Electrical service and panel before energization checklist

A pre-energization electrical service and panel checklist for approved equipment, service conductors and raceways, meter and disconnect, panel mounting and clearances, feeders, neutral and grounding separation, grounding electrode and bonding, breaker compatibility, conductor protection, labeling, unused openings, surge and protective devices, utility release, permits, and photographic evidence before power is restored.

Installed service, meter, disconnect, panel, and breaker equipment match approvals

Critical item

Ratings, environmental use, listing, available fault-current suitability, and equipment combinations should match the approved design.

Equipment mounting, working space, access, weather protection, and structural support are complete

Critical item

Service equipment should be secure, accessible, and protected without storage or building conflicts.

Service and feeder conductors, raceways, mast, weatherhead, penetrations, and mechanical protection are complete

Critical item

Conductors should follow the approved route and remain protected, supported, sealed, and correctly terminated.

Grounding electrode, bonding, neutral isolation, and service disconnect relationships are documented

Critical item

Grounded and grounding conductors should be configured according to service and downstream equipment roles.

Breakers, conductors, torque or verification records, protective devices, and enclosure openings are complete

Critical item

Components should be listed for the equipment, sized to conductors and loads, and leave no exposed openings.

Permit approval, utility authorization, labels, photographs, and energization plan are complete

Critical item

Power should not be restored until required parties release the installation.

Use after installation but before permanent energization or utility reconnection. This is a document and visual readiness review only; qualified electricians and inspectors must perform internal and energized verification. Do not remove electrical covers, operate unapproved equipment, test energized conductors, backfeed circuits, or bypass interlocks. Service, panel, EV, generator, solar, and battery work must be performed and inspected by qualified persons where required.
