Wiring a Range Hood Exhaust Fan
Electrical Question: I am installing a new range hood exhaust fan, how can I get power to it?
- I’m putting in a new range hood and I’m wondering how to access the house power.
- Would it work to add a junction box to the house conduit and run the Romex extension from there?
- That looks like three black together, three white together, and three grounds together. What do you think?
This electrical wiring question came from: Paula, a Handy woman from New York, NY.
Additional Comments: Thanks for the help.

Thanks for your electrical wiring question Paula.
How to Locate Electrical Power for a Range Hood Fan
Application: Wiring a Kitchen Exhaust Fan onto an Existing 120 volt Circuit.
Skill Level: Intermediate to Advanced – Best installed by a Licensed Contractor or Certified Electrician.
Tools Required: Depends on the exact scope of work. Electricians Tools including a Pouch Hand Tools and Voltage Tester.
Estimated Time: Depends on the personal level experience and ability to work with tools and access to the wiring.

Locating Power for a Range Hood Fan
- Paula, if the installed electrical wiring is in conduit then any added electrical wiring should be in conduit as well.
- This would be verified by calling your local building department.
- The existing conduit and wiring in question would require identifying each circuit to understand what these existing circuits serve and if they would have the additional capacity or even allow being branched off of. Some dedicated circuits should not be tapped into.
- A typical range hood exhaust fan may be fed from one of the 120 volt kitchen appliance circuits. There may also be a 120 volt outlet behind the range which can be used to supply the power as well.

Need to wire my stove hood back up after cleaning it black, white, and red wires coming from fan and light. black and white coming from main power source, and black and white coming from recp. where fan motor plugs in. I need to know how to tie them all in.
thanks

The power source wiring to a typical hood exhaust fan enter a junction box where there are black, white and ground or a ground screw terminal. So with that connection its color to color. From what you are describing you have taken apart the wiring that most likely involves the switch controls for the exhaust fan and the light, so you will need to identify the wiring to the switch for the light and the switch for the fan in order to make the correct connections for the fan and light. Your limited description of the unit and what you have taken apart does not provide enough information.
