Ok, grand daughter went home, and I was able to get out my code book. I found the in's and out's of the wiring required. And according to my interpretation of the disconnects required, it says in
Article 600-6 ( 99 code), "Each sign and outline lihgting system, or feeder circuit or branch circuit supplying a sign or outline lighting system, shall be controlled by an externally operable switch or circuit breaker that will open all ungrounded conductors". When it says "each", I assume this means that each transformer is considered a different system, therefore requiring a disconnect at each transformer.
If anyone has a different or better interpretation, I would appreciate your response. Thanks a lot, sorry for all the unneccesary questions. It's one of them rush days... Thanks again.. Steve
