If I want to run an appliance that needs 50 amps, is there any problem
with combining two 30-amp circuits of approximately the same length, as
long as the part that carries the full current is using properly-sized
cable? It seems like the circuit would have a 60 amp capacity.

Are the 30 amp circuits single ended or double ended? I have
seen them both ways. The 50 amp appliance is likely a double-ended
unit, which means it needs 220 volts rather than 110. If you
know that the two 30s are single ended and on opposite sides of
the AC mains, you might be able to make it work.

False and dangerous. What you propose would provide a 30A 220V circuit, *not*
a 60A circuit.

It would be far
better to put in the right wiring. You might be able to get by
putting in a 50AMP breaker, and using the 30 amp wiring, assuming
it is properly sized.

False and dangerous. If the wiring is "properly sized" for a 30A circuit, it's
dangerously undersized for 50A.
