BARGAINSER
Bargainser is a tool that serves
as an electrical power strip that goes into houses, it also serves as a measure
of the amount of electric power house was used (in kWh). There are various restrictions
issued by PLN's power for residential consumption, which is 220 VA, 450 VA, 900
VA, 1,300 VA and 2,200 VA.
In bargainser there are three
main parts, namely:
- Or Miniature Circuit Breaker
MCB, serves to cut off electrical power automatically if the power is delivered
exceeds the limit value. MCB this is an on / off and can
also serve as the main switch in the house. If the MCB bargainser is in the
off condition, then the entire flow of electricity in the house was stopped. The switch is normally turned
off when the electrical installation repairs will be done at home.
- Electric Meters or kWh meter,
this instrument serves to measure the amount of power used by residential
houses are in units of kWh (kilowatt hour). In bargainser, electric meters
tangible series of numbers in an analog or digital that will change according
to the use of electric power.
- Spin Control, a control device
power usage in the residence and will always be spinning as long as there
electrical power is used. Turnover spin control will be
semakain quickly if electric power is used the greater, and will slow down if
the power is used less / less.
At the output channel Bargainser
usually there are 3 wires, ie the phase wires, neutral wire and ground wires
are connected to the ground. Of electricity should be
connected with bargainser first before going into residential electrical
installations.
ELECTRICAL SAFETY
Residential electrical
installation also requires a security that serves to disconnect the electrical
circuit when an interruption in the residential electrical installations, such
as the interruption of short circuit or short circuit or shorted.
There are two types of
electrical safety in residential electrical installations, namely:
- Safety ordinary or so-called
melting fuses, safety devices are working to decide how to merge the electrical
circuit with a wire that is placed on a tube when the wire is dialairi electric
current of a certain size.
- Safety thermic power, commonly
called the MCB and is a safety device that will decide the electrical circuit
based on the heat.
Switches
The switch or switches is a
component of an electrical installation that serves to connect or disconnect
the electricity at a pemghantar.
Based on the magnitude of the
voltage, the switch can be divided into:
- Low-voltage switches.
- Medium voltage switches.
- Switch high voltage and very
high.
While based on the place and its
installation, the switch can be divided into:
- The switch in-bow, which is
planted in the wall switch.
- Switch out-bow, the switch is
mounted on the wall surface.
The next switch types can be
distinguished by function, namely:
- Switch on-off, a switch that
works to connect the electrical current if the button is pressed on the on
position. To disconnect the electric
current, the switch must be pressed in the off position. The switch of this type usually
used for the light switch.
- Push-on switch, a switch that
connects the electrical current if the button is pressed at the position on and
it will automatically cut off electrical current, when the button is released
and returns to the off position by itself. Usually this type of switch used
to switch the bell house.
Based on the type of per-unit,
the switch can be divided into two types, namely:
- Single switch, a switch which
only has one input channel connected to a power source, and output channel
connected to the electrical load / power tool use.
- Switch compound, is a switch
that has one input channel connected to a power source, but has a lot of output
channel is connected with some of the load / power tools are used. Number of output channel depends
on the number of buttons on the switch.
STOP CONTACT
Outlets, some say the outlet, an
electrical component that serves as a mouth of the relationship between the
electrical appliance with electrical flow. In order for an electric
appliance connected to an electrical outlet, then the necessary cables and
plugs or plugs that will be plugged in the socket.
Based on the shape and function,
the socket can be divided into two kinds, namely:
- A small receptacle, a socket
with two holes (canals) which serves to supply power at low power to electrical
devices through the plug which is also a small type.
- Stop great contacts, also
nerupakan socket with two AC channels are equipped with a metal plate on top
and bottom sides of canal that serves as an air conditioner ground.sakelar this
type typically used for greater power.
While based on the place of
installation. There are two types of outlets,
namely:
- The socket in the bow, is a
terminal which is installed inside the wall.
- The socket bow out, which is
installed outside the wall or simply placed on the surface of the wall socket
when it functions as a portable.
Plug
Staker or a plug or sometimes
commonly called an outlet, because it is in the form of two metal plugs and an
electrical device that serves to connect the power tool with the power, plugged
in the outlet channel so that the electrical appliance can be used.
Based on the function and form,
the plug also has two types, namely:
- A small plug, a plug used to
connect electrical devices low-power, such as a lamp or small radio, a power
source or outlet.
- The plug is large, is a plug
that is used for power tools are helpless large, such as refrigerators,
microwaves, washing machines and others, with the power source or outlet. The plug type is equipped with a
metal plate to the canal that serves as a safety ground.

SOCKET, please read the article here.
CABLE
The power cord is an electrical
component that serves to deliver electrical energy to the sources of electrical
load or power tools.
For residential electrical
installation, the cable type used is usually as follows:
- HIS, this type of cable is PVC
insulated electrical wire and cored / contains a single wire. Air or cable type is not planted
in soil. The power cord is usually red,
black, yellow or blue. Penghantarnya wire insulation is
only one layer, so it is not strong enough to friction, gencetan / pressure or
animal bites such as mice. Because of the weakness in the
insulation is then required in the installation by using the outer coating of
PVC pipe or metal conduit.
- NYM, a PVC insulated
electrical wire and cored wire is more than one, there are 2, 3 or 4. Type of aerial cable with outer
insulation color is usually white and color isolation in different parts,
because the insulation is double the power cables NYM is relatively more robust
against friction or gencetan / pressure.
- NYY, this type of electrical
wiring is PVC insulated wires, cored 2, 3 or 4 with the color black outer
insulation. This type of ground wire, so
impervious to water and gencetan or pressure.
- NYMHYO, this type of cable is
a stranded cable with a core consisting of two pieces of two colors. This type of cable commonly used
in loudspeaker, sound system, lights a small to moderate power.
Similarly, the introduction of
equipment at a glance-electrical equipment for residential electrical
installations, information functions, shape / construction and workings of each
tool is a general explanation.
