Maintenance without a maintenance window
There’s no good time to take gear offline when the floor runs 24/7. Every service task has to be planned around concurrent maintainability so one path can be worked while the other carries the full load.

The Reality On Site
What facilities managers in data centers deal with.
When availability is the product, every electrical decision is a risk decision. These are the pressures your team lives with.
Transfer switch and STS uncertainty
You need to know your automatic transfer switches and static transfer switches will actually transfer under load, not just on paper. Testing that without dropping a single rack takes a crew that has done it before.
Nobody accountable at 2am
When a PDU trips or a feed faults in the middle of the night, you don’t want three vendors pointing at each other. You want one accountable team that knows your one-lines and owns the outcome.
Standards & Compliance
The standards your uptime depends on.
Data center electrical work lives and dies by availability and safety standards. We work to the frameworks your operations and your auditors already hold you to.
Uptime Institute Tier Standards
Concurrently maintainable and fault-tolerant work practices that protect your Tier III and Tier IV commitments.
NFPA 70 (NEC)
National Electrical Code compliance across distribution, grounding, and equipment installation.
NFPA 70E
Electrical safety in the workplace, including arc flash boundaries and PPE requirements for energized work.
NETA Maintenance Testing
Acceptance and maintenance testing standards that verify gear performs to spec, not just passes a visual check.
IEEE 1584
Incident energy analysis that puts a real number on arc flash risk at every point in your system.
ANSI/TIA-942 Awareness
Infrastructure standards context so our electrical work aligns with your facility design intent.
How We Help
How BASS MCS serves data centers.
Energized maintenance & arc flash support
Much of what a live data center needs done can’t be de-energized. We run IEEE 1584 incident energy analysis and NFPA 70E labeling so your team and ours can work energized gear at known, documented risk levels.
Transfer switch & A/B feed testing
We test ATS, STS, and dual-feed paths one side at a time, confirming failover behavior while the redundant path carries the load. You get proof your redundancy works before you need it.
PDU and distribution inspection
Infrared scanning and connection checks on PDUs, RPPs, and busway catch the loose lugs and hot spots that turn into unplanned outages, all while the floor stays energized.
Same-crew accountability
The team that inspects and documents your system is the team that shows up when something faults at 2am. No handoff, no relearning your topology under pressure.
