A » To identify a hot wire, use a non-contact voltage tester or multimeter. Ensure the circuit is live, then place the tester near each wire; a hot wire will trigger a voltage indication. Typically, hot wires are black or red, but always verify with a tester, as colors may vary. Exercise caution and consider consulting a licensed electrician if unsure about handling electrical systems.
