How to Wire a Neutral Safety Switch
The safety switch is a device that will shut down the electric current of an electrical circuit if it detects any irregularities. The electrician who installs your home’s wiring and equipment must connect the wires and devices in such a way that, should anything go wrong with them, they will not let electricity flow to those areas closest to you.
This is done by installing neutral switches along the circuit path. If the power goes through those circuits due to malfunctioning equipment or bad wiring, this switch shuts off all current to not harm anyone nearby. If you want to know more about how to wire a neutral safety switch, then read on!
Step by Step Guide: How to Wire a Neutral Safety Switch
To wire a neutral safety switch, you will need these tools: A pair of pliers, a screwdriver, a drill or pointed power drill bit, and a ladder. You will also need an extension cord if you do not have an outlet within reach of where the switch will be installed.
You will remove the switch plate to get access to the wire where it is connected inside your outlet. Therefore, it is best to ensure the power is turned off before working with anything in or around outlets. There are two ways to do this, and one involves turning the light switch on and off while checking for lights that are still active after shutting off the switch. The other way is to plug something else into the outlet; if it turns on, the power is off.
Use the screwdriver and the pliers to take off the switch plate. The screws should be facing you, and there will usually be two or three on the bottom of the plate. Use the pliers to turn them out, pulling up at an angle counterclockwise.
Unscrew any other wires that are connected to the outlet, as well as any caps that are covering them. This will be important to get access to the wires that you need to run into your switch.
Look at where one of the prongs on the outlet is connected, and drill a small hole through this side of it. Make sure it is where one of the wires inside is not connected to one of the screws. Use caution, as this can be somewhat dangerous depending on how worn down your switch is.
Run the wire through the hole you drilled, and tie it with a twist or small piece of string to keep it in place. Make sure that all of the exposed wirings are covered with electrical tape to prevent any short circuits.
Use the screwdriver to take off all of the screws holding your switch in place, and pull it out carefully. Look at how it is shaped inside, and you might need to cut a small notch for the wire you will be adding in.
Connect your wire to the prong that is not connected inside. If one looks loose, tighten it before continuing and make sure all wires are covered in electrical tape. Then screw it back into place and put on a new switch plate if you have one.
Things to Consider When Wiring a Neutral Safety Switch
When wiring a neutral safety switch, you need to follow some rules. Without these rules, the device will not work correctly and might even cause a fire in your house. So be sure to read and understand these things before starting:
1. A Neutral Safety Switch Must Be Smart:
You might not think of it as such, but an excellent neutral safety switch uses some digital electronics to allow it to ‘think’ for itself. It is the only way the circuit can know how to respond when you flip on or off your lights and other devices. So you want one that has all of the features that can learn and self-adjust to your house’s electrical needs.
2. Only Use a Safety Switch When the Circuit Is Not in Use:
When you have a power circuit disabled by a switch or fuse, it must be isolated from the main power grid. If you do not follow this rule, it could result in a dangerous short circuit. You should never leave your house with any breaker or fuse turned off. Even when you are not using the circuit, make sure it is covered by the switch to avoid an accident.
3. Use Outdoor-rated Wire for Your Power Connections:
When you are wiring up the neutral safety switch, ensure that all links are adequately insulated to prevent any danger of electrical shock. If you do not want it exposed during use, be sure to seal the wires in a plastic conduit.
4. Use Adequate Screw Terminals for Your Connectors:
You do not want any bare wire touching or exposed when using a neutral safety switch. It will allow current to pass through the body and cause a shock. Be sure to use only heavy screw terminals so that you can securely fasten each wire to prevent any accidental connection.
5. The Neutral Safety Switch Must Be Adequately Grounded:
Your electrician should always include a wire run from your neutral safety switch to a good ground source. If this is not done, the whole system will not work and could even cause a fire if the wires come in contact with each other.
6. Never Leave or Cover Your Neutral Safety Switch When It Is Disconnected:
Until you get around to installing your new neutral safety switch, be sure that all of its wiring connections are accessible and easy to access. If you wire up the neutral safety switch and then place a cover over it, the whole system will not work.
7.Never Put Your Neutral Safety Switch on a Circuit With High Voltage:
You should avoid wiring up your new neutral safety switch to any circuits that have more than 120 volts of electricity running through them. If you need to do so, use an isolation transformer to keep the voltage below 120 and prevent accidents.
You have successfully wired your neutral safety switch. It is important to remember that the new wires should be secured with electrical tape and not clipped, but there are many other ways you can ensure them, depending on your preferences.
