Acceptance, maintenance and commissioning documentation for LV power (LVPCB), air (ACB), insulated-case (ICCB) and molded-case (MCCB) circuit breakers. Records as-found / as-left values side by side, evaluates each result against the limits you enter, and rolls every exception up into a single deficiency summary. Data stays in this browser; export JSON to archive or CSV to analyse, and print for client delivery.
Final acceptance criteria must be verified against the current licensed standard, manufacturer published data, the coordination study, customer specifications, and AHJ requirements. Reference-limit fields are user-editable and no copyrighted standard tables are embedded. NEC references are reproduced as prompts for the technician, not as a substitute for the adopted code text. De-energize, lock out, and verify absence of voltage before testing.
Select the basis for this test. Acceptance criteria are defined by the referenced standard or manufacturer data, not by this tool.
Category, poles and trip functions drive which test rows appear below. Frame ≥ sensor ≥ rating plug is checked for consistency.
Marking a function “Not present” removes its settings and injection-test rows from the record. Leave blank if not yet determined.
Applies to drawout / power circuit breakers. Record dimensional data per the manufacturer's published values. As-left operation count must be at or above as-found.
Items are filtered by equipment category and mounting. Mark each Pass, Fail, N/A or Not Tested. Any Fail — or a Deficiency flag — is carried to the Deficiency Summary.
| Component / Activity | Status | Deficiency | Notes | Corrective Action |

As-found differences from specified are recorded as observations. As-left differences are deficiencies unless an approved deviation with a reference is entered. Numeric values are compared by value, so 1, 1.0 and 1.00 are equal.
| Parameter | Spec Source / Coord Ref | Specified | As-Found | AF vs Spec | As-Left | AL vs Spec | Approved Dev. | Approval Ref. |

Each row: set State (Perform / N/A / Not Tested), enter the acceptance band (Min/Max, a one-sided limit, or a nominal value plus Tol %), then record measured values. Pickup rows are judged on measured pickup, delay rows on measured time. A row with measurements but no limits shows REVIEW — never PASS.
Enter the manufacturer's maximum permissible pickup voltage as Max; the coil must operate at or below it. Blank Min means “no lower bound”.
| Parameter | State | Rated V | Min | Max | Tol % | Ref/Source | Measured AF | Measured AL | Unit | Result | Notes |

Pass/Fail compares each reading against the manufacturer minimum, or the user-entered reference minimum. If no minimum is provided the reading shows REVIEW rather than PASS. No copyrighted table values are embedded — enter the minimum from your referenced standard or the manufacturer's data.

Disconnect or bypass solid-state trip units, surge devices and other electronics before applying test voltage to control circuits.
Compared against the manufacturer limit when entered. If limits are blank each pole is compared to the lowest measured pole, and a deviation greater than 50 % raises INVESTIGATE. This is an investigation trigger, not an automatic failure, unless the chosen procedure requires it. Temperature normalization must not override manufacturer acceptance criteria unless the procedure specifies it.

Two NEC requirements produce records that belong in a breaker test report: the ground-fault protection performance test required at installation, and the arc energy reduction performance test. Applicability is declared by the technician — this tool prompts, it does not determine compliance. Verify against the code edition adopted by the AHJ.
GFPE applies to solidly grounded wye services and feeders of more than 150 V to ground, not exceeding 1000 V phase-to-phase, where the disconnect is rated 1000 A or more. Where it applies, the maximum setting is 1200 A and the maximum time delay is 1 second for ground-fault currents of 3000 A or more.
Where the highest continuous current trip setting for which the installed overcurrent device is rated or can be adjusted is 1200 A or higher, an arc energy reduction method is required, and the system must be performance tested when first installed with a written record retained.
Runs non-destructive logic checks. Your current form data is snapshotted and restored when the run completes. Results are also written to the browser console.
