For many modern EV chargers and inverter-driven loads, the equipment's internal power electronics can produce smooth DC leakage that a Type A device will not detect — making Type B the technically correct choice.\u003c\/p\u003e\n\n  \u003cp\u003eNot every EV charger installation requires Type B protection. The charger manufacturer's documentation will specify the required RCD type. If the documentation specifies Type A or Type AC, a Type A device is sufficient. If it specifies Type B, or if the charger contains a PFC stage or rectifier, Type B should be used.\u003c\/p\u003e\n\n  \u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n  \u003cdiv class=\"eh-faq\"\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eDoes every EV charger need a Type B RCD?\u003c\/summary\u003e\n      \u003cdiv class=\"faq-body\"\u003eNo — it depends on the charger. Some EV chargers include internal DC fault protection (often called RDC-DD) which means a standard Type A RCD is sufficient upstream. Others, particularly those without internal DC protection or with specific inverter stages, require Type B. Always check the charger manufacturer's installation documentation and your installer will confirm the correct device. If in doubt, Type B provides a higher level of protection and is always acceptable where Type A is required.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eWhat does 30mA tripping sensitivity mean?\u003c\/summary\u003e\n      \u003cdiv class=\"faq-body\"\u003e30mA is the standard tripping threshold for personal protection — it will disconnect the circuit when residual current reaches 30 milliamps, which is below the threshold likely to cause a lethal electric shock in most circumstances. This is the standard sensitivity required for EV charger and domestic circuits under BS 7671.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eCan I use a Type B RCD where a Type A is specified?\u003c\/summary\u003e\n      \u003cdiv class=\"faq-body\"\u003eYes. Type B provides a superset of the protection offered by Type A — it detects everything Type A detects, plus smooth DC currents. Using a Type B where Type A is specified is always technically acceptable, though it comes at a higher cost. Where the charger documentation specifies Type A, either type is compliant.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eDoes this RCD include overcurrent protection?\u003c\/summary\u003e\n      \u003cdiv class=\"faq-body\"\u003eNo. This is a standalone RCD (RCCB) providing residual current protection only. It does not include overcurrent or short-circuit protection. A separate MCB or RCBO is required for overcurrent protection, or the circuit must be protected upstream by an appropriately rated MCB.
