When doing an EIC for an additional circuit (which only covers that circuit), does the 'main switch/switch-fuse/circuit-breaker/RCD' section refer to:
a) the MCB you're adding for the new circuit
b) the existing main switch (whatever it is) for that board
c) [if the DB the circuit is added to is a sub main fed from another DB] the breaker supplying the sub main
And, in the case of (c) would the 'supply protective device' under 'supply characteristics and earthing arrangements' still be the DNO's main fuse, or would it become the breaker supplying the sub main?

- TL;DR
- What does 'main switch/switch-fuse/circuit-breaker/RCD' on an EIC refer to?
