Why Circuit Breakers Fail

Who doesn’t get a little frustrated when the power goes out every now and then? Especially when you’re in the middle of something. Circuit breakers seem to fail at the least opportune time. But why do circuit breakers fail anyway? First, let’s get back to the basics. We know that circuit breakers trip when there’s […]

How Circuit Breakers Work

Circuit breakers are safety devices that interrupt the flow of current. This happens if there’s either a gradual increase in load or a short circuit, which trips the breaker instantly. The most common times for a breaker to trip in a household are when devices which convert electrical energy to heat are in use. Examples […]

What Circuit Breakers are Compatible with Siemens?

Looking to replace circuit breakers in your Siemens electrical service panel? The straightforward answer is: read your panel for manufacturer’s instructions on acceptable breaker replacements. If the instructions are hard to read (normally they fade over time), then check your existing breakers and replace those with the same type. Firstly, remove one of the old […]

Ground Fault and Arc Fault 101

Ground fault and arc fault are sometimes used interchangeably but they are actually two separate things.   Ground fault is a type of short circuit sometimes known as “short to ground.” It happens when current going out on ungrounded phase (energized “hot” current) accidentally makes contact with a ground path. Electricity always wants to find a […]

Ground Fault Basics

Ground fault is simply a short in the system. It occurs when current going out on ungrounded phase comes back on grounded path. To avoid shock hazards, current going out any one phase must come back on another phase or neutral.   Ground Fault Protection A ground fault protection device is required to protect from […]
