This is a 8 wire 0.5mm2 cable (insulator is PVC), there's 17 strings of copper in each wire.
I couldn't find the current capacity of this specific wire on their website but their 1.5mm2 x 8 cables are capable of handling 27A when distance is about 10 meter (reduces to 5A when distance is 150 meter).
I'm going to pass a maximum of 7-8A through two of this wires (other wires gonna carry about 1A) and the distance is about 1.5-2 meter.
Can this wire handle 8 amperes of current?
wires current: 1. LEDs 12V 30W 2.5A 2. Waterpump 220V 40W ~200mA 3. Airpump 220V 20W ~100mA 4. Heater 220V 300W 1.5A 5. MCU* 5V ---- 500mA *there's some relays connected to MCU that's why it's using 500mA. and two wires gonna be 220V INPUT which gonna carry ~5A in total.
