Why Data Center Power Distribution Equipment Training Matters
This 12-hour instructor-led course teaches the equipment logic behind that chain: how switchgear, transfer switches, busway, and PDUs are built and how they operate, which UL, IEEE, and NEMA standards govern each device, and how electrical engineers, maintenance technicians, and contractors trace redundancy and standards compliance across the full power distribution path — from the switchgear room to the rack.
Participants will learn the construction and switching operation of low- and medium-voltage switchgear, referencing the actual product standards (IEEE C37.20 series, UL 1558, NEMA SG-5) that govern switchgear construction and testing. The course then covers the critical distinction between automatic transfer switches (ATS), governed by UL 1008, and static transfer switches (STS), which switch loads in a few milliseconds and are standard at the UPS/PDU level in Tier III and IV facilities.
From there, the course moves downstream to busway and busbar trunking — governed by UL 857 in North America and IEC 61439-6 internationally — finishing at the rack with floor PDUs, rack PDUs (rPDUs), branch-circuit monitoring, and A/B feed redundancy.
