Hi,
I am new in the MEP field and I have a question about lighting. I was told that the tick marks in a lighting plan represent the number of conductors. How do I know when to show the tick marks and when not to?
 
Personally I don't like the tick marks as there are other (IMO better) ways to identify what the circuits are on the drawing. We usually have a dashed box around each area that contains a single lighting circuit with a note as to the circuit designation. If you had a simple two wire circuit you could just put two tick marks on all of the connections.

Around here it was a half tick mark for a neutral and full marks for ungrounded conductors. At least is was a long time ago, has been a very long time since I did any commercial work from prints.
