Things to know about building wire

Building wires as indoor electrical wire

Are you looking for building wire types for electric installations in your home? Then Faber is the right place for you! In our online shop you can find powerful, quality-tested sheathed wires by the metre. Depending on your need and area of application, we have 3-core and 5-core building wire definitions in a variety of cross-sections, such as residential electrical sheathing 3x1.5mm², building wire 5x1.5mm² or building wire 5x2.5mm².

Areas of application for outdoor electrical wire 3x1.5mm², 5x1.5mm² and 5x2.5mm²

Building wires of type NYM-J are robust PVC sheathed cables. They can be used universally in many areas of electrical wiring installations. The cables’ name is derived from the German terminology for N = standard line, Y = PVC isolation of the cores, M = sheathed cable, J = with protective conductor.
The most common 3-core cable is the building wire 3x1.5mm², the most commonly used 5-core cables are building wires 5x1.5mm² and 5x2.5mm². Cables with a conductor cross-section of 1.5mm² can be used for wiring electrical light and socket circuits. For appliances with a higher electricity consumption, such as dishwashers, microwaves or tumble dryers, cables with a conductor cross-section of 2.5mm² are recommended.
Faber’s diverse product portfolio also offers halogen-free building wires for places with a high concentration of people and material assets, with improved behaviour in case of fire. In addition, we have shielded zero-halogen sheathed wires for electric installations in sensitive environments such as IT departments or hospitals. These building lines are equipped with a static shield to limit the electro-magnetic fields of electrically charged conductors in these environments, but can also be used in residential buildings where sensitivity to electro-magnetic fields is a particular concern.

Laying building wires

Building wires can be laid on, above, in or under render in dry, moist or wet rooms, in brickwork or concrete. The only exception is direct embedding in churned, vibrated or tamped concrete. Routing underground or exposing the cables to direct sunlight is not possible. Laying the cables without an installation tube is generally more cost-effective, but has the disadvantage that conductors cannot be replaced or changed at a later stage.
