A construction site has special electrical requirements. Not every electrical firm will provide such services since there are special standards to uphold and legal requirements to fulfil. 

A strong electrical system is essential to power the advanced and heavy-duty tools and machinery needed during construction. The electrician needs to ensure the safety of all the people involved even if it is a temporary setup. 

The power requirements for a construction site vary and they are not likely to have the conventional setup either. This article provides essential tips and information on electrical installations on construction sites.

 What are the Electrical Works in Construction?

High power is necessary for all the electrical equipment used on a construction site, like heavy-duty machinery and the complex network of electrical installations. This can either be interlinked or standalone. Here is a list of common electrical services needed at a construction site:

Temporary power supply

A construction site has high power requirements and it is wrong to assume that you will access power instantly and setting it up will be easy. It might be that it is located in a rural location or there are several geographical challenges. 

The local electrical company may help set up power temporarily; but you will need the expertise of a trained electrician to power up your construction site.

Fixed wiring

Fixed wiring is essential for all the electrical activities necessary on the site. This includes ensuring all the vital spots of a construction site have electrical power to use the heavy-duty equipment. This means installing power cables, sockets, distribution boards, etc.

Electrical switchboards

A switchboard is an essential hub that is necessary to direct the electricity stream for the needs at the site. This will act as a source of power for the entire site with well-defined sections like the main power unit and that necessary for the distribution.

Circuit breakers

A construction site also requires basic safety measures to be implemented. An electric shock is one of the most common threats; this can be avoided by installing a circuit breaker in place. This type of system is designed to minimize the risk and protect those working with electrical devices.

Overhead solutions

Installing an overhead distribution is one of the most cost-effective solutions and is also preferred by professionals to provide temporary power to the working site.


Generators are a common sight in this type of zone. Its portable nature ensures you can power your electrical devices in the remotest places. However, setting it up is something that should be best left to the professionals.

Underground solutions

It is highly likely that there will be a requirement for power underground as well. You can trust industrial electricians to meet your power requirement by connecting a power source underground.

High voltage solutions

They have innovative methods of meeting your high demand for power and do so by ensuring you have the least downtime. They will be able to supply you with high voltage power irrespective of the distance and power requirements.

What is Construction Wiring?

Constructing wiring should be of the high Australian standard irrespective of its meaning, like construction, demolition, switchboards, sheds, lighting, etc. There are many types of construction wiring. This includes that from the main distributor of the existing switchboard to the rest of the prices. 

It is essential that the wiring is not entwined along with the permanent wiring and cleanly visible using a unique colour tape. The other types of wiring requirements at a construction site include:

Overhead wiring

The right way to install it is to ensure it does not cross vital roads or access paths; especially those used by heavy machinery. In the case where it is essential for the wire to cross the road, it is a good idea to raise it high enough for the large vehicles to pass without any issue.

Permanent wiring

It is vital to isolate the permanent wiring in the case of demolition work since it can be live. On the other hand, take necessary steps to ensure it is not active prior to approaching the space. It is also necessary to avoid damaging the permanent wiring during the construction work by isolating it properly and protecting it from common threats.

Temporary wiring

Installation of the temporary wiring is done from the main source to the rest of the construction site where it is necessary. Utmost care needs to be taken while extending the cables to all the places. A construction site is already full of dangers at every corner; this electrical wiring should not add to it.

 Tips to find industrial electrician

What to expect from professional electricians

It is quite understandable to wonder “Why is electrical installation important in construction?” Professional industrial electricians ensure safe electric installation by providing a wide range of services to several industries. 

This includes emerging responses, design and construction, preventive maintenance, urgent repairs, thermal imaging, emergency lighting, communication cabling, energy management, and more. 

The requirements of a construction site are likely to be unique, however; you can trust an industrial electrical engineer to help you with it.
