Busway quarterly maintenance checklist
A quarterly busway (bus duct) round is short on purpose: it catches the wear items that fail between annual services. This checklist is sized for a tech with a phone. Every item says what to look at and the photo that proves the round happened. Work is commonly verified against NFPA 70B, NETA maintenance testing standards. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The facility electrician walking the run on the quarterly round, scanning and looking with the busway energized.
When in the schedule
Every quarter, walked under load so the joint scan catches a warm bolted connection while current is actually flowing.
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.
Joints and heat
- 2 photos
Bolted joints scanned along the run
Thermography or a non-contact scan at each accessible joint and elbow, no single bolted connection reading hot against the adjacent housing.
- 1 photo
Housing checked for discoloration and heat marks
No paint discoloration, blistering or heat staining at joint covers, no burnt smell along the run.
Support and plug-ins
- 1 photo
Hangers, supports and alignment checked
Hangers tight and evenly spaced, run straight without sag or twist at joints, no support carrying a pipe or other load it wasn't meant to.
- 2 photos
Plug-in units seated and latched
Each plug-in fully stabbed, latched and interlocked, no unit hanging crooked off the run or leaking heat at the stab.
Moisture and grounding
- 1 photo
Run checked for moisture and condensation entry
No dripping pipe, roof penetration or condensation landing on the housing, no water staining at joints where a run passes below wet areas.
- 1 photo
Ground continuity connections intact
Grounding straps and bonding jumpers across joints landed and unbroken, no corrosion at the ground path along the run.
What usually sends this back
The failures are almost always the evidence, not the work
- A joint running warm at a ceiling elbow that never gets scanned because the run is twenty feet up and out of easy reach.
- A plug-in unit stabbed on crooked and left, so the stabs arc quietly until the joint discolors.
- Condensation dripping onto the housing from a pipe or roof penetration above the run, unnoticed until it tracks across a joint.
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 8 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 busway quarterly checklist cover?
- 6 items across 3 sections, covering joints and heat, support and plug-ins, moisture and grounding. 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?
- The facility electrician walking the run on the quarterly round, scanning and looking with the busway energized.
- When in the schedule should this walk happen?
- Every quarter, walked under load so the joint scan catches a warm bolted connection while current is actually flowing.
- Why does every item ask for a photo?
- 8 of the 6 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 busway quarterly inspection?
- A joint running warm at a ceiling elbow that never gets scanned because the run is twenty feet up and out of easy reach. A plug-in unit stabbed on crooked and left, so the stabs arc quietly until the joint discolors. Condensation dripping onto the housing from a pipe or roof penetration above the run, unnoticed until it tracks across a joint.
- 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.
