1,000 views

L2 is not always neutral. In electrical systems, L2 usually refers to one of the hot lines in a split-phase power system. The neutral line is a separate conductor designed to carry the return current and balance the voltage.

FAQs & Answers

  1. What does L2 mean in electrical wiring? L2 is one of the hot lines in a split-phase electrical system, carrying live current, unlike the neutral line which returns current.
  2. Is L2 the same as neutral? No, L2 is a hot conductor in a split-phase system, while the neutral is a separate conductor meant to balance voltage and carry return current.
  3. Why is the neutral line important in split-phase power? The neutral line provides a return path for current and helps maintain voltage stability across the system.
