What Are Terminal Blocks?
Terminal blocks (sometimes called connector strips or terminal boards) provide a safe way to join multiple wires while keeping circuits organised and compliant. They are widely used in consumer units, distribution boards, and control panels.
Types of Terminal Blocks
- Screw terminal blocks – simple, secure terminations for residential installs
- DIN rail terminal blocks – clip directly into consumer units and panels
- Three-phase terminal blocks – distribute balanced loads across phases
- High-current & 100A blocks – built for mains or sub-distribution. Popular choice: 5-Way 100A Terminal Block.
- Modular & pluggable blocks – allow fast installation and easy expansion
Applications
- Board builds & rewires – organise circuits neatly and safely
- Commercial distribution – higher current and three-phase terminations
- Control panels – modular connectors for industrial applications
- Maintenance – quick replacements or upgrades during site callouts. Handy with MCB blanks and cable glands.
FAQs on Terminal Blocks
Are terminal blocks safe for mains wiring?
Yes – provided they are rated correctly. Many blocks are designed for 100A+ and are fully BS EN compliant.
What’s the difference between a terminal block and a connector strip?
They perform the same function. Connector strips are usually simple screw-down types, while terminal blocks also include DIN-rail and modular designs.
Can I use plastic terminal blocks in a metal enclosure?
Yes – both metal and plastic blocks are compliant. Just ensure correct cable sizing and secure fixing.
