Good possibility? It is a definite FACT. With the 30 amp
rating of the conditioner,a 20 amp plug would be a
requirement. Particularly on a 20 amp circuit.
Don't assume a 30A rating requires a 30A plug. That rating
is the maximum input current, and you can absolutely change
the plug to a lower rating if the load on the conditioner
is less than full load. The circuit protection is at the
panel feeding the receptacle, so if that receptacle is on a
15A or 20A circuit it is fine. If the load is too high the
breaker will trip.
That's such a screwed up fiasco from what I've seen/read, that it has to
have a 30A fuse and likewise be wired for "stopped rotor" & whatever
applies. We have no idea really what the situation is, wire gauge, voltage
during draw and resulting damage to inductive parts (motors, relays coils,
etc.).
What they need to do is get a real electrician in there to install things
correctly; they've made way too many bad choices. And then of course have it
inspected. It would not pass inspection right now.
