As I have broken down a few simple steps for you. Be aware that you first have to initiate outdoor wiring lights in series. Adding an electrical outlet in the house would empower the association of the process.

Before working with any electricity inside your home, you must turn off the main power switch. Locate the circuit breaker to turn the main power.

Step 2: Connect The Wires

The process will teach you how to wire outdoor lights to a switch. In this step, locate the main switch to connect the wires. This will be done by feeding the wires through the holes inside the drywall.

Locate the attic inside to let the big cable run through the inner compartments. This is to make the wires connect with the cables. These are coming through the main switch.

Knowing how to install junction boxes for exterior light fixtures is vital in this context. The wires would connect the junction boxes for the power outlet to distribute electricity.

In general, you can ask what the 12/2 cable does for you.

The 12/2 cable would allow you to bring out the ground, neutral and hot wires. This will connect the light fixtures’ ground, neutral, and hotlines. This will further help to spread the cable to connect the main power outlets. Combining the three lines would help you light up the light fixture.

To make the cable spread through, connect them by hammering staples. This will prevent the wires from falling and spreading unevenly. This is on the wooden surface inside of the attic.

Step 3: Install The Junction Boxes

You will be installing two junction boxes on the exterior of the wall. Make sure that the cables have come out through the inside holes.

This is precisely where you will be installing the junction boxes. For this, you will know how to install outdoor light fixtures on brick.

You will also install a junction inside the attic where the cables are spreading. The process involves connecting light fixtures to a switch of the main outlet. You need to join the wires from the main electric outlet.

Also, you will be connecting the ground to the ground lines. You can make the connection by taping the wires accordingly.

After you are done, it is time to move on to the next step.

Step 4: Install The Light Fixtures

After working on the first three steps, the cables should come out of the main wall. This is through the holes of the exterior. This is where you will fix the junction boxes to install the light fixtures.

Wiring an outside light with a sensor will be explored here. However, you probably won’t need it to save time, effort, and cost. This is to ascertain how to install outside garage lights with no previous holes.

Locate the exterior surface to drill through the area; by doing that, you will connect the junction boxes that will fix the lighting.

The lighting system should be perfectly installed with proper screwing. You have to ensure the light switch and outlet have the same circuit. Make sure you seal the junction boxes with some caulking.

The sealed caulking needs to be made waterproof. Otherwise, there can be sparks.

In the process, the 12/2 cable would come out through the little hole in the box. It would help if you let the ground, hot and neutral lines come out.

The use of pliers and wrenches is beneficial here. This is to cut the wires to make them sharp. The exposed sharp ends of the wires would connect to the wires of the light fixtures.

Wiring an outside light to a plug is easier than you think. The back area of the light fixture should be detached now. This is to let the wires come out.

By connecting the three wires’ lines, you will seal the light. This is to attach the light fixtures to the junction box. On the inside, the wires are connected in the same method.

Step 5: Turn On Back The Main Power Switch

At the end of it all, you have to make some screwing of the light. This is into the wall. Make sure the screw is deep and robust.

After you are done, it is time to go to the main power switch.
