Since 1925, Con J. Franke Electric has been powering Northern California’s growth—from water treatment plants and EV infrastructure to local K-12 schools and industrial hubs. ⚡

But almost a century in business has taught us one undeniable truth: high-quality builds start with how you treat your people.

That’s why we invest heavily in ongoing field training, prioritize safety above all else, and build a culture where work-life harmony actually matters. When you partner with us—whether as a client or a team member—you’re stepping into a century-strong tradition of reliability and pride in the craft.

💼 Ready to build something that lasts? Let’s connect.

When was the last time your building's electrical system had a routine health checkup? 📋💡

In business, the best electrical emergency is the one that *never happens*. While major power outages get all the attention, subtle warning signs often pop up weeks before equipment actually fails.

Here are 3 quick things our Service & Maintenance team looks for during a facility checkup:
1️⃣ Unexplained Buzzing or Warm Panels: A sign of loose connections or overloaded circuits.

2️⃣ Flickering Lights Under Heavy Loads: Usually means power isn't distributing evenly when large machinery kicks on.

3️⃣ Outdated Breaker Technology: Older switchgear that struggles to keep up with modern digital equipment.

A little preventative maintenance goes a long way toward keeping your doors open and your business running without interruption!

A water treatment plant that never sleeps. Over 25 dedicated Con J. Franke team members making sure the power never fails. 👷‍♂️👷‍♀️

Central San’s Solids Handling Facility in Martinez, CA, works 24 hours a day to protect public health and clean local wastewater. Delivering the complex electrical scope for Phase 1A of their facility upgrades takes a true team effort.

Behind every heavy conduit run, digital control panel, and power connection is a group of skilled professionals who take immense pride in what they do. From early planning and project management to our superintendents and electricians working side-by-side with plant operators, this project shows what our company culture is all about: Safety, Quality, Planning, and True Partnership.

Projects like this require skills built over a century of showing up for California’s most essential infrastructure. Shoutout to our CJF crews on-site in Martinez for keeping everything running smoothly! 👏

Is your workplace or commercial property ready for the modern parking lot? 🚗⚡

California is moving fast toward an electric future, and employees, tenants, and customers expect convenient charging options wherever they park. But adding commercial EV charging stations isn't just about bolting a charger to a wall!

It requires:
⚡ Evaluating your building’s main power grid to avoid overload.

⚡ Installing heavy-duty distribution panels that can handle multiple cars charging at once.

⚡ Setting up smart load-management software so power usage stays balanced.

At Con J. Franke Electric, we help business owners future-proof their properties with reliable, scalable EV infrastructure built to handle tomorrow's demand.

What’s the worst time to realize a building’s main power panel won't fit where you wanted it? *After* the walls are put up! 📐🏗️

That’s exactly why developers and general contractors lean on our Design/Build team from day one.

When we collaborate early with architects and builders, we can:
✨ Spot physical layout conflicts on paper before concrete is poured.

✨ Recommend energy-efficient power setups that cut long-term operational costs.

✨ Keep the entire electrical schedule running seamlessly alongside other trades.

Building a great commercial space shouldn't feel like a puzzle with missing pieces. Early collaboration makes all the difference!

Did you know that electrical contracting plays a direct role in keeping our local soil and water green and healthy? 🌾💧

At Central San’s Solids Conditioning Building in Martinez, CA, wastewater solids are processed through large hearth furnaces, wet scrubbers, and air-pollution control systems. Once processed, the leftover ash isn't just thrown away—it's repurposed for environmentally friendly agricultural use as a rich soil amendment!

Con J. Franke Electric is building the power and control foundation that connects these furnace retrofits (~80 burners each!), new energy-efficient equipment, and digital monitoring networks.

By modernizing the electrical infrastructure behind this facility, we’re helping extend the reliable operating life of Central San's treatment process by at least 15 years—keeping environmental protection at the highest standard for the Bay Area.

Powering smart infrastructure today for a cleaner tomorrow! 🟢

What happens when modern electrical technology meets 40-year-old building plans? You become an electrical detective. 🕵️‍♂️⚡

At Central San’s Solids Handling Facility in Martinez, CA, our team is upgrading equipment—like centrifuges and cake pumps—that has been running continuously for over four decades. Updating a facility that has been operating non-stop for that long is rarely as simple as reading the original blueprints. Over time, wires get re-routed, new equipment gets added, and legacy records don't always match field reality.

Before our Con J. Franke Electric crews could connect a single new wire, we performed a complete electrical investigation:
🔍 Tracing hidden conduits underground and behind walls.
🔍 Mapping out active systems versus old, abandoned wiring.
🔍 Carefully documenting digital control lines so no active equipment accidentally loses power.

By solving these hidden puzzles early, our team built a safer, smoother path for the plant's new upgrades. Before you build for the future, you have to master the past!

Quick question: How do you run high-voltage power to a boat dock without creating a major safety hazard in the water? 🛥️⚡

Water and electricity might sound like a dangerous mix, but marine electrical engineering is one of our favorite specialties!

To power modern marinas safely, our teams use:
🌊 Corrosion-Resistant Enclosures: Custom, fiberglass-reinforced materials built to survive harsh, damp salt-air environments.

🔌 Ground-Fault Protection: Ultra-sensitive safety monitors that shut off power in milliseconds if current leaks near the water.

⚓ Flexible Submersible Raceways: Heavy-duty conduits engineered to move naturally with rising tides and floating docks.

It takes specialized trade skills and extreme attention to detail to keep waterfront power safe, reliable, and built to code!
