I am designing a simple switch controlled relay board. On board I have two 5Vdc 10Amp Sugar Cube Relays which will receive 230Vac from Terminal block connector and will be controlled with 5Vdc input via SPST Switch.
Operating current : 10 Amps
Terminal Block : Pitch 2.54mm
According to trace width calculation trace width required for 10 Amps is 4.2mm
PCB Copper Thickness : 60 micron
Will 230Vac LINE trace from terminal block (Pin 1) to both relays(via Relay K1) needs to be 4.2mm or 8.4mm(i.e. double) or different as single trace is coming from terminal block and going to both relays?
