Zinsco / Sylvania Panels in Florence, SC — Why We Replace Them
Zinsco panels can fail to trip and overheat — another brand we evaluate and replace.
Zinsco / Sylvania in the Pee Dee
Zinsco (and Zinsco-branded Sylvania) panels are the other older brand with a known safety problem. The breakers can appear to be off while still passing power, and the aluminum bus can melt or burn at the breaker connection, leading to overheating and fire risk. Palmetto Electric evaluates and replaces Zinsco panels throughout Florence and the surrounding Pee Dee.
As with Federal Pacific, we'll show you exactly what you have and give you a straight recommendation — usually replacement, because the failure mode is in the design, not just one bad part.
Why it matters for your home
Zinsco breakers have been documented failing to trip and can fuse to the bus, while the aluminum bus bars are prone to overheating and burning at the connections. These are design-level issues you can't fix by swapping a breaker, so a modern replacement panel is the safe path.

How can I tell if I have a Zinsco panel?
Look for ‘Zinsco’ or ‘Sylvania’ markings, often with colorful (blue, red, green) breaker handles and a distinctive bus. We can identify it during a visit.
Why are Zinsco panels considered unsafe?
Breakers can fail to trip and even fuse to the bus, and the aluminum bus can overheat and burn at connections — both serious fire risks documented over the years.
Is replacement really necessary?
Because the issues are built into the design, the reliable fix is replacing the panel with a modern, listed load center. We'll explain the specifics for your panel.
Can you replace a Zinsco panel in a day?
Most Zinsco replacements are completed in a day with the utility disconnect and reconnect, permitted and inspected. Call (843) 595-9236.
