Is there a difference(blade configuration-wise) between a 50A and a 40A range cord/cap assembly?

We recieved a shipment of ranges that were "supposed" to have a 50A cord attached. Some of these appliances have a 40A cord/cap attached. At a quick glance, the 40 and 50 configuration seems to be the same? The wire size IS different.

These cord/caps are of the 4-wire variety. I did not see a 250V 40A 4-wire cap here:

See table 210.24 2002 NEC.

Would T210.24 even apply....
The requirements for circuits that have two or more outlets or receptacles, other than the receptacle circuits of 210.11(C)(1) and (2), are summarized in Table 210.24.

Maybe 210.23(2)(C)?

However, the CB is a 50A 2P.
 
It is not uncommon to use a 50 amp receptacle with a 40 amp conductors and a 40 amp OCPD. This is permitted by 210.21(B)(1).

He said it was on a 50 amp 2P. I don't think that meets the 40 amp OCPD.

Are all the ranges one make and model? Or are they differing in kW?
 
Also, if you turn to Article 406 in the NEC Handbook you'll find Exhibits 406.3 and 406.4 showing the ANSI C73 Standard Configuration Charts. There is no "40 A" column.

The manufacturer will size the cord to the load of the range elements.

Kinda like the small gage conductors in a luminaire.

The cord is not part of the Premises Wiring (System).

I don't believe that's what he said. He said it was supposed to be 50 amps but the cord conductors are only rated for 40 amps. It would be permissible to use this cord with a 40 amp OCPD and a 50 amp receptacle.

Upon further review of this shitment, I find:
30A 4W cords
40A 4W cords
50A 3W cords
50A 4W cords

So now we muct "inspect" them ALL....and find:
Loose connections
No connectors
N-G Bonding still in place
G to "any ol' screw"

etc

To clarify the original post:
All ranges have a 50A 2p OCP
All cords were to be 50A 4W
All ranges are the same make, various models (skin color ~ White, Stainless, etc)
 
The cords are fine if they are properly sized for the equipment. The OCPD will have to match the conductor size of the cord. The receptacle can be equal in size to the cord or larger.

That's a pretty impressive and fanciful set of inconsistencies. Sorry they blew the order.

Are the kWs of the ranges all the same?

Larry, the OP doesn't mention the OCPD.
"Excuse me, sir. Seeing as how the V.P. is such a V.I.P., shouldn't we keep the P.C. on the Q.T.? 'Cause if it leaks to the V.C. he could end up M.I.A., and then we'd all be put out in K.P." ~ Robin Williams as Adrian Cronaur in Good Morning Viet Nam
