Types of Conduit
Metallic conduit
RSC – rigid steel conduit
IMC – intermediate metallic conduit
EMT – electrical metallic tubing
RMC – rigid metallic conduit
FMC – flexible metallic conduit
LFMC – liquid tight flexible metallic conduit
RSC/RMC or IMC are commonly used conduit in service entrance
Non - metallic conduit
PVC - polyvinyl chloride
FMNC - flexible non - metallic conduit
Pull box, junction box, gutter box - is used for cable/wire pulling and termination
of wires.
Electricians knife - is used to avoid nicking of wire or lessen the number of
Conductor that will cause the wire heating up
Rubber - tape is commonly used in insulation bared conductor in outdoor
installation to avoid moistures.
Power tools
Electric hand drill
Electrical grinder (cause of break down worn out carbon brush)
Soldering iron
Heat gun
When using power tools during installation; check first if it is safety to use or in
good condition
Fittings that are used in installation of conduits
Conduit strap
Coupling condulet
Straight connector
Bushing
Locknut
Enclosure is a part of providing degree of protection of electrical device or
equipment against electrical hazard and to avoid direct contact to person with
live parts.

3 types of GFCI (ground fault circuit interrupter)
CB type
Receptacle type
Portable type
Purpose of using GFCI to prevent electrocution
GFCI, RCCB, ELCB, are all ground fault protection.
VOM/ volt, Ohm, milli - ammeter used to measure voltage, resistance and
current.
