Is white wire with grey stripes positive or negative wire?
I want to re-wire an AC to DC power adapter for an ONT (Optical Network Terminal - AKA Fibre Box mounted on a wall) and replace the adapter with a standard DC plug. This is because I want to connect it to a UPS (uninterrupted Power Supply).
How do I tell which one of the two wires is the live or positive wire in this picture?
I am from South Africa, if that is at all applicable. This is the cable connected to an ONT.
