Terminal Blocks & Board Accessories for Tidy, Compliant Installs
Terminal blocks and related accessories help bring order to consumer units, distribution boards, and enclosure builds. They give you secure connection points, cleaner cable management, and a more professional finish when you're terminating tails, blanking spare ways, or protecting cable entry points.
What You’ll Find in This Range
- 100A terminal blocks – useful where higher current capacity and multi-way termination are needed. A common choice is the 5-Way 100A Terminal Block.
- Terminal covers – added protection where exposed terminations need a safer finish.
- Cable glands – designed to secure incoming cables and improve cable entry into boards and enclosures. See the tails gland.
- Blanking modules – ideal for covering unused outgoing ways and keeping boards tidy. See the 1 Module Blanking Plate.
Typical Applications
- Consumer unit upgrades – replace missing blanks, improve termination layout, and tidy cable entry
- New board builds – fit the right block and accessory set from the start for a cleaner install
- Meter and tails work – use suitable terminal and gland accessories where secure, organised connection points are needed
- Three-phase and larger enclosures – support heavier-duty terminations and accessory fit-out where standard parts are not enough
Choosing the Right Terminal Block or Accessory
The right choice depends on the cable size, current rating, and where the component is being used. For example, a 100A terminal block makes sense for heavier-duty feeds and multi-way termination, while a simple blanking module is there to finish unused ways cleanly in a board. For cable entry, the right gland size matters just as much as the board itself.
Used Alongside Consumer Units, Enclosures & Protection Devices
These accessories are rarely bought in isolation. They’re commonly specified alongside consumer units, consumer unit enclosures, metal enclosures, and broader circuit protection devices. For larger setups, see our three-phase boards & accessories range.
FAQs on Terminal Blocks & Accessories
What is a terminal block used for?
A terminal block provides a secure connection point for one or more conductors. In board and enclosure work, it helps keep terminations organised, accessible, and properly contained.
When would I use a 100A terminal block?
A 100A terminal block is typically used where higher current capacity is needed, such as heavier feeds, sub-main connections, or multi-way distribution inside an enclosure or board setup.
Do I need blanking modules in a consumer unit?
If there are unused ways, blanking modules help finish the board properly and maintain a tidier, safer front face.
Why use a cable gland instead of feeding cable straight through?
A gland helps secure the cable at the entry point and creates a neater, more robust finish, especially where tails or larger incoming cables enter an enclosure.
