ECG’s Comprehensive Underground School equips utility workers with the skills necessary to safely operate, maintain, and repair an underground electrical system. Today’s congested underground environments require utility workers to be properly trained to safely work on critical infrastructure.

ECG’s 3 ½ day program will cover the core competencies of underground primary electrical systems to ensure that students can perform three-phase switching, protective grounding and isolation, pad mount transformer installations, and the proper make-up of 200-amp and 600-amp components.

This comprehensive program will outfit utility workers with the skills needed to safeguard underground infrastructure for years to come.
