This video shows you how to select the correct circuit breaker size for your EV charger 240v circuit.
This is information NO ONE is telling you.
FAQ
--------------
1. MY UTILITY PROVIDES 24HR OR MONTHLY DATA, COULD I USE THIS?
24hr or monthly data sets are not helpful and should not be used, as it averages down maximum demand. Reach out to your utility provider and request 15min.
2. WHAT IF MY UTILITY PROVIDER CANNOT PROVIDE 15 MIN DATA?
Reach out to your provider and request 12 months worth of monthly maximum demand (units = kilowatts). Some utility providers might not provide this to residential customers, but it is FREE to ask for it.
3. I JUST MOVED INTO MY HOME AND I DONT HAVE 12 MONTHS WORTH OF DATA.
The electrical code requires 12 months worth a data to do a proper analysis. Analysis cannot be performed with limited or no data. Here some options: 1) Contact your local certified electrician and he/she will make an assessment and judgment call based on existing conditions.
2) A DCC-12 device is available (link here: [ Ссылка ] ). This is a 3rd party electrical meter/control unit that prevents your EV charger from overloading your electrical panel. Contact your local electrician for additional guidance.
4. AN EV CHARGER REQUIRES 2 EMPTY SLOTS INSIDE YOUR ELECTRICAL PANEL, MY PANEL DOESNT HAVE ENOUGH SPACE.
An electrical panel upgrade can be expensive. DCC-9 can be a solution for you, link here: [ Ссылка ] Contact your local electrician for additional guidance.
5. WHAT SIZE WIRE SHOULD I USE FOR MY CIRCUIT?
The larger the breaker the larger the wire required.
Refer to my other video here: [ Ссылка ] @ 1:38 for recommended MINIMUM wire sizes.

EV CHARGERS TO CONSIDER
--------------
Tesla J1772 Wall Connector Black (this unit has the Universal J1772 Plug)

ChargePoint 50Amp Nema 14-50 Plug (this unit has the Universal J1772 Plug)
[ Ссылка ]
I recommend the Black Tesla J1772 Wall Connector to everyone for 2 Reasons.
1) This unit's wire terminal accepts #4 gauge copper wire. All other non-tesla chargers (ChargePoint,Clipper Creek, etc.) take #6 gauge maximum.
2) The unit has the universal plug J1772 which will charge ANY electric car. This is great especially if you sell or rent out your home. Tesla owners have to use the adapter, which is included with the car.
