Electrical Installation basics

Understanding The Electrical Installation Basics and Components In Your Home

Understanding the basic electric parts and components in your home is very important. Let’s take a look at what the meter box, circuits, fuse board and breakers do and how they work.

The Meter Box

When electricity is delivered to your home, it first goes through your electric meter box. This is what measures how many units of energy your household uses.

This is measured in kWh – kilowatt hours – and is what your energy provider uses to determine how much power you used during your billing cycle (and hence how much you will be charged).

You are charged by the number of total units used in a cycle, meaning the total kWh used. 1 kWh is the amount of watts used, multiplied by the number of hours used, divided by 1000.

For example, if you use a 1000W appliance for one hour every day, then the total kWh used by this appliance is one kWh per day. How much this costs you will depend on your energy provider.


For energy to flow to light sockets and power points in your home, it needs to travel through a path or “circuit”.

It is called a circuit because it contains two wires: one that delivers electricity from the generator to the destination (this is ‘active’) and one that carries electricity back to the generator (this is ‘neutral’), thus completing the “circuit”.

The Fuse Board

The circuits delivering electricity to different parts of a house are all connected to single fuse board. This is the “brain” of the whole system.

When electricity is delivered to a house, it first flows through the meter box, then is carried to the fuse board.

From there it is distributed throughout the house via various circuits, hence why is it also called the ‘distribution box’.

There are not circuits for every powerpoint and lighting socket in a house, rather they are grouped into different categories (for example there may be one for your hot water system, one for your stove, three for your power points, and two for your lighting).

Circuit Breakers

Each circuit group has a switch, which are called ‘circuit breakers’. Labels will usually indicate which part of the house each switch controls.

In the event that a circuit is overloaded it could become very hot and pose the risk of starting a fire. The circuit breaker’s job is to stop this happening.

If the current flow exceeds the rated amp value of the circuit, the switch is opens, “breaking” the flow of the current, shutting the power off to that circuit in a extremely short amount of time, stopping any chance of an accident happening. The circuit can be connected again simply by closing the switch.

Main Breaker

The fuse board also has a “main breaker”. This is the first component that receives electricity after the meter box. This is kind of like the master power switch – if you need to shut off power for the entire house, simply flip this switch.

Trip Switch

The trip switch is a kind of master circuit breaker that monitors the flow of current through all wiring and disconnects the supply of electricity if it detects any abnormalities, from the tiniest imbalance (such as if a power board is overloaded) to large surges (such as during a storm).

If the amount of current flowing in is the same as the amount flowing out, the switches remain on. If there is an imbalance, the switch is “tripped” and the flow of current to the entire house is cut off.

4 Tips to Help You Hire a Good Electrician

It’s important to feel comfortable about the electrical service you plan on hiring and there are a few measures you can take to be confident that your house is receiving the right treatment.

Do Your Research

There are a few things you can research so that you can make sure that you are prepared to find the right person for the right job. You don’t have to be an expert, however, learning a little about the job and cost of the parts will help you to better deal with the electrical service.

It’s also a good idea to do a bit of a background check on any service provider you plan on calling. There may be references and reviews online that could give you a bit of an idea of the job you can expect.

Obtain a Quote

Before any work begins, it is a must that you receive a quote and agree on a price. It’s not abnormal to receive numerous quotes from different companies to compare prices.

Any business or contractor that pressures you to take the quote, start work early or don’t agree to you obtaining other quotes should not be trusted, as they do not have your best interests in mind.

Some electrical providers may even offer discounts to new customers in order to engage them long-term business, so be sure to shop around.

Insurance and Licensing

It is crucial that the provider that you hire has the appropriate insurance and licensing to carry out the work that needs doing.

This type of work is risky business and complications can mean damage to persons, as well as your own property, with extensive financial and legal ramifications.

Contractors should willingly provide you with the required details and if the service provider is part of a larger company it should be easy to check by calling the business and give yourself peace of mind.

Time Management

Time management is the sign of a skilled practitioner and is essential for electricians to complete their work in a given time frame. An electrician should provide a detailed timeline, along with an estimation of the cost of the job.

Like most things in life, the process may require a bit of adjustment, however, as you will be the employer, you need to factor in the timeframe and labour costs so that the project progresses to and continues to fit within your budget.

A good electrician should be able to keep you updated on the progress of the project every step of the way and stick to set goals and milestones, so make sure they have a good plan upfront.
