List the loads — critical, emergency, legally required, optional — and the engine sizes the switchgear, transfer switches, UPS, generators and battery storage together, checks every capacity after N+1 or 2N, and prices the package as one bill of materials. Every number comes from the rules, never from a guess.
Power packages — NEC 700, 701 and 702 loads on separate transfer switches, every capacity checked after redundancy before pricing.
Switchgear, automatic transfer switches (UL 1008), UPS frames, modules and batteries, diesel generators with fuel storage, step-down transformers and battery storage cabinets — at 480 V or 4,160 V service, under N, N+1 or 2N.
Load classes kept apart: emergency (NEC 700), legally required (NEC 701), optional (NEC 702) and critical UPS loads each get their own transfer switch, sized to that class. UPS, generator, transformer and switchgear capacity are checked after redundancy, with losses included.
Each capacity used against provided — generator kW for the backed loads, UPS kW for the critical load, amps on each transfer switch — plus the site facts the package depends on (service voltage, available fault current), stated rather than buried.
Cited rules decide what may be built and how it must be split — and every size, price and refusal shows its source.
Free to use — Nteli is paid only when an order is won through it.
A power package built in a spreadsheet goes stale the day one of these shifts. The engine doesn’t watch for changes — people teach it: a change comes in with its source, gets replayed against past quotes to show what it touches, is approved by a second person, and ships in a versioned pack. Your quotes cite the rule that priced them.
Articles 700, 701 and 702 decide which loads share a transfer switch and which never may — and they move on the code cycle.
Emergency power supply systems carry their own levels, run times and testing — a hospital wing is not a warehouse.
Battery storage brings its own siting, spacing and fire-protection rules — indoors and outdoors are different quotes.
Generators, switchgear and transformers ship on long lead times, so a quote priced on last year’s rules is delivered under next year’s.
The engine is a full MCP server — connect it to Claude and your team quotes power packages in plain conversation: list the loads, answer the question card, review the sized package. The starter rule pack ships with the line; override it with your own rules, governed and audited — and you're onboarded.
Connect the engine as a custom connector (two steps, shown here), then paste any of these. They were run on the live engine; prices are illustrative until your price book loads.
What you’ll see: The engine won’t call it ready: generator capacity for the backed loads is 60 kW needed, 0 kW available. The fix is priced next to it — add one generator, about $177,000 — and it stays the customer’s call.
What you’ll see: Five 50 kW UPS modules, two 500 kW generators, a 300 kVA step-down transformer, 800 A / 65 kA switchgear and a transfer switch per load class (emergency 100 A, critical 400 A, optional 225 A) — about $671,000 with engineering, and every capacity inside its limits after redundancy.
What you’ll see: One 1,012 kW generator for 710 kW of backed load, 1,600 A switchgear, separate 600 A transfer switches for the NEC 701 and NEC 702 loads, and two 125 kW / 261 kWh battery cabinets — about $733,000 with engineering.
