AI drafting for power plans

AI Power Plan Drafting

A power plan is hundreds of small decisions repeated wall by wall: where each receptacle lands, which circuit it rides on, and whether that circuit needs GFCI, AFCI, or a breaker of its own. Nomic drafts the power plan in CAD from your architectural background and furniture plan, circuits it to the panels you name, and checks it against the NEC edition you design to before your engineer reviews.

The problem

Every furniture revision moves the receptacles

In apartments and hotel guest rooms the receptacle layout is a measuring job. No point along the floor line can sit more than 6 ft from a receptacle, any wall 2 ft or wider counts, countertops need a receptacle within 24 in of every point, and the bathroom receptacle goes within 3 ft of the basin on a 20A circuit serving bathrooms. A drafter does that for each unit type, then again for the mirrored and accessible versions, and then tags every bedroom circuit AFCI and every wet location GFCI.

Commercial power follows the furniture plan instead, so the plan changes every time the interior designer reissues one. Floor boxes shift off the table bases, workstation feeds get recounted, and the copier, the break room refrigerators, and the IT rack each need a dedicated circuit someone has to remember. The usual review comments are the same ones on every job: a circuit number used twice, a dedicated load sharing a breaker with general receptacles, a homerun tagged to the wrong panel, and no service receptacle within 25 ft of the rooftop unit.

01 / Layout

Receptacles placed from the furniture plan

Attach the architectural background, the furniture plan, and the equipment list, and describe the sheet you need. Nomic places receptacles, floor boxes, and equipment connections on your power layers with your symbols, and adds the mounting heights your firm notes on the plan.

  • Workstation feeds and floor boxes located from the furniture plan
  • Equipment connections for copiers, appliances, and IT racks
  • Service receptacles at rooftop and mechanical equipment
02 / Circuiting

Circuit tags that match the panel schedule

Nomic circuits the receptacles by room and load using the rules your engineer sets, including how many receptacles go on a circuit, which loads get their own breaker, and which panel serves each area. The homerun tags written on the plan are the same entries that land in the panel schedule, so the two sheets start out in agreement.

  • Receptacle count per circuit held to your firm limit
  • 180 VA per receptacle tallied toward each circuit
  • Homeruns tagged with panel and circuit number
03 / Check

Spacing and circuit rules checked room by room

Before the sheet goes to your engineer, Nomic measures its own layout against NEC 210.52 in dwelling units and guest rooms and checks every circuit against the GFCI, AFCI, and dedicated circuit rules in Article 210. Anything it placed or moved is clouded, and anything it could not resolve is listed as an open question.

  • Wall, countertop, and bathroom spacing measured per unit type
  • GFCI and AFCI tags checked against the room served
  • Conflicts with door swings and casework flagged on the background

Checked against

The code and documents behind every sheet

Name the editions the project is designed to and Nomic checks its own drawing against them before handing it back. Your engineer or architect of record makes the final call and stamps the set.

  • NEC Article 210 branch circuit and receptacle rules
  • NEC 220.14 receptacle load
  • NEC 406.12 tamper-resistant receptacles
  • ADA 2010 Standards 205 and 308 for receptacle heights
  • The project furniture plan and equipment list
  • Your firm circuiting standards

How it works

From a sentence to a stamped set

  1. Step 1

    Ask for the drawing

    Say what the sheet needs to show and attach the backgrounds, markups, cutsheets, or photos. A sentence is enough to start.

  2. Step 2

    Nomic drafts it in CAD

    Nomic works in CAD on its own computer, on your layers and blocks, following how your firm drew the same thing before. It saves real DWG files to the project.

  3. Step 3

    Nomic checks its own work

    The drawing is checked against the code editions you name and the source documents. Everything Nomic drew is clouded, and open questions are listed.

  4. Step 4

    Your team reviews and stamps

    Your engineers and architects review the clouded changes, make the final call, and issue the set under their own stamp.

FAQ

Frequently asked questions

Yes. Nomic works in CAD on its own computer, reads the architectural background and furniture plan, and saves a power plan as a DWG file with receptacles, floor boxes, and equipment connections on your layers. It circuits the devices to the panels you name and checks the result before your engineer reviews it.

Yes, where it applies. NEC 210.52 governs dwelling units, so Nomic measures wall, countertop, and bathroom spacing in every unit type, and NEC 210.60 carries the wall and bathroom rules into hotel guest rooms. Commercial spaces have no spacing rule, so Nomic places receptacles from the furniture plan and your firm standards instead.

Nomic applies NEC 210.8 for GFCI and NEC 210.12 for AFCI based on the room each circuit serves, and gives a dedicated circuit to any load your engineer or the equipment list calls for. Where a cutsheet is missing or a load is unclear, Nomic leaves the circuit open and lists the question instead of guessing.

No. Nomic runs CAD on its own computer and saves DWG files to your project, which open in AutoCAD or any DWG editor. Teams that model in Revit get the DWG and a change list that a modeler links into the model.

Your engineer of record. Nomic is a new source of drafting capacity that lays out, circuits, and checks the plan, and your engineer sets the circuiting criteria, reviews every sheet, and makes the final call before stamping.
