Project Requirements:
A hospital has a reception and waiting area, two male and female wards, one
operating room, one emergency room, and three restrooms. A telephone is
available at the Reception desk (PSTN). The operating room must contain a
spotlight outlet. Install an exhaust fan in the restrooms. The hospital should
have smoke detectors and fire alarms installed. Except for the restrooms, each
of the rooms above has a sub-distribution board, while the main distribution
board for the department is located at the entrance.

Number of Light Calculation
1. Reception & Waiting Area:
Total lumens required = 21.5×15×150×0.093/0.8×0.6 = 9372.656 lumen
Required wattage = 9372.656/120 = 78.1 watt
Here, 4 LED lights of 15 watt and 2 LED lights of 10 watt to be used to comply with the requirements.
So, power to be supplied = (15×4)+(10×2) watt = 70 watt
2. Male Ward:
Total lumens required = 37.5×20.5×150×0.093/0.8×0.6 = 22341.79688 lumen
Here, 4 LED lights of 32 watt and 2 LED lights of 30 watt to be used to comply with the requirements.

3. Restroom 1:
Total lumens required = 5×10×100×0.093/0.8×0.6 = 968.75 lumen

So, power to be supplied = 8 watt
4. Female Ward:
Total lumens required = 24×38×150×0.093/0.8×0.6 = 26505 lumen
Required wattage = 26505/120 = 220.875 watt
Here, 9 LED lights of 25 watt to be used to comply with the requirements.
So, power to be supplied = 25×9 watt = 225 watt

Wire Size Calculation
Reception and Waiting Area
Total Load Of Room=568 W
Distance from MDB to SDB=18.0208’
After adding 15% Additional Load=653.2
Current=2.969 A
Cable Size=(1/1.40)10 A
Current Capacity at 45°C=0.91×10=9.1
Voltage drop for 100 ft= 14 V
Length of cable= 18.0208
So voltage drop=0.749 V
Therefore cable size should be=(1/1.40)10 A

LED Light-1
Total load of light=15 W
Distance from sub distribution board=9.25’
Total load after adding 15% additional load=17.25 W
Total Current=0.078 A
Cable size=(1/1.40)10 A
Current capacity at 45°c=0.91×10=9.1
Voltage drop for 100 feet for this cable=14 V
Here,length of the cable=9.25’
So voltage drop=(14×9.25×0.078)/(100×9.1)=0.0111 V×
Therefore cable size should be=(1/1.4) 10 A
LED Light-2
Distance from sub distribution board=13’
Here,length of the cable=13
So voltage drop=(14×13×0.078)/(100×9.1)=0.0156 V
LED Light-3
Here,length of the cable=16.75
So voltage drop=(14×16.75×0.078)/(100×9.1)=0.0201 V
LED Light-4
So voltage drop=(14×19.5833×0.078)/(100×9.1)=0.02349 V

LED Light-5
Cable size=(1/1.40) 10 A
Current capacity at 45°c= 0.91×10=9.1
Here,length of the cable=13’
So voltage drop=(14×13×0.0522)/(100×9.1)=0.01044 V
Therefore cable size should be (1/1.40) 10 A
LED Light-6
So voltage drop=(14×30.33×0.0522)/(100×9.1)=0.024 V
Ceiling Fan-1
Total load of fan=75 W
Hence cable size is =35.35’
So voltage drop=(14×35.25×0.392)/(100×9.1)=0.213 V
Ceiling Fan-2
Hence cable size is = 38.83’
So voltage drop=(14×38.83×0.392)/(100×9.1)=0.23 V

Ceiling Fan-3
So voltage drop=(14×30.33×0.0522)/(100×9.1)= 0.18V
Ceiling Fan-4
So voltage drop=(14×28.9167×0.0522)/(100×9.1)=0.171 V
3 Pin Plug Point
Total load of 3 pin plug=200 W
Total load after adding 15% additional load=230 W
Hence cable size is =35’
So voltage drop=(14×35×01.045)/(100×9.1)=0.5626 V
2 Pin Plug Point
So voltage drop=(14×20.5×0.2195)/(100×9.1)=0.069 V

Telephone
Total load of telephone=5 W
So voltage drop=(14×45×0.028)/(100×9.1)=0.01938 V
Fire Alarm
Total load of fire alarm=1 W
Total Current=0.0.00522727 A
So voltage drop=(14×13×0.00522727)/(100×9.1)=0.001045 V
Male Ward
Total Load Of Room=12791
Distance from MDB to SDB=42.5625’

Female Ward
Total Load Of Room = 13128 W
After adding 15% Additional Load = 15097.2W
Total Current = 68.6236 A
Cable size = (7/3.0) 91 A
Current capacity at 45⁰ C = 0.91×91 = 82.81 A
Voltage drop for 100 ft for this cable = 3.5 V
Here, the length of cable = 51.541’
So, voltage drop= [(3.5×51.541×68.6236)÷(100×91)] = 1.36 V < 5.5 V
Therefore, size of the cable should be (7/3.30) 91 A
LED Light 1
Total load of light = 25 W
Distance from sub distribution board = 11.75’
Total load of light after adding 15% additional load = 28.75 W
Cable size = (1/1.40) 10 A
Voltage drop for 100 ft for this cable = 14 V
So, voltage drop= [(14×11.75×0.1306)÷(100×10)]= 0.021 V < 5.5 V
Therefore, cable size should be= (1/1.40) 10 A
LED Light 2
