Does Ontario Electrical Code edition / ESA state any ruling for light fixtures fed with normal power source and emergency power source (inboard / outboard lamps, both same voltage-347) to have special requirements ie: barriers or labels?
Thanks, Red

14-414 Connection to different circuits
(1) Where electrical equipment is supplied by two or more different transformers or other different sources of
voltage, then
(b) each supply circuit shall be provided with a disconnecting means integral with or adjacent to the
equipment, and the disconnecting means shall be grouped together.

(3) Where multiple disconnecting means as in Subrule (1)(b) are provided, suitable warning signs shall be
placed on or adjacent to each disconnecting means so that all of the disconnecting means must be opened
to ensure complete de-energization of the equipment.

I would think to be in compliance, you would need to place labels on the switches, but I have never seen anything like that.
Best to call ESA and ask them

Did this come from the factory like this. I believe I have seen lights where it said there may be more then one source of power and to disconnect all sources.

Wcord,
Thank you for your reply, it has been most helpful.

Further investigation reveals Electrical Contractor is responsible for any/all labels clearly advising power from two sources.

347v disconnect device to be manufacture installed per CSA serves as safety disconnect

Barriers are only required if two separate power sources are different voltages.
