Engineering guides on power distribution for AI and high-density facilities — one-line diagrams, architecture comparisons, code guidance, and specification advice from the team at Arkhon Power Group. New guides published regularly.
AI compute broke the assumptions that data center electrical design ran on for twenty years. Racks that drew 5–15 kW now draw 120 kW and are headed toward a megawatt. These guides work through the design decisions that shift as a result — distribution architecture, voltage class, equipment selection, protection, and procurement — written for the consulting engineers, contractors, and owners making those calls on real projects.
Enter rack density, row length, topology, and transformer data — get tap-off ratings, busway frame selection, voltage drop, and available fault current instantly. Supports 2N, 4-to-make-3, and 1N with NEC 125% continuous duty. Copy the summary into your design narrative.
Open the calculatorWhy RPP-based distribution hits a wall around 40 kW/rack, and how track busway carries AI clusters to 120 kW and beyond. Includes full A+B one-line diagrams, elevation views, tap-off sizing, transformer selection, and a 16-point engineering comparison matrix.
Read the guideRacks are headed from 120 kW toward 1 MW, and the 480V distribution chain can't follow. How MV is getting closer to the rack — pod substations today, solid-state transformers and 800V DC tomorrow — plus protection, insulation, redundancy, and lead-time planning.
Read the guide800VDC will reach only 15–25% of facilities by 2030 — concentrated in megawatt-scale AI training clusters, mostly as side-car designs. An honest pros-and-cons of 800V design, the new-build vs. retrofit decision framework, and why track busway is the distribution layer that serves both sides of the transition.
Read the guideStructured hot aisle containment modules — busway, Cablofil tray, and liquid cooling piping integrated offsite — are cutting white-space schedules 30–50%. How they work, what to specify, and why the power distribution choice inside the module decides whether prefab delivers.
