Can you imagine life without electricity? When the power is out, chances are you will feel anxious and on the edge. That’s why it’s important for homeowners to know and understand some of the most fundamental technical terms related to the electrical system.

Although electricity is consumed on a daily basis, most homeowners are not educated on basic electrical terms. What’s worse is that they have little to no idea on the dangers of electrical malfunction and the strategies to minimize accidents when handling electricity.

To enrich your electrical vocabulary, take a look at some of these terminologies that professional electricians use regularly.


This term refers to a path or route wherein electricity can pass. Technically it’s called “electrical circuit”, but professionals who handle this type of job are accustomed to use the term “circuit”.

As the term implies, it’s constructed as a circular or looping mechanism. Electricity is carried out by electrons that pass through the circuit. The electrons will do one of two things: (1) leave the circuit towards a ground or appliance, or (2) return to the power source to complete the circuit.

Short circuit

This phenomenon occurs when an ungrounded circuit accidentally connects with a grounded circuit. This is usually caused by an abnormal connection (whether intentional or accidental) in varying voltages. When this happens, parts of the circuit with low resistance may experience overheating, thereby causing fires or circuit damage.

Some of the common culprits of short circuit include faulty wire insulation, house pests, loose wire connections, and malfunctioning appliances. If you suspect any of these issues in your home, take the initiative to call us at Wire Craft Electric so that we can help you protect your home from further electrical damage.

Circuit breaker

This is a device that automatically breaks or stops the flow of electrical current. It’s usually designed as a safety tool to prevent electrical circuit damage, mostly from a power overload or a short circuit.

You may find this either inside an electrical box or installed on its own in a conspicuous area of your home. Don’t be afraid to touch this device, because this can really save you from electrical accidents.


This term refers to a reference point of any electrical circuit, either as a connection to the earth or a return path for current. A ground may be accidental or intentional, the latter of which is extremely important in preventing damage of home electrical devices from power surges. In other words, grounding will help your electrical system offload any excess current.

Final Word

Basic knowledge of electrical terminologies is a must for homeowners in order to help identify areas where electrical system problems may arise. Knowing these things is also important when it comes to describing your electrical problem to the technicians for further troubleshooting and repair.
