Definition of Incomer

[GOTWW]

I hear it, and have used it. Do not see it in the power books. What is the cononotation, just an upstream feed to other stuff? (protected by it's own means.)

 

[CJFlatters]

Not sure what you are asking, or your application.

By definition, an incomer is just that, an power feed to a switchboard, MCC, or simply an isolator (oops - slapped wrists, I meant to say disconnector or switch-disconnector) on a distribution board

It may typically be an ACB, MCCB, possibly having overcurrent and / or earth-fault protection or possibly just a manual switch disconnector (definition as IEC 60947-2)
