Heavy Gauge Conduit System

Heavy Gauge Conduit System Points : heavy gauge conduit system Wiring an installation in conduit can be defined as running insulated cables in protective tubes from the supply to the load. Conduit is divided into two types — Class A which is plain light gauge steel, and Class B which is screwed heavy gauge steel. Light gauge conduit is described later in this section.

Class B screwed heavy gauge conduit is usually either black enameled or galvanised.

It generally made out of strips which are formed round and then welded, but it can be obtained solid drawn.

The Class 13 conduit system is very widely used for wiring installations, especially for modern commercial and industrial buildings. Its advantages are that it gives the cables good, mechanical protection permits easy rewiring when necessary, reduces fire risk to a minimum, and present a pleasing appearance if properly installed. The disadvantages are that it is expensive compared with some systems is liable to corrosion in acid fumes, and in excessive humidity moisture can condense inside the conduit.
