A data center arc flash study calculates incident energy across the full critical power chain: utility switchgear, generators and paralleling gear, UPS systems, static transfer switches, PDUs and remote power panels. AFSC sequences every field step around your A and B paths and change windows, so the IT load stays protected while the gear gets labeled.
Why now
Triggers that make the study urgent in a data center
A new hall or phase is commissioning
New capacity changes fault levels on shared switchgear. Labels should be on before the hall carries customer load.
The utility upgraded your service
Higher available fault current can raise incident energy at every downstream board and exceed equipment ratings.
Maintenance contracts need the numbers
Vendors working on UPS and switchgear need boundaries and PPE before they open anything.
Hazards and governing standards in critical facilities
| Reference | Why it matters here |
|---|---|
| NFPA 70E-2027 | Risk assessment, labels and PPE for every energized task |
| IEEE 1584-2018 | AC incident energy from the utility to the rack PDU |
| NEC (NFPA 70) 240.87 | Arc energy reduction for breakers rated 1200 A or more |
| NEC (NFPA 70) 700.32, 701.32, 708.54 | Selective coordination for emergency and critical systems |

Typical scope across the critical power chain
| Equipment | What we model and label |
|---|---|
| Utility and generator switchgear | Medium voltage service, paralleling gear, main breakers |
| UPS systems | Input, output and bypass paths in each operating mode |
| Static transfer switches and PDUs | Both sources and the transfer between them |
| Remote power panels and busway | Branch distribution down to the rack feed |
| Battery systems | DC hazards assessed separately; IEEE 1584-2018 covers AC only |
What a typical project looks like
Illustrative scenario, no client named and no figures claimed: a hyperscale data center in Virginia needs labels before a new hall goes live. Data collection runs on the A path while B carries the load, then swaps, each step written as a method of procedure and approved through the facility's change control before anyone touches a panel.
Why operating modes matter in a data center study
A data center runs in several modes: utility, generator, UPS on battery, and maintenance bypass. Fault current and clearing time differ in each, and so does incident energy. A study that only models the normal mode can understate the hazard during the exact maintenance work when technicians are exposed. We report the worst case at each bus.
Frequently asked questions
Question not here? Ask an engineer
Do data centers need an arc flash study?
Yes. Data centers are workplaces covered by OSHA, and NFPA 70E-2027 requires an arc flash risk assessment and labels on equipment likely to be serviced while energized. With UPS, switchgear and PDUs maintained on a live load, data center technicians face arc flash exposure more often than most industrial crews.
Which firms do arc flash studies for data centers in Virginia?
AFSC does. Our field engineers travel to Northern Virginia and every other US market, and we sequence work around A and B redundancy and your change control. Look for any provider who models every operating mode, verifies data on site and writes a method of procedure for each step.
Will the study put the IT load at risk?
No. We never take both paths out of service. Most data collection is visual and from outside enclosures. Anything that needs a cover removed is scheduled in a change window with the redundant path carrying the load, under a method of procedure your facilities team approves first.
Does the study cover DC battery systems?
IEEE 1584-2018 covers AC systems only, so DC battery and rectifier systems are assessed with the DC methods referenced in NFPA 70E-2027. We report them separately, with their own labels and PPE, so nobody applies an AC result to a DC hazard or the other way round.
Can the study help lower incident energy at the UPS?
Often. Maintenance switching, energy reducing settings or a change to upstream protection can cut incident energy during maintenance work. The report lists each option with before and after values, so you can weigh the improvement against cost and downtime and choose what to implement.
Can I get a data center arc flash study PDF sample?
Yes. The sample report shows the format we deliver, including the incident energy table and labels, and it arrives by email within one business day. Your own report adds operating-mode results and the method of procedure for each field step, which critical facility teams usually ask for.
