can you give main difference between ELCB And RCCB?
Answer Posted / suresh g
elcb means earth leakage circuit breaker which operates when
there is a leakage of current from phase to earth.
Rccb means residual current circuit breaker which operates
when there is a difference in current between any two
phases.This differential current is called resdual current.

what are the application of over current relay?
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.
