Start with Webster's Dictionary.
A system drawing is a drawing of a whole.
A detail drawing is a specific component of a whole.
A system drawing can be a detail drawing.
A detail drawing can not be a system drawing.

Re: system drawings
"System drawings" is too general of a term to apply to anything specific. What context is the term used?

Re: system drawings
Sounds like an exam question. I have seen many that did not make any sense.

Re: system drawings
I do work for a facility that requires "system drawings" for all separate operations in one area. For example, I have diagrams and layouts of the lighting, one for general purpose circuits, one for each specialized equipment circuits, and so on.
This is a very large facility that requires such separation to avoid confusion and misidentification of circuits.
In regards to a single occupancy or a dwelling, I would consider the system drawings as being the wiring diagram updated to as built.
See 215.5 for NEC related requirements.

Re: system drawings
Yes, it was a question on an exam. But it was not multiple choice. It was an exam that was part of a job application. One of many I have come across...seems to be a trend. And I have no problem with that. It is fine with me.
The question was: What is contained in the "System Drawings"?
But after several weeks of searching for the answer I am flustered.

Re: system drawings
I had a freind (who recently died) came from electronics into machine control in a factory. He was shown a machine interlock drawing at the onterview (10 or 15 door switches in a line, -||--||--||-) and was asked about the circuit. Reply "You'll never get a signal thru all those caps!"

Re: system drawings
kholland may be on to something:
"It seems too broad of a question. You have electrical systems, fire alarm systems, plumbing systems, roof systems, etc..."
Low-voltage systems like voice/data/video, cctv, catv, home theater, etc., often appear in a subset of electrical drawings sometimes labelled "special systems" or something like that. the idea is, i suppose, to distinguish this stuff from typical lighting, hvac, etc. plans, since they are often bid and installed by a different contractor.
