Yes the 16-gauge will work just fine. Make sure your connections are well insulated.

Can you use 18 gauge wire for 120v?

18 gauge wire is safe to use at low currents. It would be recommended to fuse it though. BUT, doorbell wire is not a safe option at 120 volts. Most likely it is not intended for use above 48 volts.

Can you connect 18 gauge wire to 12 gauge wire?

NO don’t ever mix AWG Wire gauges they are different for a reason and the main reason is amperage. Sure it will work but it’s 100% wrong and the #18 gauge wire becomes a fusable link and potential fire hazard. It would be easier to use the #18 wire to pull #12 wire and make it right.

Can you use 15 amp switch on a 20amp circuit?

You can, in fact, use a 15-amp switch on a 20-amp breaker lighting circuit since the 20-amp rating means that the circuit can handle anything up to 20 amps, so anything lower is alright to use.

What needs a 20 amp circuit?

Large consumers, especially kitchen appliances, such as microwaves, blenders and toasters, need a dedicated 20 amp circuit, to ensure a constant energy flow, which means they cannot share the circuit with other devices.

Can I plug anything into a 20 amp outlet?

You can use a device that has a 15-amp plug with either a 15- or 20-amp receptacle. Standard 15-amp receptacles are suitable for typical household appliances, lamps and other accessories. A 20-amp receptacle is for heavy-duty appliances and power tools, such as air compressors.

What is 24 AWG wire used for?

So, 24AWG cable is ideal for long runs with more potential damage, because it comes with stronger conductors with lower attenuation, while 28AWG slim cable would be more suitable to enable higher density layouts and make it easier for cable management since it helps save space and optimize airflow.

Is higher AWG better?

In general, a lower AWG number is better than higher AWG. AWG is of primary importance for wires that will carry electrical power — for example, home or business electrical wiring, extension cords or high-power wire in automotive or audio use.

What is 22 gauge wire used for?

Here at SparkFun, we typically use 22 AWG wire for prototyping and breadboarding. When using a breadboard or PCB, solid core is perfect because it fits nicely into the holes. For other prototyping/building involving soldering, the stranded core is #1, just be sure not to let too much current run through a single wire.

Does stranded wire carry more current?

Because of the given thickness of stranded wire, i.e., it’s thinner, there are more air gaps and a greater surface area in the individual strands of wire. Therefore, it carries less current than similar solid wires can.
