Program guide
How to build an Electrical Maintenance Program, step by step.
The 2023 edition of the standard expects a written Electrical Maintenance Program (EMP) — but it describes requirements, not a build order. This guide is the practical version: six steps, in the order experienced facility teams take them, with the records each step should leave behind. Treat it as the template; the standard itself is the authority.

Step 1 — Scope the program: locations and an equipment survey
Every program is scoped to the places it covers. Start by listing each facility, then walk it. NFPA 70B (2023) Chapter 4 calls for a survey of your electrical equipment to set maintenance priorities: what is installed, where it lives, and what shape it is in. The survey does not need to be exotic — panel by panel, room by room, with nameplate photos as you go.
The records this step leaves behind: a written program document naming the facilities covered, and a completed equipment survey for each one.
Step 2 — Name the people: an EMP Coordinator and Qualified Persons
Chapter 4 expects the owner to designate a single, named EMP Coordinator accountable for running the program — not "maintenance handles it." The coordinator sets priorities, keeps the records current, and delegates authority for the work.
The maintenance work itself belongs to Qualified Persons. OSHA defines a qualified person as one "who has received training in and has demonstrated skills and knowledge in the construction and operation of electric equipment and installations and the hazards involved" (29 CFR 1910.399); NFPA 70E builds on this for safe work practices and calls for retraining at intervals not exceeding three years. Record each person's training and certifications with completion dates — those records are part of the program.
No qualified staff in-house? That is the normal case. Most building owners engage a licensed electrical contractor for the hands-on work and keep the coordinator role in-house — the program still needs the contractor's qualifications on file.
Step 3 — Equipment records: the inventory and the one-line diagram
The backbone of the program is an accurate equipment inventory — every asset with its location, type, and nameplate details — and a one-line diagram of the electrical system (Chapter 6). The one-line matters more than it looks: it is the primary reference for the engineering studies in step six, and it is usually the first thing a loss-control engineer or inspector asks to see.
Panels deserve particular attention: a complete panel schedule, with circuits labeled, supports both accurate maintenance and an accurate diagram.
Keep both current. An inventory that has drifted from reality reads worse than no inventory at all, because it shows the program is not being run.
Step 4 — Put every asset on a maintenance interval
Chapter 9 ties maintenance intervals to equipment class and assessed condition. As a general starting point, switchgear and transformers are typically inspected annually, and motor control centers and distribution panels every one to three years — but the standard's own tables, your equipment's condition, and your engineer's judgment control.
The record this step produces: each asset carries an assigned interval and a next-due date, and the schedule is visible somewhere someone actually looks. Overdue work should surface on its own — not wait for an annual review to notice it.
Step 5 — Record inspections, and track findings to resolution
When maintenance happens, the record must say what was done, when, by whom, and what was found. Chapter 4 expects a documented corrective-action process: every finding gets logged with a severity, assigned, and tracked to resolution. Deferring a finding is sometimes the right call — but deferred is not resolved, and deferred items need periodic review so a postponed issue does not get forgotten.
This is where loose documents typically break down: the value of an inspection record is in its links — this asset, this procedure, this person, this finding, this fix — and scattered files lose those links within a few months.
Step 6 — Engineering studies on file
For commercial systems with significant fault-current potential, NFPA 70B calls for short-circuit and protective-device coordination studies, performed by a qualified engineer — typically a licensed Professional Engineer — and NFPA 70E 130.5 requires an arc-flash risk assessment. These are PE-stamped engineering deliverables; software does not compute them, and neither do you.
The program's job is narrower: keep copies on file, know the refresh cadence, and flag the trigger conditions that should prompt a re-study — a new transformer, a major load addition, replaced switchgear.
Putting it together
Run the six steps in order and you end up with exactly the file a reviewer asks for: a written program, named roles with training records, an inventory and one-line diagram, a live maintenance schedule, dated inspection records with findings tracked to resolution, and current studies.
That file is the program. The standard is, at bottom, a specification for records that show the work is happening — which is why the fastest way to check your own program is to check the records it can produce today.
