Licensed Electrician Serving
Boone County, Indiana

Homes built before the 1970s in Lebanon, Thorntown, and Jamestown frequently have outdated wiring systems, including knob-and-tube wiring, aluminum branch circuit wiring, and undersized electrical panels rated at 60 or 100 amps. These systems were designed for far fewer demands than a modern household places on them.

Common symptoms include frequent breaker tripping, flickering lights when appliances cycle on, warm or discolored outlet covers, and two-prong outlets that cannot accept grounded plugs. If your home was built before 1980 and has never had an electrical update, a professional inspection is strongly recommended.

An electrical panel upgrade is recommended when your home has a 100-amp or smaller panel that cannot support modern loads, when breakers trip regularly under normal household use, when you are adding high-draw equipment such as an EV charger or new HVAC system, or when your panel is a Federal Pacific or Zinsco brand with documented safety defects.

In Boone County, panel upgrades require a permit and a post-work inspection. Zimmerman Electric handles the full process: assessment, permitting, utility coordination, installation, and final inspection.

Boone County, particularly the Zionsville and Whitestown corridors, has a higher-than-average rate of electric vehicle adoption. Higher household incomes, newer garage-equipped homes, and proximity to Indianapolis all contribute. Most Level 2 EV chargers require a dedicated 40-amp or 50-amp 240V circuit. Homes with 200-amp panels can typically accommodate this without issue, but homes with 100-amp panels may need a panel upgrade first.

Zimmerman Electric assesses your panel capacity, installs the dedicated circuit, mounts and connects the charger, and handles the required permit. We install all major brands including Tesla Wall Connector, ChargePoint, JuiceBox, and Emporia.

Several electrical upgrades directly increase a Boone County home's market value and appeal to buyers. A 200-amp panel upgrade is one of the most impactful, as home inspectors flag outdated or undersized panels in nearly every pre-1990 home sale.

Other value-adding upgrades include whole-house surge protection, EV charger installation (especially with an installed 240V outlet in the garage), updated GFCI and AFCI protection throughout the home, modern recessed lighting, and replacing any knob-and-tube or aluminum wiring. These improvements also reduce insurance premiums and eliminate common deal-breakers during the home inspection process.

Flickering lights are one of the most commonly reported electrical symptoms in Boone County homes, especially in older Lebanon and Thorntown properties. Causes include loose wiring connections, an overloaded circuit shared with a large appliance, a failing breaker, or an undersized panel that cannot distribute power cleanly across all circuits.

Occasional, brief flickering when a large motor starts (such as an HVAC compressor) may be normal. Persistent or worsening flickering warrants a professional inspection, as it can indicate a loose connection that generates heat and creates fire risk.

Yes. Most electrical work in Boone County requires a permit. This includes electrical panel replacements, new circuit installations, EV charger installation, significant rewiring, and service upgrades. Permits are issued by the Boone County building authority and are followed by a mandatory inspection.

Unpermitted electrical work creates serious liability: it can void homeowner's insurance, complicate home sales, and leave unsafe conditions undetected. Zimmerman Electric pulls permits and schedules inspections for every project that requires them.
