Disconnects for Canopy lights and Parking lot

[champion]

Have designed circuits to power lighting on a 40ft square canopy that is 18.5 feet high.
The circuits powering this canopy consist of 20amp 3ph 208v ckts.
Also have designed circuits to power parking lot lighting that consist of various 208v circuits for powering twelve 20 ft high poles.
I have been reading article 600 (sign and outline lighting) and have read 600-6 and am wondering if these lights for this scenario need disconnects.
I did not design for disconnects but have designed the ckts to be switched at the interior ac panel with SWD rated brkrs.
600.6a tells me that for sign and outline lighting, this disconnect has to be in sight of the outline lighting system.
For clarification, would these canopy and parking lot lights be considered outline lighting?
They certainly are not a sign, but outline lighting kinda has me puzzled.
Do I need disconnects located within sight of the parking lot lights and canopy?
It seems if I do need disconnects, per 600.6a I may be able to add a mechanical controller located near the AC panel providing the brkr can be locked in the open position.

Thank you in advance for any input.

Re: Disconnects for Canopy lights and Parking lot

Outline Lighting is defined in Article 100. It doesn't appear that your particular installations meet this definition. I don't believe Article 600 will apply.

Re: Disconnects for Canopy lights and Parking lot

I agree with Bryan, Article 600 should not concern you.

However 225.31 and 225.32 will be an issue for the canopy if it is separate from the building the feed comes from. The light poles are also structures but there is an exception for light poles that allows the disconnect to be located elsewhere. (Exception No. 3 225.32)

225.31 Disconnecting Means.
Means shall be provided for disconnecting all ungrounded conductors that supply or pass through the building or structure.

225.32 Location.
The disconnecting means shall be installed either inside or outside of the building or structure served or where the conductors pass through the building or structure. The disconnecting means shall be at a readily accessible location nearest the point of entrance of the conductors. For the purposes of this section, the requirements in 230.6 shall be permitted to be utilized.

Also 250.32(A) may be an issue at both the poles and the canopy depending on how many circuits are at each location.

250.32 Two or More Buildings or Structures Supplied from a Common Service.

(A) Grounding Electrode. Where two or more buildings or structures are supplied from a common ac service by a feeder(s) or branch circuit(s), the grounding electrode(s) required in Part III of this article at each building or structure shall be connected in the manner specified in 250.32(B) or (C). Where there are no existing grounding electrodes, the grounding electrode(s) required in Part III of this article shall be installed.

Exception: A grounding electrode at separate buildings or structures shall not be required where only one branch circuit supplies the building or structure and the branch circuit includes an equipment grounding conductor for grounding the conductive non?current-carrying parts of all equipment.
