Hello,
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.
