Working dead (de-energised)
NIPT (Niet onder spanning werken In de Praktijk)
Also known as: nipt, niet-onder-spanning, dood-werk, dead-work, working-dead, spanning-vrij-werken
Standard work method under NEN 3140 — performing tasks after the installation is fully de-energized and verified. Working under voltage is allowed only in rare cases.
Practical example
NIPT (Not Working Under Voltage in Practice): A fault in a distribution board is fixed only after the relevant circuit is switched off and confirmed dead, instead of working live.
Common mistake
NIPT (Not Under Voltage in Practice) Common mistake: Working under voltage 'quickly' under time pressure without following the exception procedure (risk analysis, additional PPE) — this is no longer NIPT but unauthorized live working.
