[[ CORRECTION: L-N should be N-G or N-E. My mistake. ]]

I live on the ground floor of an apartment building in India. Standard Indian wall voltage is 220V AC. I'm about 5 meters from the circuit breaker box (CBB) down the hall. This CBB only handles the ground floor. Next to the CBB is another electrical box that (I think) is a distribution panel (I'm not an electrician so I'm not sure). If needed I can take pics of the boxes and post them.

When I plug my grounded socket tester in to my grounded wall receptacle, I get about 4.3V Line-Neutral. (My socket tester has a nice LED screen showing all the details.) The socket tester says the connections are correct.

I have an old heavy VGuard 500VA voltage stabilizer (VS) with a ground pin. So I plug the VS into the wall and my socket tester into the VS. At the VS output the socket tester reads about 6V Line-Neutral.

Do these L-N voltages seem safe? Or are the L-N voltages high?

What other details you need?

  • Pictures of everything involved will definitely help.

  • Maybe some details about the socket tester. A plain voltage meter/tester will read full voltage between L-N and L-G(220v) if things are right. Your tester might be reading leakage or something.

  • You should be seeing L-N (and L-G) voltages more like 220-230V. Is the outlet controlled by a switch that’s off?

Are you sure you're reading that right? You should be getting about 220V Line to Neutral, about 220V Line to Ground, and something close to 0V Neutral to Ground.

I could believe 4.3V Neutral to Ground. It's not ideal, but not actually dangerous.

  • Thanks. This is helpful and gives me good context.
