Whether you’re a DIY-er or an experienced plumber, it’s important to know what you need to install a garbage disposal. In this blog, we discuss the materials and tools needed to install a garbage disposal, how to wire it, whether you should hardwire it, and when to call a professional. So how to wire garbage disposal?
What Do I Need to Install a Garbage Disposal?
You’ll need the following materials and tools to install a garbage disposal: a screwdriver, a wiring compartment, a wire stripper, pliers, a wire nut, a clamp, a mounting ring, a strain relief, a new garbage disposal unit, a dishwasher hose, a power cord, and electrical tape. Additionally, you may need a putty knife and a plumber’s putty if you’re replacing an old disposal unit.
When installing a garbage disposal, you will need a flange to secure it to the sink. It’s important to make sure the flange is properly plumbed to avoid leaks. A pair of pliers can help tighten the connections. Before installing the disposal, turn off the breaker to the electrical circuit. You will need to attach the sink flange to the drain line and connect the red wire to the cord wire. The disposal unit is secured to the sink flange using a snap ring. To install the snap ring, you can use a screwdriver. It’s recommended to install a GFRC circuit for the garbage disposal for added safety. If you’re unsure about the wiring or installation process, it’s best to call a professional.
Before installing the garbage disposal, make sure you have a dedicated circuit and a wall outlet close to the location of the unit. Using the wiring compartment, connect the white wire from the disposal to the white wire from the wall outlet. Secure the connection with a wire nut. After installing the mounting ring and attaching the strain relief, place the cover plate over the wiring compartment. Before plugging in the disposal, double-check that the appliance cord is connected to the unit. Finally, plug in the disposal to the outlet under the sink.
Instructions on How to Wire Garbage Disposal
To wire your garbage disposal, start by connecting the new disposal unit to the mounting ring with a screwdriver. Then, connect the power cord to the wiring compartment and secure the wire to the wall with a clamp. Next, connect the black wire lead to the black wire and the white wire lead to the white wire. Use a wire stripper to remove the insulation from the end of the wire and twist the exposed copper wire around the screws on the wiring compartment. Finally, connect the ground wire to the ground screw.
Use a screwdriver to tighten the connection of the power cord to the wiring compartment and secure it with the clamp. Make sure to insert the cord into the wiring compartment before tightening. If the electrical outlet near the disposal is not a GFCI, it’s recommended to install a new one to prevent electrical shocks. Before connecting the wires, turn off the circuit breaker to the disposal to ensure safety. After connecting the black and white wires, attach the ground wire to the green screw on the wiring compartment. You can also use a plumbers putty to putty around the edges of the disposal to ensure a tight seal. To turn on the disposal, simply flip the wall switch. If the wire leads are stranded copper, use the wire stripper to remove the insulation and twist the exposed wire around the screws.
How Do I Hardwire My Garbage Disposal?
You can hardwire a garbage disposal by connecting the black and white wires to the corresponding wires in the electrical box. You’ll also need to connect the ground wire to the metal box and secure the cord clamp to the disposal unit. If you’re not comfortable wiring your garbage disposal, it’s best to call a professional.
To ensure a safe and secure connection, use notches on the wire stripper to strip the insulation on the black, white, and ground wires. The solid copper wire should then be connected to the corresponding wires in the electrical box. The end of the clamp should be securely fastened to the metal box to ensure a stable connection.
The ridges in the wire stripper are meant to identify the hot wire, which is the black one in most garbage disposal wiring setups. Depending on the types of garbage disposals, there may be slight variations in the wiring process, so it is best to consult the manufacturer’s instructions before starting. Read here do you have to take labels off when recycling.
Should I Hardwire My Garbage Disposal?
Whether you should hardwire your garbage disposal depends on the type of disposal unit you have. If your garbage disposal comes with a power cord, it’s best to just plug it in. However, if it doesn’t come with a cord, you will need to hardwire it.
The types of garbage disposals available in the market vary and can have different installation methods. If your disposal unit comes with a power cord, it can be simply plugged into an electrical outlet without any need for hardwiring. However, if the disposal unit doesn’t have a cord, you’ll have to hardwire it. In this case, the cable clamp should be fitted into the hole at the bottom of the disposal unit and secured using a screw with a screwdriver. The threaded end of the clamp should be inserted into the hole and tightened with a nut. This will secure the cable and prevent it from getting disconnected during use.
Do All Garbage Disposals Need a Power Cord?
No, not all garbage disposals need a power cord. Some disposals are designed to be hardwired and do not come with a power cord. If your disposal has a cord, it’s best to plug it in rather than hardwire it.
To install disposal with a cord, first, prepare the appliance cord wires by locating the end of the cord. Connect the red wire lead to the corresponding wire in the wiring compartment. Carefully tuck the other wires into the wiring compartment as well. Once everything is securely in place, flip the switch to turn on the disposal.
How Should a Garbage Disposal Be Plumbed?
When you’re plumbing your garbage disposal, the first step is to install the mounting ring. Then, use a putty knife and a plumber’s putty to seal the area around the mounting ring. Next, attach the disposal unit to the mounting ring with screws and connect the dishwasher hose to the discharge tube. Finally, connect the plumbing connections to the sink and plug in the power cord.
After you have installed the mounting ring and sealed it with putty, you should connect the disposal unit to the mounting ring with screws. Then, connect the dishwasher hose to the discharge tube. Next, you should connect the plumbing connections to the sink and make sure that the electrical power is properly connected. To secure the electrical connections, place a nut onto the clamp and tighten the ground screw. Ensure that the wires inside the unit are properly connected and that copper of the same nominal size is used. Finally, plug in the power cord to complete the installation.
When to Call a Professional?
It’s best to call a professional if you’re unsure about wiring your garbage disposal. An electrician can help you properly wire the disposal and ensure the electrical components are up to code.
The Process for Wiring a Switched Garbage Disposal with an Optional Dishwasher
If you’re wiring a switched garbage disposal with an optional dishwasher, you’ll need to connect three insulated wires to the wiring compartment. The black wire is the hot wire, the white wire is the neutral wire, and the green wire is the ground wire. Use a wire stripper to remove the insulation from the end of the wires and twist the exposed copper wire around the screws on the wiring compartment. Finally, connect the ground wire to the ground screw.
Tips
When wiring your disposal, be sure to tighten the wire nuts and use electrical tape to secure the wire connections. It’s also important to make sure the strain relief is securely attached to the bottom of the disposal.

- When installing the disposal, make sure to attach the strain relief securely to the bottom.
- Clamp the wires into the wiring to ensure they don’t come loose.
- If the disposal may move, secure it with a clamp and into the wiring.
