Choosing the Right Terminal Block

- 100A power blocks – handle higher current demands. Example: 5-Way 100A Terminal Block.
- Pluggable terminal blocks – allow easy connection/disconnection for modular wiring
- Three-phase terminal blocks – designed for balanced connections across phases
- Distribution blocks – multiple ways for splitting or combining feeds
Applications
- Consumer units – tidy, labelled connection points for incoming and outgoing circuits
- Pump and motor installs – robust terminations for higher current equipment

FAQs
What size terminal block do I need?
Match the block to your cable size and current demand – e.g. 16mm² blocks for sub-mains, or 100A blocks for heavy-duty feeds.
Are pluggable terminal blocks worth it?
Yes – they save time in modular or repeatable installs where circuits need to be disconnected and reconnected regularly.
Can I use plastic blanks in a metal enclosure?
Yes – both metal and plastic blanks are compliant, but metal blanks are preferred for fire resistance where required by regs.
