An interior subpanel upgrade is like adding a new, mini control center for electricity inside your home. Imagine you have a big main control center for your house's power, but sometimes you need more control in specific rooms or areas.

So, you install this smaller subpanel in a particular part of your home, like your garage or your basement. This subpanel helps manage the electricity for just that area. It's like having a separate switchboard for that part of your house.

This can be useful because it allows you to power more things in that area without overloading the main control center. It's like having an extra circuit breaker box for a specific part of your home, making it easier to use electricity safely and efficiently in that area.

An interior subpanel upgrade is all about improving the electricity distribution in your home.
