Two 250A LT panels in the F block receive electrical power from Generator 1 near the swimming pool. The right panel divides its 240sqmm cable into 7 circuits serving the basement through 2 floors, while the left panel divides its 185sqmm cable into 6 circuits serving the basement through 1 floor. The LT lines then run to bus bars on each floor and are divided into circuits protected by MCBs to supply different parts of each floor, including separate circuits for each classroom.

2. FROM WHERE?
• Only LT lines comes to f block along
with solar connections.(we are not
considering)
• The line comes from generator 1 (dc
set 1) near swimming pool.

3. 2 LT PANELS ARE THERE
