I am building a lab power supply that is going deliver 0-6 A at 0-35 V, maybe 40 V. The power supply is almost ready to go in use.
On the power supply there are nice big banana connectors that can handle easily 10 A.
To wire circuits and other devices I need a cable with banana connectors. I started thinking if I am able to make it myself.
So here is my idea:
I order nice banana male plugs and a nice thick black and red silicon cable.
My problem is: which size do I need for around 6 A? I have looked at wire current tables, they suggest a cable size of 13AWG for 7.4 amps power transmission, but the same cable can handle 35 A for chassis wiring.
They explain that chassis wiring are lose runs of cables surrounded by air. Another calculator says I only need 18AWG.
Can somebody help me with a suggestion on which cables in need to buy. To clarify the specs that the cable needs to handle are:
- 0-40 V
- 0-6 A
- 80 cm in length
