Is it safe to charge my car using a NEMA 10-30 socket?

There are individuals online who claim that charging electric vehicles (EVs) on a 10-30 circuit is dangerous. In this article, we will examine this claim to uncover the truth.

It is accurate that a NEMA 14-30 circuit, which comprises two hot wires, one neutral wire, and one ground wire, is safer than a NEMA 10-30 circuit, which only contains two hot wires and a neutral wire, since it has a ground wire.

However, using a NEMA 10-30 circuit to power your dryer, home appliances, power tools, or charge your EV carries the same level of risk. As a result, it is misleading for people to claim that using a NEMA 10-30 circuit to charge an EV is more dangerous than using it to power other appliances.

In contrast, all of the safety-certified EV charging adapters (EVSE) we have seen, as well as the Splitvolt charging adapters, include current leak and short circuit detection systems that instantly shut off when they detect any current leak or short circuit. This feature makes charging an EV on a 10-30 circuit safer than using it to power a dryer or other electrical appliances.
