Hi all
I have built an automation circuit where 5 relays will be controlled using Bluetooth & IR.Each relay will control a max load of 100w.The Voltage to be operated on is 220v AC.The switching will be done on the Live side.(All neutral common for the loads).So to do this,I have connected all the COM pins of the relay's & then connected to 220v Live.The NO pin is connected to each load.So,the Max power on the track connecting all the COM's,will be 5x100w=500w(If all the loads are on).I have used 100 mil trace width for this track.I used this calculator to calculate the pcb width.Is this trace width ok to handle 500w in 220v AC?I am attaching PCB pic for your ref.The track is marked with red.The tracks that connects the NO pin to load is 66 mil.Will that be adequate to handle 100w load in 220v?Please give your valuable feedback....I have already built 10 pcbs
