Are kitchen vent hoods normally direct-wired?

On my recent rewiring and new construction wiring jobs, I've been stubbing out an NM cable at 72" height for direct-wire to a vent hood. But I've noticed more and more appliances that used to be direct-wired now come with a cord and plug, for example dishwashers and disposers.
I am not familiar enough with vent hoods as they are sold nowadays. Do they normally come with cords and attachment plugs?

Most of the ones i've installed don't but some do. The tricky part is placement for the receptacle.
 
Thank you. My customer hasn't decided on a vent hood yet, and requested whatever is most common. On the other recent jobs I wasn't present during that part of the trim-out, but I guess it worked out OK on all of them to have it stubbed out at 6' above the floor.
 
I stubbed out NM for mine in the recent house build. The hood actually came in with a hardwired cord attached to it. I just mounted a box and recept up in the cabinet space around it and plugged it in. Or I guess you could put a cord cap on the NM and plug them together? I'm sure both methods are illegal per code since it's easy and somewhere someone will make life harder. I just wanted a disconnect means incase I had to pull it down and service or replace it. I don't know why things have to be more complicated than they need to be. :cool:
 
Every hood in this area is direct wired. If you use cord and plug then you would need a separate circuit
4) Range Hoods and Microwave Oven/Range Hood Combinations.



Range hoods and over-the-range microwave ovens with integral range hoods shall be permitted to be cord-and-plug-connected with a flexible cord identified as suitable for use on range hoods in the installation instructions of the appliance manufacturer, where all of the following conditions are met:
  • (1)
    The length of the cord is not less than 450 mm (18 in.) and not over 1.2 m (4 ft).
  • (2)
    Receptacles are located to protect against physical damage to the flexible cord.
  • (3)
    The receptacle is supplied by an individual branch circuit.
  • (4)
    The receptacle shall be accessible.
  • (5)
    The flexible cord shall have an equipment grounding conductor and be terminated with a grounding-type attachment plug.

Exception:
A listed appliance distinctly marked to identify it as protected by a system of double insulation shall not be required to be terminated with a grounding-type attachment plug.

I do a lot of custom kitchens, and the hoods that mount freely on the wall most generally have a cord with plug.

But the ones that get slit into a cabinet style hood are about 50-50 cord versus hard wire

I always just stub out a wire at about 7 ft right in the middle.

If it wall mounts and has a cord on it, I will nestle a shallow box next to the duct so it can be covered with the shroud
