Main electrical switchgear / service section annual maintenance checklist
The annual main switchgear service is the deep pass — the measurements, cleanings and tests a quarterly round doesn't reach. This checklist keeps the full service on record with the photos that make it defensible later. Work is commonly verified against NETA guidance, NFPA 70B — confirm the edition your authority having jurisdiction has adopted.

Who runs it
A qualified electrical testing crew, coordinated with facilities for the required outage.
When in the schedule
Once a year, scheduled well ahead of time since it requires de-energizing the section and an approved outage window.
The checklist
Every item, and the photo that proves it
The photo count on each row is what RTI would require before the item can be submitted. Copy the list as-is, or load it into RTI and let the gate enforce it.
Preparation and access
- 1 photo
Section de-energized, locked out and verified with a meter
Zero energy confirmed at all accessible conductors before any panel is opened.
- 2 photos
Interior compartments opened and cleaned
Dust, debris and any signs of pest intrusion removed; compartments vacuumed, not blown, to avoid spreading dust.
Connections and insulation
- 3 photos
Bus and cable connections inspected and torqued
No discoloration or pitting at lugs and bus joints; connections torqued to the documented value.
- 1 photo
Insulation resistance tested on major components
Megohm readings recorded per component and compared against baseline or manufacturer minimums.
- 1 photo
Insulating barriers and supports checked for tracking or cracking
No carbon tracking, chalking or physical damage on standoffs and barriers.
Breaker exercise
- 2 photos
Each breaker manually exercised open and closed
Mechanism operates smoothly without binding, trip and close indicators function correctly.
- 1 photo
Protective relay settings and trip units reviewed
Settings match the current coordination study, not the panel's out-of-date factory defaults.
What usually sends this back
The failures are almost always the evidence, not the work
- Outage window cut short and only half the sections opened and inspected as planned.
- Discoloration on a bus connection noted but not re-torqued or measured for resistance.
- Breakers never actually exercised open-closed, just visually inspected sitting in one position.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 11 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.
Submission state
The gate is enforced on the server, so it holds even if the phone is offline when the walk happens.

Common questions
- What does this main electrical switchgear / service section annual checklist cover?
- 7 items across 3 sections — preparation and access, connections and insulation, breaker exercise. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
- Who should run this inspection?
- A qualified electrical testing crew, coordinated with facilities for the required outage.
- When in the schedule should this walk happen?
- Once a year, scheduled well ahead of time since it requires de-energizing the section and an approved outage window.
- Why does every item ask for a photo?
- 11 of the 7 items call for photo evidence. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
- What most often fails a main electrical switchgear / service section annual inspection?
- Outage window cut short and only half the sections opened and inspected as planned. Discoloration on a bus connection noted but not re-torqued or measured for resistance. Breakers never actually exercised open-closed, just visually inspected sitting in one position.
- Can I use this checklist in RTI?
- Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper-evident audit trail.
