Flat coastal plain terrain often has high soil moisture, which can accelerate corrosion on underground grounding electrodes like ground rods. While good moisture improves conductivity, it also requires more frequent inspections of the grounding electrode system to ensure it hasn't deteriorated. A compromised ground can lead to erratic appliance operation and reduce protection from surges.

Homes in North San Juan built around 1999 used NM-B Romex, which is code-compliant but often lacks capacity for today's simultaneous loads. Your 150A service panel, once generous, now powers more electronics, HVAC, and high-draw appliances than originally intended. This can cause voltage drops, leading to dimming lights. A load calculation can determine if your current service is sufficient for modern usage.

Summer AC peaks strain the grid, while winter ice can bring down lines. For brownouts, a whole-house surge protector is critical to guard against low-voltage damage. For extended outages, a properly installed and permitted generator with a transfer switch is the safest solution. Ensure your main panel and its grounding system are in good health to support either backup system reliably.

Any panel replacement or service upgrade requires a permit from San Juan Building Inspections and a final inspection. As a Master Electrician licensed by the Texas Department of Licensing and Regulation, I handle this process, ensuring the installation meets NEC 2023 code. This includes proper AFCI breaker requirements, load calculations, and grounding. Skipping permits risks a failed sale, insurance issues, and safety hazards.

A Federal Pacific panel must be replaced before any major upgrade. These panels have a known failure risk and are not listed for safe operation. Even with a new 200A panel, a 1999-era 150A service may struggle to support a Level 2 EV charger and a modern heat pump simultaneously. A full service evaluation and likely an upgrade to 200A are necessary for safe, code-compliant capacity.

Repairing an overhead mast involves two steps. First, AEP Texas must disconnect power at the pole. Then, a licensed electrician can replace the mast, weatherhead, and conduit to meet current NEC and utility standards. After the repair, we coordinate with the utility for reconnection and ensure the city's Building Inspections Department signs off on the work. This process protects your home's connection to the grid.

The AEP Texas grid in our region has a high surge risk, especially from frequent lightning on the coastal plain. Utility-side fluctuations can easily damage sensitive electronics. While the utility manages the main grid, protecting your home requires a professionally installed whole-house surge protector at the service panel. This device, combined with point-of-use protectors, creates a layered defense for your investment.

For an active burning smell at the panel, call 911 immediately to dispatch San Juan Fire-Rescue, as this indicates a potential fire. Simultaneously, a Master Electrician can be en route from the San Juan Municipal Park area, typically arriving in 8-12 minutes via US-83. Do not attempt to reset breakers or operate the panel yourself while you wait for professionals to assess the hazard.
