Incident Investigation

Contactor Was Damaged From Overheating

January 2, 2022

Electrical

Reference Number:

II-1450906-2022 (#30115)



Location: Cobble Hill

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

Incident Overview

A dust collector imported from Europe was connected to a 208 Volt three-phase branch circuit. The equipment was designed to operate using 400 Volt three-phase power. The contactor and wiring were carrying almost twice the load current, resulting in overheating conditions as they were undersized for the 208 Volt source.
