If you are the owner of a business with an extensive infrastructure, you would be aware of the importance electricity plays in it. You require an uninterrupted supply to ensure maximum efficiency and optimal output. However, the kind of electricity used in businesses is different from those utilized in households or residential purposes. They are substantial in volume and often available in bulk rates, usually have a three-phase design and consist of tube-like conduits and ceiling rafters. In Sydney, the present electricity rate is 88.06 MWh AUD$. Therefore, having a commercial electrical contractor Sydney that you can count upon at all times is essential because even a slight delay in operations because of power failure can cost you a great deal of money. What are some things you must know about them, and how can you find the right one?

What is commercial electricity?

Difference in volts

As mentioned above, the electrical loads and requirements for commercial purposes vary from those utilized in residential areas or homes. Usually, commercial buildings have a three-phase wiring design using three legs. At the same time, the large leg operates at 208 volts, and the smaller one at 120 volts. This design ensures optimal efficiency, ensuring the machines last long.

Wires located outside

Unlike residential installations, where the pipes and wires are hidden behind the walls, ducting or conduits are used for wiring installations in commercial settings, as they are located outside. The cables used for the purpose also have more insulation to protect them from liquids and corrosive gases. Because they require frequent maintenance, they need to be accessible whenever needed.

Different energy requirements

According to Energy NSW (which provides all energy-related information on all the cities, including Sydney), all commercial and industrial areas must have 25kA for prospective short circuit current at the PCC for services till 400 amperes. They also state that since commercial loads require an enormous amount of reactive power, referred to as kVArs, to run furnaces, motors, electric discharge lighting and other equipment, it leads to a low power factor. Electricians can enhance the low power by using a capacitor to supply this reactive power, as your electrical contractor will tell you when you call them.

Do commercial electricians require a licence in Sydney?

According to the government of New South Wales (the capital of which is Sydney), all electricians, whether commercial or domestic, require an electrical license before installing, repairing, or doing any other kind of wiring work. Because electrical work involves a high degree of specialisation, various permits are available for the industry. For example, if someone applies for a contractor licence, they can contract and perform only those tasks that have been mentioned explicitly on their license cards. In Sydney, contractor licenses are issued to companies, partnerships and individuals.

Types of services provided by commercial electricians

A good, trustworthy and professional commercial electrical contractor in Sydney will usually provide the services mentioned below.

Detecting the electrical issues

Commercial electricians are trained to diagnose and repair any wiring or other issues related to your workplace. A trustworthy company will usually carry out an audit to ensure that the company’s energy operators are efficiently managed and detect any problems that act as an impediment. These issues include switchboard upgrades, new retail shop fit-outs, test and tagging, resolving issues with an outdated electric panel, and additional lighting.

Special lighting installation

A professional commercial electrician in Sydney will also provide services such as specialty lighting installation, including custom lighting options, after considering factors such as landscape, exterior, ambient, focal point, parking lot and workspace lighting. Simultaneously, they would check whether the power components and peripherals are in top working condition to ensure their safety and integrity.

Ensuring compliance with electrical codes and regulations

Commercial electrical contractors are familiar with the various power codes and regulations in businesses, offices and workplaces. They will take steps to ensure your company complies with them to avoid fines or penalties. If you have any unmarked, unapproved or non-compliant power tools, they will bring that to your notice or lodge a complaint if necessary. The state of New South Wales has specific rules which state that anybody who offers faulty electrical tools will face a maximum penalty of 825,000 AUD$ or 82,500 AUD$, or even two years imprisonment, in some cases.

Giving you a compliance certificate

In Sydney, as in all other cities of NSW, all electricians must provide you with a Certificate of Compliance for electrical work (CCEW) under the Gas and Electricity Consumer Safety Act 2017 and Gas and Electricity Consumer Safety Regulation 2018. They must submit the certificate within seven days of carrying out safety or compliance tests on an installation.

You must hire a commercial electrical contractor in Sydney who is trained, certified and adept at dealing with any electrical issues related to your business. Even the slightest power failure can affect your business significantly.
