Electrical Guides & Wiring

Upgrading from a 100-amp to 200-amp electrical panel typically costs $1,500-$4,000 including permits. Factors affecting price include your location, the condition of existing wiring, whether the meter base needs replacement, and utility company requirements. Always hire a licensed electrician for panel work.

Not always, but it's recommended. A Level 2 EV charger draws 30-50 amps. If your 100-amp panel has enough spare capacity, you may not need an upgrade. However, if you're already near capacity (common in homes with AC, electric dryer, and electric range), a 200-amp upgrade is necessary and future-proofs your home.

Rules vary by jurisdiction, but most areas allow homeowners to replace outlets, switches, light fixtures, and ceiling fans on existing circuits. You generally cannot do panel work, add new circuits, or wire new construction without a permit and inspection. Some states require a licensed electrician for all work. Always check local codes.

A Level 2 home EV charger installation costs $500-$2,500 total. The charger unit itself costs $300-$800, and electrician labor runs $200-$1,700 depending on panel distance, required upgrades, and permit fees. Federal tax credits can cover up to 30% of costs (up to $1,000).

Call an electrician for: panel upgrades, new circuit installation, aluminum wiring issues, any work requiring permits, GFCI troubleshooting beyond simple replacement, and any situation where you're unsure. DIY is appropriate for: replacing outlets/switches, installing light fixtures, and simple troubleshooting on de-energized circuits.
