2 General Description of Electrical Installation Planning
In planning electrical installations there are provisions in the form of regulations which are mentioned as follows:

Electricity system 2.3.1. Share Link Panel
Connection Equipment (PHB) is an equipment to share electric power or control and protect circuits and electricity beneficiaries including circuit breaker switches, low voltage switchboards and so on.Types of Connecting Equipment According to their needs, PHB is divided into 2 types, namely: 1).Main PHB is a PHB that receives the flow of electric power and sources through the consumer's main switch and distributes the electricity to all user devices in the consumer's installation.
2).PHB Sub-Installation or PHB Branch is PHB from an installation to supply electricity to one consumer and the installation is part of an installation that supplies one or more consumers.

Sender/Cable
The conductor/electrical cable to be used must meet the requirements such as being able to withstand electrical, mechanical, thermal and chemical resistance.In addition, it can also deliver maximum current and must have the smallest possible losses.Here are some types of conductors/cables that are commonly used in electrical installations [9], [10]: a. NYA b.NYM c. NYY d.NYCY e. NYAF

Light
The main component in lighting which is the last point in a lighting installation, serves as a source of light in rooms that need adequate lighting.There are many types of lamps that are often installed in homes, industrial buildings, and other buildings.The following types of lamps are often installed (popular) for lighting installations [9], [10].a. Incandescent lamps b.TL Lamp (Tubular Lamp) c. Lampu LED (Light) d.LED Downlight

Determine the Number of Lights
The technique of determining the number of lights is by paying attention to the appearance of the color which is described by the color temperature and the effect of the color on the object being illuminated which is explained by the color index number and also the efficiency of the room [9], [10], [11].

Space Index
The room index or form index expresses the comparison between the main dimensions of a square-shaped room, which is formulated by the following equation: Where : p = Length of room (m) l = Width of the room (m) h = Height of the light source to the work area (m)

Space Efficiency
Room efficiency can be determined with the lighting efficiency table by finding the right room index value (k).If the value (k) is not found correctly in the existing table of lighting systems, efficiency and depreciation, then the room efficiency is obtained by the interpolation method, namel [10]: The formula for calculating room efficiency is: Where : ɳ1 = utility factor lower limit ɳ2 = upper limit utility factor k = Index of the room to be determined k1 = Lower limit room index k2 = Upper limit room index

Light
After determining some of the parameters above, the following equation is used to find the number of lights:

Power Requirements
To calculate the power requirement from the number of lamps obtained is as follows:

AC Capacity Calculation (Air Conditioner)
Air Conditioner (AC) or air conditioning device is a modification of the development of engine cooling technology.This tool is used to provide cool air and provide the moisture needed for the body.To be able to produce air with the desired conditions, the equipment installed must have a capacity that matches the cooling load that the room has.For this reason, a survey is needed and determines the amount of cooling load [9].The formula used to calculate the power requirements of the Air Conditioner is:

Determine the Cross-sectional Area
The nominal load current (In) passing through a conductor can be calculated using the following formula: For single phase alternating current: For three-phase alternating current: Where :  ∅ = Power of one phase (watts)  3∅ = Three-phase power (watts)   = Tegangan phase-phase (volt)   = phase-neutral voltage (volts)   = Power factor Current-carrying strength (KHA) in the final circuit is determined by the formula: Calculating the final circuit overcurrent protection rating is determined by the formula: Where : KHA = Strong Current Delivery (ampere)   = Protection rating (amperes) In = Nominal load current (amperes)

Calculation of Voltage Drop
Voltage drop is the amount of voltage lost in a conductor.The voltage drop on electric power lines is generally directly proportional to the length of the line and the load and inversely proportional to the crosssectional area of the conductor [9], [10], [11].
In this discussion what is meant by voltage drop (∆) is the difference between the sending voltage (Vs) and the receiving voltage (Vr), then the voltage drop can be defined as: The relative voltage drop is called the voltage regulation VR (Voltage Regulation) and is expressed by the formula: Where : Vs = voltage at the sending end Vr = voltage at the receiving end In simplifying the calculation, it is assumed that the loads are balanced phase loads and the power factor is between 0.53 to 0.85.The voltage drop can be calculated based on the relationship approach formula as follows [12]: ∆ =  ( . +  .) (12) Where :
