Terminal blocks, covers and consumer unit accessories for neat, compliant board builds and upgrades. This range includes 100A terminal blocks, cable glands, terminal covers, and blanking modules used to finish consumer units, meter boards, and enclosures properly.
Whether you're replacing missing parts on a maintenance job or specifying accessories for a fresh board build, these components help keep cable entry, termination, and spare ways tidy, protected, and inspection-ready.
Quick answer: If you're wiring or finishing a consumer unit, enclosure, or distribution setup, you’ll typically need the right terminal block, a suitable cable gland, and the correct blanking or cover accessories to keep the install safe, organised, and compliant.
Our range is built around the accessories electricians regularly need on site: 100A multi-way terminal blocks for clean terminations, terminal covers for safer finishing, glands for secure cable entry, and blanking modules for unused ways in boards and enclosures.

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.
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.
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.
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.
