Earthing Clamp Design – Precision for the 310 Series
Each 310 enclosure is compatible with the dedicated
Wiska EC310 Earthing Clamp — a brass 3 × 20 mm plate developed for this range.
It ensures secure earthing continuity without compromising the IP seal, creating a complete, compliant solution for professional installers.
Compatible Cable Glands and Accessories – Guide to Wiska 310 COMBI Boxes
For a fully sealed, regulation-ready setup, use genuine Wiska accessories:
- Wiska SWA Cable Glands – brass / nickel-plated glands for armoured cables.
- Wiska Nylon Cable Glands – lightweight, corrosion-resistant options for indoor use.
- Outdoor Electrical Cables – UV-resistant cables for lighting and external power installations.
Together, these components create a fully compatible Wiska system from junction to termination.
Available With or Without WAGO Connectors
