Circuit Breaker Inspection Checklist

by Jacquie Fisher, from the Community

This checklist guides pre energization inspection of low voltage or medium voltage circuit breakers and switchboards. It covers verification against OEM drawings, labeling, bolt tightening and witness marking, functional handle checks, IP2X compliance, earthing straps, and cabinet cleanliness. Technicians record manufacturer and ratings, capture photos, and run continuity tests across phases and to earth with pass fail criteria for open and closed states. Protection and trip unit settings are documented, including IR, TR, Isd, Tsd, ramp and time settings, with evidence photos and markup of the protection study. PLC or RTU point to point checks validate auxiliary trip unit status and breaker open close signals. The workflow ends with onsite sign off and engineer review confirming compliance with design.

Switchboard Auxiliary Equipment Inspection
Use this inspection checklist to verify switchboard auxiliary equipment before and after energization. It covers surge diverters, 24V power supplies, Modbus splitters and cabling, and power meters. Tasks include confirming components against OEM drawings, checking labeling, performing continuity tests on fuses and circuits, validating Modbus point-to-point connections, and recording voltage and current readings at circuit breakers. Capture photos for evidence, mark up as-built drawings, and complete onsite and engineer sign-offs to confirm compliance with design specifications.

Circuit Breaker Maintenance Form
This circuit breaker maintenance form helps technicians and inspectors record critical checks for power distribution equipment. Use it to capture mechanism checks and timing tests, inspect gauges and pressure switches, reset counters, and review the control cubicle, door seals, and hardware. Document SF6 gas analysis including dew point, acidity, air content, purity, and pressure, or record oil levels and moisture for oil filled units. Check interlocks, housings, ductor test results, cable end boxes, CT condition and insulation resistance, terminations and earthing, and bushing condition and torque. Suitable for scheduled maintenance of HV circuit breakers in substations and industrial facilities.

PFC Energization Checklist
This PFC energization checklist guides electricians through safe commissioning of power factor correction equipment. It covers pre-energization inspections, verification against OEM drawings, isolation and lockout, compartment and connection checks, CT and controller validation, and capacitor details. Testing steps include earthing resistance, insulation resistance, and polarity. Post-energization procedures include a 6 point voltage test, phase rotation checks, controller configuration, CT and voltage verification, cooling fan function, and manual capacitor step testing. The template concludes with equipment records and onsite and engineering sign offs to confirm compliance with design specifications.

Switch Board Post Energisation Check Sheet
This switchboard post energisation check sheet guides electricians through pre-commissioning and commissioning checks to ensure safe energisation. It covers visual inspection for damage, presence and condition of escutcheons and covers, protection against access to live parts, confirmation of wiring, and readiness for energisation. Technicians record meter details, measure voltages at the SPD, main circuit breakers, RCDs and small breakers, verify phase rotation, and confirm WP meter and live indicators. The checklist includes RCD make and model and trip tests, circuit breaker settings, fault loop impedance and prospective short circuit values by phase, grading with upstream protection, sealing settings, and final lockout or tagout notes before energising final circuits.
