If I want to run an appliance that needs 50 amps, is there any

with combining two 30-amp circuits of approximately the same length,

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.

Thanks in advance.

I suppose you could use two wires instead of one to increase your safe
amqerage on your wires but I'm pretty sure you would still need to use
only ONE 50 amp breaker in order to be good with wiring codes and
safety.
