That's a classic sign of insufficient capacity for a 29-year-old electrical system. Homes like yours in Callahan Oaks were wired with NM-B Romex for the appliance loads of the late 90s, not for today's high-draw devices. Your 150A service panel may be near its limit with modern refrigerators, computers, and entertainment systems all adding to the base load that didn't exist when the house was new. We often recommend a load calculation and panel upgrade to 200A to handle 2026 living standards safely.

Overhead service, or a mast service, is standard here but has specific vulnerabilities. The mast itself can be damaged by weather or falling limbs, and the service drop wires from the pole can degrade over decades. We frequently find loose connections at the weatherhead or where the wires land on the meter socket, which creates heat and arcing. During an inspection, we check the mast for structural integrity, the condition of the service conductors, and the tightness of all terminations to ensure a reliable connection from the utility.

For summer peaks, ensure your AC system is on a dedicated, properly sized circuit and consider a hard-wired surge protector to guard against grid fluctuations. For extended outages from storms, a professionally installed generator interlock kit and an outdoor power inlet is the safest solution. This allows you to backfeed essential circuits from a portable generator without the lethal danger of backfeeding into the utility lines, which is illegal and endangers line crews.

All major electrical work, especially a service upgrade, requires a permit and inspection from the Nassau County Building Department. The current Florida-adopted code is the NEC 2023, which mandates AFCI protection in most living areas and specific rules for emergency disconnects. As a state-licensed contractor through the Florida DBPR, I handle the entire permit process, ensuring the installation meets the latest safety standards. This protects you, as unpermitted work can void insurance and create serious liability during a home sale.

Potentially, yes. The sandy, well-drained soils common on Florida's coastal plain can have high electrical resistance, making it difficult to establish a proper ground. The NEC requires grounding electrodes to have a resistance of 25 ohms or less; we often need to drive multiple ground rods or use a concrete-encased electrode (Ufer ground) to achieve this in our area. Poor grounding compromises your surge protection and can create a shock hazard, so it's a key item we test during a service evaluation.

While FPU manages the grid, the surges themselves are typically caused by our region's high lightning activity. The utility grid can transmit these surges directly into your home. Modern electronics with sensitive microchips are especially vulnerable. A whole-house surge protector installed at your main service panel is the most effective defense, absorbing those massive voltage spikes before they reach your appliances. Point-of-use surge strips offer additional protection but cannot handle a direct lightning-induced surge on their own.

No, it is not safe to proceed. A Federal Pacific panel is a known fire hazard due to breakers that can fail to trip during an overload. Adding a 40-50 amp circuit for an EV charger to that panel creates a significant risk. Furthermore, a 150A service from 1997 often lacks the spare capacity for a charger and a modern heat pump simultaneously. The required solution is a full panel replacement with a new, code-compliant panel and an upgrade to 200A service, which we can then configure for your EV charger.

For an emergency like that, we dispatch immediately. From the Callahan Fairgrounds, our truck can be on US-301 and at your Callahan Oaks home in 5-8 minutes. A burning smell indicates an active fault, possibly at the main lugs or a failing breaker, which is a serious fire risk. Our first priority is to safely isolate the problem at the service entrance and prevent damage to your home's wiring before restoring power.
