Troubleshooting
Wire will not fit in terminal
Ensure the wire gauge is not larger than 2.5mm and that you are using a standard domestic twin and earth cable.
Lid does not close fully
Check that the wires are dressed neatly inside the housing and are not pushing against the lid mechanism.
Loose connection after installation
Re-open the box and verify that the terminal screws are tightened down firmly onto the copper conductors, not the insulation.

Setup, Compatibility & Care
Before starting, always turn off the power at the main consumer unit. Feed your cables through the entry points of the box and strip the insulation to expose enough copper to make a solid connection within the terminal block. Secure each wire tightly with the provided screws. Ensure the lid is properly seated and screwed down to protect the internal connections from dust and accidental contact. Periodically, if the box is accessible, check that the mount remains secure. This box is not waterproof, so it should only be used in dry, indoor environments.
