When Does Your Range Hood Need A Dedicated Circuit?

Most range hoods don’t need a dedicated circuit, but in certain situations, it’s the safer and more reliable choice. You may need a separate circuit if:

  • Your range hood has a high-powered motor or features like built-in heating or variable fan speeds
  • It’s combined with another appliance, such as an over-the-range microwave
  • Local electrical codes require fixed appliances like range hoods to have their own circuit

 Always check your local electrical code or have a licensed electrician inspect it.

Range Hood Power Requirements: What You’ll Need

Before deciding on a dedicated circuit, it helps to understand how much power your range hood actually uses. From wattage to breaker size, your electrical setup should match the type and power of the hood you plan to install.

Wattage & Amperage for Range Hoods

Most range hoods operate on 120V and draw between 1.5 to 4 amps. Larger or more advanced models will use more power. Use the table below as a quick reference:

Range Hood Type Typical Wattage Typical Amperage (120V)
Under-cabinet (basic) 150–300 watts 1.25–2.5 amps
Wall-mounted (mid-range) 250–400 watts 2–3.3 amps
High-performance models 400–700+ watts 3.3–6 amps
Range hood + microwave 800–1500 watts 6.6–12.5 amps

  • Ducted range hoods vent air outside and typically use more powerful fans to improve air suction. This can result in higher energy usage and a greater demand on your circuit.
  • Ductless range hoods filter and recirculate air inside the kitchen. These models generally consume less electricity, but may be less effective at removing heavy smoke or grease.

Breaker size depends on the electrical load of your range hood, but here’s a general rule of thumb:

  • 15-amp breaker: Suitable for standard range hoods under 400 watts
  • 20-amp breaker: Recommended for high-powered range hoods or combination units like hood/microwave combos

Always check the manufacturer’s specs, and make sure the breaker matches the wire gauge and total circuit load. If you're unsure, a licensed electrician can confirm the best fit for your home.

Risks of Not Using a Dedicated Circuit

Skipping a dedicated circuit for your range hood might seem convenient, but it can create serious electrical issues over time. Common risks include:

  • Tripped breakers: Too many appliances on the same line can overload the circuit and cut power.
  • Poor performance: If your range hood shares a circuit with other kitchen appliances, it may not receive full power.
  • Overheating wires: An overloaded circuit can cause wires to overheat, creating a fire hazard.
  • Code violations: If your installation doesn’t follow electrical code requirements, it could fail inspection or affect your home insurance.

Hardwired vs. Plug-In Range Hoods: Power Needs

Whether your range hood is hardwired or plug-in can determine whether it needs a dedicated circuit. Here's how the two options compare:

Feature|Hardwired Range Hood Plug-In Range Hood
Power Connection Wired directly into the wall by an electrician Plugs into a standard 120V outlet
Instalación Requires professional installation Easier DIY option if an outlet is nearby
Circuit Requirements More likely to need a dedicated circuit May share a circuit if amperage stays within limits
Appearance No visible cords for a cleaner look Power cord may be visible depending on placement
Common in… Built-in, high-performance, or luxury models Budget-friendly or retrofit models

If you’re installing a hardwired range hood, plan for a dedicated circuit, especially if your model includes advanced features or high fan speeds.
