Hi,
I am designing an electrical panel for my fourth year electrical engineering project and had a afew questions about the electrical code in Canada.
The main disconnect that I have has a single set of contacts, which means that the input AC neutral is not disconnected. Is this a violation of the Safety Code? I am still fusing both the Hot and Neutral with separate fuses. Is it still a violation?
I have hardwired the power on and E-stops with hardwire safety (contactors, relays) and am using software safety as a backup. What level of safety does this correspond to(Level 1,2,3)?
At last, I want to display the sequence of buttons the user has to press to make the machine operational bu using Allen Bradley Indicator Push Buttons by showing flashing lights for the button that has to be pressed. This means that the PLC has to be powered as soon as the Main disconnect has been turned on and the Power On light, which is AC will be flashed as soon as the main disconnect is turned on but the user has not hit the switch to turn the power to drives, servos etc on. Is this a violation of the electical code?
Thanks
