How to Install a Motion Sensor Porch Light

The motion sensor porch light is not only good for security, but it is also a very convenient thing to have. It can also save you money on your electricity bills since you don’t have to leave a light on until you get back home. A reliable motion sensor light will automatically come on when you approach the porch, and is a nice welcoming home. It can also deter potential thieves and any other unwanted guests. Wiring one up on your own is not a particularly complicated job providing you have the kit and the right tools at your disposal. Remember, it is very important to connect the correct wires as you can quickly cause damage or injury.

Tools and Materials Needed:

  • Wire connectors
  • Screwdrivers set
  • Electrical current tester

Step 1 – Preparations

Before working with any electrical installation in your home, it is essential to turn off the mains power supply. You will find a circuit breaker in the main electrical panel in your home. Turn of the power to the appropriate section of the house, though if in doubt, turn off the main circuit breaker to disconnect all electrical supply to the house until you have completed the job. To verify that the circuit is switched off, use an electrical current tester as directed by the manufacturer of the device.

Step 2 – Assemble Lighting Fixture

The new porch light will likely come in various component parts which needs to be assembled. There should be a diagram instructing you how to do this.

Step 3 – Attach Crossbar

Assuming you already have an exterior lighting junction box in place, attach the crossbar which came with the light onto this. The crossbar will be a flat part of metal about 4 inches long. This should be attached to the junction box using provided screws and the mounting hardware included with the package.

Step 4 – Wire Porch Light

Attach the porch light to the power supply wires inside the electrical box. There will be a black wire, a white wire and the copper ground wire all connecting to the circuit breaker panel. The two black wires need to be connected together, with one for the lighting fixture and one coming from the junction box. Twist a wire connector onto both of the wires in order to connect them. The white wires also need to be connected in the same way. The ground wire will need to be connected from the lighting fixture to the bare copper wire coming at a junction box. Again, use a wire connector to connect these together.

Step 5 – Place Wires in Junction Box

When the wires are securely connected to each other, carefully push the wiring into the electrical junction box. Following the manufacturer’s instructions, attach the lighting fixture to the wall and make sure that all of the wires are properly enclosed. When you have completely finished the installation, and tightened all the screws, turn the electricity back on and press the switch to see if it works.
