Generation to rack: power path N-1
A utility source, an MV loop, one padmount transformer and LV lineup per rack row, CDUs and a chiller and pump yard, drawn as an isometric hall and as a one-line diagram. Play five stories, or switch to free play, build a hall from exported options and click any element to fail it: the branch it feeds goes dark in both views, the IT-loss number appears, the N-1 checks flip and the surviving transformers load up.
Story
Free play · build a hall, then click anything to fail it
Representative halls · the ones failure data exists for
Rack rows (one lineup and one padmount each)
Racks per row
kW per rack · illustrative
Chillers · duty + standby
Pumps · duty + standby
CDUs per row
Transformer policy
Every control snaps to a value the harness was run at; the page reads that cell and never estimates between two. Rack, chiller, pump and CDU sizes are round illustrative placeholders, not equipment data.

One-line diagram · the same hall, click any symbol or run
Source and MV loop at the top, one padmount transformer and LV lineup per rack row, each lineup feeding its rack row, its CDUs and the chillers and pumps assigned to it. Bars: loading, % of that transformer's nameplate (dashed ticks: the design limit the data states and 100 %).

Every check at this state · the controlling row is highlighted
Rule column: the citation the data file gives for each check. The 80 % design limit is the harness's draft design basis, not a published standard.
How the checks read it
Every check · before the event, the event, the fix
Required values are read from the data file. Tight is the harness's warn (partial capacity), not a failure. Rows tagged demo logic are this demo's own counting over the harness one-line; rows tagged harness are the harness's results.
build_generic_hall, build_load_schedule, build_one_line, pick_transformer_kva.Not modeled: backup generation or batteries, protection and relay coordination, cable ampacity and fault withstand (circuit-calc-harness territory), a real cooling load model, CDU-level redundancy, transformer re-sizing after an event (nameplates stay as picked), and any real site layout. The drawing is schematic: hall, yard and loop geometry are illustrative.See also:Power path N-1, hands-off walkthrough · Cooling capacity margin · K-of-N availability
