On a 10 KVA UPS we have to provide a DC MCB for Battery bank
of 16 nos (12 V 65 AH).
What Shall be the current rating of DC MCB ?
Answer Posted / asif.k64@hotmail.com
UPS is 10 KVA, and battery is 65AH
Hence if it is a 1 phase UPS
KVA = V*A
10000 = 240*A
A= 10000/240
A = 42 A full load
Approximately a 63 A MCB would be required

As we use capacitor bank in 3ph ckt to improve PF, can we use capacitor in single ph domestric use, in house we have Fan,Mixer,electric cooker,iron,tube choke they also lag the system,because it is inductive load. if it is possible to improve PF of single ph system-- if yes- type of capacitor to be used,connection diagram, working in detail. if no-- list it.
