Hi all, We are manufacturing heating equipment for industrial use. Our equipment is one part in an "in line" setup of machines. We are required, by one company we deliver to, to provide a wire for equalizing the earth potential between our control cabinet and the frame of the main machine.
The heater is about 50kW at 400V. The required wire is 35 square millimeters copper wire. The equiment in this case is for the European market. I think what they are afraid of is that current will flow in the shields in the control cables between the different parts of the setup, creating problems. Are there any standards that require this? Is this "standard procedure"? Best regards Janne Engstrom --------- This message is coming from the emc-pstc discussion list.
