Wire size supply infeeds
Slicc posted a topic in Control Panel BuildingHello, I want to ask for a second opinion regarding sizing infeed wires and cables. Take this case for example: 5G16 incoming supply cable (400VAC 3PH+N) to a panel which goes through a MCB and then to a potential distribution block. From there on i can feed various supplies: 1 off 30A Inverter (4mm wire) 1 off 15A Motor (1.5mm wire) 1 off 24VDC PS (2.2A) (1mm wire) The wires from the potential distribution block to the MCP (inverter / motor) an MCCB ( PS) do they all have to be the same size as the highest consumer? This case inverter so 4mm? Thank you.
