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
