From electrician to data center commissioning

Most of what a commissioning technician touches on the electrical side is equipment a data center electrician installs: medium-voltage and low-voltage switchgear, transformers, UPS modules, ATSs, PDUs, remote power panels, busway and generator connections. Reading one-line diagrams and panel schedules, terminating and torquing conductors, phasing, and following lockout/tagout and energized work permits all carry over directly.

• ●Reading one-line diagrams, riser diagrams and panel schedules
• ●Medium-voltage and low-voltage switchgear installation and terminations
• ●UPS, ATS, PDU, RPP and busway installs
• ●Generator and load bank cable connections
• ●Insulation resistance (megger) checks and torque verification
• ●Lockout/tagout and energized electrical work permits under NFPA 70E

Commissioning managers judge technicians by their test records. That means following a test script step by step, writing down every reading, and flagging anything that does not match the design.

The second gap is system behavior. At Level 4 and Level 5 the team tests what happens when utility power drops, the UPS carries the load, the ATS transfers and the generators pick up. You need to explain that sequence in your own words. Our commissioning levels guide walks through each level.

• ●Running a written test procedure without skipping steps
• ●Recording readings and pass/fail results on test forms or in a Cx software platform
• ●Explaining a utility failure and transfer sequence from the one-line
• ●Logging issues and following them to closeout with the contractor

The realistic first role is electrical commissioning technician. Commissioning technicians who learn to write and run Level 3 to 5 tests move up to commissioning engineer. The commissioning agent who leads the team onsite usually has 10 or more years in commissioning. Expect heavy travel, early starts and overtime near deadlines.

The commissioning technician role page lists OSHA 10 or 30 and NFPA 70E as required and NETA certification as helpful for electrical work. A state journeyman license is already strong proof of trade experience.

• ●OSHA 10 or OSHA 30 Outreach card. OSHA describes the card as proof you completed the training.
• ●NFPA 70E electrical safety training. 70E is the standard for electrical safety in the workplace; employers provide or require training to it.
• ●NETA Electrical Testing Technician certification, Level II and up, if you plan to stay on the electrical testing side
• ●Your state journeyman license, listed with the license number and state

Name the equipment and the tests. For example: "Terminated and meggered switchgear feeders, connected load banks for generator testing." Only list what you did yourself. If you supported testing, say "supported".

When you are ready, join our talent network. Tell us your license, the equipment you have worked on and the metros you would work in.

• ●Equipment by type, voltage and size, such as medium-voltage switchgear, UPS modules and ATSs
• ●Tests you ran or supported: insulation resistance, torque checks, phase rotation, load bank connections
• ●Data center, hospital or other mission-critical projects by type (no client names needed)
• ●OSHA card, NFPA 70E training date, state license number
• ●Willingness to travel and work extended hours, stated plainly
