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:
- Reads every fixture across every wall in the project (and every sibling project sharing this panel, for home-attached projects).
- Identifies fixtures that aren’t yet assigned to any breaker on the panel.
- 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.
- Asks you to confirm in a modal that reminds you the result is a best-effort guess, not a stamped design.
- 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:
- Undersized breaker for a heavy load (e.g. 16 A breaker assigned to an EV charger)
- Missing dedicated circuit where the region requires one (kitchens in DIN 18015 mode, bathroom 20 A radial in NEC mode)
- Wet-room fixtures on circuits without GFCI/RCD protection
- Solar inverters paired with the wrong RCD type
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:
- Cover header (project title + meta) matching the Renovation Brief visual style
- Panel Directory table: position, label, amp rating, curve type, calculated load, notes — one row per breaker
- Warnings section, colour-coded by severity, only if there are any
- Your panel notes (if you’ve added any)
- Footer disclaimer
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.
