fixture box, it’s important to secure it with the clamp in the box.
How to replace a ceiling box with recessed lighting?
Use the template provided with your light kit to draw the outline for each opening.
How to convert a recessed light to a hanging light?
Turn off the electricity to the light-fixture circuit at the main electrical panel.
How to install a ceiling light without a junction box?
