II-966933-2020 (#16355)

Location: Nelson

Regulated industry sector: Electrical - Low voltage electrical system (30V to 750V)

Incident overview

A high impedance arcing condition was caused by a loose conductor termination. Over time, the arcing condition resulted in an elevated temperature at the termination point, which ultimately exceeded the temperature rating of the conductor insulation and resulted in an electrical fire. No one was injured.
