The terms point in the light Installation :

1. installation is an electrical channel, including the tools thatwere installed in / or outside the buildings for the electriccurrent after manyalurkan / or in the back of the planeboundary / meter owned company (PLN).

2. Electrical equipment is the planes, tools, motors, and whichcan be connected perlengkapanya or connected to theinstallation.

3. Home delivery connection is below ground or above ground,

including his tools up to the barrier plane / meter ownedcompanies that distribute electricity from low voltagedistribution network to the installation.

4. Group is part of the installation in its own secured with astream of aircraft safety.

5. Control aircraft is an aircraft that monitor usage and other units ofmeasure Volt, Ampere, Hertz and Cos .

6. Barrier aircraft is an aircraft that restrict the use of electric current

fuse antaralain-Automatic and a mini-circuit-breaker (MCB).

7. Meter is a measuring aircraft and shows the number of electricity

used, among others Watt-Hour, Volt-Ampere Hour (Var-Hour) and

Volt-Ampere Hour.

8. Current security is the securing of a plane installation and / or parts

thereof, of more current and / or short circuit currents include

miniature circuit-breaker and fuse.

9. Installers is the Indonesian legal entities listed on the company and

get approval and permission to work from the company to plan and

work on a network installation or installation work within the

company.

Lamp switches in the light Installation

Switches used to connect and disconnect the electricalcircuit.

Switch must be installed such that:

1. Moving parts are not stressed at the time the switch is open,

2. The position of all switches in an installation shall be uniform as all

switches connected in a state if the leg is pushed to the top or if the

upper leg in the press,3. Connecting terminals on the switch and the contact box, should not

be used for more than 1 core, except for those connecting terminals

specially made also to connect.


18/32


Terms of Use and Installation of Grid Contact:

1. Box wall contact one phase must be such that the contact wasneutral on the right (PUIL 1987),

2. Contact of the walls should be installed on the wall of at least 1.20m above the floor, except the contact box closed (PIL 1978, article

2, paragraph 14c),3. Contact box mounted on the bottom of the gap should be a box-

contact with the special construction (PIL 1978, article 2,paragraph 14d),

4. Contact box with a security wall fitted with a safety delivery (PUIL1987),

5. In a room equipped with a contact box with security contactsshould not be installed without any contact contact Kotal securityunless the contact box for low voltage for the separation of securityand safety (PUIL 1987), and

6. The ability to contact the box at least according to the power toolconnected to him, but not be less than 5A (PUIL 1987).

Lighting Installation One Phasa Two Groups

Lighting installations with the number of group lots of 6

(six), the number of points of light in a group of no more

than 15 (fifteen) (PIL 1978, article 2, paragraph 4).

An installation for lighting, where there is a box-contact

with the number of points of light is less than 15 (fifteen), if

possible divided into 2 (two) groups (PIL 1978, article 2,

paragraph 6)

Main Provisions of lighting installation

1. Installation of cables in the pipe, the pipe must be

installed first, then followed the cable (RA-HIS) waspulled into the pipe

2. To replace the cable, must be done without

dismantling the pipes

3. Provisions in number 2 above does not apply to cablewith 10mm2 cross section to the top, with a note of the

wiring visible when viewed and easily accessible.


25/32


4. Pipes may be used is a steel pipe from wear or no

connection with the elongated screw or selorok connection

and plastic pipes

5. To make a steel pipe bends, the terms are as follows:- The max diameter of 16 mm 2 -radius = 4 x pipe

- Diameter above 16 mm 2, the radius = 6 x pipe

- For plastic pipe with a 3 x = pipe

6. Withdrawal of the cable to pull through the box and thebox used to connect connector or pull by using the PA or

lasdup isolation and / or the like


26/32


7. Between the two pull boxes should be three things bends or

straight pipes as far as 20 m. End of the pipe must be equipped

with a safety ring (net) and maximum distance of the pipe

clamp 1 m

8. Use pipe connection using the following ways:

On the horizontal pair, the connection must be under and in

vertical pairs, the connection must be on the walls.

9. Switches and contacts should be mounted as high as between

1.2 m and 2 m from the floor;

10.Cable types such as GRLL, NBEU and NYM, may be installed

without the pipe and inside the walls;


27/32


11.Installation setting inside the wall (Inbouw) works asfollows:1. Inside the concrete walls, pipes installed first before

concrete casted, used pipe threads (chroefbuis) and

should not be painted by meni. On the plasteredwalls, the holes and channels for planting a pipe andso on.

2. Created and prepared after walls are finished. Usedpipe by selorok connection (schuifbuizen) andpainted by meni before plastered

12.Installation of the contact box should be equipped witha safety contact, except if there is additional insulationto prevent safety hazards voltage;


28/32


13. Pull connector the pivot (strekleiding) above the ceiling or

plafond, the cable network is a transmission-transmission which

pulled tight with the pivot (steupunt) using a roller insulator, with

the following provisions:

* The maximum cable distance between 3 cm;

* The distance between the insolator as the most distant fulcrum

(maximum) 1 meter;

If the cable cross-section size of 4 mm or more is greater

insulation (clop-insulator) with a maximum distance of 6 meters;

Branching at strekleiding should be made free of traction.

Cable for minimum light-sectional area 0.5 mm2;


29/32


14.Fitting Edison should only be used for lamps with a

power of 300 watts, and above 300 watts to 1500

watts used Galihath fittings.15.Each installation must be equipped with the house

fuse and main switch;

16.Each box of contacts (stop contak) only allowed forsingle channel or contact toothpicks.
