Electricity is an integral part of our daily life, powering everything from the lighting in our houses to appliances we use every day.  However, electrical systems can be complex, knowing how they work can be challenging. In this guide, we’ll break down the components of an electrical system, and describe how circuits function to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

A home’s electrical system includes a number of key components that work together to supply power to a home. They include:

Breaker box: the main distribution point for electric power in homes in which the power is split into various circuits

Switches and outlets: points at which electricity is supplied to appliances and devices

Wiring: the wires that transport electricity from the breaker box, to the outlets and switches

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

Electrical Circuits

A circuit of electricity is one that lets electricity flow from the point of origin (the breakers box) to the appliances and devices in a home. There are two kinds of electrical circuits that can be found in homes which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are utilized to power most household appliances and appliances, while 240-volt circuits are used for larger appliances such as dryers, air conditioners and electric ones.

Electrical circuits work by creating the loop which allows electricity to flow from the source to the device or appliance. The loop is made up of a hot cable that is the conduit for electricity and a neutral wire which completes the circuit and a ground wire , which is an avenue for electricity to reach the ground in case of a fault.

Understanding Electrical Wiring

Electrical wiring is available in many kinds, such as non-metallic sheathed cables (NM), armored cable (AC), and conduit. Each kind comes with its own pros and drawbacks, and the choice of the wiring type is contingent upon the specific needs for the particular installation.

The electricity travels through wires by creating a flow of electrons in the wire. Electrons move from the source to the appliance or device, and back to the source using the neutral wire. It is essential to ensure the wiring is put in place and maintained correctly, as faulty wiring can lead to electrical hazards such as shocks or fires.

Common Electrical Problems

Common electrical issues in homes include tripping light bulbs, flickering breakers and dead outlets. These problems can be caused due to a variety of reasons, including overloading circuits, poor connections, or faulty wiring.

If you’re experiencing any of these issues it’s essential to identify the source and take steps to correct the issue. In certain instances, this may involve contacting an authorized electrician to inspect and repair the wiring.
