and it sounds like OP might have a 10-50 recep and a 6-15 plug, don't
really want to be plugging a 15 amp or less device into a 50A circuit,
unless the device itself has a main fuse or breaker. Important concept
is recep amp rating must match the breaker, except in the instance of a
15A 120VAC recep being allowed on a 20A branch circuit.

I'm not following why it's a problem to plug a 15 amp device into a 50
amp circuit, assuming they are both, say 220volts. How is it any
different then plugging a cell phone charger into a 15amp 120v
circuit?

I don't see that as a problem either. Maybe in some devices that do not
have any internal protection it could. The devices plugged in should have
their own fuses/breakers for their own protection. The main breaker is to
protect the wiring.
