Circuit Panel (Pro)

The Circuit Panel sheet is where you turn a wall full of fixtures into a coherent breaker layout. Add each breaker manually, or hit the wand to auto-fill from every fixture you’ve placed across every wall.

What the panel does

Every WireSketch project, or every project inside a Home, has one Circuit Panel sheet. The sheet lists each breaker as a row: position, label, amp rating, curve type, and free-text notes. Each breaker shows the fixtures currently assigned to its label by matching Fixture.circuitID to the breaker name.

Add a breaker manually with the “+ Add breaker” button. Edit any row inline. Delete with a tap and confirmation. Reorder with drag.

The wand: auto-fill from your fixtures

The wand (“Add missing breakers”) is the feature most people use the panel for. Tapping it:

  1. Reads every fixture across every wall in the project (and every sibling project sharing this panel, for home-attached projects).
  2. Identifies fixtures that aren’t yet assigned to any breaker on the panel.
  3. Generates breakers to cover them, kitchen appliances each get a dedicated circuit, EV chargers get the right amperage, bedrooms and living rooms get grouped sensibly.
  4. Asks you to confirm in a modal that reminds you the result is a best-effort guess, not a stamped design.
  5. Appends the new breakers to the existing panel. Your existing breakers and assignments are never touched.

Tap the wand again after adding more fixtures, it tops up. Tap it on a fully-covered panel and you get a banner saying “Every fixture already has a matching breaker” instead of duplicate breakers.

Live load and code warnings

Each breaker row shows its calculated load (sum of assigned fixture watts ÷ nominal regional voltage). When the load exceeds the breaker’s amp rating, the row turns red and a warning surfaces. Other warnings the engine flags:

Multi-panel layouts for larger homes

For homes with a separate garage panel, basement sub-panel, or addition, you can add multiple panels to a Home and assign each project to the right one. Live totals at the home level summarise projects-per-panel, fixtures-per-panel, and expected load-per-panel.

The Panel Report PDF

One tap exports a printable Panel Report, an A4 PDF with:

Email it to your electrician, file it alongside the Renovation Brief, or print it for the install crew.

What it isn’t

The auto-fill is a guess, not a design. The wand uses regional defaults (DIN/BS/NEC/AS‑NZS) to suggest breakers for the fixtures you’ve placed. It doesn’t calculate loop impedance, doesn’t simulate selectivity, doesn’t check conduit fill, and doesn’t auto-flag AFCI in US dwellings (yet). A licensed electrician must verify the panel layout before any installation work.

Pro feature

Circuit Panel, the wand auto-fill, and the Panel Report PDF are all part of WireSketch Pro, one-time purchase, no subscription. The free tier includes the editor and Homes; Circuit Panel is a Pro unlock.

Important. WireSketch produces a planning and design artefact, not a compliance document. Standards are modelled at their baseline, local amendments apply, and final certification of any installation must come from a licensed electrician operating under your jurisdiction’s adopted edition and amendments.
