If you’re wondering how you install a light fixture without an electrical box, the short answer is that you don’t. The electrical box, or junction box, is a code requirement that was established to prevent fires and other electrical accidents.
What kind of box do you use for outdoor lighting?
Metal and Plastic Electrical Boxes
Weatherproof metal boxes for outdoor use are generally made of aluminum. If you are using metal conduit to run wiring to the electrical box, then a metal box is required—both to anchor the conduit and because the conduit and metal box system itself may be used to ground the system.
Do outside lights need to be on their own circuit?
Ideally, outdoor lights should be on a separate circuit – that way, if something goes wrong, they don’t trip the indoor lighting too. They don’t have to be on a separate circuit, but you have to properly insulate the circuit to protect it from the weather.
Can I use an outlet box as a junction box?
Yes. For code-compliance purposes: Each 14 gauge wire is 2 cubic inches, each 12 gauge 2.25. All of the ground wires count as a largest wire.
Is junction box necessary?
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 I use a light fixture as a junction box?
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 can’t use the fixture without a junction box. Or, if a fixture meets all of the criteria of a box but lacks a cable clamp, don’t use it without a box.
How do you rewire an outdoor light fixture?
Step 1: Remove Existing Light. Before you begin any project dealing with electricity, you MUST disconnect the power at your main circuit breaker panel or fuse box. Step 2: Replace the Mounting Bracket. A new light fixture should come with mounting hardware. Step 3: Wire the Outdoor Light. Step 4: Install the New Fixture.
