Most people think of a home inspection as a single event — the general inspector who walks through before a purchase and generates a multi-page report. What general inspectors are not is licensed electricians. They flag obvious issues, but they’re not qualified to evaluate wiring types, panel brands, GFCI coverage, or the condition of a service entrance in any real depth.
A licensed electrician doing a dedicated electrical inspection is a different thing. We know what we’re looking at, we know what the current code requires versus what the older code allowed, and we can tell you what’s a genuine safety concern versus what’s simply outdated but not dangerous. Here’s what that inspection actually covers.
Who Needs an Electrical Inspection
There’s no single trigger — different situations bring different homeowners to this conversation:
Pre-purchase buyers — You’re buying a home built before 1980, the general inspector flagged “older wiring,” and you want to know what you’re actually getting into before closing. An electrical inspection at this stage gives you real information for negotiations and helps you budget for any work needed.
Insurance requirements — Some Connecticut carriers are requiring electrical inspections or documentation of panel condition before binding or renewing coverage, particularly for older homes with flagged panel brands (Federal Pacific, Zinsco) or knob-and-tube wiring.
Renovation planning — You’re adding a kitchen, finishing a basement, or building an addition. Before framing goes up or permits are pulled, you want to know the state of the existing electrical and what the renovation needs to account for.
Peace of mind after buying an older home — You closed on the house, the general inspection flagged some things, and now you’re living in it and want to understand what’s actually there. This is a very common reason we do inspections — and one of the most practical ones.
The Panel: First and Most Important
The electrical panel is the starting point of any inspection. We look at:
Brand — Federal Pacific Electric (Stab-Lok), Zinsco, and Pushmatic are all brands that warrant closer attention and immediate disclosure. FPE and Zinsco have documented breaker failure modes; Pushmatic panels are old enough that parts are unavailable and components may be worn beyond reliable function.
Age and condition — Panels don’t have a defined expiration date, but age matters. Signs of corrosion, moisture intrusion, burn marks, or melted plastic are immediate red flags. A panel from the 1970s with none of these signs may be functioning correctly; the same panel with scorch marks on the bus bar is a different story.
Capacity — Is the service size (100A, 200A) appropriate for the current electrical load? Homes that have added central AC, EV chargers, or additional circuits over the years without a panel upgrade may be running closer to capacity than is comfortable.
Double-tapping — Two wires on a single breaker terminal, when the breaker isn’t rated for it, is a code violation and a real concern. It means someone added circuits without properly expanding the panel. Common in homes where multiple owners have done electrical work over the decades.
Breaker condition — Are breakers tripping? Are any visibly damaged, corroded, or in the off position without explanation?
Wiring Type: What We Look For in the Attic and Basement
The wiring throughout the house tells a story about when the home was built and what’s been updated. We identify:
Knob-and-tube (K&T) — Pre-1940s wiring method. Two separate wires (hot and neutral) run on ceramic knobs and through ceramic tubes. No ground wire. No insulation jacket around the wire pair — they rely on air space for heat dissipation. K&T itself isn’t inherently dangerous if it’s in good condition and hasn’t been modified. The problems: it’s often been spliced improperly by homeowners or earlier contractors, insulation has been blown over it (which prevents the air cooling and can cause overheating), or it’s been connected to grounded outlets it doesn’t support.
Aluminum branch circuit wiring (1965–1973 risk period) — Aluminum wiring was used for branch circuits during a copper shortage from approximately 1965 to 1973. The problem isn’t the wire itself — it’s the connection points. Aluminum oxidizes at the terminations, which increases resistance and generates heat. Homes with aluminum wiring need all connections examined, and any CO/ALR or aluminum-rated devices confirmed at outlets and switches.
Cloth-insulated wiring — Common from the 1930s through the 1960s. The cloth jacket deteriorates over time, leaving wiring with cracked, brittle, or missing insulation. This is a fire risk from deterioration, not a wiring method problem per se.
Romex (NM cable) — Modern plastic-jacketed wire. Romex in good condition, properly installed, is not a concern. We check that it hasn’t been damaged, stapled improperly through studs, or connected to panels without appropriate strain relief.
GFCI and AFCI Compliance
GFCI (Ground Fault Circuit Interrupter) protection is required by current code in bathrooms, kitchens, garages, outdoors, unfinished basements, and near any water source. Older homes often have none of this — two-prong outlets in bathrooms, no GFCI in the garage, original kitchen outlets that have never been updated.
We note where GFCI protection is absent and whether it’s a code violation (for work done without permits) or simply a pre-code installation that hasn’t been brought up to current standards. Missing GFCI protection near water is a genuine safety concern; we flag it clearly.
AFCI (Arc Fault Circuit Interrupter) protection is required for bedrooms under current code and increasingly for living areas. AFCI breakers detect arcing faults — the kind that cause wiring fires from damaged or pinched wires — before they ignite something. Most older homes have none. We note absence; installation is typically a per-circuit cost if you want to bring specific areas into compliance.
Grounding: Two-Prong vs. Three-Prong
Two-prong outlets in an older home mean the circuits are ungrounded. Three-prong outlets on an ungrounded circuit — which many homeowners and previous electricians have installed as a cosmetic update — are more dangerous than they look, because they create the expectation of grounding where none exists.
We test outlets for proper grounding using a receptacle tester, note which circuits are ungrounded, and explain the options: running a ground wire to the panel (ideal but labor-intensive), GFCI protection as an acceptable code substitute, or leaving two-prong outlets where they are.
Service Entrance and Meter
The service entrance — the point where utility power enters your home — gets checked for:
- Weatherproofing — Is the mast sealed? Is there moisture getting into the meter base?
- Mast condition — Bent, rusted, or undersized masts are flagged. A leaning mast is a structural concern, not just an aesthetic one.
- Service entrance cable condition — Aluminum service entrance cable (standard on almost all residential services) should show no signs of corrosion at the lugs. We look at the meter base connections on both sides.
- Service size adequacy — Is 100A service still adequate for this home’s current use? We flag when service appears undersized for the load.
Outlets and Switches
We check a representative sample of outlets and switches throughout the home:
- Polarity — Hot and neutral reversed at an outlet is a wiring error that can damage sensitive electronics and create a shock hazard
- Physical damage — Cracked, loose, or missing cover plates; outlets that don’t hold plugs securely
- Loose connections — Outlets that move or feel unstable in the box
What We Note vs. What We Flag as Urgent
Not everything we find requires immediate action. Our written report distinguishes between:
Urgent/safety concerns — Things that represent a present or likely near-term hazard: burn marks in the panel, non-functional GFCI near water, live wiring improperly terminated, Federal Pacific panel with signs of heat damage.
Code deficiencies — Items that don’t meet current code but were acceptable under the code in effect when the home was built. These may be required to be corrected if permits are pulled for other work.
Informational notes — Things you should know about the home’s electrical condition that don’t require immediate action but inform future planning decisions.
We don’t use inspection reports to generate repair sales. The inspection is standalone, priced as such, and the report is yours to use however you’d like — for negotiations, insurance purposes, or your own planning.
