Twin Earth Wire Cable Electrical Wire 6242y Grey PVC Insulated 1.5MM 2.5MM
APPLICATION
Fixed Wiring in Buildings
Lighting Circuits: Primarily used for wiring lighting points in domestic, commercial, and industrial buildings. The 1.5mm² size is standard for this purpose.
Power Socket Circuits (Ring & Radial): The 2.5mm² size is commonly used for wiring 13A power socket outlets in both ring final circuits and radial circuits.
Fixed Appliance Connections: Used to supply power to various fixed appliances such as immersion heaters, boilers, and cookers (depending on current requirements).
FEATURES
Rated voltage: 300/500V, fully applicable to low-voltage power distribution systems in both household and commercial environments.
Long-term working temperature: Maximum +70°C
Flame retardancy: Standard PVC has self-extinguishing properties, meaning it will not continue to burn after being removed from a flame, which helps prevent the fire from spreading through the cable.

FAQ
Q: What is the primary use of Twin & Earth cable?
A: Its primary use is for fixed wiring in domestic and commercial buildings. It is not suitable for portable appliances, extensions, or outdoor use without additional protection.
Q: Can I use 1.5mm² and 2.5mm² cable for the same applications?
A: No. They are designed for different circuits:
• 1.5mm²: Typically used for lighting circuits.
• 2.5mm²: Standard for socket outlets (ring/radial circuits) and fixed appliances like immersion heaters.
Q: What is the maximum temperature this cable can withstand?
A: It has two key temperature ratings:
• Continuous Operating Temp: Up to +70°C.
• Short-Circuit Temp (max. 5s): Up to +160°C.
Q: Is Twin & Earth cable suitable for outdoor installation?
A: No. The standard grey PVC sheath is not UV resistant and can degrade outdoors. It is designed for dry internal locations. For outdoors, it must be protected within a suitable conduit or a special exterior-grade cable should be used.
Q: Why is there a bare copper wire inside the cable?
A: The bare wire is the Circuit Protective Conductor (Earth wire). It provides a vital safety path for fault current to flow, causing the circuit breaker to trip. It must always be connected to the earth terminal in accessories and consumer units.
