Awg #6
AWG # 10 wire on 30 amp circuit.
Number 2 American Wire Gauge
40 amp
No. The 20 amp breaker is probably protecting a #12 wire. Connecting a 40 amp breaker to the 20 amp #12 wire would seriously overload the #12 wire. This means that if the load increased to a full 40 amps the insulation on the smaller size wire would most likely melt off and the wire could short out.

AWG # 10 wire on 30 amp circuit.
A 12 gauge wire can support a load of approximately 2200 watts.
Number 2 American Wire Gauge
The correct size fuse needed is based on the size wire used in the circuit. The size wire needed is based on the load that will be applied to the circuit. 1. AWG 14/2 wire = 15 amp fuse 2. AWG 12/2 wire = 20 amp fuse 3. AWG 10/2 wire = 30 amp fuse 4. AWG 8/2 wire = 40 amp fuse
40 amp
No. The 20 amp breaker is probably protecting a #12 wire. Connecting a 40 amp breaker to the 20 amp #12 wire would seriously overload the #12 wire. This means that if the load increased to a full 40 amps the insulation on the smaller size wire would most likely melt off and the wire could short out.
Yes, as long as the load attached to the wire does not exceed 0.022 amps.
