How to brief an electrical commissioning search
Define the electrical systems, commissioning levels, site responsibilities and travel terms before hiring for a US data center build.
01
Define the power-system boundary
Switchgear acceptance testing, UPS functional testing and a campus-wide integrated systems test require different experience. List the voltage classes and equipment families in scope. Explain whether the engineer joins an independent commissioning provider, an electrical contractor or an owner team.
Vertiv's commissioning guidance distinguishes component acceptance testing and vendor start-up from the broader commissioning process. A candidate who has supported one should not automatically be treated as having led all three.
- Equipment: switchgear, UPS, batteries, generators, transfer switches and distribution, as applicable.
- Level: factory witness, installation verification, start-up, functional testing or integrated testing.
- Ownership: witnessing, executing an approved script, writing scripts or directing the test.
- Interfaces: OEM technicians, protection specialists, controls integrators and operations.
02
Ask for one traceable example
A useful interview starts with one power path the engineer can explain without identifying a confidential client. Ask what was meant to happen, what evidence they recorded, what differed from the script and who authorized the retest.
Record personal responsibility separately from the size of the campus. Being present on a large site does not establish ownership of every system on it. Ask for the tested scope in megawatts where the engineer can disclose it.
03
Make the offer workable before interviewing
Include site location, anticipated start, rotation, expected hours, employment type and the approved pay range. State whether travel, accommodation and per diem are provided and how changes to the schedule are handled. These are search requirements, not details to discover after an offer.
Quick answers
Common questions
- Does switchgear testing experience prove IST leadership?
- No. Component testing and leading an integrated test are different responsibilities. Ask separately about cross-system scenarios, script ownership and authority during the test.
- Should every electrical role require L5?
- Only if the actual assignment needs it. A precise L2–L4 role can be better briefed than an undifferentiated requirement for every level.
