How much does it cost to replace a fuse box professionally?

A professional fuse box replacement (panel change‑out) typically ranges from $1,500 to $14,000, with simpler projects often quoted around $1,000–$3,000. The biggest cost drivers are panel size (for example, upgrading 100A to 200A) and whether your service and wiring need updates to meet NEC 2023. Most panel replacements take about 4–8 hours once permits and planning are set, and final pricing is confirmed after an on‑site inspection. Our team frequently completes these upgrades for homes around Louisville and nearby communities.

Expect costs to rise when any of the following apply:

• Service‑entrance upgrade or meter/main work is required
• Significant wiring corrections or grounding/bonding upgrades are needed
• Panel relocation or limited working space adds labor
• Permit, utility coordination, or added features like whole‑home surge protection are included

Turn off power safely and avoid DIY; have a licensed electrician evaluate your existing panel, service size, and grounding before you set a budget.
