how much amp MCB is required for 1/2 kva power back up?
Answers were Sorted based on User's Feedback
Answer / shantanu
Look 1KVA = 1000VA
Therefore 1/2 Kva = 500va
For a single phase current
500/230=2.174
So the MCB you can put here is a 2.5AMP as it will not be possible to get a exact 2.174amp MCB
Hope this solves your query.

We have two parts in generator, electrical & mechanical. how it works?
i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
