Hi, I had an old range hood removed that was hardwired in. The new range hood is a plug in. Can the wires ( there are three wires) from the old range hood be used to wire a plug in outlet. The wall open so putting a box in will be easy.
If you are in the US, NEC 422.16(B)(4) requires that receptacle be a dedicated circuit for a range hood. If hardwired, the hood can be on a general lighting circuit. Reason for the distinction being microwave hoods are cord and plug connected, and might be installed in place of the vent hood at some point.
