Having an electric car is great and very much a trendy decision. When you have the EV of your choice parked in your garage, the most important question that follows is what size breaker does a Tesla need. Your electric car may save on fuel but it needs electric power to work, and this starts with a suitable breaker size.
The most efficient charging option is a level two charge and this usually requires up to 50 amps circuit. Your electrician can provide an estimate for installing this, but there’s a high possibility it will involve upgrading your electrical service panel. Older homes often carry a 100 amps breaker, which may be sufficient for the average homeowner who has very few power-demanding appliances. Hence, a Tesla charger just won’t fit and an upgrade to a 200 amp panel would be necessary. Also, the electrician will have to run a line of 40 or 50 amps to the charging spot.
If you already have a 200 amp service all that is left is to install the new circuit and run a line to the spot the charger will be used.
While this is an ideal option, not everyone can handle the cost or hassle of a new service panel. When this happens, there are still ways around it to ensure you can get the charge you need. A level one charger is a basic part of every Tesla and it can be plugged into any dedicated outlet. This outlet can deliver on 12amps of power and that translates to 40 miles during an overnight charging session. If this isn’t sufficient for you, you may consider charging at work or in public places. However, if you need about 100 miles or more, you may have to use the ideal solution of upgrading your panel and using a level 2 charge.
There’s also an option known as the slow level two charge which allows you to use the 30 amp plug used for appliances like the dryer. This allows the car to charge at 24 amps overnight. Bear in mind that the average Tesla can’t take over 32 amps, which is a 40 amps circuit in the first place. The 24 amps will give between 17-22 mph on Tesla models.
To make this work conveniently you can switch to a natural gas dryer. Yes, it will cost you, but the price might be more comfortable than a service panel upgrade. This way you can conveniently use that 30 amp plug for your Tesla.
