Zinsco Panel Replaced With a 200A Solar-Ready Upgrade

Zinsco panels have a reputation in the electrical world - and not a good one. They were manufactured with a design flaw that causes breakers to fail to trip properly during a fault. That means instead of cutting power when something goes wrong, they can let the circuit keep running. That's a fire risk sitting right on the side of your house.

Here's what we were working with - an old Zinsco setup with a separate subpanel hanging below it. Two boxes doing a job that one modern panel can handle cleanly. We pulled it all out and replaced it with a new 200A solar-ready panel, consolidating the subpanel into a single main service unit. One clean install, properly sized for today's electrical demands and ready for solar if the homeowner decides to go that route down the road.

The difference between an outdated panel and a properly installed modern one isn't just about safety - it's about capacity. Older panels simply weren't designed for the load most homes carry today. EV chargers, heat pumps, upgraded HVAC systems - all of that demands more from your electrical service than a decades-old panel can reliably handle. A 200A service gives you room to grow.

What we ended up with is a tight, clean install with everything consolidated into one properly rated enclosure. No more separate subpanel, no more questionable breakers, and no more guessing whether the system is actually protecting the home. Just a solid, code-compliant panel that'll handle whatever gets added to it.

If your home is still running on a Zinsco, Federal Pacific, or any panel that hasn't been looked at in years, it's worth having a licensed electrician take a look. These aren't scare tactics - these are panels that insurance companies flag and home inspectors flag for a reason. We do electrical panel upgrades and replacements, and we're happy to walk you through what your home actually needs.
