Common Questions
What does an electrical inspection from an engineering firm involve?
For Patterson & Dewar, an electrical inspection is a detailed engineering evaluation. It goes beyond basic code checks to assess the integrity, capacity, and safety of power delivery systems. Our engineers analyze components like substations or distribution lines for potential failures, efficiency issues, or needed upgrades, providing a comprehensive report grounded in utility-grade standards. This is particularly valuable for complex properties or infrastructure connected to the main grid.
As an Addison resident, can you help with frequent arc fault breaker trips?
Absolutely. While we don't perform residential repairs, our electrical inspection service can be crucial for diagnosing persistent issues like nuisance tripping. We can evaluate if the problem stems from the property's internal wiring, an overloaded circuit design, or potentially from external grid interactions or surge events common in our area. We identify the root engineering cause, so you or your electrician can implement the precise, long-term fix.
How does your experience with utility infrastructure benefit local projects?
Our decades of designing and evaluating substations and transmission lines give us a unique perspective on how local electrical systems interface with the broader grid. This means our inspections consider not just your property's wiring, but also how grid-side events—like lightning surges—can impact it. We understand the standards and stresses that utility infrastructure faces, allowing us to assess vulnerability and recommend solutions that enhance overall resilience for homes and businesses in Addison.
