Multiple 240V appliances

I have two cooking appliances that are rated 12A @ 240V in a non-dwelling and not a kitchen (no sink in this room).

Can I put these on a single 30A 2P circuit?

My confusion is that they each use a 15A 240V cord and plug connection. Each is 12A, circuit rating needs to be 12A X 125% = 15A. However, 210.21(B)(3) reads:

(3) Receptacle Ratings. Where connected to a branch circuit supplying two or more receptacles or outlets, receptacle ratings shall conform to the values listed in Table 210.21(B)(3), or where larger than 50 amperes, the receptacle rating shall not be less than the branch-circuit rating.



Tables 210.21(B)(3) and 210.24 identify that receptacles on 30A branch circuits must be rated at 30A. My receptacles will be 15A/240V to match the appliance cords.

Does this mean I have to run two 15A 2P circuits?

What are the chances of them being used at the same time? If it's unlikely, you could put them both on a 20 A circuit. Or you could run a 30 A circuit and put a fused switch at each location to protect each one at 15 A. Or you could run a circuit to each one. Which one is the easiest and cheapest and best way to get the job done?

Both will be used at the same time. I will check the size of the existing conduit to see if I can run separate circuits after derating.
