00:00.000 --> 00:05.645
The TNC scheme: neutral to earth, masses to neutral and common

00:05.645 --> 00:16.632
I start by connecting the earth to the neutral

00:16.632 --> 00:26.505
No differential in TNC, I connect neutral and phase

00:26.505 --> 00:39.245
Neutral and mass are common, I save a wire returning to the source

00:39.245 --> 00:51.135
Low ignition: single voltage. I realize a phase-to-ground short circuit

00:51.135 --> 01:07.747
Short-circuit instantaneous tripping (cct) due to the ground-to-neutral connection

01:07.747 --> 01:11.339
Fortunately we work in 24 Volts!
