Information
Definition
Rated current is the maximum current a charger or electrical component is designed to carry under specified conditions. It is normally assessed during product selection, circuit design, installation verification and maintenance of EV charging equipment.
Why it matters
It affects circuit protection, cable sizing, charging power and whether a charger can operate safely at its stated output. For UK users, it supports safer specification decisions and reduces the risk of misunderstanding how a charger should be protected or installed.
