The overhead mast and weatherhead attached to your house are almost always the homeowner's responsibility. Oncor owns the service drop from the pole to your mast. A damaged mast can allow water ingress, leading to corrosion inside your panel and creating a serious shock or fire hazard. This repair requires a permit from the Wilmer Building Inspection Department and should be handled by a licensed electrician.

The Oncor grid serving Wilmer is prone to high surge risk, especially from our frequent North Texas lightning. While the utility manages large-scale fluctuations, these micro-surges regularly damage sensitive electronics. Installing a whole-house surge protector at your main panel is the most effective defense, creating a coordinated system to shunt destructive voltage spikes safely to ground.

Your home's electrical system is nearly 30 years old, installed in 1997. Original NM-B Romex wiring was designed for the appliance loads of that era, which are far less than what a modern heat pump or EV charger demands. This voltage drop under new heavy loads is a clear sign the system is reaching its capacity limits and should be evaluated for a potential service upgrade or dedicated circuit installation.

Absolutely. A panel replacement always requires a permit from the Wilmer Building Inspection Department and must be performed by an electrician licensed by the Texas Department of Licensing and Regulation. The work must fully comply with the current NEC 2023, which includes updated requirements for AFCI protection and surge protection. We handle all permitting and inspections to ensure the upgrade is documented and safe.

Yes, the dense, often clay-heavy soil in our flat prairie terrain can be a poor conductor. This challenges the effectiveness of your grounding electrode system, which is critical for safety and surge dissipation. We often need to drive grounding rods deeper or use multiple rods to achieve the low-resistance ground required by the NEC, ensuring fault currents have a proper path to earth.

A 150A panel from 1997 may have the physical space, but a load calculation is mandatory first. Modern Level 2 chargers require a dedicated 40-50 amp circuit, which is a significant new demand. Furthermore, we must check the panel brand; many homes from this period have recalled Federal Pacific panels, which are a known fire hazard and must be replaced before adding any major new load.

Start with a professional inspection to ensure your 150A service and panel are in sound health. For summer peaks, consider a hard-wired generator interlock kit to safely back up essential circuits. For winter, ensure outdoor receptacles and disconnect switches for heat pumps are accessible and protected. Whole-house surge protection is also critical year-round to guard against grid instability during severe weather.

For a burning smell, disconnect power to that circuit at your panel immediately. Our service trucks are often dispatched from the Wilmer City Hall area, and we use I-45 for a quick response, typically 5-8 minutes in Windmill Farms. This is an urgent safety issue, as the odor indicates overheating wires that could lead to a fire behind your walls.
