@okeganew: Can a 4-pole changeover work for single phase? Yes,but only with correct wiring ⚡ Don’t try this if you don’t understand it. This diagram shows how a 4-pole manual changeover is used for Phase (P) and Neutral (N) only. 🔹 Top = Grid (NEPA) 🔹 Bottom = Generator/Inverter 🔹 Link terminal = Load (your house) ✔️ Two poles carry Phase & Neutral to the load ✔️ Switch UP → Grid supplies ✔️ Switch DOWN → Generator/Inverter supplies ✔️ Both sources are never connected together (safe switching) 💡 The extra poles can be unused or kept for future upgrade. ⚠️ Neutral is also switched for proper isolation #electrician #electricaltutorial #tiktokelectrician #housewiring #fyppppppppppppppppppppppp
