What is a characteristic of the level below 22 AWG?

A characteristic of wire gauge is that as the gauge number decreases, the wire becomes thicker. Consequently, a wire below 22 AWG is thicker than 22 AWG wire, which allows it to carry more current. Thicker wire gauges have a lower resistance and this generally results in lower impedance, supporting higher current capacity.

In the case of wires with a gauge number greater than 22, such as 24 AWG or 26 AWG, they do indeed have lower current carrying capacities compared to thicker wires like 22 AWG and below. This is due to their thinner structure, which creates more resistance and a higher risk of overheating when carrying current. Thus, wires that are below 22 AWG will have lower current capacities than their thicker counterparts.

Recognizing these characteristics is crucial when determining wire suitability for specific applications in alarm systems or other electrical setups, as it directly impacts performance and safety.
