Frequently Asked Questions
How much does an electrician charge per hour?
Electricians typically charge $75-150 per hour for standard work. Master electricians and emergency services may charge $150-250 per hour. Many jobs are quoted as flat rates rather than hourly.
Do I need a permit for electrical work?
Permits are typically required for new circuits, panel work, major installations, and any work that modifies your home's electrical system. Simple repairs and replacements usually don't require permits.
How much does an electrical panel upgrade cost?
Panel upgrades range from $1,500 for a 100-amp upgrade to $4,000+ for 200-amp service. Costs depend on existing wiring, accessibility, and local permit requirements.
How much does EV charger installation cost?
Level 2 EV charger installation typically costs $500-2,500 depending on amperage, distance from panel, and whether a panel upgrade is needed. This doesn't include the charger unit itself.
Can electrical companies customize this calculator?
