- Product Details
2.5 mm cable is a low voltage cable commonly used in house wiring systems. Its conductor is made of high-precision oxygen-free copper with stable electrical conductivity. The insulation is made of PVC, which is sufficiently abrasion and tear resistant. 2.5 mm2 single copper core cable can carry a higher current of about 20 amps compared to 1.5mm cable. It is suitable for laying in fixed positions in concealed installation through pipes and is commonly used for sockets, power sockets and mains wiring in lighting circuits.

FAQ
What is the current carrying capacity of 2.5mm house wire?
A standard 2.5mm² Twin & Earth cable can carry approximately 27 Amps when clipped directly to a surface (Method C). If installed in conduit or thermal insulation, this rating drops to around 20 Amps.
What is 2.5mm wire mainly used for?
It is the standard cable for domestic socket circuits. It is most commonly used in 32A Ring Final Circuits (Ring Mains) to power wall outlets, or in 20A Radial Circuits for specific appliances like immersion heaters or small air conditioners.
Can I use 2.5mm wire for lighting circuits?
Yes, but it is uncommon. Standard lighting circuits typically use 1.5mm² cable (protected by 6A or 10A). Using 2.5mm is technically safe but makes termination into small light fittings and switches difficult and unmanageable due to the stiffness of the wire.
