Conduit installations
A conduit tube, channel pipe which insulated conductors are
contained.
Conduit supplied 3. Heavy gauge made from a
sheet steel welded along the seam form tube and used for most
electrical installation work.

STEEL CONDUIT
Steel conduits are made specification defined 4568 and are
either heavy gauge welded solid drawn. Conduit tubing and fittings are supplied black enamel finish
for internal use hot galvanized finish for use external damp instal-
lations.Basic Electrical Installation Work

Definition
A conduit tube, channel pipe
in which insulated conductors are
contained.24. 14. There are three types con-
duit used electrical installation work: steel, PVC and flexible. conduit
installation can rewired easily altered any time, and this flexibility,
coupled with mechanical protection, makes conduit installations popular
for commercial and industrial applications.

saddles pipe hooks, shown Fig. The conduit, effect, replaces the PVC outer sheath cable,
providing mechanical protection for the insulated conductors
