When it comes to electricity every common man should know a few terms. It is not necessary to work with electricity but knowing something makes no harm. Electricians can fool their clients if the clients are not aware of what is going on. They can also fool by not completing the work when the commercial electrical installation is taking place.

Here are few terms which everyone should remember especially during the commercial electrical inspection and they are: –


  • Cable: the set of wires that surrounds the electrical component and acts as a protective outer layer is the cables. Cables are different from cords because cords are quite portable.


  • Circuit: through closed paths, electric currents are called circuits.


  • Circuit breakers: this is a device that any house owner can use to stop the flow of current in certain parts of the house. One can manually flip the switch to the ‘on’ or ‘off’ position just to manage the flow. This is an important function and also the first step for any kind of electrical replacement or repair work. If you are planning to do any work without the help of any qualified electrician then first turn off the power of the circuit breaker.


  • Conductor: any material through which electricity can flow is the conductor. Some of the conductors are metals like zinc, lead, nickel, iron, copper, aluminium, gold, and silver. Aluminium and copper are also conductors and they are present in the electrical wiring.


  • Current: just the way water flows through a pipe in the same manner current flows through a wire or conductor. The alternating current reverses its direction during intervals whereas direct current flows in one direction only. In homes, alternating currents are most used because they can be easily modified to increase or decrease the voltage. For this work you can call Electric Works London, they will come and fix the issue. Direct currents are also necessary for electronic devices because they need stable and consistent flow.


  • Fault: it is an abnormal electric current. For example, when a current pass there can be a fault it is called a short circuit. House owners install ground fault circuit interrupters just to protect any kind of imbalance in electricity.


  • Fuse: this device is made up of all kinds of wires that can break or melt the electrical circuit if the power exceeds, this is for the security of people and property. Fuses work as safety devices in our house. To replace or update the fuse always ask any professional electricians for help because only they will know all the regulations and do accordingly.


  • Generator: this device converts mechanical energy into electrical energy. Some people also use generators for portable electricity when tailgating or camping. Generators are important devices because they help to maintain power in the home when there is any kind of bad storm that might affect the current flow.


  • Voltage: this is a unit or metric that says how many electrical currents can pass through circuits. Some call its volts or only ‘V’. this measurement is the kind of water pressure that passes through a pipe.


  • Watts: it is a unit of electrical power that measures the amount of energy used every second by the current. One watt is equal to one Joule per second, this is the way to calculate.


Electrical terms for circuits: –

  • Alternating current or AC: this reverses its direction at every interval.


  • Direct Current or DC: it is also an electric current that flows only in one direction.
  • Feeder: all the circuit conductors in between service equipment, the source is separately divided. Or else the power supply source and final branch circuit overcurrent device.


  • Feeder pillar: it is also called the distribution pillar or power box. It is a kind of cabinet that is used to keep all the electrical equipment of the house. It acts as the central circuit that generally controls and also distributes electricity to all the circuits downstream that flows to the feeder pillar.


  • The ground of the Earth: this is the reference point in the electrical circuit and from this point, the voltage is measured. It is also the common return path for the electric current. It also has a direct connection to the earth.


  • Ground fault: it is an unintentional, electrically conductive connection that is in between the ungrounded conductor of the electrical circuit and all the normal non-current carrying conductors, metallic equipment, metallic raceways, metallic enclosures, or earth.


  • Grounded Conductor: this is a system that is intentionally grounded.


  • Grounded or grounding: it connects to the ground or to the conductive body that extends to the ground connection.


  • Knockout Set: it is also known specifically as an electrical knockout set or the knockout punch. This is one of the favourite tools that electricians use because it helps them to make new holes in the panel or the electrical box. The knockout punches also give various choices to them to make different sizes of knockouts. With the help of a socket wrench, the classical manual knockout pouches are made.


  • Load: anything that consumes energy like electric motors. Transformers, heaters, lights, and so on.


  • Neutral conductor: this is the neutral point of the system that carries current under normal conditions.


  • Overload: First of all, faults due to short circuits are not overload. Operation of any equipment due to excess of normal, full-load rating or a conductor in excess rate can cause damage by overheating everything. This is an overload that can be dangerous.


  • Parallel circuit: a circuit that has multiple paths for the electricity to flow in a circuit. Each load is connected in a separate path that receives the circuit voltage. The total circuit current is equal to the individual branch currents.


  • Rectifier: it is also a device that converts an alternating current into a direct one by allowing the current to flow only through one direction. There are 2 types of rectifiers: half-wave and full-wave.
