Introduction
In this article, we will guide you through the process of installing rough end electrical in a new construction house. From wiring outlets to mounting ceiling fans, we will cover everything you need to know. So, let's get started!
Installing Electrical Outlets
Before we dive into the details, let's discuss the different steps involved in installing electrical outlets.
Choosing Circuit Breakers
One of the first things to consider when wiring your own house is the circuit breaker panel. Each bedroom should have its own circuit, meaning it should have a dedicated breaker and home run to the panel box. This allows you to easily control the power supply to each bedroom.
Pros:
- Easy control of power supply for individual rooms.
Cons:
- Requires additional circuit breakers and wiring.
Installing Switch Boxes
To start the installation process, begin by putting up the switch box. The switch box will be used for the ceiling fan and light, as well as where the power comes in. For this, use a two-gang box, which provides space for two switches. The height at which the switches should be set is subjective, but a common practice is to mark four feet on the stud and position the switch box at the top. The flanges on the box ensure that the drywall will be flush, and you can secure it with nails.
Pros:
- Easy installation of switches for controlling lights and fans.
Cons:
- Subjective positioning of switch box height.
Running Electrical Wire
Now it's time to run the electrical wire. We will be using 12-3 wire, which consists of three 12-gauge wires in one bundle. Start by drilling a hole through the wall plate and run the wire up to the ceiling fan mount using a saddle box. The saddle box is a great invention that securely mounts ceiling fans to rafters or floor joists, effortlessly bearing the weight.
Pros:
- Secure mounting of ceiling fans and light fixtures.
- Easy routing of electrical wires.
Cons:
- Requires drilling through walls.
Mounting Ceiling Fan
Once the saddle box is in place, it's time to mount the ceiling fan. Find the center of the room and mount the saddle box accordingly. After securing the saddle box with screws, reinstall the center screw to hold the weight. The lag bolts will be used later to securely mount the ceiling fan after the drywall is up.
Pros:
- Stable mounting of ceiling fans.
- Easy installation process.
Cons:
- Requires precise centering of the box.
Wiring the Ceiling Fan
To provide power to the ceiling fan, run the 12-3 wire from the switch box to the saddle box. Drill a hole through the stud and staple the wire along the way. Make sure to separate the wires and strip them using wire strippers. Use copper crimp sleeves to tie the ground wires together and label the wires for easy identification in later stages.
Pros:
- Efficient distribution of power to the ceiling fan.
- Clear identification of wires.
Cons:
- Requires wire stripping and labeling.
Arranging Electrical Boxes
Now that the ceiling fan is wired, it's time to arrange the electrical boxes for the outlets in the room.
Understanding the 6-12 Rule
When spacing electrical outlets on a wall, it's important to follow the 6-12 rule. This rule states that there should be a maximum distance of 12 feet between outlets, and outlets should be placed at least 6 feet away from doors. Additionally, any wall segment longer than 2 feet should have a receptacle. By following this rule, you can ensure that the electrical outlets are spaced properly for convenience and safety.
Pros:
- Adherence to safety and building code regulations.
- Convenient placement of electrical outlets.
Cons:
- Requires careful calculation and measurement.
Installing Receptacle Boxes
To comply with the 6-12 rule, measure 18 inches from the floor and mark the location of each receptacle. Install the receptacle boxes next to the marks, ensuring that the top of the box aligns with the mark. Secure the boxes in place by driving nails into the flanges. To connect the outlets together, drill holes through the studs and run the electrical wire from one box to another. Use wire staples to secure the wire at appropriate intervals.
Pros:
- Proper spacing and installation of receptacle boxes.
- Secure wiring connections between outlets.
Cons:
- Requires careful measurement and installation.
Connecting Wires
With the receptacle boxes in place, it's time to connect the wires.
Stripping and Crimping Wires
Use wire strippers to remove the sheathing from the wires and separate the wires according to their functions. Strip the wire ends and utilize copper crimp sleeves to connect the ground wires together. Ensure a tight crimp by using pliers. Finally, bend the excess copper wire to the side for neatness.
Pros:
- Neat and secure connection of ground wires.
- Easy stripping and crimping process.
Cons:
- Requires proper technique and tools.
Labeling Wires
To avoid confusion during the later stages of installation, label the wires according to their purpose. Use adhesive labels or markers to identify the power supply, fan and light combo, and receptacle wires. This will simplify the process and make it easier to connect the wires correctly.
Pros:
- Clear identification of wires for ease of installation.
- Minimizes the chances of mistakes during wiring connections.
Cons:
- Requires additional labeling step.
Final Walkthrough
Before concluding the installation, perform a final walkthrough to ensure everything is in order.
Power Distribution
Confirm that the power supply is correctly routed to the switch box, ceiling fan, and light combo. Additionally, ensure that the power from the switch box is properly distributed to all the receptacles in the room.
Pros:
- Efficient distribution of power to all required areas.
- Ensures that all electrical components are properly connected.
Cons:
- Requires thorough inspection of the entire electrical system.
Completing Installation
With all the wiring and connections complete, secure the wires in the boxes. Note that the panel box cover may be missing in the illustrations, but this will be addressed in a separate video on panel box installation. Once the drywall is hung, the final connections can be made.
Pros:
- Safely securing the wires in preparation for later stages.
- Readying the installation for the next steps.
Cons:
- Additional steps required for the final stages.
