Annual Whole-Home Electrical Inspection
Purpose
Define a structured annual electrical inspection for residential service-contract customers. The visit isn't about fixing things - it's about catching the issues that will become emergencies. A loose neutral found in October prevents the New-Year's-Eve nuisance-trips call. A flagged recalled panel becomes a documented liability ladder the customer should walk down before insurance forces them to.
Scope
Applies to:
- Residential service-contract customers
- Real-estate-transaction pre-listing inspections (limited adjustments)
- Insurance-required inspections (often required for older homes)
Excludes new-construction sign-off (separate scope) and panel replacements (those are the result of an inspection, not the inspection itself).
Responsibilities
- Dispatcher schedules at customer's anniversary month; confirms whole-home access
- Lead electrician walks the home + documents findings with photos
- Customer receives a written report with prioritized findings before tech leaves
Procedure
- Customer briefing. "60 - 90 minutes. I'll inspect every panel, every outlet sample, the meter, and document anything that needs attention."
- Exterior survey. Service drop / lateral, weatherhead, meter mast, condition of the service-entrance cable. Look for tree contact, frayed insulation, missing meter seal.
- Meter base. Look for burn marks, water staining, loose mounting.
- Main panel. Open the deadfront. Photograph the panel front + interior before any work.
- Brand check: Federal Pacific Stab-Lok, Zinsco, recalled Square D - document model + serial; recommend replacement.
- Torque check: spot-check torque on main lugs + bus connections (with panel de-energized at the meter where possible). Loose terminations cause heating.
- Visual scan: discoloration around any breaker = chronic overload OR loose connection. Pull and inspect.
- Neutral bus check: corroded or loose ground/neutral terminations cause "neutral hunting" lights-flickering issues.
- Bonding: verify main bonding jumper is intact, sized correctly per the system size.
- Sub-panels (if present). Same inspection as main panel. Verify they're 4-wire fed (separate ground + neutral) - a 3-wire sub-panel feed in a modern home is a code violation that's worth quoting.
- GFCI / AFCI testing. TEST each GFCI/AFCI outlet + breaker in the home. Replace any that fail.
- Receptacle sample. Use a circuit tester on at least 1 outlet per room. Note any open grounds, reversed polarity, or wiring errors.
- Smoke + CO detector verification. Press test button on each. Replace batteries on any battery-only units; flag any > 10 years old for replacement.
- Visible wiring. Walk the basement / crawl / attic with a light. Look for:
- Knob-and-tube remnants (pre-1950 homes)
- Aluminum branch wiring (1965 - 1973) - flag for COPALUM remediation quote
- Missing or damaged staples
- Junction boxes without covers
- Wire splices outside boxes (a fire hazard + code violation)
- Generator transfer / interlock (if present). Verify operable per generator-install SOP.
- Surge protector (if present). Verify indicator shows "Protected." Replace if event-triggered.
- Customer walk-through. Review the report. Urgent items quoted in person. Long-term items (panel age, aluminum branch wiring) documented for the customer's planning.
Acceptance Criteria
- Every panel inspected with photos
- GFCI / AFCI devices tested + documented
- Receptacle sample completed with results
- Smoke / CO detectors tested + ages noted
- Written report delivered to customer
- Urgent items quoted in person
Federal Pacific Stab-Lok and Zinsco panels are documented fire hazards. They don't trip reliably under overload conditions, leading to overheating and fires. NEVER service a known-recalled panel without recommending replacement on the customer's file. If a fire occurs after you serviced one and didn't flag it, the liability is on your shop.
