Case Studies
Case Study 1 – Facility Maintenance Contractor (Georgia, USA)
A building safety services firm used GAO Tek earth leakage testers supplied by ElectricalTestTek to audit workplace circuits. The enhanced testing process reduced false trips by 25% and improved overall safety documentation.
Case Study 2 – Industrial Manufacturer Compliance Checks (Pennsylvania, USA)
A production plant integrated our testers into periodic safety audits. As a result, undetected leakage faults were identified early, reducing unplanned shutdowns and improving regulatory compliance.
Case Study 3 – Healthcare Facility Diagnostics (Ontario, Canada)
A Canadian hospital adopted ElectricalTestTek’s GAO Tek earth leakage testers during emergency panel commissioning. This improved fault detection accuracy and ensured system readiness for critical power continuity.
