gascircuit breakers tools for middle voltages

The circuit breaker protects the wire, so in almost all situations, the breaker and all the conducting wires in the circuit that it protects must match. So if a 20A breaker is installed, all wires in that circuit must be at least 12 gauge. Your question about the compressor depends on what the manufacturer requires.
