14-414 Connection to different circuits
(1) Where electrical equipment is supplied by two or more different transformers or other different sources of
(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
