What does this busway annual checklist cover?

14 items across 5 sections, covering isolation and access, joint torque, run and supports, testing observed and recorded, and more. 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 recording the inspection during a planned outage, checking joint bolts while the testing firm performs the electrical tests on the run.

When in the schedule should this walk happen?

Once a year during a scheduled shutdown, coordinated with the NETA technician so the busway is locked out and joint covers opened while it's dead, then tested before the run is re-energized.

Why do these items ask for a photo?

8 of the 14 items call for photo evidence, 12 photos in all. 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 annual inspection?

Joint bolts checked only at the ground-level sections while the high joints that the quarterly scan flagged as warm get skipped again. A belleville-washer joint torqued flat like a standard bolt, over-compressing the stack instead of setting it to the manufacturer's spec. Covers reinstalled and the run re-energized before the testing tech's insulation readings across the run are recorded.

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.

Busway annual maintenance checklist

The annual busway (bus duct) 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 NFPA 70B, NETA maintenance testing standards. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Isolation and access

Owner told which floors and loads lose power
Written outage notice agreed with the owner: panels, floors and any plug-in loads that go dark, the window, the restore order and any temporary feed needed.
No photo
Every feed to the run identified for lockout
Source breaker, any tie or alternate feed and anything that could backfeed the run listed and locked, with the utility coordinated where it is service busway.
No photo
Busway locked out and verified dead
Feed isolated, absence of voltage tested at the run, lockout applied before any joint cover is opened.
Joint covers opened and joints inspected
Bolted joints exposed and cleaned of dust, no discoloration, deformation or moisture staining on the bars, insulators clean and uncracked.

Joint torque

Joint method taken from the manufacturer's instructions
Instructions on hand for the joint type: torque-indicating bolt heads, a set torque or a resistance check, and when a joint is re-torqued or its bolt replaced.
No photo
Joint bolts checked to torque at the boltings
Each joint torque verified or its resistance measured per the manufacturer, re-torqued only where found loose, belleville washers at the specified flatness, any that moved noted for re-scan.
Plug-in stab contacts inspected
Plug-in stabs and contact fingers checked for pitting, spring tension and alignment, cleaned and re-seated where required.
No photo
Plug-in unit switches, fuses and lugs inspected
Where the run has plug-ins, each one opened dead, switch or breaker and load lugs free of heat marks, fuses matching the unit label, and the handle mechanism moving freely.
No photo

Run and supports

Hanger hardware checked tight along the run
Rods, clamps and fasteners checked with hand tools at every reachable section, beyond the quarterly's visual look, riser springs set to the manufacturer's mark.
Expansion and flexible fittings checked where fitted
Expansion fittings free to slide and flexible connections at transformers or gear intact, no cracked braid, binding or stressed joint.
No photo

Testing observed and recorded

NETA electrical tests witnessed and logged
Insulation-resistance and any contact-resistance results from the testing tech recorded along the run, out-of-range values flagged before re-energizing.
Ground path continuity measured along the run
Testing firm's ground continuity reading from the source to the far end set against the last outage, and any high-resistance joint cleaned and remade before closing up.

Return to service

Covers refitted and the run cleared before re-energizing
Joint covers back with every screw, any plug-in units stabbed and latched, the run clear of tools and temporary grounds, and each lock removed by the person who hung it.
Run re-energized and loads confirmed back with the owner
Feed closed in the planned order, voltage read under the energized-work procedure, owner confirms floors and loads restored, reworked joints flagged for the next scan.

What usually sends this back

The failures are almost always the evidence, not the work

Joint bolts checked only at the ground-level sections while the high joints that the quarterly scan flagged as warm get skipped again.
A belleville-washer joint torqued flat like a standard bolt, over-compressing the stack instead of setting it to the manufacturer's spec.
Covers reinstalled and the run re-energized before the testing tech's insulation readings across the run are recorded.
