I'm modelling a power system, and encountered a few symbols I have never seen before in a single line diagram.

I believe the first one is a switch with three possible position. Closed, open and grounded. Is this correct, or am I wrong?

I haven't got a clue what the second symbol indicates? It must be some sort of feeder, but what is the purpose of the brackets? It doesn't appear in the tables for either IEC or ANSI.

Has anyone seen this symbol before?
