actually sounds like could either be a NEMA 6-15 15A 250V rated plug or the
30A 250V rated plug NEMA 6-30
The only difference is the 15A has smaller blades and the 30A blades are
larger

the plug is 3 prong and shaped as follows two lower blaces ot 180
degrees and center is a round prong. sort of like this but with the 2
180 degree blades lower than the center round prong _0_ can I
assume the 2 blades are to 120 v + and - legs while the center prong
goes to ground.

applience requires 30 amps of breaker so I will be using 2 15 amp
breakers and a 10 foot run of 10 gage copper.

That sounds like a 15A receptacle. You'll burn it up with that 30A
electric heater. You need two 30A breakers (tied together at the
factory into a single unit), and a 30A plug and receptacle. I would
probably use a 3-wire dryer receptacle, or a 50A welder receptacle even
though they technically not the right ones, because they are adequate
and are easy to find.
