Best Free Open Source Electrical Design Software (2023)

When it comes to building infrastructure, whether commercial or residential, it entails planning, designing, creating, testing, and supervising the lighting equipment, and power systems within the premises. The installation of lighting fixtures and power systems may include electronic components, fire and life safety systems, voice and data communication systems, or anything that has to deal with electrical wiring connections. Electrical drafters prepare electrical wiring and layouts, which are then used by the workers who install, maintain, and repair electrical wiring and equipment in power plants, manufacturing units, communication centers, or any type of building. Basically, electrical design is the workflow or plan of connecting all the electrical components.

Electrical design plans can be as simple as connecting a few light bulbs and as complex as building the power system for a huge manufacturing unit. The main purpose of preparing electrical design plans is to ensure that the entire power system in infrastructure is safe and efficient enough to keep the energy costs low. If you are facing flickering lights, high electricity bills, and damaged equipment or machines in your premises, then that means you are using unstable systems or manual methods to design your electrical system.

Below are some issues that electrical engineers usually face while preparing an electrical system design -

Here we have listed the 7 best free and open source electrical design software that you can consider deploying for your business. But, before we proceed with the details of these electrical design tools, let's have a look at what exactly is an electrical design software, benefits of using it, and the features to look for while selecting one.

What Is Electrical Design Software?

The electrical design software, also known as the electrical CAD tool, helps in preparing the plans for electrical projects and reorganizing the current ones. The electrical software includes the library of symbols and the database of electrical parts and supplies, enabling electrical engineers and designers to model, document, and estimate the specifications and cost of an electrical design project. Moreover, the electrical design systems also allow you to share the electrical design plans digitally with the entire team, stakeholders, and Government authorities for required approvals.

Must-Have Features of an Electrical Design Software

Drawing Tools

(Video) 7 Best Free And Open Source Electrical Design Software

This is the most basic feature that is available in almost all the electrical design solutions. You need to check whether the design tools available in your electrical design solution are intuitive enough, allowing you to prepare your electrical designs quickly and seamlessly or not. It should also enable you to compare two versions of a drawing, easily helping you to create flawless and simple to understand electrical designs.

2D/3D Designing

The 2D/3D designing features allow you to design professionally presentable electrical designs. Some electrical design tools allow 2D drafting, drawing, and annotations for your electrical designs. In contrast, some tools allow 3D modeling and visualization, and some may even provide a combination of both of them. Depending on your business requirements, you can choose electrical design software and add flexibility and intelligence to your electrical plans.


The electrical design solution you select should allow you to customize your interface as per your business logic so that you can save the time consumed for performing repetitive tasks and improve accessibility. Also, it should enable you to set your compliance rules depending on your local government and industry standards, ensuring that your electrical designs fulfill all the rules and regulations that are required to gain quick approvals from the authorities

Data Management

Your electrical design software should allow you to import/export data from other applications, re-use that information, make changes to the existing electrical designs, and share those designs with team members for suggestions and higher authorities for the approvals. For example, inserting a geographical location in your electrical design or attaching models with your drawings should be an easy task.

Multiple Platforms and Devices Support

The electrical CAD software you select should allow you to create, edit, and share your electrical drawings from any device or platform. Moreover, you should be able to publish your electrical project presentation in multiple formats allowing users to access it easily and provide their comments and suggestions.

List of Electrical Parts & Supplies

After the design is ready, you don’t need to manually prepare the list of electrical parts and supplies required to complete your project. The electrical design software generates the list of electrical parts & supplies automatically. This would ensure that you place the order for the right quantity of electrical parts & supplies required for your project, eliminate the chances of wastage, and save your money.

Integration to Purchasing Channels

Many electrical design solutions integrate the purchasing channels for buying electrical parts required for your project. Because of this integration, you can access real-time information about the electrical parts vendors and prices they are offering. This helps in making accurate purchase decisions quickly and saves your time.
