by Mike Becker | Reviewed by David Perez | Updated: Nov 7, 2022The 50 amp chargers deliver 12 kilowatts of power. Batteries can be recharged in four hours if a 20% discharged, medium-capacity electric vehicle battery is used as a charger. In one hour, a 50-amp charger will add 50 miles of range to an electric automobile. The rapid speed of these chargers is one of the reasons for their popularity.
Because most electric vehicles are restricted to 48 amps, they cannot accept more current. As a result, 50 amp versions are the optimal option for popular automobiles because they provide the quickest charging speed feasible.
A 50 amp Level 2 charger is more energy-efficient than a 40-amp plug-in (240V NEMA 14-50 outlet). The 70 amp breaker is required due to the 50 amp charger’s connection to the mains (electrical panel) alone.
Hardwired 50 Amp EV charging stations
Hardwired appliances offer a higher installation cost due to the fact that they must be hard-installed into your home by professionals. This type of connection is considered safe compared with plug in types, which can sometimes lead users into danger if not done properly or securely enough for their needs; but don’t worry – we have some great options below!

Check out this 50 amp electric car charger! It’s perfect for charging your batteries on the go. You’ll get 9,600W of power with a 240 volt supply and it can easily accommodate most vehicles- including those that are larger than what is typically seen at gas station pumps these days (think: Tesla).
Home charging stations can charge an electric car at different speeds. The faster the charge, the better! A 75 kW battery would take about 4 hours to fully recharge with a 40A charging station.
We all know NEMA 14-50 as the “High power residential socket” and it can be found in most homes. Devices that are not over 40 amps will fit onto this type, but there’s more than just electricity going on here! A lot of people also use these outlets for their plugs when they charge EVs like Tesla. Discover the full review of the NEMA 14-50 chargers here.
Level 2 Electric Vehicle (EV) charger is great for those who want to charge their electric car quickly. A Level 1 charger can take hours while a level 2 will do so in about 20 minutes!

If you’re an electrician, then you’re probably familiar with the 80% rule in the NEC code. But what is it? And how does it apply to EV chargers?
The 80% rule is a guideline in the National Electric Code that suggests that electrical circuits should be designed to carry no more than 80% of their rated load. This helps to ensure that the system is safe and reliable.
For example, if you have a NEMA 14-50 outlet (which has a maximum power rating of 50 amps), then your EV charger should not output more than 40 amps.
This is an important safety precaution, as exceeding the outlet’s maximum power rating could cause the wiring in the outlet to overheat and potentially start a fire. So when choosing an EV charger, be sure to take into account the maximum power rating of the outlet it will be connected to.

When it comes to EV chargers, there are a few things you need to consider before making a purchase. One of the most important factors is the power of the charger.
Chargers come in a range of amperages, so it’s important to choose one that can handle your vehicle’s charging needs.
Another important factor is connection type. The NEMA 14-50 wall plug (your EV gets 9.6kW) or direct hardwire connection (your EV gets 12kW) can be used to charge an EV. If you don’t have a dedicated EV charging port, you’ll need to get a charger with a NEMA 5-15 (1.4kW) plug.
Finally, it’s important to consider the wattage of the charger. Most high power EV chargers range from 7.2 kilowatt (kW) to 19.2 kW. A higher-wattage charger will charge your EV faster, but it will also cost more to operate.
When choosing an EV charger, it’s important to consider its power, connection type, and wattage. By doing so, you can ensure that you select a 50 amp charger that meets your needs and budget.

What is the Tesla charging speed of 50 amp?
Talk to an electrician and let them know that Tesla recommends NEMA 14-50. This is a 240V outlet with a 50 amp circuit breaker. This will charge the Tesla Model 3 at approximately 30 miles per hour.
Are all 50-amp plugs the exact same?
A 50-amp RV plug is not 240V or 120V. Two prongs on an RV plug typically have 120 Volts. The two prongs of an RV plug offer separate 50 Amp/120V, and a total voltage of 240V. If it has four prongs, a 50 Amp RV plug will only be 240 Volts.
Is it safe for an EV to be charged at 50 amps?
While charging at 50 amps can be fast, it is safe. Some models have a limit. Limits can be found in Mike Becker’s calculator.
Is it possible to charge Tesla using mains power?
Yes. All new Tesla cars come standard equipped with a Type G adapter (220 – 244 V). Depending on the car, this adapter provides between two and four miles per hour. I recommend installing a Wall Connector for the best home charging experience.
What does a 240-volt outlet look like?
Use the Google Image =) The 240-volt outlet has two vertical side holes, an L-shaped hole at the top and a bottom hole that looks half-circle. The ground wire is an extra feature in modern four-pronged outlets that prevents electrical shock. A 240-volt outlet measures approximately 4 1/2 inches high by 4 1/2 inches wide.
