Yes, both L1 and L2 can be 'hot' wires in electrical wiring, typically carrying live current. This usually applies to systems with 240V where each hot wire contributes to the total voltage. Ensure to turn off the power supply before handling any electrical work to avoid hazards.

FAQs & Answers

  1. What does it mean for a wire to be 'hot' in electrical wiring? A 'hot' wire carries live electrical current from the power source to the load, and contact with it can result in electric shock.
  2. Why are both L1 and L2 considered hot wires in a 240V system? In a 240V electrical system, L1 and L2 are each live wires supplying voltage, and together they provide the total voltage by being out of phase.
  3. How can I safely handle L1 and L2 wires during electrical work? Always turn off the main power supply and verify with a voltage tester before handling any wires to avoid electrical hazards.
