Maintenance Checklist

Checklists written by RokBench that tell you what to look at and where the acceptance criteria are — without reproducing them.

1. What this check does

For the equipment type and class you pick, the checklist lists inspection, electrical test, mechanical and functional items. Each item names the instrument class it needs, adds a field tip where one helps, and points to the documents that hold the acceptance criteria.

2. Inputs used

Equipment type: transformer, switchgear and switchboards, circuit breaker, cable, induction motor, UPS and battery.
Equipment class, such as dry-type or liquid-filled, low or medium voltage.
Optional tag and location for the printed sheet.

3. Formulas and assumptions

Items shown = all items for the equipment type that apply to the selected class Each item = text + instrument class + field tip + document pointers Printed form = checkbox · measured / observed · notes · date · signatures

The checklists are written by RokBench. They do not reproduce the text or tables of NFPA 70B, ANSI/NETA MTS or IEEE standards.
No acceptance or pass/fail values are given, by design. The data structure has no field for them, and an automated check rejects any value that looks like one.
Pointers name the document and section; verify against the edition adopted for the site.

4. What is NOT checked

Maintenance intervals and condition-based frequency.
Site-specific safety procedures, energized work permits and arc flash boundaries.
Manufacturer-specific procedures, which always take precedence.

5. Reference standards

Pointers only; consult the edition adopted by your authority having jurisdiction.

NFPA 70B (2023) — electrical equipment maintenance
ANSI/NETA MTS — maintenance testing specifications
NFPA 70E (2024) — electrical safety in the workplace
