  • How to Identify Circuit Breaker Types

    Standard Circuit Breakers; When you imagine a simple breaker that trips when a circuit overloads, you’re probably thinking of a standard circuit breaker. Depending on the function (whether your protecting overhead lights vs. a washing machine, or a residential vs. a commercial circuit) you will need either a single-pole or double-pole breaker

  • A Guide to Wire Gauge Sizes - Precision Manufacturing

    American Wire Gauge standards range from 0000 (which can handle up to 302 amps) to 40 (which can handle up to 0.0137 amps). Most household and commercial wiring demands range from 2 (95 amp maximum) or 3 (85 amp maximum) to 14 (15 amp maximum). In the table below, we outline all of the AWG cable sizes and their unique properties.
