Signs to document
- panel is damaged, corroded, warm, or unreliable
- planned loads exceed documented capacity
- replacement parts or configuration create concern
- service or meter work is proposed
- circuits and labels do not match the building
Electrical panels
A decision guide for panel replacement, service changes, added capacity, obsolete equipment concerns, labeling, grounding, utility coordination, and inspection.
List the reason for the upgrade, existing service and panel information, planned loads, known damage, circuit problems, and utility equipment. A panel proposal should explain whether the service, meter, feeders, grounding, circuits, or building finishes also change.
Compare the written scope
Ask what test isolated the fault and what evidence supports the recommendation. A symptom alone does not identify every underlying cause.
Confirm labor, materials, model numbers, permits, access, disposal, cleanup, startup, and any walls, floors, landscaping, or finishes that another trade must restore.
Request invoices, warranty terms, permit or inspection records when applicable, equipment settings, test results, and clear instructions for operation and maintenance.
Service-specific scope
The scope should identify service rating, panel and main equipment, load basis, utility coordination, meter and feeders, grounding and bonding, circuit extensions, protection, permits, outage, wall repair, labeling, testing, and closeout.
Common questions
Not always. Capacity depends on loads, service rating, panel configuration, and approved options. Ask for the evaluation that supports the proposed work.
Record utility and permit coordination, shutdown timing, affected equipment, temporary needs, occupant communication, and who verifies safe restoration of service.
Labels should identify the actual areas and equipment served. Keep the permit and inspection record, equipment information, photographs, and test results with the directory.
