100 Amp Service in St. Charles, MO

Many older homes in St. Charles were built with electrical panels that simply weren't designed for modern demands - outdated 60 amp systems that trip breakers, struggle with everyday appliances, and fall short of today's safety standards. A 100 amp service upgrade is the right fix: it increases your home's electrical capacity, replaces aging equipment with up-to-date wiring, and brings your system into compliance with current local electrical codes. If your home is showing signs of an overloaded or undersized panel, addressing it at the source is always safer than working around it.
A 100 amp electrical service is appropriate for smaller residential properties or homes with moderate electrical loads, and represents a significant improvement over the outdated 60 amp panels still found in many older St. Charles properties. Missouri law requires that all electrical service upgrades be performed by a licensed electrician, meet current NEC and local code standards, and pass a formal post-upgrade inspection before the system is returned to service.
Upgrading to 100 amp service doesn't just add capacity - it replaces aging conductors and breakers with high-quality materials, reducing fire risk and giving your home a reliable electrical foundation for the years ahead.

The process starts with a thorough assessment of your existing panel and service entrance to identify what needs to be replaced or brought into code compliance. Your electrician removes the outdated service equipment, installs a new 100 amp-rated meter base and main panel, and reconnects all circuits using high-quality materials that meet current safety standards. Any wiring that doesn't comply with current local electrical codes is addressed during this phase so the finished system is both safe and fully up to code.
Boschert Electric Inc. manages every phase from start to finish, including coordinating with your utility provider and scheduling the required post-upgrade inspection. A 100 amp service upgrade delivers increased electrical capacity, enhanced safety through up-to-date wiring and equipment, and full compliance with current local codes - all confirmed before the project is closed out. Every circuit is tested after installation to verify proper operation throughout the upgraded system.
A comprehensive post-upgrade inspection is a built-in step of every service upgrade, not an afterthought. This inspection confirms that the installation meets all applicable standards and gives you the confidence that a licensed professional has reviewed the completed work from the panel to every connected circuit.
