4mm house wire is a high quality electrical wire designed for residential and light commercial electrical systems.The 4mm² cross sectional area is suitable for indoor wiring, outlet connections, lighting circuits and powering appliances. It features a 99.9% oxygen-free copper conductor (OFC) and flame-retardant PVC insulation to ensure superior conductivity, safety and durability. The ZW household wire manufacturer offers a range that complies with IEC 60227 and BS 6004 international standards.

Key Features

1. Stranded structure, small bending radius. It can be easily wired through the pipe and reduce the difficulty of construction.
2. Fireproof; insulation voltage resistance (450/750V); acid and alkali corrosion resistance.
3. Customized PVC or LSZH (Low Smoke Zero Halogen) jacket to enhance mechanical protection for complex environments (such as buried walls, through the pipe).

FAQ

A standard 4mm² Twin & Earth cable can carry approximately 37 Amps when clipped directly to a surface (Method C). However, if installed in thermal insulation or a conduit, this rating de-rates significantly (often down to 25-30 Amps). Always check local regulations like BS 7671.
It is primarily used for high-power radial circuits. Common applications include connecting electric cookers/ovens, water heaters, and powering heavy-duty air conditioning units. It is also used for radial socket circuits where a higher load capacity than standard 2.5mm wire is needed.
Yes, but usually in a Radial circuit configuration, protected by a 32A breaker. It is generally too thick to use in a standard Ring Final Circuit (which uses 2.5mm), as terminating two 4mm cables into a single socket terminal is physically difficult.
