New Main Electrical Panel Installation Cost Factors
Upgrading or replacing your home's main electrical panel can be a significant investment, with costs ranging from $1,200 to $4,500 or more depending on various factors. In this guide, we'll break down the key cost drivers for a new main electrical panel installation and provide practical pricing details to help you plan your budget.
Panel Size and Amperage
The size of your electrical panel and its amperage rating are two of the most significant factors influencing the cost of a new main electrical panel installation. A larger panel or non-standard installation increases both material and labor costs. For example, a 400-amp panel will cost more than a 100-amp panel, while a 200-amp panel falls in between.
- 100-amp panel: $1,200 - $2,000
- 200-amp panel: $1,500 - $2,500
- 400-amp panel: $2,000 - $3,500
Panel Type and Upgrade
The type of panel you need will also affect the cost of installation. A main panel, subpanel, or upgrade can have different prices depending on the complexity of the installation and any necessary upgrades. For example, a subpanel installation can be less expensive than a full main panel replacement.
- Subpanel installation: $1,000 - $2,000
- Main panel replacement: $1,500 - $3,500
Labor Time and Warranty

The labor time required for the installation, as well as the warranty offered by the electrician or contractor, will also impact the final cost. Experienced electricians or contractors may charge more for their services, but they often provide better quality work and longer warranties.
- General licensed electrician: $1,000 - $2,500
- Master licensed electrician: $1,500 - $3,500
Necessary Wiring or Permit Work
Any necessary wiring or permit work can add to the overall cost of the installation. This includes the cost of permits, inspections, and any modifications to the existing wiring or electrical system.
- Permit fees: $100 - $500
- Wiring modifications: $500 - $2,000

When planning a new main electrical panel installation, it's essential to consider the various cost factors, including panel size, amperage, panel type, labor time, and necessary wiring or permit work. By understanding these costs, you can budget accordingly and make informed decisions about your electrical panel upgrade or replacement.
