We are working at a site that has a small electric gasoline filling station. The pump/controller requires three circuits (1 for each pump and 1 for the electronics). These circuits are fed from breakers that open the neutral and the feed. Locally, near the pump they wish to add disconnects. Our question is do these disconnects have to open the neutral also? What is the reason behind this. Also there is an emergency stop relay activated by a pushbutton. Does this relay also have to open the neutrals.
