Grounding hardware Rittal 2566.000, earthing strap M8–M8, cross-section 25 mm², length 170 mm, yellow

Rittal 2566.000 grounding hardware Yellow is a short, pre‑assembled earthing strap designed to provide a reliable connection between enclosure earth screws. The product is colour‑coded yellow and comes ready to install with ring terminals sized for common earthing screw threads. With a compact length and a cross-sectional area suitable for equipment bonding, it simplifies creating a secure protective earth link.

Advantages

The earthing strap is supplied pre-cut and terminated with ring terminals to match M6 and M8 earth screws, reducing installation time and ensuring consistent contact. Its compact 170 mm length and robust conductor cross-section provide a tidy, low‑impedance connection suitable for many industrial and electrical enclosures. The yellow insulation makes the ground connection easy to identify during inspection.

Suitable for

• Making a secure earth connection between enclosure earth points or terminal studs
• Bonding panels, sheet metal parts and equipment inside electrical cabinets
• Use in industrial control cabinets, distribution boxes and machinery enclosures

When it may not be suitable

This short, fixed‑length strap is not designed for long‑distance grounding runs or where adjustable lengths are required; a longer cable or a flexible lashing method may be preferable. It is intended for general bonding and protective earth use—applications requiring certified high‑current or special grounding systems should follow project‑specific standards and use components rated accordingly.

Key specifications

• Colour: yellow insulation
• Length: 170 mm
• Weight: 280 g
• Ring terminal sizes: fittings for M6 and M8 earth screws
• Conductor cross-sectional area: approximately 25 mm²

How to use

Fit the ring terminals onto the corresponding earth screws and tighten to the manufacturer‑recommended torque for the enclosure hardware. Ensure contact surfaces are clean and free of paint, corrosion or debris for optimal conductivity. Route the strap without sharp bends or mechanical strain; secure as needed to prevent movement inside the cabinet.

What to consider before purchase

• Verify that earth screw thread sizes and spacing in your enclosure match M6 and M8 ring terminals
• Confirm the 170 mm length and 25 mm² cross section meet your bonding and current‑carrying requirements
• Check that yellow insulation colour and pre‑terminated design fit your installation and inspection practices

Usage recommendations

Use the strap only where the fixed length and terminal types match the enclosure hardware. For reliable long‑term performance, tighten terminals to specified torque, inspect contact points periodically, and replace if corrosion or damage is observed.
