DA Form 7471-R: Transfer Switch Inspection Checklist PDF – If you work in US Army facilities maintenance, electrical contracting for DoD installations, or commissioning standby power systems on military bases, DA Form 7471-R is an essential tool. This official Transfer Switch Inspection Checklist (LRA) ensures automatic transfer switches (ATS) in emergency and standby power systems operate reliably during outages—critical for mission-critical C4ISR facilities, hospitals, command centers, and base operations across the United States.
In this complete 2026 guide, you’ll learn exactly what DA Form 7471-R is, why it matters, how to fill it out step-by-step, the full checklist items, and where to download the latest official fillable PDF.
What Is DA Form 7471-R?
DA Form 7471-R, titled TRANSFER SWITCH INSPECTION CHECKLIST (LRA), is a one-page, locally reproducible (LRA) form published by the U.S. Army in August 2002. It was developed by the U.S. Army Corps of Engineers (COE) for use with TM 5-694, Commissioning of Electrical Systems for Buildings.
The form standardizes visual, mechanical, electrical, and functional inspections of transfer switches that automatically shift power between normal utility service and emergency generators. It remains the current, authoritative checklist—no superseding version exists as of 2026.
Key sections include:
- Section A – Customer Data (plant/building, location, job number, equipment, circuit designation, date, test equipment, tested by)
- Section B – Equipment Data (manufacturer, style/S.O., voltage/current/switch ratings, enclosure type, frequency)
- Section C – Visual and Electrical/Mechanical Inspection
- Section D – Electrical Tests
- Functional test notes and condition codes (A = Acceptable, R = Needs Repair/Replacement/Adjustment, C = Corrected, NA = Not Applicable)
Why DA Form 7471-R Matters for US Army & DoD Facilities?
Transfer switches are the heart of Emergency Power Supply Systems (EPSS). A single failure can interrupt power to critical loads during outages. Regular use of DA Form 7471-R:
- Verifies proper installation and operation before system energization
- Establishes baseline test values for future maintenance
- Helps meet commissioning requirements in TM 5-694 and related standards (NFPA 110, NFPA 70B)
- Supports safety, reliability, and mission readiness on Army posts, camps, and stations nationwide
Facility managers, electricians, and contractors on Army installations use this checklist during new construction, renovations, annual maintenance, and commissioning of standby generators and UPS systems.
Complete Checklist Items on DA Form 7471-R
Section C (Visual & Mechanical Inspection) covers these key checkpoints:
- Exterior of equipment
- Completeness of assembly
- Indicating lights
- Switch for freedom of movement
- Electrical/mechanical interlocks
- Adjust timing settings
- Proper equipment grounding
- Contact resistance
- Tightness of bolted connections
- Insulation resistance
- Equipment identification, bracing, phase connections & color code
- Environmental classification
- Working clearance & anchorage
- Reference drawings
- Proper lubrication
- PT and control fuse size
Functional Tests (documented on the form):
- Switch transfers on loss of normal power at specified time delay
- Switch transfers back to normal power on return of service at specified time delay
- Auxiliary contacts operate correctly during normal and abnormal conditions
Section D records electrical test results (e.g., insulation resistance phase-to-phase and phase-to-ground in both normal and emergency positions).
All results are rated with the clear A/R/C/NA condition codes for quick acceptance or corrective action tracking.
How to Fill Out DA Form 7471-R? (Step-by-Step)
- Section A – Enter facility and job details, date (YYYYMMDD format), and inspector information.
- Section B – Record nameplate data from the transfer switch.
- Section C – Perform visual/mechanical inspection. Mark each checkpoint and add notes.
- Section D – Conduct and document electrical tests (use calibrated test equipment and record calibration dates).
- Functional Tests – Simulate power loss/return and verify timing and auxiliary contacts.
- Notes & Sign-Off – Document any deficiencies, corrections, or additional observations.
Pro Tip: Always follow manufacturer instructions and TM 5-694 procedures. Use calibrated test equipment and never megger-test electronics—follow OEM specs instead.
Best Practices for Transfer Switch Inspections on Army Bases
- Perform inspections during commissioning, after major maintenance, and per manufacturer/NFPA schedules.
- Combine with related forms: DA Form 7470-R (Utility & Generator Circuit Breaker), DA Form 7469-R (Backup Power System), and DA Form 7468-R (Engine Generator Set).
- Keep completed forms in facility maintenance records for trend analysis and compliance audits.
- Train personnel on proper safety procedures (lockout/tagout, PPE) before testing live equipment.
