Rod, strip, plate, ring, foundation electrodes; TT: RA × Ia ≤ 50 V.
Table 54.2: S ≤ 16 → S; 16 < S ≤ 35 → 16 mm²; S > 35 → S/2. Separate PE: 2.5 mm² protected / 4 mm² unprotected.
Main bonding in every building; supplementary in bathrooms/pools.
Copper ≥ 10 mm² / aluminium ≥ 16 mm²; never broken; not through RCDs; PEN split — PE first.
Automatic single-line diagrams, PUE/GOST/IEC calculations, specification and PDF — from one model.
