200-Amp Panel Upgrade in Pasadena for EV Charger — Before, During & After

Introduction

Many older homes in Pasadena and throughout Los Angeles were built with 100-amp electrical panels — more than enough for the 1960s, but far short of today's demands. When this Pasadena homeowner wanted to install an EV charger, we discovered their existing panel didn't have the capacity to support a new 60-amp circuit. The solution: a full 200-amp main panel upgrade. In this post, we'll walk through exactly what's involved — the permits, the LADWP coordination, the timeline, and the actual electrical work.

Why This Homeowner Needed a Panel Upgrade

The homeowner's goal was simple: install an EV charger at home. But after our load calculation, it was clear the existing 100-amp panel was already near capacity with their AC, kitchen appliances, and water heater. Adding a 60-amp EV charger circuit would overload the system. Rather than cutting corners, we recommended upgrading to a 200-amp panel — the current standard for modern homes. This gives them plenty of headroom for the EV charger and any future additions like a mini-split, electric dryer, or hot tub.

The Permit and LADWP Process — What Most People Don't Know

• Permit application: Panel upgrades require a permit from the city of Pasadena (or whichever city you're in). We prepare and submit the permit application on your behalf, including the load calculation and panel schedule.
• LADWP meter spot coordination: Since the upgrade involves a new meter base and increased service, LADWP (or your local utility) must approve and schedule the meter spot. This is where most of the wait time comes from.
• Wait time reality: The paperwork, permit approval, and utility coordination typically takes 3 to 5 weeks. This isn't something we can rush — it's a city and utility process. We keep you updated throughout.
• The actual work: Once permits are approved and the meter spot is scheduled, the physical panel upgrade work takes 1-3 days. We often do preparation work (mounting the new panel, running conduits) the day before the final switchover.
• Final inspection: After the work is complete, a city inspector verifies everything meets code. Once passed, LADWP energizes the new meter and your upgraded system is live.

What We Found: The Old Panel

When we opened up the existing panel, we found what we often see in older Pasadena homes: a packed breaker box with hand-written labels, limited space for new circuits, and wiring that showed its age. The panel was functional but maxed out — there was literally no room to add the EV charger circuit the homeowner needed. This is incredibly common in homes built before the 1990s across Pasadena, Altadena, and the San Gabriel Valley.

The Upgrade Process

• Day 1 — Preparation: We mount the new 200-amp panel, run new conduits, and prepare all connections. The old panel stays live during this phase so you keep your power.
• Day 2 — Switchover: LADWP disconnects the old meter. We transfer all existing circuits to the new panel, install the new main breaker, add the dedicated EV charger circuit, and connect the new meter base. The inspector verifies the work.
• Power on: After the inspection passes, LADWP installs the new meter and energizes your system. Your home is now running on a modern 200-amp service with room to grow.

Signs You Need a Panel Upgrade

• Your breakers trip frequently under normal use — running the microwave and AC at the same time shouldn't cause a trip.
• You're planning to install an EV charger, mini-split, or electric water heater — these high-draw appliances need dedicated circuits and available panel capacity.
• Your panel is a known problematic brand — Federal Pacific, Zinsco, Pushmatic, or Sylvania panels have documented safety issues. Many insurance companies now require replacement.
• You still have a fuse box — fuse boxes are outdated and don't provide the protection modern breaker panels offer.
• There's no room for new circuits — if your panel is full, you can't safely add new loads without an upgrade.
• You're remodeling or adding an ADU — major renovations typically require a panel upgrade to meet current code.

Panel Upgrade Cost Factors

The cost of a 200-amp panel upgrade in Pasadena depends on several factors: the complexity of the existing wiring, whether the meter base and service entrance need replacement, permit fees, and whether you're adding new circuits (like an EV charger) at the same time. We always provide a detailed, written estimate before starting work — no surprises. We also handle all permitting and inspection fees as part of the project.

Frequently Asked Questions

• Q: How long does a panel upgrade take from start to finish? A: The permit and utility coordination takes 3-5 weeks. The actual electrical work takes 1-3 days once everything is approved.
• Q: Will I lose power during the upgrade? A: Yes, temporarily. Power is off during the switchover day (typically several hours). We coordinate with LADWP to minimize downtime.
• Q: Do I need a 200-amp panel for an EV charger? A: If your current panel doesn't have capacity for a new 60-amp circuit, yes. We do a load calculation to determine this during our free estimate.
• Q: Is a panel upgrade worth it? A: Absolutely. A 200-amp panel supports modern electrical demands, adds resale value, satisfies insurance requirements, and gives you room for future upgrades.
• Q: Do you handle the LADWP paperwork? A: Yes — we handle permits, load calculations, LADWP coordination, and final inspection scheduling.
