What does that mean? If it has no whip or cord you can chose to install either.
The ranges I have seen have a 3/4" ko and 3 terminals inside the range. IMO, this is designed for a cord however I can imagine one could fight a piece of 8 nm with a lug or stakon. Why would you do that especially since there is no way to fasten the wiring. NM cable doesn't have the flexibility of a range cord. The terminals are very close to the ko so I guess if you want to run it in there and fight it then by all means. I just don't think it was designed for that.
Cords on what? Cooktops, ovens ranges?
I have never seen any of those items have a factory installed cord alaways an option.
I have never seen a residential oven without a whip. Even the double ovens have a whip. Slid in ranges have whips but free standing ranges have the KO which , again, IMO is set up for a range cord. Does the instructions say uses a cord--- IDK,,,

**If connecting to a 50-amp circuit, use a 50-amp rated cord withkit. For 50-amp rated cord kits, use kits that specify use with anominal 1³⁄₈" (34.9 mm) diameter connection opening.
