cost to install 100 amp sub panel

Installing a 100-amp sub panel is a great way to expand your home’s existing electrical capacity. Whether you're adding more power outlets, or wiring outbuildings and other large structures like a pool house or an outdoor kitchen, installing a sub panel will give you the capacity and flexibility that you need. But it’s important to know what you’re getting into before you start, as the cost to install a 100-amp sub panel can range anywhere from a few hundred dollars to several thousand.

The cost of installing a 100-amp sub panel will depend on the size of the panel itself, the circuit breakers you choose, and the amount of wiring needed to bring power to the new sub panel. For a small, single-load panel, you could be looking at as little as $500-$800 in costs. However, for larger scale panels with multiple circuits and lots of wiring, the costs could jump as high as $2,500 or more. If you plan to hire an electrician to do the work, you should also factor in the cost of labor.

It’s important to hire a licensed electrician to install a 100-amp sub panel, as doing so yourself could put your safety at risk. Not only are there certain codes and best practices to follow, but working with electricity can be dangerous if you don’t know what you’re doing. An experienced electrician will ensure that the installation is done correctly and safely, and could even provide additional value, such as suggesting ways to maximize the efficiency of your system or reduce the overall costs.
