Frequently Asked Questions

Panels with fewer than 100 amps can't support modern appliances, EV chargers, or home additions that increase electrical demand. Frequent breaker trips, visible corrosion, or obsolete panel types like Federal Pacific or Zinsco also indicate replacement rather than repair. Undersized panels limit what you can safely add to your electrical system.

A panel change replaces the breaker box inside your home to reorganize circuits or update outdated equipment. A service upgrade increases the electrical capacity supplied to your property by replacing the meter base, service lines, and panel together. Panel changes address organization and safety, while service upgrades address total electrical capacity.

Level 2 EV chargers require dedicated 240-volt circuits that draw 30 to 50 amps continuously. If your panel is already near capacity or lacks available breaker slots, you'll need either a panel change or service upgrade before installation. Undersized panels can't safely support the sustained load EV charging creates.

Check the main breaker rating—panels under 100 amps struggle with modern loads. Count available breaker slots for future circuits, and note if breakers trip repeatedly when running multiple appliances. Dimming lights or buzzing sounds when high-draw equipment runs also signal capacity issues that panel replacement addresses.

You can add circuits if the panel has available slots and sufficient amperage capacity for the new load. Panels at or near their rated capacity, lacking physical space, or containing obsolete components require replacement before adding circuits. A licensed electrician evaluates existing load and capacity before recommending additions or replacement.

Panel work involves the main electrical feed to your property, creating serious shock and fire risk if installed incorrectly. Kentucky code requires licensed electricians for service equipment changes, and permit inspections verify proper grounding, bonding, and circuit protection. DIY panel work voids insurance coverage and creates liability during property sales.

New panels allow electricians to group circuits logically by area or function, label each breaker clearly, and eliminate tandem breakers that crowd older panels. Proper organization makes troubleshooting faster, prevents accidental shutoffs, and creates room for future additions. Older panels often have unlabeled or incorrectly sized breakers that replacement corrects.

Existing branch circuit wiring remains in place and reconnects to the new panel's breaker positions. Electricians verify wire sizing matches breaker ratings, check for damage at connection points, and ensure proper grounding throughout. The main service wiring may also need updating depending on the new panel's capacity and local code requirements.

Additions require panel changes when existing capacity can't support the new circuits for outlets, lighting, HVAC, or appliances. Panels with available slots and sufficient remaining amperage can accommodate additions without replacement. The total load calculation determines whether your current panel works or needs upgrading before the addition's electrical work begins.

Electricians disconnect the main feed, mount and ground the new panel, reconnect branch circuits with proper torque and wire management, label all breakers, and test each circuit under load. The work includes verifying proper voltage, checking grounding continuity, and ensuring the panel meets current code before restoring power and scheduling final inspection.
