Answer / shantanu

RCCB means residual current circuit breaker and MCB means
miniature circuit breaker.The difference between RCCB and
MCb is : RCCB Protects against residual leakage current.The
ratings are mentioed as 30mA,100 mA etc.But MCB only
protects against short circuit.

Answer / bhigesh

residual cercuit breaker and miniture circuit breaker

Answer / satish

RCCB are also called as ELCB Earth Leakage Circuit Breakers
and they are also available in 20mA, 100mA.

I have a question, I visit 01 site and face a problem, there is 2.5 ton Air Con working, when air con compressor is running at that time rectifier voltages are increasing upto 290-295 v and rectifier is giving main high alarm (rectifier is APC single phase, before starting compressor rectifier voltages was 230v. when air con is going off rectifier voltages are decreasing smoothly at its actual voltages 230v. Load on Genset phases is this: Red-13.5 amp AC (Air Con load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp AC (telecom system load), Genset phase to phase and neutral to phase voltages are also ok. These are 10 sites having same system and same rectifier APC brand at every site 02 genset are working but the problem is same at all these 10 sites. What will be the reason behind???
