Main Service Panel Upgrades: When a 100A-to-200A Upgrade Makes Sense

Oct 2

2 min read

A main service panel upgrade can be one of the most important electrical improvements on a property, especially when new loads such as EV charging, HVAC equipment, an ADU, solar, or battery storage are being added.

When a Panel Upgrade May Be Needed

Common reasons include limited breaker space, aging equipment, insufficient service capacity, equipment damage, or a project that adds significant new electrical load. A licensed electrician should evaluate the existing service, load calculations, utility requirements, and planned equipment before recommending a new service size.

Why 200A Service Is Common

Many modern homes and small commercial properties use 200A service because it provides more capacity for present and future loads. The correct service size still depends on the calculated demand and the utility-approved service configuration.
