FAQs for electrical wiring or panel upgrade projects in Nassau, NY

Warning signs that indicate potential service line problems include frequent circuit breaker trips, flickering lights throughout your home, buzzing sounds from your electrical panel, or visible damage to exterior wiring. If your home has an older electrical panel (25+ years) or you notice a burning smell near your electrical connections, contact a licensed electrician promptly to evaluate your system's condition.

Responsibility for electrical service lines is divided between the utility company and the homeowner. The utility maintains everything up to the connection point at your property (often the weatherhead or meter), while you're responsible for the service entrance cables, meter base, and all wiring beyond. Contact your specific utility provider to understand exactly where their responsibility ends and yours begins.

A standard electrical service line replacement takes one to two hours for a straightforward installation. This timeline may extend if complications arise or additional electrical work is performed simultaneously. The process includes disconnecting power, removing old wiring, installing new components, and restoring service. Allow additional time for scheduling inspections and obtaining necessary permits.

Most standard homeowners' insurance policies don't cover electrical service line replacement due to normal aging or gradual deterioration. However, damage caused by covered perils like lightning strikes, fires, or fallen trees may qualify for insurance coverage. Some insurance companies offer specific service line coverage as an optional add-on to standard policies. Review your policy details or consult with your insurance agent to understand your specific coverage options.
