The WTB5-GN is a 5 way 100A terminal block in green, designed for earth and bonding connections in residential, commercial, and small industrial installations. With a rating of 100A and capacity for 2.5 mm² to 35 mm² conductors, it provides a safe, tamper-resistant way to terminate and split bonding cables, earth tails, and protective conductors.
Like all WTB5 variants, it features a lockable, sealable lid with blanking inserts for unused ways. The hexagon screw clamp design ensures strong, vibration-resistant connections. The green housing provides clear visual identification for earth bonding points, aiding compliance with UK wiring regulations.
Installer Tip: Use the green variant exclusively for earthing and bonding conductors. Always torque to 3 Nm and apply a DNO seal where bonding security is required.
