Electrical Equipment Safety Checklist
An Electrical Equipment Maintenance Checklist helps maintenance and EHS teams turn scheduled work into a clear, repeatable process. Instead of relying on memory, it lays out actionable items across LOTO and absence-of-voltage verification, enclosure condition, labeling and single-line accuracy, conductors and terminations, grounding/bonding, protection devices, motors and starters, VFDs/drives, transformers, UPS/batteries, and thermal inspections. Each item is simple to confirm — from “terminals torqued, no discoloration” to “RCD/GFCI trip time within spec” — so critical details aren’t missed.
For plants and warehouses, this checklist strengthens electrical safety, cuts unplanned downtime, and supports compliance with internal standards and local regulations. Used regularly, it creates a maintenance rhythm where clearances are preserved, wear and hotspots are detected early, and protection settings stay current.
Supervisors gain a clean audit trail. The checklist records who checked what and when, documents defects, and links corrective actions to owners and due dates — invaluable during audits, insurance reviews, and incident investigations.
The template works both as a printable PDF and in the TARGPatrol mobile app. Teams can attach photos, enter measurements, and add comments in real time. Mixed answer types — [Flag], [Number], [Media], [Text] — make it easy to capture conditions, numerical readings (voltage, torque, resistance, temperature, vibration), visual evidence, and context in one place. Regular use improves reliability, speeds maintenance, and keeps your facility inspection-ready.
