The WTB5-GY is a 5 way 100A terminal block in grey, typically used for alternate phase identification in single-phase or three-phase systems. It provides a secure, tamper-resistant solution for splitting meter tails, connecting consumer units, or managing multiple outgoing circuits in residential and commercial installs.
Like the rest of the WTB5 range, it accepts conductors from 2.5 mm² to 35 mm² and includes a lockable, sealable lid with blanking inserts for unused terminals. The hexagon screw design delivers strong, vibration-resistant clamping - keeping connections secure in demanding environments.
Installer Tip: Use the grey variant when wiring alternate phases in three-phase systems. This helps maintain clear colour coding and compliance with wiring standards.
