Installing Wiring for a Range Hood Exhaust Fan: Wiring a Range Exhaust Fan From an Existing Power Source or Outlet

Wiring a Hood Exhaust Fan

Electrical Question: One of my apartments needs a fan that goes over the stove, it’s a simply fan with light.

  • Can I run a electrical wire from a nearby outlet through and in between the wall and to the fan, or do I have to run the electrical wire from the circuit breaker in the basement all the way up to the third floor apartment on the left.
  • I am just trying to do it right by the housing code and safe.

Can you please help. Thank you.

This home electrical question came from: Rosa, in Newbedford, Massachusetts.

Additional Comments: Its great and very helpful.

Installing Wiring for a Range Lighted Hood Exhaust Fan

A lighted exhaust fan over the cooking stove or free standing range is a great way to add light to the cooking area and help control the spread of cooking odors and grease through the home, and this would be a great weekend project.


Skill Level: Beginner to Intermediate.
Tools Required: Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with tools,  access to the power source for the new hood fan. This would be a great weekend project.
Precaution: Identify the existing power source circuit, turn it OFF and  Tag it with a Note before working with the wiring.
Notice: Installing electrical wiring for additional outlets should be done according to local and national electrical codes with a permit and be inspected.

  • Wiring a Range Exhaust Fan From an Existing Power Source or Outlet
    •  Most conventional hood exhaust fans require 120 volts electrical power and they do not draw a lot of amperage therefore an exhaust fan with a light does not require it’s own circuit, so yes, a wire may be attached to one of the existing wall outlets.
    • Be sure to match the new electrical wiring to the existing wiring of the source you choose as the power source.
    • Typically a good power source would be a 120 volt receptacle outlet behind the range or a nearby counter top outlet.
    • The new cable for the exhaust fan may be directly routed into the junction box location of the fan unit or brought into a junction box inside the upper cabinet above the range or cook top stove where the hood fan will be installed.

    Can I hook a under the cabinet hood fan to a outlet in the same area with out going int a attic?
    Thank you.

      Hi Tom,
      That would depend on how far away the outlet is. If the outlet is close by and in the same stud bay of the interior all framing then a wire can be fished up to the location of the hood fan. However, before you do this, you should check to see if you have a 120 volt receptacle outlet behind the range or stove, and if so just fish a wire up from that outlet to the hood exhaust fan. This is the typical method we use to provide power for the exhaust fan.
      I hope this helps,
