2017 NEC 210.19(A)(3) Ex 1 with plug in gas cooktop

[Bjenks]

I found a 50A breaker going to a 30A 240V hardwired oven and a 5-15/20 receptacle outlet which I assume has 20A wire going to it. a 15A gas cooktop was plugged into that outlet. I am thinking you can't use the exception unless the appliances are hardwired? I assume a counter-mounted electric cooking unit includes a gas cooktop and not just an electric range?

2017 NEC 210.19(A)(3) Ex 1
Exception No. 1: Conductors tapped from a 50-ampere branch circuit supplying electric ranges, wall-mounted electric ovens, and countermounted electric cooking units shall have an ampacity of not less than 20 amperes and shall be sufficient for the load to be served. These tap conductors include any conductors that are a part of the leads supplied with the appliance that are smaller than the branch-circuit conductors. The taps shall not be longer than necessary for servicing the appliance.

I don't see that in the exception. But

I assume a counter-mounted electric cooking unit includes a gas cooktop and not just an electric range?

I would think a gas cooktop is not an "electric" cooking unit. FWIW, Section 100 has a definition of "cooking unit, counter mounted" that appears to be fuel agnostic.

I think was also throws me off is both Mike Holt and the Handbook have a graphic of a J-Box with FMC going directly to the appliances and thus leads me to believe they are talking about hardwired. Plus they seem to spend a lot of time talking about tap conductors and leads supplied with the appliance and not making those taps too long. Nothing about an appliance cord or a NEMA outlet.

A 15A or 20A receptacle on a 50A circuit would be a violation of 210.21(B)(3).
