Identifying schematic symbols in a circuit breaker diagram

[MrSen]

Help a newbie with schematic symbols ^_^"

Hey all!

Im kinda stucked here with these symbols. Does anyone have any idea?

1. I think its a terminal, but I am not that sure, since it is connected to a circuit-breaker (which is connected to a transformator)

2. Just to clarify, is 250A the current rating of the circuit breaker?

3. What does this "M" stand for?

4. What does this "C" stand for?

5. What does this "12 of" stand for?

6. "EG" ?

Thanks a lot for all the help! ;)

Welcome to PF.

These symbols appear to be those used in "one-line/single-line diagrams".

M = motor
C = clock?
EG = emergency generator?

I would want to see the full schematic to know for sure.

I haven't seen a lot of these, but I'm not that experienced either. The * i have seen as some type of off-page connectors before though.
