Once the connection is secure, make sure to wrap it with electrical tape or a cap or nut to protect it from coming loose. 

It’s important to follow safety guidelines when connecting any electrical wires and make sure all connections are tight and secure before turning on any power source.

Step 6: Tighten The Screw

Once all the wires are connected and secured with their respective wire nuts, it’s time to tighten the screws. 

In Step 6, use an appropriate sized screwdriver to securely tighten the screws on the junction box. 

Make sure that all the screws are tight enough to keep the wires secure and prevent them from coming loose. 

Once all screws are tightened, you can proceed to Step 7 which is wrapping the wire with a cap or nut.

Step 7: Wrap The Wire With Cap Or Nut

Once all of the wires are connected, it’s time to secure them. 

For this step, you will need a wire cap or nut. 

These are used to cover the splices and protect them from damage. 

Depending on the type of junction box you are using, you may need to use a different connector.
