Most local codes require that when extending or adding circuits, the circuit must be brought up to national code standards. This would necessitate that if you have a 2 wire circuit and are adding to it, that you rewire the entire circuit to 3 wires.
However, in actual practice, it is common to see 3 wire nmb connected to 2 wire nmb without full re-wiring. It is important to note that when this happens, the ground wire in the 3 wire cable serves no purpose. You end up with what looks like a 3 wire grounding configuration at a receptacle or other outlet when in actuality you have no equipment ground. This allows a hazard to exist that no longer conforms to current code, and if someone were to be injured you may be held liable.
Yes, you can connect a 14 gauge NMB 2-wire cable to a 14 gauge NMB 3-wire cable using wire connectors like wire nuts or push-in connectors. Make sure to match the wires by color (hot to hot, neutral to neutral, and ground to ground) and ensure a secure connection to maintain safety and compliance with electrical codes.
It is not recommended to connect a 14 gauge wire to a 12 gauge wire on a 20 amp breaker, as this can create a safety hazard. It's important to match the wire gauge to the circuit breaker rating to prevent overheating and potential fire hazards. It would be best to run a continuous 12 gauge wire for this circuit.
To determine the gauge of wire in your house, look for markings on the insulation or jacket of the wire. It usually indicates the gauge size, such as 14, 12, or 10. You can also use a wire gauge measuring tool to accurately determine the wire gauge.
The lower gauge number is always a thicker wire which can carry more current.
The AWG wire gauge with the highest number indicates the smallest wire diameter. For example, AWG 40 wire is much thinner than AWG 10 wire.
When looking to purchase a 14 gauge speaker wire it may be possible to buy the required length and brand of wire from a local Hi-Fi shop. There are online websites that offer 14 gauge speaker wire and these are sites such as Amazon and Walmart as well as many other sites that offer speaker wire.
16 Ga wire is smaller than 14 Ga. The answer is absolutely NO!

it is not recommended because the 14 gauge wire is not capable of carrying the same amount of load as the 12 gauge wire which could result in a fire.
no
The gauge of wire that is 12 volt is 18, 14, and 16.
The lower gauge number is always a thicker wire which can carry more current.
They are close but not the same. For example, 14 gauge steel is .0781 inches thick while 14 gauge steel wire is .083 inches thick.
No - the two have no relationship to each other at all.
0.064084 diameter
The AWG wire gauge with the highest number indicates the smallest wire diameter. For example, AWG 40 wire is much thinner than AWG 10 wire.

It is better to use 16 gauge or 14 gauge speaker wire for your home theater applications.
