Permit-Ready Electrical Report

Engineering-grade system documentation aligned to ABYC E-11, NEC, or CSA C22.1 (CEC). Ready for installer use, surveyor review, and as the supporting design package for a P.Eng / PE stamp. Not a PE-stamped permit document on its own.

Wire-run lengths are typical defaults

The conductor schedule in the PDF prints with default trunk lengths (battery 6 ft, solar 20 ft, controller→battery 6 ft, inverter DC 5 ft, inverter AC 8 ft, AC mains 15 ft) flagged with an asterisk and an explicit footnote. For best accuracy on long or unusual runs, model your actual lengths in the Wiring tab of your project — the installer or P.Eng will re-size if needed before final installation.

What is in the report

Every section below is generated from your project data — voltages, loads, chemistry, jurisdiction. The numbers, citations, and conductor sizes change per project.

  • Cover page + executive summary
    Project name, system voltage, jurisdiction, document ID. Branded MPL diamond mark.
  • Engineering-grade single-line schematic
    IEC 60617 / ANSI Y32.2 / ABYC E-11 symbol library. Battery cell count scales with chemistry × voltage. Reference designators (PV1, MPPT1, B1, F1, F2, F3, CB-MAIN, CB-AC, INV1).
  • 24-hour load profile chart
    Stacked-area Wh/h × 24 hours, computed from your actual loads. Per-category daily-Wh totals in the legend. Peak-hour callout.
  • Load schedule (continuous vs non-continuous)
    125% demand factor on continuous loads (≥3 hr/day) per NEC / CEC / ABYC convention. Total demand-factored watts and amps at system voltage.
  • Battery bank sizing — full math shown
    Chemistry-specific DOD, days of autonomy, temperature derate. The numbers behind your recommended Ah, not just the result.
  • Solar / inverter sizing
    Peak-sun hours, loss factor, controller sizing. Inverter continuous + surge with diversity factor for AC-mixed systems.
  • Conductor schedule with heat-dissipation transparency
    Every trunk wire sized for ampacity AND voltage drop. Gauge, base ampacity, derating factors (ambient × bundle × material), and chosen fuse rating per run.
  • Overcurrent protection schedule
    Device IDs (F1 / F2 / F3 / CB-MAIN / CB-AC), location rules per ABYC E-11 §11.10 / NEC 240.21(C), minimum AIC ratings.
  • Component bill of materials
    Picked from the PowerLab component catalogue against your project shape. Each component carries its compliance certifications (ABYC, NEC, UL, CSA, CE, RoHS).
  • Wire color-code legend
    Jurisdiction-specific conductor colors keyed to your code (ABYC E-11 §7, NEC §200.6 / §210.5, CSA §4-036). The schematic is B&W; this legend tells the installer what colors to use.
  • Maintenance schedule
    Per ABYC E-11 §11.18 — periodic checks for terminals, electrolyte, fuse condition, ground continuity. NEC and CSA equivalents cited where applicable.
  • Standards conflict resolver
    Where NEC and ABYC give different guidance (e.g. battery OCPD location), the report shows both with their respective citations and flags which applies to your jurisdiction.
  • Compliance disclosure
    Plain-language statement of what this document is and what it is NOT — see "What it is not" below.
  • Sign-off blocks
    Spaces for the buyer, the licensed electrician, and the AHJ to sign and date. Not a stamp — the AHJ + electrician add those.

Three jurisdiction options

Pick the code your AHJ enforces. The report cites the right sections, looks up the right ampacity tables, and uses the right conductor color code.

United States — NEC / NFPA 70

  • ·Ampacity per Table 310.16 (raceway, 30 °C ambient)
  • ·Overcurrent protection per Article 240
  • ·Solar PV per Article 690
  • ·Energy storage per Article 706
  • ·Grounding & bonding per Article 250

Canada — CSA C22.1 (Canadian Electrical Code)

  • ·Ampacity per Table 2 (raceway, 30 °C ambient)
  • ·Overcurrent protection per Section 14
  • ·Renewable energy per Section 64
  • ·Bonding per Section 10
  • ·Conductor identification per §4-036 / §4-038

Marine — ABYC E-10 / E-11

  • ·Ampacity per ABYC E-11 Table 4 (free-air, 30 °C ambient)
  • ·Battery & cable per E-11 §11.5 / §11.6
  • ·Overcurrent location per E-11 §11.10
  • ·Maintenance per E-11 §11.18
  • ·Galvanic corrosion + bonding per E-11 §11.16

How to read this

Each report is auto-generated from your specific project data — this is the system documentation. A licensed electrician (or P.Eng / PE where your AHJ requires it) reviews the calculations, stamps where applicable, and signs off on the installed work. PowerLab handles the math + format; the human in the loop carries the legal authority.

What it is not

  • ·A PE-stamped (P.Eng) permit document on its own. It is the design rationale a licensed engineer reviews and stamps when your jurisdiction requires one.
  • ·A stamped engineering drawing — your AHJ may require an electrician's stamp before final acceptance.
  • ·A substitute for an on-site inspection. The report describes the design; the installer wires it; the inspector verifies the build.
  • ·A guarantee of permit approval. Different AHJs and jurisdictions have different requirements; this document gives you a clean starting point.
