Everything you need to know before hiring a electrician.
Residential electricians handle home wiring, panel upgrades, and outlet installation. Commercial electricians work on business facilities. Master electricians have the highest license level and can pull permits and supervise work. For most home projects, a licensed journeyman or master electrician is appropriate.
A 200-amp electrical panel upgrade typically costs $1,500–$3,000 installed, including materials and permit. Older homes upgrading from 100-amp or 60-amp service may also need new wiring to the meter, which can add $500–$2,000. Prices vary by region and panel brand.
Most electrical work beyond simple fixture replacements requires a permit. This includes panel upgrades, new circuits, rewiring, EV charger installation, and generator connections. A licensed electrician will pull the permit and schedule inspections. Unpermitted work can cause issues when selling your home.

Find a ContractorSigns include frequently tripping breakers, flickering lights, a panel that feels warm, a Federal Pacific or Zinsco panel (known safety hazards), fuses instead of breakers, or a home with major additions that has outgrown its original service capacity. A licensed electrician can assess your panel.
GFCI (Ground Fault Circuit Interrupter) outlets detect ground faults and shut off power instantly to prevent electrocution. They are required by code in bathrooms, kitchens near sinks, garages, outdoor outlets, basements, and near pools or hot tubs. They have a test and reset button on the outlet face.
A typical 1,500–2,500 sq ft home takes 3–7 days to rewire. The timeline depends on home size, construction type (wood frame vs. plaster walls), the number of circuits, and whether the home is occupied during work. Rewiring is recommended for homes over 40 years old with original wiring.
Installing a Level 2 EV charger (240V) involves working with high-voltage wiring and typically requires a permit. It is not a DIY project for most homeowners. A licensed electrician will install a dedicated 240V circuit, mount the charger, and ensure compliance with electrical code.
Fuse boxes use one-time-use fuses that must be replaced when blown. Breaker panels use resettable circuit breakers. Modern building codes require breaker panels. If your home has a fuse box, upgrading to a modern breaker panel is recommended for safety, insurance compliance, and modern electrical capacity.
Verify an electrician's state license on your state's contractor licensing board website. Ask for proof of liability insurance and workers' compensation. Check reviews on platforms like Google and the BBB. Get at least two written quotes that detail scope, materials, and permit fees.
Common causes include overloaded circuits (too many devices on one circuit), a short circuit (damaged wiring), a ground fault (wiring contacting ground), or a faulty breaker. Occasional tripping is normal; frequent tripping of the same breaker indicates a wiring problem requiring a licensed electrician.
