Experts in professional equipotential bonding
At Electricon, we are experts in professional equipotential bonding, where we guarantee exceptional quality. The execution of equipotential bonding requires specialized knowledge, as there are specific requirements that we at Electricon have full insight into. We are well versed in various installation environments where equipotential bonding is required and have in-depth knowledge of the requirements for bonding and the selection of components.
By choosing Electricon as your advisor, sparring partner, or contractor for bonding connections, you gain a partner with extensive experience in installing equipotential bonding across all types of environments, construction projects, and industries.
Let us begin the dialogue with a non-binding conversation about your task, so that we can best help you move forward.
Equipotential bonding prevents voltage differences and dangerous situations
Equipotential bonding refers to a concept that is increasingly seen in many different types of installations. Equipotential bonding means that two conductive parts are connected in order to avoid a voltage difference in the event of a fault, short circuit, lightning strike, or possible electrostatic charging. The bonding connection must ensure that no dangerous touch voltage can occur – or a voltage so high that a spark could potentially jump.
Types of equipotential bonding
Protective equipotential bonding in accordance with DS/HD 60364
Protective equipotential bonding was previously referred to as “main bonding” – and today it must be carried out in every electrical installation, something we at Electricon are happy to assist with. Protective equipotential bonding includes all incoming metallic parts that may introduce a dangerous voltage and that are not directly part of the electrical system.
Examples of metallic parts include:
- Pipes entering the building from outside, such as water, heating, gas, etc.
- Extraneous conductive parts
- Accessible reinforcement in concrete structures
These metallic parts must be bonded to the overall protective equipotential bonding at the point where they enter the building. There are clamps and connection components available for all types of equipotential bonding, and Electricon is happy to assist with dimensioning and selecting the appropriate solution.
The protective equipotential bonding must be connected to the installation’s main earthing terminal via bonding conductors in accordance with section 544.1, where 25 mm2 copper is the maximum cross-section.
Supplementary protective equipotential bonding in accordance with DS/HD 60364
Supplementary protective equipotential bonding in a building installation includes additional bonding between exposed conductive parts of fixed equipment and extraneous conductive parts, including metallic reinforcement in concrete structures.
There are requirements for supplementary equipotential bonding in the following areas of an installation in accordance with DS/EN 60364 – Part 2:
- Bathrooms
- Swimming pools and fountains
- Agriculture and horticulture
- Conductive locations with restricted movement
- Medical locations
- Areas for keeping animals at marketplaces, amusement parks, circuses, and similar locations
The supplementary equipotential bonding must be carried out by connecting the local protective conductor potential to the extraneous conductive parts in the area. The requirement is often limited to 2.5 mm2 copper with mechanical protection of the conductor.
Lightning equipotential bonding in accordance with DS/EN 62305-4
In a lightning protection system, as a supplement to the installation-related equipotential bonding that is carried out in every electrical installation, additional lightning equipotential bonding must be performed for, among others, the following system components:
- Reinforcement in cast concrete structures for columns, shafts, walls, and floor slabs
- Elevator equipment (can advantageously be bonded to the reinforcement in the elevator shaft)
- Ventilation systems
- Cable routing systems
- Piping systems for sprinklers, water, heating, gas, etc.
- Conductive façade systems
All of these bonding connections must be connected to the overall protective bonding system and ultimately connected to the same main earthing terminal.
ATEX-potentialudligning iht. DS/EN 60079-14
In explosion-hazardous installation environments with ATEX-classified zones, comprehensive equipotential bonding must be carried out. The standard is incorporated into Danish legislation and must therefore be regarded as a legal requirement that it is fully complied with. Different methods must be applied depending on the classification and the specific situation.
