Electrical Panel Inspection Checklist: What to Photograph, Note, and Call Out
If you want fewer call-backs and fewer disputes, get your electrical panel documentation tight.
Clients rarely remember what you said about the panel. But they will remember:
- Whether the panel is “safe”
- Whether an electrician needs to be called
- Whether they can negotiate repairs
This checklist is designed for real-world home inspections: what to photograph, what to note, what to avoid touching, and how to write it clearly.
Important
Only open and inspect what your SOP allows and what you can do safely. If a panel is unsafe to open (arcing, buzzing, heat, water, corrosion), document the limitation and recommend electrician evaluation.
First: The Minimum Photo Set (Defensible Baseline)
Take these even if the panel looks “fine”:
- Panel location/context (where it is in the home)
- Panel cover closed (shows condition and accessibility)
- Panel cover open (overall interior view)
- Panel label/data (brand, model if visible, service rating/amp)
- Main disconnect (if present)
- Panel schedule / legend (even if messy)
If there is a subpanel, repeat the set.
Key Takeaway
A “panel close-up of one defect” with no overall photo is a common documentation failure. Always get at least one full open-panel shot.
Panel Identification Checklist (Write These Down)
- Manufacturer/brand (e.g., Square D, Siemens, GE, Eaton)
- Panel type: main service panel vs subpanel
- Service size/amp rating (from label or main breaker)
- Approximate age (if label indicates) or note “age unknown”
- Location (garage, basement, exterior, closet)
Accessibility & Safety Checklist
- Working clearance present (typically ~30" wide x 36" deep x 6'6" high per common standards)
- No storage blocking access
- Panel cover intact, secured, no missing knockouts
- No evidence of water intrusion, rust, or active corrosion
- No scorch marks, melted components, buzzing, or heat
If blocked:
- Photograph the obstruction
- Note limitation (“panel not fully accessible for inspection”)
What to Look For Inside the Panel (Common Defects)
1) Double taps / multiple conductors under one lug
- Not always prohibited (some lugs are rated for 2 conductors), but often improper.
Document:
- Which breaker/lug (if possible)
- Photo close-up
2) Neutrals and grounds not properly separated (subpanels)
In subpanels, neutrals should typically be isolated from grounds.
Signs:
- Neutral and ground on same bar with bonding screw/strap present
3) Missing bushings/strain relief at knockouts
- Sharp edges can damage conductors
4) Open knockouts
- Allows pests/debris; safety issue
5) Corrosion / moisture
- Rust on can, water staining, white/green corrosion on lugs
6) Overheating evidence
- Discolored insulation, melted breaker, scorch marks
7) Improper breaker sizes / conductor sizing concerns
- Example: oversized breaker on smaller gauge conductor (when identifiable)
8) Aluminum wiring and terminations (if present)
- Look for AL conductors and note proper terminations/antioxidant where visible.
9) Panel brand concerns (market-dependent)
If you encounter a panel type with known concerns in your market, document brand/model and recommend electrician evaluation when defects are present.
Note
Don’t turn brand recognition into a blanket condemnation. Keep it evidence-based: brand/model + observed defects + recommendation.
Service Entrance / Main Disconnect (If Visible)
- Service entrance conductors condition (visual)
- Drip loop and mast (if exterior)
- Main disconnect labeling and function (visual only unless tested)
GFCI/AFCI Notes (Panel-Related)
- Note presence of AFCI/GFCI breakers if visible
- If circuits that typically require protection lack it, document as a safety upgrade recommendation (based on your SOP and local standards)
Report Language Templates
Template: blocked access
“Electrical panel was not fully accessible due to stored items/obstructions. A complete inspection was limited. Recommend clearing access and having a qualified electrician evaluate the panel as needed.”
Template: corrosion/moisture
“Corrosion/moisture staining observed inside the electrical panel. Moisture can lead to unsafe conditions and equipment failure. Recommend evaluation and repairs by a licensed electrician.”
Template: double taps
“Multiple conductors observed under a single breaker/lug (double tapping) where not clearly rated for multiple conductors. Recommend evaluation/correction by a licensed electrician.”
Template: overheating
“Evidence of overheating observed at breaker/conductor connection(s) (discoloration/heat damage). This is a safety concern. Recommend immediate evaluation by a licensed electrician.”
Template: subpanel bonding issue
“Subpanel appears to have neutral and ground bonding concerns (neutrals/grounds not properly isolated). Recommend evaluation and correction by a licensed electrician.”
Important
Avoid statements like “panel is unsafe” unless you have specific observed evidence. Instead: “safety concern due to ____; recommend electrician evaluation.”
What NOT to Do (Scope + Liability)
- Don’t remove dead-front covers if your SOP doesn’t allow it
- Don’t touch service conductors
- Don’t manipulate breakers repeatedly
- Don’t move insulation/objects inside the panel
- If you see active arcing, heat, or water: stop and document
Where ReportWalk Helps
Electrical findings are where clear language matters most. ReportWalk helps you dictate:
- What you saw (observable)
- Why it matters (risk)
- What to do next (recommendation)
And pair it with the exact panel photos that make your report defensible.
Quick Field Checklist (Copy/Paste)
Photos:
- Panel location/context
- Cover closed
- Cover open (full)
- Label/amp rating
- Main disconnect
- Panel schedule
Visual checks:
- Clearance/access OK (or limitation documented)
- Cover secured, no open knockouts
- No moisture/corrosion
- No overheating evidence
- No double taps (or documented)
- Subpanel neutral/ground separation (if applicable)
Report:
- Location + service size + brand
- Defects with photos + clear electrician recommendation
