I particularly like the idea of switching the earth through the contactor. Classy
are plastic tie wraps meant to be used on cable trays now? ive heard at collage that they are not meant to be used anymore,simply for fire fighters safety in the event of a fire.Cables strewn everywhere cos the tie wraps have melted cant be good
on my AM2 i used ties but they wanted the pyrofil emergency circuit cable clipped and bolted to the tray, dont know if this could apply in the real world, surely in a fire wires are going to melt regardless of how they and fixed? as long as the emergency circuits are held in place untill building is evacuated.
cables usch as pyro (Mineral insualted copper clad to ba accurate), or FP200, must be fixed in a way that they remain intact during a fire. I doubt that you would bolt to tray on a normal job, stainless ties would be more efficient.
