FAQs
Our older San Mateo home's electrical system seems overloaded. What's the first step to make it safer and more reliable?
The first and most critical step is a thorough electrical inspection by a licensed professional. In many of San Mateo's beautiful older homes, the original panels and wiring weren't designed for today's power demands. We'll assess your system's condition, check for code violations, and identify any immediate safety hazards. This often leads to a recommended upgrade of your main electrical panel and service, which is the foundation for all other modern electrical work and ensures your home can handle appliances safely.
We're considering a backup generator because of occasional neighborhood outages. What does a proper installation involve?
A safe, reliable generator installation involves more than just placing the unit. Our process includes a site evaluation to determine the correct generator size for your home's needs, the installation of an automatic transfer switch (which safely disconnects your home from the grid when the generator kicks in), and professional connection to your home's electrical panel. We ensure the entire system meets local San Mateo codes and is properly permitted. This prevents back-feeding power to the grid, which is dangerous for utility workers, and ensures seamless power during an outage.
My circuit breakers trip frequently. Is this just an annoyance, or a sign of a bigger problem with my wiring?
Frequent tripping is a safety feature working as intended, but it's often a warning sign of a bigger issue, especially in homes with older electrical infrastructure. It could indicate overloaded circuits, faulty wiring, or a failing breaker itself. While a simple repair might fix it, persistent tripping often points to an underlying problem like inadequate circuit capacity or degraded wiring insulation. Our electricians can diagnose the root cause—whether it's a single faulty breaker, an overloaded circuit needing rewiring, or a sign that your entire panel needs an upgrade for safety.
