Home Magazines: Often packed with quirky ideas of home improvement for the self-destructing HO. Some are better than others in self-censorship of just plain bad ideas, and others just let it all hang out. And in the past I have sent off a few letters to some about code violations and the like - but given the nature of thier material, one would think that they have some sort of editorial staff to vet out the weak or dangerous, or ill concieved. Or some that should be included with far more detail, so as not to confuse people who are inherently confused... But nonetheless, they keep coming.... Whats worse is that professionals are out there putting possibly neat or useful ideas out to the public in an ill-concieved, and haphazard way. This idea below is a prime example of a good idea that can go real badly in the hands of the wrong person. That said, there are not very many 'right' people for this little project.

What say you?

Wow, what a great arson tool!

Imagine a bunch of charging devices at the same time with the drawer closed.

Lots of heat [Linked Image] .

Would you say misuse of listed product as premis wiring and subject to physical damage? After all we dont know what "Flex Coil" is - DO WE?
I can see the drawer-mounted box being smashed by a wrongly measured drawer, and a couple of power strips in that drawer too.

The only way I can legaly (through 400.7) see an installation in this manner would be with 14 or 12/3 SOW, proper strain reliefs (90 degree on both), with metal boxes and non-concentric/eccentric KO use. And that would still call into play accessibilty of the box behind it depending on cabinet design. And the drawer would need to have some sort of limiting device. Even then I would opt for some sort of disconnecting method. And still I would have to get the AHJ to buy off on it. As it would look very much like a home-made extention cord I would doubt it.
Funny, I was thinking about SO when I saw that.

More likely what happens is someone sees that dishwasher receptacle under the kitchen counter, screws a plugstrip to the back of a drawer in the area and cubetaps it in with the DW. (perhaps a orange cord to make it reach). Hopefully they strain relieve the cable and secure it out of the tracks and up out of the cabinets.
Certainly SJT would be the minimum allowable cord but SO is more appropriate. I imagine you can find some "curly coil" SJT lookalike somewhere but it will probably be listed as fixture wire not building wire.

Looks like a great idea for someone to make, patent and get a UL for this use, then it would fine…right?
Posted By: Elviscat Re: Bad ideas from Architechs in home zines - 12/18/06 06:32 PM
if someone made a UL listed assembly, maybe included a big warning sticker on drawer "do not charge more than X appliances, make the drawer removable, put a molded recpt. in the back, have it plug into an EC installed receptile behind the drawer, and I think it could work

I agree that it's unlikely for someone to do this in a code compliant, <i> safe </i> manner as it's drawn

Just my dos centavos

it was rhetorical...

I wasn't answering your question I was just speculating on how this could be done legally... if you don't mind? [Linked Image]

I'm going to take something of a contrary view....

First of all, I don't think the NEC applies here. Once you come out of the wall, you have an "appliance," not part of the installation. NEC rules apply no more than they do on the inside of a kitchen range or dishwasher.

Next, I see a role for this sort of arrangement, especially with kitchen counters and computer stations. In both situations, you have equipment that you ordinarily want out of the way, but also want to be able to pull it out for servicing.

Indeed, I almost want to do something like this in my shop, so I can have my tool batteries being charged, secure, and not cluttering up the benchtop.

Necessity may be the mother of invention; convenience is an aunt. Unfortunately, their inbred cousin, the "Handy Hank" whose work appears far too often on this site, is never far away. If something is not readily achieved with off-the-shelf items, you can count on him to casually ignore sense, and mangle things until they sort of 'work.'

I would agree that the UL/NEC lines here are blurred... Nothing in the drawing suggests a 'product' or 'kit', but does suggest a mounted outlet box in a movable drawer, hardwired to an junction box via a non-chapter 3 method. (flex coil?) If "flex Coil" suggested NM to some as in a 'coil' of NM - it would be a violation, support physical damage... The outlet box in the drawer is not covered in 314.23(A) through (H). It might be considered with a wide view that it is 'pendant mount' but it isn't really, so it is quite possible a lack of support for the outlet box.

They do make, so I have found, a 'coiled' SOW, and SJOW, but as a circuit extension for a 15 - 20A circuit it would need to be 14 or 12. At which point that cord is going to be a BEAST behind a drawer. (.6-.75 OD with a coil diameter of 2 1/4")

And if it were a "Listed" product or kit, it would have installation details provided that would have specific parameters for the instalation of this... Probhably furnature equipment listing etc.

Bottom line, its a neat idea... But my AHJ would not sign off on it as drawn. With jumping around through a lot of code hoops I could make something like it work to code, but I am going to have 5 marker tabs in my book at the ready for the inspection, and even then it would be a crap shoot.

A case in point, remember those "Pop-up" recepticals someone posted in a recent thread? I know someone who tried to use them and got shot down as they were considered subject to physical damage behind a drawer - they had to have the cabinet maker build a dividing panel to protect the cord. (The electrician did not even install them - the GC did, and they were present at the final - EC got the hit...)
I really see this being cord and plug connected if Harry Homeowner is doing it.
I have something somewhat similar that is C&P. I built a sliding rack under the bathroom counter for my wife's hair dryer and other hair stuff. It has a HD plug strip in it with a 14ga cord and internal breaker, plugged into an undercounter GFCI receptacle. I did go to some care to strain relive the cord and make it fold in a gentle bend in a clear spot. I do have experience with cords and movable parts from the computer biz.

Most people would cobble this together, making it bad. But as mentioned, I think it could be done well:
  • Receptacle behind drawer
  • 12/3 SO with NEMA 5-15 plug and strain relief, going to strain relief at drawer
  • Permanant, boxed receptacle inside drawer
  • Cabinet bellow drawer to allow access
  • Drawer short enough not to crush cord
That way it's not hard-wired, it's accessable, it has a disconnect means, it's not subject to damage, it doesn't need additional OCP. Unless I'm missing something, I don't see the problem if carefully executed.

All that being said, it would be much easier, and much less questionable to simply put a receptacle in a cabinet and put the chargers in there.

I have a computer in a drawer here by my chair. I used a piece of 4" PVC vertical blind material attached to the drawer and to the back of the cabinet. That will form a smooth loop when the drawer is closed. I have all my cables attached to that strip. I didn't invent that. IBM did it on equipment where they had a bunch of cables going across a hinge or a moveable cover. It spreads the bending out evenly, secures the cables and keeps things organized out of other moving parts. You could do that here.

Our moderator is correct - Outside of the wall it lies outside of the scope of the NEC.

Huh? Are you saying ceiling fans, pendant lights or flex connected motors are not required to meet the appropriate NEC articles? None are "inside a wall".
The only way I see this being a grey area is if it is cord and plug connected.
I've done it. It was cord and plug connected and plugged into a GFCI receptacle, since it was in the bathroom cabinet. It's up to the homeowner to not burn their house down doing something I would call "stupid." [Linked Image]

It looked pretty sweet when I was done, despite the fancy custom drawer being almost exactly the same height as the receptacle coverplate was wide.

Surface mounted panels are ouside the wall... Surface mounted conduit too...

The line dividing here is the receptical... Otherwise it is Premises Wiring...
Quote
Premises Wiring (System). That interior and exterior wiring, including power, lighting, control, and signal circuit wiring together with all their associated hardware, fittings, and wiring devices, both permanently and temporarily installed, that extends from the service point or source of power, such as a battery, a solar photovoltaic system, or a generator, transformer, or converter windings, to the outlet(s). Such wiring does not include wiring internal to appliances, luminaires (fixtures), motors, controllers, motor control centers, and similar equipment.

And right up to the device in the drawer mounted box is a Branch Circuit. If there were a receptical at the wall, it would be utilization equipment....

I was referring to the picture not wiring in general.
