What it is

  • Vertical electrodes 2.5-3 m + horizontal strip;
  • Connected to the GZSh in the panel;
  • Resistance: TN ≤ 4 Ω, TT ≤ 30 Ω with RCD.

Measurement

3-pole method with a ground tester: the current electrode and the potential electrode are driven in; the resistance is measured. Not a multimeter.

FAQ

Why measure?
The RCD/breaker operation depends on the loop: a bad loop — the protection does not work on time.
How often?
After installation and every 5-10 years; after construction works near the loop.
