Article 406.8 Wet Locations
[1] States 15 & 20 Amp receptacles installed outdoors shall have in-use covers.

[2] Talks about all other receptacles. What other receptacles are they talking about if they have already said that all 15 & 20 amp receptacles shall have in use covers in [1] above?

They're talking about the 30A, 40A, 50A, etc....
Think about RV receptacles, Power tool receptacles (like a welder, I've seen it), generator receptacles, anything over 20A.

30 amp receptacles, for example, or 480V receptacles.

Not to argue, but a rhetorical question:

Are we to assume that more current carrying capacity or higher voltage equals less or no chance of shock or electrocution?
 
It's OK. Feel free to argue. ;)

I have no fact to offer. My guess is that nobody makes in-use covers for the other types. If they do exist, my next guess would be that their manufacturer's have not been successful (yet) in lobbying the code making panels.

Anybody remember seeing a proposal to add 30 amp receptacles to this requirement?

I agree with Charlie - It's harder to find in-use covers for larger plugs.

I also think its less likely that someone will leave their welder plugged in outside during a rainstorm, and less likely they will be welding in the rain.:)

Come to think of it, I can't think of any 30A equipment that would rated for use outdoors in a wet location.

How about one of these?

They are all over the country in campgrounds, RV parks, etc.
 
Not sure the brand but there is a in use cover that can be installed horiz. or vert. and comes with a slew of inserts that have to be ko`d for the application.They will fit everything from a duplex to a 50a receptacle.What I hated about them was that when installed depending on vert.or horiz. the opossing tabs had to be cut off to open or close them.tightly.

The same questions can be asked of 210.8 and 210.12.

I don't think it has anything to do with the availability of bubble covers.

IMO it has to do with accident statistics which show 15 and 20 amp 125 volt receptacles cause more injuries than other voltage and sizes.

Now did they take into account the large difference in the number of 15 and 20 amp 125 volt receptacles as compared to other sizes?

The NEC has already proved availability of an item to comply with code is not a consideration as evidenced by 210.12 and the 2008 change for weather proof receptacles.

We just installed a couple of them. They're the 14-in-1 kind, with a grey base and a clear cover. The hardest thing about using them is peeling out the two wire slots in the cover.

If I were to venture a WAG, I would say yes.

If 1% of any type of receptacle would kill someone without GFCI protection (i.e. 1% are damaged), and 90% of the receptacles people come into contact with are 15A and 20A 120V receptacles, then there could be a non-existant body-count with the other receptacles. 1% of 10% would be a fairly small number.

Perhaps they are playing the odds game, or perhaps we could see more GFCI protection in the future?

Perhaps it's more the use of the items we plug into them. People are far more likely to utilize a 20A 120V circuit and drop their weed-eater in the fountain. Who is going to plug into a 20A 480V and drop the appliance in water at some remote spot on an extension cord?

(Just thinking out loud...)
