Nova 4mm wire is a 4.0 mm², 450/750 V single-core copper wire cable with a stranded conductor, built for the heavy circuits in house wiring – air conditioners, electric geysers, ovens, water motors and sub-main lines. With about 34% more copper than 7/29 wire, it carries 32 A in conduit (BS 7671, 30 °C), runs cooler under load and keeps voltage drop low on long runs. It comes in five colours – red, black, green, yellow and blue – so phase, neutral and earth stay clearly marked in your electric wiring. Order Nova electric wires online from Ghar Plans, with delivery across Pakistan and practical advice from a team that designs and builds houses.
