Hello, I'm having trouble deciphering a few symbols:
1) is this a switchboard?
2) I have no idea what it could be
3) what does the number "2" in the socket designation mean?
4) what does the extra "arc" in the socket designation mean?
5) a question of confirmation is this a box designation?
6) what does the crossed out line in the lighting outlet designation mean?
Thanks in advance.
