What Gets Assessed
What Our Electrical Panel Inspection Covers
A NorTech panel inspection goes far beyond a visual glance — our certified electricians open the panel, assess every component, and document findings with specific corrections recommended for each defect identified.
Main Breaker & Service Entrance
Condition of the main breaker, service entrance wiring, and meter connection — including signs of heat damage or corrosion at the point of entry.
Individual Circuit Breakers
Operation, condition, and amperage rating of each breaker — identifying any that are failing, double-tapped, or improperly sized for their circuit.
Wiring Connections & Bus Bars
Neutral and ground bar connections, bus bar condition, wire gauge compatibility, and signs of overheating, arcing, or loose terminations.
Grounding & Bonding
Proper separation of neutral and ground bars, grounding electrode conductors, and bonding of metal components per current electrical code.
Panel Labeling & Organization
Accuracy and completeness of circuit labeling — unlabeled or mislabeled circuits are identified and corrected during the same visit.
Available Capacity
Assessment of remaining breaker slots and total amperage load — critical for homeowners planning to add EV chargers, HVAC systems, or significant new electrical loads.
What We Find & Fix
Common Panel Defects Found During Inspection
These are the most frequently identified safety issues in residential electrical panels — all correctable without replacing the entire panel.
Double-Taps
Two wires connected to a single breaker terminal rated for one — a loose connection that can arc and cause a fire. Corrected with a tandem breaker or separate circuit.
Oversized Breakers
A breaker rated higher than the wire gauge it protects — allowing the wire to overheat before the breaker trips. Corrected by replacing with the proper amperage breaker.
Missing Knockouts
Openings in the panel enclosure that expose live components and introduce moisture and pest entry points — corrected with snap-in knockout fillers.
Unlabeled Circuits
Circuits with no or inaccurate labels create hazards during emergencies and electrical work — corrected with a full circuit identification and labeling pass during the visit.
Neutral-Ground Mixing
Neutrals and grounds sharing the same bar in subpanels where they must be separated — a code violation corrected by adding a separate bar and rerouting conductors.
Signs of Overheating
Discoloration, melting, or a burning smell inside the panel indicates a serious past fault — these components are flagged and replaced immediately.
Time for an Inspection?
Signs Your Electrical Panel Needs Professional Inspection
- You’re buying or selling a home. A general home inspection gives only a cursory look at the panel. A dedicated electrical panel inspection documents every defect, giving buyers negotiating leverage and giving sellers the opportunity to address issues before listing. Many realtors and lenders now request electrical inspection documentation separately.
- Your panel is 25 or more years old. Older panels — particularly those from the 1970s through 1990s — may contain breakers that no longer trip reliably, aluminum branch wiring connections that need attention, or panel brands associated with known reliability concerns. Age alone warrants a professional assessment.
- You’re planning a significant electrical addition. Before adding an EV charger, upgrading HVAC, finishing a basement, or taking on any major new electrical load, a panel capacity assessment confirms whether your existing service can accommodate the demand — or whether a panel upgrade needs to come first.
- You notice burning smell, flickering lights, or whole-home tripping. These symptoms can point to a panel-level fault — a failing main breaker, a loose bus bar connection, or an overloaded service — rather than an isolated circuit problem. A panel inspection pinpoints whether the source is at the panel.
- Your panel has never been professionally inspected. Most homeowners have no idea when their panel was last opened and assessed. If you’ve owned the home for more than 10 years without an inspection — or inherited it from a previous owner — a panel audit is one of the highest-value electrical services available.
Transparent Pricing
What Affects the Cost of an Electrical Panel Inspection?
Panel inspection pricing is straightforward — here’s what determines the scope and cost of your service call.
Every job starts with a full written estimate. You receive complete pricing before any work begins — no surprises.
“Had a panel inspection before listing our home. NorTech found four double-taps and two mislabeled circuits, fixed everything on the spot, and provided a written report. Our realtor said it was exactly what buyers want to see.”
David R.“Bought an older home and had NorTech inspect the panel before moving in. They found an oversized breaker on the laundry circuit and a loose neutral that could have been a real problem. Both corrected same visit.”
Tanya B.“Needed a capacity assessment before adding an EV charger. NorTech confirmed I had room, installed the charger same day, and added surge protection while they were in the panel. Efficient visit from start to finish.”
Greg H.“Our panel was completely unlabeled — the previous owners never mapped it. NorTech went circuit by circuit, identified everything, and labeled the panel properly. Should have had this done years ago.”
Camille O.“Inspection flagged signs of overheating on two breakers I never would have caught. Both replaced immediately. The written report gave me documentation that the panel was in safe condition. Worth every dollar.”
Frank S.“Had the inspection done as part of renovation planning. NorTech confirmed enough capacity for everything we wanted to add and gave us a clear picture of what was safe to proceed with. Very thorough and professional.”
Maria & Luis E.Common Questions
Frequently Asked Questions — Electrical Panel Inspection & Minor Upgrades
What does an electrical panel inspection include?
A NorTech electrical panel inspection includes a visual and functional assessment of the panel enclosure, main breaker condition, individual circuit breakers, wiring connections, bus bars, neutral and ground bars, grounding, panel labeling, and identification of safety issues such as double-taps, oversized breakers, and signs of overheating or moisture damage.
When should I get an electrical panel inspection?
An electrical panel inspection is recommended when buying or selling a home, when the panel is 25 or more years old, after a power surge or lightning strike, when adding significant new electrical load, if circuit breakers are tripping frequently, or if you notice signs of burning, buzzing, or flickering throughout the home.
What is a double-tap and why is it a problem?
A double-tap occurs when two circuit wires are connected to a single breaker terminal rated for one wire. This creates a loose connection that can arc, overheat, and cause a fire. Double-taps are one of the most common electrical defects found during home inspections and are corrected by installing a tandem breaker or running the second wire to its own breaker.
How long does an electrical panel inspection take?
A thorough electrical panel inspection takes approximately one to two hours. If minor corrections such as double-tap repairs, breaker replacements, or labeling are performed during the same visit, the total time may extend to two to three hours depending on the scope of work identified.
How much does an electrical panel inspection cost?
Electrical panel inspection cost depends on panel size, accessibility, and the scope of any corrections performed during the visit. NorTech provides a written estimate before any work begins. Corrections identified during the inspection are quoted separately so you can approve them before they are performed.
What is the difference between a panel inspection and a panel upgrade?
A panel inspection is a diagnostic service — our electricians assess the condition and safety of your existing panel without replacing it. A panel upgrade replaces the entire panel with a higher-amperage service. NorTech performs panel inspections and minor corrections. If a full panel replacement is required, we will advise and refer you to the appropriate service.
Should I get a panel inspection before buying a home?
Yes. A general home inspection typically includes only a cursory look at the electrical panel. A dedicated electrical panel inspection by a certified electrician provides a far more detailed assessment — including breaker condition, wiring quality, safety defects, and remaining capacity. This information is critical for negotiating repairs or understanding what upgrades a home will need.
What are minor panel upgrades?
Minor panel upgrades are corrections and improvements made within the existing panel without replacing it. Common examples include double-tap corrections, breaker replacements, AFCI and GFCI breaker upgrades, proper labeling of all circuits, grounding corrections, and addition of a whole-home surge protector.
