NEC electrical plan review

The NEC is the code behind electrical review. PlanFlag checks that the schedules and one-lines agree with each other and carry what they should.

What PlanFlag checks against the NEC

• Panel schedules: circuit, load, and feeder fields checked for completeness and internal consistency.
• Load arithmetic: connected and demand load totals checked against their line items.
• One-line consistency: equipment and feeders on the one-line reconciled against panel schedules and plans.
• NEC edition: the cited edition is consistent across the set.

Three tiers of depth

Essential runs a single best-in-class pass for a fast, affordable first read. Professional adds a reasoning pass that weighs findings against each other and drops false positives. Flagship layers cross-sheet reasoning, table/schedule analysis, and visual verification on top: the deepest coverage for high-stakes sets. The same findings get a deeper verdict as you move up; depth means coverage, not more noise.

Where the engineer stays in control

PlanFlag surfaces candidate findings for a licensed professional to evaluate. It does not perform engineering, and it does not seal, stamp, or approve anything. The engineer of record remains solely responsible for the design, and the reviewing professional remains responsible for every decision to act, or not act, on a finding. A clean or short report is not evidence that a set is complete or compliant; it describes only what was assessed.

The goal is the disciplined review a good reviewer already does: "here is what should be on this sheet, let me find it, and let me investigate the unexpected," run consistently and fast, with receipts.
