N0 Item Discriptions

1. MCB (MINIATURE CIRCUIT BREAKER) rated current not more than 100 A. Trip

characteristics normally not adjustable.

Thermal or thermal-magnetic operation.

Breakers illustrated above are in this

category.

2. RESIDUAL CURRENT CIRCUITBREAKER(RCCB)

Residual Current Circuit Breaker (RCCB), is

an electrical wiring device that disconnects a

circuit whenever it detects that the electric

current is not balanced between the

energized conductor and thereturnneutral conductor. Such an imbalance

is sometimes caused by current leakage

through the body of a person who is

grounded and accidentally touching the

energized part of the circuit.

A lethal shock can result from these

conditions. RCDs are designed to

disconnect quickly enough to mitigate the

harm caused by such shocks although they

are not intended to provide protection

against overload or short-circuit conditions.3. NEUTRAL LINK It is a joint in the neutral connection that can

be opened

essentially it's for testing purposes only.

4. KILOWATT-HOUR METER

is a device that measures the amount

ofelectrical energy consumed by

a residence,business, or an electrically

powered device.Electric meters are typically

calibrated in billing units, the most common

one being the kilowatt hour. Periodic

readings of electric meters establishes billingcycles and energy used during a cycle.

5. MAIN SWITCH is used to make sure that an electrical circuit

can be completely de-energized for service

or maintenance. MAIN switches are used in

electrical substations to allow isolation ofapparatus such as circuit breakers and

transformers , and transmission lines, for

maintenance

6. 1 WAY SWITCH A simple on-off switch: The two terminals

are either connected together or

disconnected from each other. An example isa light switch.

7. 2 WAY SWITCH A simple changeover switch: C (COM,

Common) is connected to L1 or to L2.

8. INTERMEDIATE SWITCH DPDTswitch internally wired for polarity-

reversal applications: only four rather than

six wires are brought outside the switch

housing; with the above, B is connected to F

and C to E; hence A is connected to B and D

to C, or A is connected to C and D to B.

9. FUSE a device used in electrical systems to

protect against excessive current.

10. FAN REGULATOR Regulates the electrical currents for house

fan.it can regulates from minimum to the

maximum capasities of current that the fan

motor can handle.some fan regulator have

setup by a number of speed depend of its

motor

11. OUTLET SOCKETS 13A for removably connecting electrically

operated devices to the power

supply.An electric plug connects

mechanically to a matching socket. Usually

plugs are movable connectors, and sockets

are fixed to equipment.

12. MOUNTING BOX Are use for mounting many accessories in

electrical installation. Many accessories for

electrical instal are designed to fit into the

mounting boxes defined in BS 5733:1995 -

Specification for general requirements for

electrical accessories, with an

86 mm86 mm square face plate that is fixedto the rest of the enclosure by

two M3.5 screws (typ. 25 mm or 40 mm

long) located on a horizontal center line,

60.3 mm apart. Double face plates for BS

5733 boxes measure 147 mm86 mm and

have the two screws 120.6 mm apart.lations

(e.g., wall sockets, switches)

13. END BOX End box can be use for mounting electrical

installation such as lamp holder,its also use

for storing excess cables for further use.

14. SPRING CLIP SADDLE The spring clip saddle is use for clipping pvc

pipe.its a middle jointer between walls and

pipes.

15. LAMP HOLDER A device which mechanically supports a lampfor the purposes of making electrical contact

with the lamp.

16. DISTRIBUTION BOARD A distribution board (or panelboard) is a

component of an electricity supply system

which divides an electrical power feed into

subsidiary circuits, while providing a

protective fuse or circuit breaker for each

circuit, in a common enclosure

17. DISTRIBUTION FUSE BOX Smaller than distribution board,fuse box is

use for containing RCCB,MCB,Main

Switch,Neutral link and etc..,

18. COMBINATION PLIERS a type ofpliers used by electricians and

other tradesmen for gripping small objects,

to cut and bend wire and cable

19. SCREWDRIVER is a tool for driving screws and rotatingother machine elements with the mating

drive system. The screwdriver is made up of

a head or tip, which engages with a screw,

a mechanism to apply torque by rotating the

tip, and some way to position and support

the screwdriver
