A fast-changing surge current can create voltage across the inductance of a bonding lead. This makes routing and length relevant to protection performance.
How it works in practice
Follow the installation guide for direct routing, conductor dimensions and attachment. Avoid loops or unnecessary detours. The whole bonding system matters, so a short local wire cannot compensate for an unsuitable connection point. Use a qualified installation design for the site.
Example and interpretation
Two conductors with similar DC resistance can behave differently during a fast transient if their layouts differ.
Checks before use
- Use the documented conductor
- Route directly
- Avoid loops
- Verify the bonding point
Important limit
Do not estimate transient protection solely from a DC ohmmeter reading.
