Residential Panel & Meter Upgrade — Fire Prevention

Homeowner's existing service was maxed out and a meter-socket inspection revealed heat damage at the jaws. We replaced the meter socket, upgraded the main panel, and re-terminated every branch circuit with proper labeling — correcting a real fire risk and giving the home plenty of capacity for future loads.

Federal Pacific Stab-Lok Panel — Known Fire Risk

If your home or rental property has a Federal Pacific Electric (FPE) Stab-Lok panel, you are looking at one of the most well-known fire hazards in residential electrical work. Independent testing and the U.S. Consumer Product Safety Commission have linked FPE Stab-Lok breakers to high failure-to-trip rates during overload and short-circuit conditions — meaning the breaker may not shut off when it is supposed to, allowing wiring to overheat. Many home inspectors and insurers recommend replacing FPE panels entirely. The telltale signs: the FPE logo stamped on the cover, the words "STAB-LOK LOAD CENTER" on the inside label, and the distinctive red breaker tabs.
