Electricity labelling symbols

Electrical labelling symbols are an essential part of electrical safety and clear communication in electrical installations. They are used to identify cables, wires, components and other elements of an electrical system, providing important information to electricians, maintenance personnel and others working on or using electrical systems.

Benefits of electricity labelling symbols

  • Helps to identify hazards and avoid accidents.
  • Provides information in a universal language that everyone can understand.
  • Quick and easy to identify information.
  • The same symbols are used in most countries.
  • Can be used to mark different types of electrical hazards.
  • Cheap way to improve security.

Different types of electricity labelling symbols

In our range you will find the following types of electrical labelling symbols:

  • Lightning in triangle warning of high voltage and electrical danger. This symbol is essential to mark dangerous areas and ensure that the right precautions are taken.
  • Earth symbol in circle used to mark earth connections. This symbol is important to ensure proper earthing and reduce the risk of electrical faults.
  • Earth sign without circle also used to indicate earth connections. It is flexible and can be used in different contexts where earthing needs to be marked.
  • Symbol L1 identifying the first phase of a three-phase system. Clear labelling of phases is critical for the safe operation and maintenance of electrical systems.
  • Symbol L2 identifying the second phase of a three-phase system. Labelling all phases correctly is essential to avoid confusion and ensure a safe installation.
  • Symbol L3 identifying the third phase of a three-phase system. With all phases correctly labelled, it is easier to monitor and maintain the electrical system.
  • Symbol PE which stands for protective earth and is used to mark protective earth conductors. This symbol is important to ensure that all protective earth connections are correctly identified.
  • Symbol PEN combining the functions of protective earth and neutral conductor. This symbol is used in systems where the PEN conductor is a critical part of the installation.
  • Sign N marking the neutral conductor in electrical systems. Clear labelling of the neutral conductor is important to ensure correct connection and operation.
