Power Cord Kit Guide for InSinkErator Disposals
A garbage disposal power cord kit is one of the most overlooked accessories during installation. Many InSinkErator disposals—especially Badger and several Evolution models—do not include a factory-installed power cord. That leaves a lot of homeowners stuck mid-install, wondering why the disposal has bare wire leads instead of a plug.
A universal power cord kit solves that problem instantly. It provides a safe, grounded, pre-terminated cord you can attach directly to the disposal without cutting or stripping wall wiring. This is the recommended setup for anyone who wants a clean, plug-and-play installation without hiring an electrician.
In this micro-guide, we’ll cover when you need a power cord kit, which InSinkErator models require one, how to install it safely, what comes in the package, and how to choose the right length for your under-sink layout. We’ll also link you to our recommended universal cord kit that’s compatible with Badger, Power, and Evolution disposals.
What Is a Garbage Disposal Power Cord Kit?
A power cord kit converts a hard-wire-ready garbage disposal into a plug-in appliance. It includes a grounded electrical cord that attaches to the disposal’s wiring compartment using a strain-relief fitting and color-coded terminals.
Most garbage disposal power cord kits contain:
- 3-prong grounded power cord – usually 3–4 feet long.
- Strain-relief connector – keeps the cord from pulling loose.
- Wire connectors (wire nuts) – to join the internal wires safely.
- Installation instructions – a basic wiring diagram and steps.
Once installed, the disposal simply plugs into a standard 120V under-sink outlet, making future replacement or service much easier.
Do InSinkErator Disposals Come With a Power Cord?
Many InSinkErator disposals do not come with a pre-installed power cord. Instead, they ship with bare wire leads meant for either hardwiring into a switch-controlled circuit or connecting to a separate power cord kit.
Here’s a quick overview:
| InSinkErator Series | Power Cord Included? | Notes |
|---|---|---|
| Badger Series | Usually no | Most models are hard-wire ready and need a separate power cord kit. |
| Power Series | Mixed | Some models include a cord; others ship as hard-wire units. |
| Evolution Series | Usually no | Often designed for permanent wiring unless you add a cord kit. |
| Pro / Select Models | Usually no | Typically supplied as hard-wire disposals for contractor installs. |
Bottom line: If you’re buying a new InSinkErator disposal, assume you will need a power cord kit unless the listing clearly states “power cord included.”

Compatibility With InSinkErator Disposals
A universal garbage disposal power cord kit is designed to be compatible with all standard modern InSinkErator models, including:
- Badger Series
- Power Series
- Evolution Series
- Compact, Select, Prestige and similar models
The wiring layout is very consistent across these disposals. As long as your unit has:
- a black wire (hot),
- a white wire (neutral), and
- a green screw or wire (ground),
…then a standard 3-wire power cord kit will connect properly.

What Comes in a Power Cord Kit?
Most InSinkErator-compatible power cord kits provide everything you need to convert a hard-wire-ready disposal into a plug-in unit:
- 3-prong grounded cord – thick, insulated, and rated for disposal use.
- Strain-relief fitting – protects the internal wiring from being pulled loose.
- Wire nuts – to secure the hot, neutral, and ground connections.
- Mounting hardware – sometimes included, depending on the kit.
- Instructions – clear wiring diagram and safety guidelines.
This small accessory saves time, avoids cutting into house wiring, and makes replacement easier in the future.
How to Install a Power Cord Kit on an InSinkErator Disposal
Safety first: Make sure power is turned off at the breaker before working on any electrical connections.
1. Open the Wiring Compartment
Locate the small metal plate on the bottom of the disposal. Remove the screw and take off the cover to reveal the wiring compartment and color-coded wires.
2. Install the Strain-Relief Connector
Remove the appropriate knockout in the wiring compartment and insert the strain-relief connector. Tighten its screws so it grips firmly onto the metal housing.
3. Feed the Power Cord Through
Slide the end of the power cord through the strain-relief connector and pull about 6 inches of cable into the wiring chamber. Lightly tighten the strain relief so the cord stays in place.
4. Connect the Wires
Match the colors:
- Black cord wire to black disposal wire (hot).
- White cord wire to white disposal wire (neutral).
- Green cord wire to the green ground screw or wire inside the compartment.
Twist each pair of wires together and secure them using the provided wire nuts. Give each connection a gentle tug to ensure it is secure.
5. Close the Wiring Compartment
Tuck the wires neatly into the compartment, replace the cover plate, and tighten the screw. Fully tighten the strain-relief connector so the cord is firmly anchored.
6. Plug In and Test
Restore power at the breaker, plug the disposal into the outlet, run cold water, and briefly turn the wall switch on. If the unit runs smoothly without flickering or cutting out, your installation is successful.
Choosing the Right Power Cord Length
Most power cord kits for garbage disposals are around 3 feet long, which is suitable for the majority of under-sink installations. That length usually gives enough slack to reach the outlet while keeping the cord tidy.
You may want to look for a longer cord if:
- Your under-sink outlet is mounted higher on the wall.
- You have a double-bowl sink with the disposal placed farther from the outlet.
- Water filters, RO systems, or plumbing lines block the most direct path.
In most standard layouts, though, the supplied cord length in a universal kit is ideal.
When to Replace an Old Power Cord
Even if your current disposal already has a cord, it may be time for an upgrade. You should replace the power cord kit if you notice:
- Frayed or cracked insulation anywhere along the cable.
- Discoloration or heat marks near the plug or cord base.
- A plug that feels loose in the outlet or wobbles easily.
- Buzzing, flickering, or intermittent power when the cord is moved.
A fresh, UL-listed power cord is a small investment that removes a major electrical risk under the sink.
Which Power Cord Kit Should You Buy?
For InSinkErator disposals, the best option is a universal 3-prong power cord kit specifically rated for garbage disposal use. Look for:
- 3-conductor grounded plug (hot, neutral, ground).
- UL-listed or equivalent safety certification.
- Clear statement of compatibility with InSinkErator or standard disposals.
- Durable, moisture-resistant insulation suitable for under-sink environments.

Power Cord Kit FAQs
Do all InSinkErator disposals need a separate power cord kit?
No, some disposals come with a pre-installed power cord, but many do not. If your new disposal arrives with bare wire leads and no plug, you will need either a power cord kit or a hardwired electrical connection.
Is it better to use a power cord kit or hardwire the disposal?
For most homeowners, a power cord kit is the easier and safer option. It allows you to plug the unit into an outlet instead of opening up wall wiring. Hardwiring is usually best left to a licensed electrician.
Can I install a power cord kit myself?
Yes. Most DIYers can install a garbage disposal power cord kit using basic tools as long as the power is turned off at the breaker and the wiring instructions are followed carefully. If you are unsure, consult an electrician.
Are disposal power cords universal?
Most 3-prong disposal power cord kits are designed to be universal for standard 120V garbage disposals and work well with modern InSinkErator models. Always confirm compatibility in the product description before buying.
Should I replace the power cord when I replace the disposal?
Yes, it’s a good idea. A new disposal deserves a fresh, properly rated power cord. Reusing an old, worn cord can create unnecessary safety risks under the sink.
