What is difference between incomer & outgoing type Vaccum
Circuit Breaker?

Answer Posted / vijaykumar

there won't be any differenece b/w VCB's used in the
incomer or outgoing feeder provided the current ratings of
both are same.The protection and control wiring differs b/w
them as incomer needs only U/V,O/V,O/C,E/F protections but
the outgoing contains differnet protections depending upon
the load requirements.
