I recently failed an inspection because the existing exit/emergency lights were on a dedicated circuit with a sp breaker lock. I was told that circuit needed to be tied in with a breaker that controls a row of lights in the vicinity of 2 emergency lights.(There are other e/e's throughout the building....a liquor store) Customer turns the fixtures on and off by the breakers. Just wondering if Art#700.12(F):exception would apply? Light fixtures and e/e's originate from the same panelboard. There are more than 3 rows of lights. My remedy was to tie e/e circuit in with a row of lights to be left on 24/7.
Any thoughts?
Thanks!

OK, a plain english explanation....

One open large area/room/store/office, etc.
IF three (3) or more lighting circuits in that 'room', you are allowed to have a 'dedicated' exit/em circ w/cb lock.

IF NOT, the exit/em lighting has to be circuited (connected) to the local lighting circuit, before any switch.

You also mentioned 'existing'; did you touch, modify, relocate, or not touch it?
Usually, a retail store falls under the 'more than three (3) circuits', and has a dedicated exit/em circuit with the 'nite lites'. The number of 'rows' is not really relevant, it's the # of lighting circuits.

What part of NJ are you in ?? And what Article was cited? and by who, Elec, Fire or Bldg?

Hi and thanks for your reply.
Just added 1 exit/em with a dual remote head outside, from existing exit/em dedicated circuit. Easily more than 10 lighting circuits from panel. (1 circuit per row)

SJ.... Art 700 .....Elect

Best solution...call and speak to the elec inspector, explain that there are more than 3 circuits, the e/e is dedicated, and there is a breaker lock. Conformance with Art 700 IMHO, from your explanation.
