Adding a Level 2 EV charger to a 1970s-era 100A service is generally not feasible or safe without an upgrade. The charger alone can demand 40-50 amps, which would overload your existing capacity when combined with other household loads like air conditioning. Furthermore, if your panel is the recalled Federal Pacific Electric brand, it poses a known fire hazard and must be replaced before adding any new major load. A full service upgrade to 200A is the standard, code-compliant solution for modern electric vehicle and heat pump compatibility.

Overhead mast service, while common, has specific vulnerabilities. The mast head or weatherhead can degrade, allowing moisture into your service entrance cables. The span of overhead lines is also exposed to tree contact and severe weather. You should visually inspect for any sagging lines, damaged conduit, or rust at the mast entry point. Ensuring the mast is properly secured and the service drop conductors are clear of tree branches is important preventative maintenance for this setup.

Preparation involves both protection and backup. For winter ice storms that can bring down lines, a permanently installed generator with an automatic transfer switch provides essential backup power, safely isolated from the grid. To guard against summer brownouts and the associated voltage fluctuations, ensure your air conditioner has a dedicated, properly sized circuit and consider hard-wired surge protection. These steps protect sensitive electronics from the low-voltage conditions common during peak AC season.

Flickering during storms is often a grid issue, and Louisville's high lightning risk means the LG&E system experiences frequent surges and faults. However, your home's internal protection is critical. These surges can bypass older panels and damage modern smart home devices, computers, and appliances. Installing a whole-house surge protector at your service entrance is a necessary defense. For persistent flickering, we should also check your meter base connections and grounding electrode system, as loose connections can amplify the problem.

For an emergency like that, we prioritize immediate dispatch. From our base near Cherokee Park, we use I-64 to access the entire Highlands area, typically arriving within 8 to 12 minutes. A burning smell at the panel requires shutting off the main breaker immediately to prevent a fire. Once on site, we can diagnose the fault, which is often a failed connection at the bus bars or a recalled Federal Pacific breaker, and make the area safe.

Your electrical system is now over 55 years old. NM-B Romex wiring from that era was sized for the loads of its time, which didn't include today's multiple high-draw appliances, computers, and entertainment systems. The dimming lights indicate voltage drop, a sign that your 100A service and branch circuits are being strained by 2026's energy demands. This is a common capacity issue in original Highlands homes, and a load calculation is the first step to determine if a service upgrade is needed.

Yes, the rolling hills and dense tree canopy common in this area directly impact electrical health. Overhead service lines running through heavy foliage are more susceptible to damage from falling limbs, causing intermittent faults. Furthermore, the rocky soil found on hillsides can make achieving a low-resistance ground for your grounding electrode system more challenging, which is vital for surge dissipation and safety. An inspection can verify your ground rods are properly installed and making sufficient contact with the earth.

In Louisville, any new circuit requires an electrical permit from Metro Planning & Design Services. As a master electrician, I handle this filing. All work must comply with the current adopted code, which is the NEC 2023, as enforced by the Kentucky Department of Housing, Buildings and Construction. Skipping permits risks fines and complicates home sales, as unpermitted work won't have the required inspections to verify it's safe and meets modern grounding, AFCI, and box-fill standards.
