AC WORKS® Wisdom: The 80% Rule for EV Charging

Posted by Christopher Hahn on


With AC WORKS® brand adapters, you can charge your EV just about anywhere. From a regular household outlet, dryer outlets, generators, welder outlets, to industrial locking outlets, you’ll be covered.

There is just one thing to always remember when you charge your EV: to set a charging limit. Most Teslas can auto-sense what plug is being used for charging. One of the plugs that come with a Tesla is a NEMA 14-50P. This plug is rated for 50 amps, but Tesla limits it to 32 Amps, depending on the model and year. Let’s say you are adapting to a dryer outlet, either new or old style, to charge your EV. Since a 10-30 and 14-30 outlet are only rated for 30 Amps, the charger might try to overdraw and trip your breaker. To prevent this from happening, we always recommend manually setting your charging limit to 80% of what the outlet is rated for. In this example, you would set your charging limit to 24 Amps. If you need help with manually setting your charging limits, check our blog.
