Is a vent a hood allowed to tap into the 50 amp BC for the Range in a dwelling unit?
422.16(4) Range Hoods. 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 instruc-
tions of the appliance manufacturer, where all of the fol-
lowing conditions are met:
(1) The flexible cord is terminated with a grounding-type
attachment plug.
Exception: A listed range hood distinctly marked to iden-
tify it as protected by a system of double insulation, or its
equivalent, shall not be required to be terminated with a
grounding-type attachment plug.
(2) The length of the cord is not less than 450 mm (18 in.)
and not over 900 mm (36 in.).
(3) Receptacles are located to avoid physical damage to the
flexible cord.
(4) The receptacle is accessible.
(5) The receptacle is supplied by an individual branch
circuit.
For cord and plug, no.
So are you are putting its wires onto the range's branch circuit wiring, protected by a 50A breaker?

210.19A (3) Household Ranges and Cooking Appliances. Exception No. 1:
Conductors tapped from a 50-ampere branch circuit
supplying electric ranges, wall-mounted electric ovens, and counter-
mounted electric cooking units shall have an ampacity of not less than
20 amperes and shall be sufficient for the load to be served. These tap
conductors include any conductors that are a part of the leads supplied
with the appliance that are smaller than the branch-circuit conductors.
The taps shall not be longer than necessary for servicing the appliance
directly wired, yes>>

I'm not so sure.directly wired, yes>>
I'm not so sure.
Does this refer to the conductors being tapped or the conductors doing the tapping? I read it to mean the tap conductors feeding those appliances, not the tapped conductors.
This:
"Conductors (tapped from a 50-ampere branch circuit) supplying electric ranges, wall-mounted electric ovens, and counter-
mounted electric cooking units shall have an ampacity of not less than 20 amperes and shall be sufficient for the load to be served."
Not this:
"Conductors tapped from a 50-ampere branch circuit (supplying electric ranges, wall-mounted electric ovens, and counter-
mounted electric cooking units) shall have an ampacity of not less than 20 amperes and shall be sufficient for the load to be served."
:happyno:I ain’t sure by any means, RJ is stretching it IMO.
I think it still comes down to 422.16.4.5 that talks about hood supplied from single circuit, which seems to imply that it cannot be on a shared circuit or brought up from the cooker circuit... and again, wonder if this is for microwave hoods reasons or because of old units? Because most cooker hoods use less than 10 amps continuous use...including the lights.
A range hood is not, imo, what is being talked about in 210.19. A hood is not a cooking appliance. That section is meant for a circuit that feeds say an electric cooktop and a wall oven. The taps are the wires from the appliances. JMO
Interesting. Never heard of using that code section for a vent hood.
Not convinced it applies but willing to think about it.
Hmmmm.....
