406.9(B) Outlet Box Hood

[infinity]

Is this product considered an "outlet box hood"? IMO it is not and can be used even though it is not listed as "extra duty".

I use these all the time and inspectors never say a word. Customers like them because they don't stick out as far as a bubble.

I think this one is

Outdoor Comforts® 1-Gang Weatherproof In-Use Cover, Expandable, EXTRA DUTY®, Bronze | ML500Z | TayMac

but the one you show doesn’t pass 2017 language IMO

Nope. Look again. Model numbers are different
Mine has extra duty stamped on it.

Extra duty is required for a outlet box hood. IMO this product is not one of those so either of the ones posted could be used.

Couldn’t it be used in a damp location without being identified as extra duty

Code reference?

Hubbell presumably thinks that ML450Z is an outlet box hood. Why else would they create the ML500Z version and bother to list as extra duty?

disagree..
406.2 Outlet Box Hood. A housing shield intended to fit over a faceplate for flush-mounted wiring devices, or an integral component of an outlet box or of a faceplate for flush-mounted wiring devices. The hood does not serve to complete the electrical enclosure; it reduces the risk of water coming in contact with electrical components within the hood, such as attachment plugs, current taps, surge protective devices, direct plugin transformer units, or wiring devices.

And more directly, (2017) 406.2 provides the definition of Outlet Box Hood:

Outlet Box Hood. A housing shield intended to fit over a faceplate for flush-mounted wiring devices, or an integral component of an outlet box or of a faceplate for flush-mounted wiring devices. The hood does not serve to complete the electrical enclosure; it reduces the risk of water coming in contact with electrical components within the hood, such as attachment plugs, current taps, surge protective devices, direct plugin transformer units, or wiring devices.

The products pictured sound to me like they meet that definition.

So what would meet the definition of the bold? IMO this product meets that criteria.

406.9(B) Wet Locations.
(1) Receptacles of 15 and 20 Amperes in a Wet Location. Receptacles of 15 and 20 amperes, 125 and 250 volts installed
in a wet location shall have an enclosure that is weatherproof whether or not the attachment plug cap is inserted. An outlet box hood installed for this purpose shall be listed and shall be identified as “extra-duty.” Other listed products, enclosures, or assemblies providing weatherproof protection that do not utilize an outlet box hood need not be marked “extra duty.”

What makes one extra duty and the other standard duty. See nothing in description to indicate.

So what would meet the definition of the bold? IMO this product meets that criteria.

Something like an RV outlet box, where the cover goes over the whole box, not just the receptacle? The products pictured clearly are "housing shield(s) intended to fit over a faceplate for flush-mounted wiring devices."

First time that I have heard them called "outlet box hood". I just called them "in-use covers" and never saw the definition in the code. Guess I don't read enough in the 406 section.

That's the reason I posted this. To me the large bubble style covers would be a hood type. The accordion cover like in the OP would meet the other listed products exception that would not require extra duty. I was under the impression that it was because of those cheap bubble covers that broke so easily that the extra duty requirement was put into the NEC in the first place.

After some more digging it looks like they call this a hood cover at least according to the wording on the face;

Code reference?

406.9(A)?
