Dual EV Charger Installation.Two EVs, One Home, One Electrician
You bought your second EV and now you need a second charger. Or your partner bought their first EV and your existing charger cannot handle both vehicles overnight. Either way, the answer is a properly configured dual Level 2 charger installation done by a Tesla Wall Connector certified electrician who knows how to set up Power Management so both cars charge fully without tripping a breaker. DNZ Electrical Services handles dual EV charger installation throughout Thousand Oaks, Agoura Hills, Calabasas, Westlake Village, Moorpark, and Malibu. We are Tesla Wall Connector certified, EVITP certified, and an SCE Approved Contractor. Our shop is at 5627 Kanan Rd, Agoura Hills. CA License #1010883.
Before we get into the installation details, the most common question we hear is: do I need a panel upgrade to add a second charger? The answer is often no, and the section below explains why. If you want a quick read on whether your panel can handle both vehicles first, use our free electrical panel load calculator and come back with the result.
What is Tesla Power Management and why does it matter?
If you have two Tesla Wall Connectors connected to the same electrical circuit, Power Management is the feature that prevents them from pulling more amps than the circuit is rated for. Without it, two Wall Connectors both charging at full output could pull 96 amps from a 60-amp breaker, which trips the breaker within seconds.
With Power Management configured, the two Wall Connectors communicate with each other and share the available amperage. If your circuit supports 48 amps total, each Wall Connector gets 24 amps. If one car finishes charging at midnight and the other still needs power, the second Wall Connector gets the full 48 amps for the rest of the night. Both cars charge fully by morning. No breaker trips. No panel upgrade required in many cases.
Power Management only works between Tesla Wall Connectors. It requires a specific wiring configuration during installation and commissioning through the Tesla app. Our Tesla Wall Connector installation process includes Power Management setup on every two-charger job. A general electrician without Tesla certification cannot do this correctly.
DNZ is listed on Tesla's certified installer network for the Conejo Valley area. You can verify this at tesla.com/support/find-certified-installer by searching for Agoura Hills or Thousand Oaks.
Do you need a panel upgrade to add a second EV charger?
Not always. Here is how to think about it.
A Level 2 charger running at 48 amps requires a 60-amp dedicated circuit under the National Electrical Code continuous load rule. Two chargers running at 48 amps each would need two 60-amp circuits, pulling 120 amps from your panel just for the cars. On a 200-amp panel with existing household loads, that often exceeds what is left.
However, Tesla Power Management changes the math. Two Tesla Wall Connectors sharing one 60-amp circuit under Power Management only pull what is available at any given time. That means two Teslas can charge overnight on one 60-amp circuit without requiring a second circuit at all. Your panel only sees 60 additional amps rather than 120.
When you likely do NOT need a panel upgrade
- Both vehicles are Teslas and you are installing two Tesla Wall Connectors with Power Management
- Your panel is 200 amps with available capacity confirmed by a load calculation
- Your household loads are not already pushing the panel close to its limit
Use our free electrical panel load calculator to check your specific situation before calling. It runs a NEC 220.82 calculation based on your appliances and panel size and gives you an instant answer.
When you likely DO need a panel upgrade
- Both vehicles are non-Tesla and require separate dedicated circuits
- One vehicle is Tesla and one is non-Tesla requiring circuits for both simultaneously
- Your panel is 100 amps, which is common in Conejo Valley homes built before 1987
- Your 200-amp panel is already heavily loaded from HVAC, electric appliances, or previous additions
If a panel upgrade is needed, the panel upgrade for EV charger page covers the full cost breakdown and how the SCE Charge Ready Home rebate can cover up to $4,200 of the upgrade cost for qualifying households.
DNZ runs a full load calculation on every dual charger assessment visit. We tell you honestly whether your panel can handle both chargers before recommending any upgrade.
What does dual EV charger installation cost in Thousand Oaks and Agoura Hills?
Costs vary by scenario. The table below covers the most common configurations. All figures include hardware, labor, permit fees, and commissioning. Rebates and tax credits are applied afterward.
Before rebates and tax credits
Two Teslas, shared circuit, no panel upgrade: $1,800 to $2,800
Two Teslas, shared circuit, panel upgrade required: $4,800 to $7,500
Tesla plus non-Tesla, two circuits, no panel upgrade: $2,200 to $3,600
Two non-Teslas, two circuits, no panel upgrade: $1,800 to $3,200
Any scenario with panel upgrade, income-qualified SCE household: Subtract up to $4,200 SCE rebate
Any scenario, eligible census tract address: Subtract up to $1,000 federal 30C credit per charger
The federal 30C tax credit covers up to $1,000 per charging port installed. For a dual charger job that means up to $2,000 back on your federal taxes if both chargers qualify. See our EV charger federal tax credit guide for the full eligibility rules and the June 30, 2026 deadline.
The 30C federal tax credit expires June 30, 2026. DNZ is booking May and June now. Call 818-514-1417 to get your dual charger installation scheduled before the deadline.
Four common dual EV charger setups and how DNZ handles each one
Scenario 1 -- Two Teslas, 200-amp panel with capacity
This is the cleanest job DNZ does. Two Tesla Wall Connector Gen 3 units installed on a shared 60-amp circuit with Power Management configured through the Tesla app. Both units communicate with each other and share the 48 amps of available output. Each car gets between 20 and 24 miles of range per hour. An overnight charge from 9pm to 7am adds 200 to 240 miles to each vehicle.
Hardware: Two Tesla Wall Connector Gen 3 units at $445 each
Circuit: One shared 60-amp dedicated circuit
Panel upgrade: Not needed if panel has capacity
Total installed cost: $1,800 to $2,800 including hardware, labor, and permit
Timeline: One full day in most cases
Scenario 2 -- Two Teslas, 100-amp panel needing upgrade
Same setup as Scenario 1 but the panel is 100 amps. A panel upgrade to 200-amp service is needed first. DNZ completes the panel upgrade and dual Wall Connector installation on the same day in most cases. The SCE Charge Ready Home rebate applies to the panel upgrade portion. The federal 30C tax credit applies to the charger installation costs.
Hardware: Two Tesla Wall Connector Gen 3 units plus new 200-amp panel
Circuit: One shared 60-amp dedicated circuit added to new panel
Panel upgrade: Required -- 100-amp to 200-amp
Total installed cost: $4,800 to $7,500 before rebates
After SCE rebate and 30C credit: Reduced by up to $5,200 for qualifying households
Scenario 3 -- Tesla plus a non-Tesla EV
Mixed households need a different approach. The Tesla Wall Connector only charges Teslas natively, though the Universal Wall Connector ($600) includes a J1772 adapter for other brands. Alternatively, DNZ installs one Tesla Wall Connector on a dedicated circuit and one non-Tesla Level 2 charger on a second dedicated circuit. Power Management does not apply between different charger brands, so two separate circuits are needed.
We cover all major Level 2 EV charger brands including ChargePoint Home Flex, JuiceBox 40, Emporia, and Grizzl-E for the non-Tesla vehicle in a mixed household.
Hardware: One Tesla Wall Connector plus one non-Tesla Level 2 charger
Circuits: Two separate dedicated circuits -- one per charger
Panel requirement: 200-amp panel with capacity for two additional circuits
Total installed cost: $2,200 to $3,600 including hardware, labor, and permits
Scenario 4 -- Two non-Tesla EVs
Two separate Level 2 chargers, two separate dedicated circuits. No Power Management available between non-Tesla brands, though some chargers like the Wallbox Pulsar Plus have their own load-sharing feature when two units of the same brand are paired. DNZ assesses whether load sharing is available for your specific charger brand during the assessment visit.
Hardware: Two non-Tesla Level 2 chargers
Circuits: Two separate dedicated circuits
Panel requirement: 200-amp panel with capacity for two additional circuits
Total installed cost: $1,800 to $3,200 including hardware, labor, and permits

Questions homeowners ask about dual EV charger installation
Q: Can two Tesla Wall Connectors share one circuit?
Yes, with Power Management configured. Two Tesla Wall Connector Gen 3 units wired to a shared 60-amp circuit communicate with each other and divide the available amperage between them. If the circuit supports 48 amps total, each Wall Connector gets up to 24 amps while both cars are charging. When one car finishes, the other gets the full 48 amps. Both cars charge fully overnight in most cases. Power Management must be configured correctly during installation through the Tesla app. DNZ is a Tesla Wall Connector certified installer and handles this as part of every dual Tesla job. CA License #1010883. Call 818-514-1417.
Q: Does Power Management work between a Tesla Wall Connector and a non-Tesla charger?
No. Power Management only works between Tesla Wall Connectors. For a household with one Tesla and one non-Tesla EV, DNZ installs two separate dedicated circuits. Each charger runs on its own circuit independently. The panel needs to have capacity for both circuits. Call 818-514-1417 for a same-day panel assessment.
Q: Does the Tesla Universal Wall Connector work for both my Tesla and my partner's non-Tesla EV?
Yes. The Tesla Universal Wall Connector ($600) includes an integrated J1772 Magic Dock adapter that allows it to charge any EV with a J1772 connector, not just Teslas. This is a good option for mixed households who want one charger that handles both vehicles. The trade-off is that only one vehicle charges at a time on a single unit. For households where both drivers need to charge overnight simultaneously, two chargers on separate circuits is the better solution. Call 818-514-1417 to discuss which setup fits your schedule.
Q: How much does dual EV charger installation cost in Thousand Oaks or Agoura Hills?
Two Tesla Wall Connectors on a shared circuit with no panel upgrade runs $1,800 to $2,800 total including hardware, labor, and permit fees. A mixed Tesla and non-Tesla household needing two separate circuits runs $2,200 to $3,600. If a panel upgrade is needed first, add $2,500 to $5,000. The SCE Charge Ready Home rebate covers up to $4,200 of panel upgrade costs for qualifying households. The federal 30C tax credit covers up to $1,000 per charger installed before June 30, 2026. DNZ is an SCE Approved Contractor and handles the full rebate application.
Q: Do I need a panel upgrade to add a second EV charger?
Not always. If both vehicles are Teslas and Power Management is configured on a shared 60-amp circuit, your panel only needs capacity for one additional 60-amp circuit rather than two. Many 200-amp panels in the Conejo Valley have this available without an upgrade. If your panel is 100 amps, an upgrade is almost certainly needed regardless of the charger configuration. DNZ runs a full NEC 220.82 load calculation on every assessment visit and tells you the honest answer before recommending any work. Call 818-514-1417 for a same-day assessment.
Q: Can I add a second charger to the same circuit as my existing charger?
Only if both chargers are Tesla Wall Connectors and Power Management is configured. Adding a second non-Tesla charger to a circuit that already has a charger running at full output would overload the circuit and trip the breaker. DNZ assesses your existing installation during the assessment visit and confirms whether the second charger can share the existing circuit or needs a new one
Q: How long does a dual EV charger installation take?
A standard dual Tesla Wall Connector job with Power Management on a 200-amp panel takes one full day. A mixed household job with two separate circuits takes one full day. A job that includes a panel upgrade takes one full day with the panel work and charger installation completed in the same visit in most cases. DNZ coordinates the city permit and inspection scheduling as part of every job. CA License #1010883. Call 818-514-1417.
