## Summary description

Rittal DK 7549.000 is a pack of 10 earthing/grounding busbar extension elements intended for use in enclosure and switchgear installations. The kit supplies additional busbar sections to extend grounding connections, facilitating safe equipotential bonding and simplifying wiring in electrical cabinets and control panels.

## Long description

Rittal DK 7549.000 is a pack of 10 earthing/grounding busbar extension elements designed for enclosure and switchgear installations. These extension sections allow installers to extend the main grounding busbar vertically or horizontally inside electrical cabinets and control panels, providing additional contact points for equipotential bonding and cable terminations while maintaining a compact footprint.
Advantages
The kit provides ten identical busbar extensions that are compatible with standard Rittal enclosure earthing systems, enabling consistent mechanical and electrical connections. Using matched extension elements reduces installation time by simplifying alignment and mounting, and supports reliable conductive continuity across multiple panels. The uniform design helps maintain neat cable routing and reduces the need for improvised grounding solutions.
Suitable for
Extending grounding/earthing busbars in electrical enclosures and switchgear
Creating additional equipotential bonding points for control panels
Industrial and commercial electrical distribution cabinets
Retrofitting existing panels where extra busbar length is required
When it may not be suitable
This extension kit is intended for use with compatible enclosure earthing systems and may not fit non-standard or proprietary busbar designs. It does not include fasteners, mounting rails, or accessories that may be required for specific enclosure types; installers should verify mechanical compatibility and supply any missing parts separately.
Key specifications
Quantity: 10 identical busbar extension elements
Function: earthing/grounding busbar extension for enclosures
Typical installation: vertical or horizontal extension inside cabinets and switchgear
Application environment: electrical enclosures, control panels, switchgear rooms
How to use
Installers mount the busbar extension elements adjacent to the existing grounding busbar within the enclosure, ensuring firm mechanical contact and conductive continuity. Sections are positioned and secured according to the enclosure manufacturer’s instructions and local electrical standards. After mechanical attachment, connect the grounding conductors and verify continuity with appropriate testing equipment to ensure effective equipotential bonding and low-resistance connections.
What to consider before purchase
Confirm mechanical compatibility with the enclosure earthing system and available mounting space
Verify that the busbar cross-section and material meet the required current-carrying and grounding specifications for the installation
Check whether additional mounting hardware or accessories are needed and source them if not included
Ensure compliance with local electrical codes and grounding practices
Usage recommendations
Use these Rittal busbar extensions in combination with proper mounting and testing procedures: secure each section firmly, attach grounding conductors with appropriate terminals, and confirm low-resistance continuity after installation. For complex or high-current systems consult relevant standards or a qualified electrician to determine correct sizing and arrangement.
