About Electricians
Electrical work is one of the few home improvement categories where DIY is genuinely dangerous — and in most jurisdictions, illegal for anything beyond basic fixture replacement. Licensed electricians hold state or local licenses that require passing examinations on the National Electrical Code, and their work must be inspected by local building departments for most projects.
Common residential electrical projects include panel upgrades (especially in older homes with 100-amp service or outdated breaker types), EV charger installation, circuit additions for kitchen appliances or home offices, whole-home rewiring, generator transfer switch installation, and outdoor lighting. Each of these requires permits and inspection in virtually every US jurisdiction.
Frequently Asked Questions
What electrical work requires a permit?
Almost everything beyond replacing existing fixtures and outlets. Panel work, new circuits, new wiring, EV charger installation, generator hookups, and outdoor electrical work all require permits in most jurisdictions. An electrician who offers to skip permits is a significant red flag.
How do I know if my electrical panel needs upgrading?
Signs include frequently tripping breakers, lights flickering when appliances run, outlets that feel warm, a 100-amp panel in a home with modern appliance loads, or Federal Pacific/Zinsco breakers (documented safety issues). A licensed electrician can assess your panel's adequacy.
What's the cost of a panel upgrade?
Upgrading from 100A to 200A service typically runs $1,800-$3,500 including permit and inspection. Cost varies by region and the complexity of the existing installation. In some older homes, additional service entrance work adds cost.
How long does electrical work take?
A single circuit addition takes 2-4 hours. A panel upgrade takes a full day. Whole-home rewiring takes several days to a week depending on home size and accessibility. Permit inspection may add a day or two to the schedule.
