Guides
Practical guides based on NEN 1010 and NEN 3140, translated into 5 languages.
NEN 1010 — Low-voltage installations
NEN 1010 protection principles: electric shock, thermal, and overcurrent. Select system (IT/TT/TN) and RCD 30mA.
Learn about protective earthing (PE), PE colors, TN-C-S and TT systems. Important PE rules and standards such as NEN 1010 and residual current devices (RCDs).
AUV: protection against indirect contact in TN systems. Required short-circuit current and disconnection times for fuses, MCBs, and RCDs according to NEN 1010.
RCD guide: 30mA for persons, 100-500mA for fire protection. Installation, testing, and N-conductor rules according to NEN 1010.
NEN 1010 bathrooms: zone 3 is eliminated, 30mA RCD is mandatory, and supplementary earthing is required. Read the requirements for safe electrical installations.
NEN 1010 section 712: requirements for photovoltaic systems. DC isolator, inverter, and safety.
NEN 1010 §722: requirements for EV charging points. Separate circuit, RCD type B or A with DC detection. Mode 2, 3 and 4.
NEN 1010 for horticulture: IP55/IP67, RCD type F/B, residual current devices, and equipotential bonding in greenhouses.
NEN 3140 — Safe electrical work
NEN 3140 VP exam: 60 questions, 70% pass rate. Prepare for the 5 golden rules and RCD types.
Risk inventory and assessment for electrical equipment — how do you determine the inspection frequency in accordance with NEN 3140 §5?
NEN 3140 inspection: visual, measuring and documenting. Mandatory for employers. IV is responsible.
A step-by-step guide to safely de-energizing electrical systems using Lockout/Tagout (LOTO) procedures to prevent unexpected energization and ensure worker safety.
