How many amps is #6 Romex good for?
So #6 NM typically has an ampacity of 55A. Since 55A is not a standard breaker size, it is permissible to protect it with a 60A breaker, provided that the calculated load is 55A or less.
What wire do I use for a 50 amp sub panel?
6 AWGFor 50 amps, you could use 4 AWG wire with 85A ampacity (a bit of overkill but it's OK), but you can never use 8 AWG wire with 50A ampacity (you will fry the circuit). In most cases, 6 AWG is an almost perfectly-sized wire for a 50 amp breaker. In limited cases, you will probably have to use a larger 4 AWG wire.

What is the maximum current a conductor can carry continuously under the conditions of use without exceeding its temperature rating?
Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in amperes or “amps.” You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating.
What is gauge wire?
What Are Wire Gauges? The gauge of a wire refers to its thickness. Each gauge is represented by a number, with smaller numbers representing thicker wire gauges and higher numbers signifying thinner wires.
What is AWG wire gauge?
American Wire Gauge (AWG) is a standard method of measuring and identifying cable thickness developed in the United States for electrically conductive wire. It is suitable for specifying gauges for round and solid conductive wires made from non-ferrous material.

For example, electrical circuits with higher amperage ratings require thicker wires to accommodate the load without experiencing excessive heat buildup. Using wires that are too thin for the specified circuit amperage can result in wire failure or ignition.
