It’s advisable to add a little extra length to your measurements to allow for any unforeseen circumstances or adjustments. Once you have the total length, you can cut your new wire to size. Having the correct length of wire from the outset will help streamline the rest of the installation process and ensure a more effective connection.
Step 3: Prepare the Wires
With the power turned off and the new wire cut to the required length, the next step is to prepare both the old and new wires for connection.
Use wire cutters/strippers to carefully strip approximately 1/2 inch (13 mm) of insulation from the ends of both the existing and new doorbell wires. Be sure to strip only the amount of insulation necessary to expose the metal conductors, taking care not to damage the wires themselves.
If the wires appear frayed or damaged at the ends, trim the damaged section before stripping again to ensure a clean, strong connection. Once the wires are stripped, you can move on to connecting the old and new wires together.
Properly preparing the wires is crucial as it ensures a reliable connection and promotes the longevity and efficiency of your doorbell system.
Step 4: Connect the Wires
Now it’s time to connect the old and new wires together. Take one end of the old wire and one end of the new wire and twist them tightly together in a clockwise direction. Once they are securely twisted, screw on a wire connector, making sure all exposed conductors are covered by the cap. Repeat this process for the other end of the wires.
If you’re working with more than two wires, use a larger sized wire nut or multiple smaller ones to ensure all connections are secure. You can also add electrical tape over the wire connectors for added protection and stability.
Step 5: Run Your New Wire
With your old and new wires now connected, carefully run your new wire from the old doorbell location to the new one. Take care not to damage or pinch the wires while running them, and ensure they are hidden or secured safely along the way. If you need to drill holes for the wire to pass through, make sure they are appropriately sized and located in a safe and suitable area.
You can also use cable clips or staples to secure the wire along walls or baseboards. It’s essential to keep the wire away from any potential hazards, such as sharp objects or water sources.
Step 6: Connect Your New Wire
Once your new wire is in place, strip off the insulation at both ends using your wire cutters/strippers, following the same process as before. Twist together each bare end of your new wire with its corresponding connection point at either end (old location/new location) and secure them with wire connectors.
Again, if there are multiple wires involved in this connection, use appropriate-sized wire nuts and secure with electrical tape if necessary.
Step 7: Check Your Connections
With all the wires connected and secured, it’s time to check your connections to ensure they are reliable and safe.
