WHY REPLACEMENT MATTERS
UNDERSTANDING THE CONCERNS WITH ZINSCO PANELS
An older panel can appear to work normally while important breaker or connection problems remain hidden. Identifying the equipment and reviewing its condition are the first steps in planning replacement.
Unreliable Overcurrent Protection
Some Zinsco-type breakers may fail to trip as intended during an overload or short circuit, leaving wiring exposed to excessive current.
Overheating at the Bus Connection
Deteriorated breaker-to-bus connections can overheat or arc. The condition may not be visible from the front of the panel.
Condition Beyond the Cover
Decades of wear, corrosion, past repairs, and system changes can complicate the condition of older equipment.
Confirm the Panel Type
Zinsco-type equipment may carry Zinsco, Sylvania-Zinsco, or related labels. A professional review helps confirm the equipment and next steps.
A MODERN REPLACEMENT
WHAT A PLANNED PANEL REPLACEMENT CAN IMPROVE

Replace the aging assembly with suitable modern equipment and circuit protection selected for the electrical design.
A Clearer Circuit Layout

Capacity Based on Your Home

COMMON QUESTIONS
ZINSCO ELECTRICAL PANEL REPLACEMENT FAQ
How can I identify a Zinsco panel?+
Check visible labels without removing the cover. Zinsco-type panels may have colored breaker handles and related Sylvania branding. Appearance can vary, so professional identification is useful.
Can replacing only the breakers solve the problem?+
Replacement breakers do not address every concern with the bus connections or aging assembly. We review the equipment and explain why full replacement may be recommended.
Does replacement always mean upgrading to 200 amps?+
No. Panel replacement and a service-capacity upgrade are different scopes. The appropriate rating depends on the existing service, load evaluation, planned equipment, and applicable requirements.
What affects the cost and schedule?+
Panel location, service configuration, circuit work, access, permits, utility coordination, and inspections affect the scope. Photos and existing panel information help us begin the review.
