Electricity is an essential component of our daily lives, powering everything from the lights in your homes, to devices that we use each day.  However, electricity systems are complicated, and understanding how they work isn’t easy. In this guide we’ll breakdown the various components that make up an electric system and explain how circuits work to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

An electrical system has several essential components that work to supply power to homes. They include:

Breaker box is the central distribution point for electric energy in a house, where the electricity is divided into different circuits

Switches and outlets: places where electricity is delivered to appliances and devices

Wiring: the electrical wires that transmit electricity from the breaker box to outlets and switches

Electronic appliances and gadgets: the appliances and gadgets that rely on electricity for their functions.

Electrical Circuits

The term "electrical circuit" refers to a path that lets electricity flow from the main source (the breaker box) to the appliances and devices in the home. There are two types of electrical circuits that can be found in homes which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are employed for most household devices and appliances, whereas the 240-volt circuits are utilized for larger appliances such as dryers and air conditioners.

Electrical circuits function by creating an electrical loop that allows power to flow from the source to the appliance or device. The loop consists of a hot wire which transports the power along with a neutral wire that completes the circuit as well as a ground wire , which is the pathway for electricity to travel to the ground in the event of a fault.

Understanding the electrical Wiring

Electrical wiring is available in a variety of different kinds, including non-metallic sheathed cables (NM) as well as armored cables (AC) and conduit. Each type has its own advantages and drawbacks, and the choice of wiring type depends on the specific requirements for the particular installation.

The electricity travels through wires by creating a flow of electrons that travel through the wire. Electrons move between the origin and the device or appliance, and back to the source using the neutral wire. It is essential to ensure the wiring is installed and maintained correctly, as defective wiring could lead to electrical hazards such as shocks or fires.

Common Electrical Issues

Some common electrical problems that homeowners face include tripping the breakers, flickering lights, and dead outlets. The causes of these issues could be by a variety of factors such as overloading circuits loose connections, and faulty wiring.

If you experience one of these problems, it’s essential to identify the cause and take appropriate actions to rectify the issue. In some cases, this may involve contacting an authorized electrician to inspect and repair the wiring.
