Using a screwdriver: Insert into the slot, use as a pivot, and gently pull the wire out
It is important to note that you should always ensure that the power/breaker is off before attempting to release push-in electrical connectors, as you will be touching a live wire.
To release the wire using a screwdriver, first, locate the release slot. Most push-in connectors have a small rectangular release slot located beside the wire entry hole. This slot provides access to the internal spring mechanism that holds the wire in place.
Next, insert the screwdriver into the slot. Use a small flathead screwdriver and gently insert it into the release slot. Be careful not to apply excessive force, as the internal spring mechanism is delicate and can be damaged. You only need to insert the screwdriver deep enough to disengage the spring mechanism.
Now, use the screwdriver as a pivot and gently pull the wire out. With the screwdriver still inserted in the slot, use it as a pivot point, bringing the back end towards the wire to force the tab away from the wire. This will release the wire, allowing you to gently pull it out with your other hand.
If the wire feels stuck, ensure that the screwdriver is properly engaging the release mechanism and try again. It is important to be gentle and not force the wire, as this can damage the connector or the wire itself. Once the wire is removed, inspect it for any damage and trim or re-strip the insulation if necessary before reconnecting.

Twisting and pulling: For old/weak outlets, twist the wire back and forth while pulling
If you're dealing with an old or weak outlet, or a wire that hasn't been inserted deeply enough, you may be able to simply twist the wire back and forth while pulling to release the connection. This method doesn't require much force and can be done by hand. However, it's important to ensure that the power is turned off before attempting this, as you will be handling a live wire.
This twisting and pulling technique is a quick and straightforward way to release push-in electrical connectors. It is especially useful when dealing with older or weaker outlets where the wire may not have been securely fastened. By twisting and pulling, you can create enough leverage to release the wire without damaging the connector or the wire itself.
It is important to note that this method may not work for all types of connectors or outlets. Some connectors may have a release function, while others may require a different approach, such as using a screwdriver to push away the "tab" that holds the wire in place. Additionally, if the wire is deeply inserted into the connector, twisting and pulling may not be sufficient.
In some cases, it may be necessary to cut and re-strip the wires to release them from the connector. However, this method should be avoided if possible, as it can be time-consuming and may require the use of tools like needle-nose pliers to create a secure connection. It is always recommended to consult with a professional electrician if you are unsure about the best course of action.
Overall, the twisting and pulling method is a simple and effective technique for releasing push-in electrical connectors in old or weak outlets. By gently applying force and twisting the wire, you can safely release the connection without causing damage to the components.

Cutting wires: Cut and re-strip wires to release the connection
If you're working with electrical connectors, it's important to ensure that the power is turned off before you start. This is because you will be handling live wires, which can be dangerous if active.
Cutting and re-stripping wires is a way to release the connection of push-in electrical connectors. This method is useful if you don't want to reuse the wires. However, if you want to keep the wires intact, there are other methods you can try, such as using needle-nose pliers to twist and pull the wires out.
To cut and re-strip wires, start by using a cable ripper or a utility knife to remove the outer sheath of the wire, exposing the inner wires. Be careful not to cut too deep and damage the wires inside. Once the sheath is removed, use diagonal-cutting pliers to snip off the remaining sheath and any other separation materials.
Now, you need to strip the insulation from the ends of the wires. This can be done using a wire stripper, which is designed to cut to a specific depth without damaging the wire. Alternatively, you can use scissors, knives, or other sharp tools, but be very careful not to cut through the wire. Strip about 3/4 to 1 inch of insulation from each end, enough to ensure a clean connection without exposing too much of the wire.
After stripping, twist the wire ends together clockwise, then trim off any excess wire. Now, you can connect the wires by screwing on a wire nut or using compression sleeves for a more permanent bond. Make sure that no bare wires are exposed, and consider using electrician's tape for added security.
