Electrical Panel Upgrade for EV Charging in Henderson, NV
Many Henderson homes built before 2000 have 100-amp or 125-amp electrical panels that can't safely support a Level 2 EV charger. A licensed electrician can upgrade your panel to 200 amps, giving you the capacity you need for EV charging and future electrical demands.
What Is Electrical Panel Upgrade?
An electrical panel upgrade replaces your home's main breaker panel with a higher-capacity unit, typically from 100 or 125 amps to 200 amps. This provides enough electrical capacity to run your existing appliances, HVAC, and a Level 2 EV charger (which draws 40-50 amps) without overloading your system. The upgrade includes a new panel box, main breaker, branch circuit breakers, and often a new meter base.
Benefits
Typical Installation Process
Panel Assessment
The electrician inspects your current panel, calculates total electrical load including the EV charger, and determines the upgrade scope.
Permit & NV Energy Coordination
The electrician typically pulls the City of Henderson permit and coordinates with NV Energy for the meter disconnect and reconnection.
Panel Replacement
Remove old panel, install new 200-amp panel and breakers, reconnect all existing circuits, and add the dedicated EV charger circuit.
Inspection & Energization
City inspection, NV Energy meter reset, full system test, and EV charger installation if bundled.
Pricing
A 200-amp panel upgrade in Henderson typically costs $1,800-$3,500 depending on your existing wiring, meter base condition, and number of circuits. Bundling the panel upgrade with the EV charger installation can reduce total cost versus two separate projects; ask for bundled pricing.
Timeline
Panel upgrades take a full day (6-8 hours). Your power will be off for most of the day. NV Energy coordination adds 1-2 weeks to the overall timeline.
Frequently Asked Questions
How do I know if I need a panel upgrade?
If your panel is 100 amps or less, or if you have fewer than 4 open breaker spaces, you may need an upgrade for a Level 2 EV charger. A load calculation by the electrician confirms it.
Will my power be off all day?
Usually for most of the day (6-8 hours). The electrician coordinates the outage with NV Energy; ask to schedule it on a day that works for you.
Can I get the panel upgrade and EV charger installed at the same time?
Yes. Many electricians bundle both projects into one visit, which can save on labor. Ask for it when you request your estimate.
