Question:
Hello and Thank You for this Forum. Article 625.43 EVSE Disconnecting Means for more than 60A or 150V to ground - this code article seems ambiguous. It does not clearly state that the disconnect must be installed adjacent to or within sight of the equipment (just readily accessible), therefore the circuit breaker in the panel could serve this requirement if it complies with 110.25 for lockable in the open position. Your interpretation?

Hello Lance, and thanks for participating. Electric vehicle supply equipment is required to be listed so there should be installation instructions that must be followed to comply with Section 110.3(B). EVSE often includes a disconnecting means that is an integral part of the equipment. A breaker could serve as the required disconnecting means, and if not in sight of the equipment a provision for adding a lock at the circuit breaker meeting the requirements in 110.25 is often applied. Section 625.43 indicates that for equipment rated more than 60 amperes or more than 150 volts to ground, the disconnecting means shall be provided and installed in a readily accessible location. The disconnecting means shall be lockable open in accordance with 110.25.
