5 Electrical Wiring Systems for Houses

Casing and Capping Wiring System

This type of wiring system is obsolete today. It uses VIR, PVC, or some other kind of insulated cable.

Cleat Wiring System

PVC wires and ordinary VIRs are compounded by braiding together fixing on the ceilings and walls using porcelain cleats with plastic, grooves, or wood. This wiring system is temporary which makes it unsuitable for heavy-duty domestic use.

In lead sheathed wiring, conductors insulated with VIR are used. These conductors are covered with an external sheath of lead and aluminium alloy to protect cables from atmospheric corrosion, moisture, mechanical damage.

Conduit Wiring System

Conduit wiring is the most common type of wiring used in homes these days and it has two types.
