FAQS
Copper tube terminals are sized based on two key measurements: cable size (measured in mm²) and stud size (the diameter of the connection point). First, identify your cable size - this is usually printed on the cable jacket. Then, determine your stud size based on your equipment's terminal specifications. Our range includes cable sizes from 10mm² up to 150mm² with various stud sizes (10mm, 12mm, and more). If you're unsure, contact our team at 01582 606033 for guidance.
Our heavy-duty (HD) range is engineered for more demanding applications and higher tensile strength. The HD terminals are designed primarily for compression crimping onto European stranded and flexible cables, producing high tensile crimped joints in accordance with BS4G 178 Part 2 1986 and RSE/STD 024 Part 7 - Issue A (London Underground Approval E6487 A2). Standard terminals are suitable for general electrical connection applications. Heavy-duty terminals provide enhanced reliability for critical installations.
Yes. Copper tube terminals are corrosion-resistant, making them an excellent choice for both indoor and outdoor applications. They provide secure, reliable connections across a wide range of environments and temperatures.
All our copper tube terminals are manufactured from seamless copper tube to BSEN 12449: 2016. They fully comply with BS EN 61238-1-2003 and BS 4579. Each terminal is provided with an inspection hole to ensure the conductor is fully inserted before crimping, guaranteeing quality and reliability.
The inspection hole serves as a quality control feature. It allows you to verify that the conductor has been fully inserted into the terminal before the crimping process begins. This ensures a proper, secure connection and prevents installation errors.
To ensure a safe connection, strip the cable insulation to the length of the lug barrel. Insert the conductor fully into the cable lug, checking the inspection hole for correct placement. Finally, use a calibrated crimping tool to compress the barrel, creating a permanent, low-resistance bond.
