LIVING ROOM CALCULATION
Led tubelight of 40 watts
Spot light = 4 nos
Ceiling fan = 2 nos
Tv = 1 nos
Utility socket = 3 nos .
WATTS CALCULATION FOR LIVING ROOM
1 SOCKET OF 6 AMPS
Amps To Watts
Watts = Amps x Voltage (220 India)
Watts = 6 x 220 = 1320 Watts
2 SOCKETS OF 15 AMPS
Watts = Amps x Voltage (220 India)
Watts = 15 x 220 = 3300
Watts = 2 Nos of sockets x 1320 = 6600 Watts
AMPS CALCULATION FOR LIVING ROOM
As per the note, this building is fully connected with the three-phase system

DeleteHow much Total length of cable sir
ReplyDeleteCan we combine LL and PL mcb
ReplyDeleteWHILE CALCULATING AMPS = WATT X DF/VOLT(1.732). WHAT/WHY THIS 1.732?
ReplyDeleteIn a 3-phase system the voltage between any two phases is 3 times higher than the voltage of an individual phase by a factor of 1.73 (square root of 3 to be exact). ... A 220V system with three 220V phases has a 220 * 1.73 = 380V cross-phase voltage.
DeleteYour calculation is Confused. You have used 3-Phase formula to get the total current (Amps) on Single phase.
ReplyDeletegreat idea but really confusing.
