Think of a breaker as a guardian angel for your electrical system. <\/p>\n\n\n\n
It’s responsible for protecting against overloads and faults that can lead to dangerous situations. Choosing the right breaker switch size ensures your charging experience is safe, efficient, and hassle-free.<\/p>\n\n\n\n
Things To Consider When Choosing a Breaker Size for a Tesla Charger<\/h2>\n\n\n\n Now, let’s explore the essential factors to consider when determining the appropriate breaker box size for your Tesla charger.<\/p>\n\n\n\n
Tesla Charger Specifications<\/h3>\n\n\n\n First up, take a look at your Tesla charger’s specifications. Tesla offers different models, each with varying power ratings measured in watts or kilowatts. <\/p>\n\n\n\n
The charger’s power rating directly influences the breaker size you’ll need. So, knowing this information is crucial.<\/p>\n\n\n\n
Electrical Voltage<\/h3>\n\n\n\n Next, let’s talk about electrical voltage. Most residential buildings in the United States operate at a standard voltage of around 240 volts. <\/p>\n\n\n\n
The relationship between the charger’s power rating and the electrical voltage is vital when calculating the breaker size. It’s this interplay that helps determine the ampere (amp) rating needed.<\/p>\n\n\n\n
Electrical Code and Regulations<\/h3>\n\n\n\n Before proceeding further, keep in mind that local electrical codes and regulations may have specific requirements regarding breaker sizes. <\/p>\n\n\n\n
To ensure compliance with these regulations, it’s highly recommended to consult with a licensed electrician. They’ll be familiar with the local codes and can guide you accordingly.<\/p>\n\n\n\n
It’s also important that you don’t fiddle with electrical boxes if you don’t have any electrical experience! Rather hire a professional who has the correct tools and knowledge. <\/p>\n\n\n\n
Calculating the Breaker Size<\/h2>\n\n\n\n Now, let’s crunch some numbers to answer your question, “What size breaker do I need for a Tesla charger?” <\/p>\n\n\n\n
Calculating the breaker size involves a simple formula:<\/p>\n\n\n\n
Breaker size (in amps) = Charger power rating (in watts) \/ Electrical voltage (in volts)<\/strong><\/p>\n\n\n\nFor example, if your Tesla charger has a power rating of 14.4 kW and the electrical system operates at 240 volts, the calculation would be:<\/p>\n\n\n\n
Breaker size = 14,400 W \/ 240 V = 60 amps<\/p>\n\n\n\n
In this scenario, a 60-amp breaker would be suitable for your charger.<\/p>\n\n\n\n
Additional Considerations for Breakers<\/h2>\n\n\n\n While the above formula provides a useful starting point, it’s essential to be aware of other factors that might influence the breaker size. <\/p>\n\n\n\n
Wire gauge, wire length, and specific electrical code requirements can impact the overall setup. To ensure a safe and accurate recommendation tailored to your specific needs, it’s wise to consult with a qualified electrician. They’ll evaluate your electrical system and provide personalized guidance.<\/p>\n\n\n\n
When choosing a breaker needed for a Tesla charger, you can also consider the following factors.<\/p>\n\n\n\n
Consider Your Desired Charge Rate<\/h3>\n\n\n\n The standard way to measure charge rate is the charge per hour – for example, the standard you should be looking to have is around 40 miles per hour (64 kph). This, of course, will differ depending on the charging method you use for your vehicle. <\/p>\n\n\n\n
There are numerous ways to charge a Tesla: at work, at home, or using portable devices on the road. <\/p>\n\n\n\n
If we focus specifically on the requirements to charge at home, we\u2019re looking at you getting 44 miles (70.8 km) of travel distance out of around an hour of charging. Wall charging is the fastest speed for home or office charging options and gives you the most range in a set amount of time. <\/p>\n\n\n\n
Looking at other options offers varying results – let\u2019s lay them out in table format so you can tell the difference the charge rate makes.<\/p>\n\n\n\nHardware<\/strong><\/td>Charge rate<\/strong><\/td><\/tr>Wall connector<\/td> 1 hour charge = 44 miles (70.8 km)<\/td><\/tr> Mobile connector + 120V outlet adapter<\/td> 1 hour = 3 miles (4.8 km)<\/td><\/tr> Mobile connector + 240 V outlet adapter<\/td> 1 hour = 30 miles (48.2 km)<\/td><\/tr> Supercharger<\/a><\/td> 15 minutes = 200 miles (321.9 km)<\/td><\/tr> Destination charger<\/td> 1 hour = 44 miles (70.8 km)<\/td><\/tr><\/tbody><\/table>This is a table that shows the charge rates of different chargers outlining the charge rate of a range of connectors, specifying the miles (kilometers) you can travel for particular charge times. <\/em><\/figcaption><\/figure>\n\n\n\nThe charging speeds do vary, depending on the % charged level of your car battery. The longer it gets charged, the slower it charges. Clearly, some charging methods are better than others. One hour charge time to move 3 miles? Nobody has time for that!<\/p>\n\n\n\nWe know where to find all the really good stuff, so we recommend that you take a look at this Tesla Motors 24′ Wall Connector<\/a> from Amazon. <\/em><\/figcaption><\/figure>\n\n\n\n\u201cAnd what will this cost me?\u201d<\/strong> I hear you ask with a clenched jaw. Well, it doesn\u2019t have to break the bank! Watch this Alex Sibila YouTube video about what it costs to charge a Tesla, how you can reduce this cost, and how to factor charge rate into these equations. <\/p>\n\n\n\nAs an added bonus to this article, I\u2019ve created this easy-to-use charging calculator. Simply input your model, charging wattage, and charging percentage, and you will get the estimated time it will take to charge a Tesla in terms of hours. You can play around with numbers a bit just to see how charging time changes:<\/em><\/p>\n\n\n\n\t
