Computer Aided Design (CAD)

• Single-line diagrams: are the most basic type of electrical drawing. They show all the main electrical components of a system, such as the power source, the distribution panels, and the major circuits.
• Wiring diagrams: show the details of how the electrical components are wired together. They are used to troubleshoot electrical problems and to plan new electrical installations.
• Schematic diagrams: illustrate the electrical components of a system in more detail than single-line diagrams. They show the symbols for the electrical components, as well as the connections between them.
• Pictorial diagrams: present the electrical components of a system in a three-dimensional view. They are often used to show the installation of electrical components in a building.
• Layout diagrams: highlight the location of electrical installations in a building and are used to plan the installation of electrical components and troubleshoot electrical problems.

Yes, there are multiple UK standards that electrical drawings need to be compliant with, including:

• BS 7671:2018 – Requirements for electrical installations. This standard sets out the requirements for the design, installation, and maintenance of electrical systems in the UK.
• BS EN 61082-1 – Symbols for electrical installations. This standard specifies the symbols that should be used in electrical drawings.
• BS EN 60617-1 – Graphical symbols for use in electrical diagrams. This standard specifies the graphical symbols that should be used in electrical drawings.
• As well as these standards, electrical drawings may also need to be compliant with local regulations, for example, the UK Building Regulations. These regulations set out requirements for the electrical safety of buildings.

Our team of specialists can tell you which of the specific standards and regulations apply to your site, ensuring your electrical drawings are compliant with them.

Wiring and electrical schematic drawings are both tools key to electrical design, but they’re used for different purposes.

Wiring diagrams show the physical layout of an electrical system, including the location of all the electrical components and the connections between them. They are used to troubleshoot electrical problems and to plan new electrical installations.

Electrical schematic diagrams show the electrical components of a system in more detail than wiring diagrams. They show the symbols for the electrical components, as well as the connections between them. They are used to understand how an electrical system works and to troubleshoot electrical problems.
