The WTB5-BR is a 5 way 100A terminal block in brown, typically used to identify live connections in single-phase and three-phase systems. Designed for safe, neat, and secure electrical terminations, it accepts cables from 2.5 mm² to 35 mm², making it ideal for splitting meter tails, feeding distribution boards, or managing multiple circuits in residential and commercial installs.
The block features a lockable, sealable lid for tamper-resistant use and includes blanking inserts to safely cover unused terminals. A hexagon screw clamp design ensures strong, vibration-resistant connections. Colour-coded variants simplify circuit identification, with brown recommended for live feeds in compliance with wiring regs.
Installer Tip: Use the brown variant to clearly mark live connections when splitting meter tails or feeding consumer units. Always torque to 3 Nm and seal the lid if required by the DNO.
