Whether you&#8217;re designing a residential home charging point or a commercial charging hub with multiple high-power stations, understanding these protection options is essential for ensuring safety, reliability, and regulatory compliance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\uc804\uae30\ucc28 \ucda9\uc804 \uc804\uae30 \ud658\uacbd \uc774\ud574<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">DC \uace0\uc7a5 \uc804\ub958 \ub3c4\uc804 \uacfc\uc81c<\/h3>\n\n\n\n<p>Modern EV chargers are sophisticated power electronic systems that convert alternating current (AC) from the electrical grid into direct current (DC) suitable for charging vehicle batteries. This conversion process involves rectifiers and switching power supplies that can generate smooth DC fault currents under certain fault conditions\u2014particularly insulation failures within the charger&#8217;s internal DC bus or charging cable.<\/p>\n\n\n\n<p>The critical safety issue arises from the nature of these DC fault currents. Standard Type A RCCBs use toroidal transformers to detect imbalances between live and neutral conductors. However, DC currents can saturate the magnetic core of these transformers, effectively &#8220;blinding&#8221; the protection device and preventing it from detecting subsequent AC faults. This phenomenon, known as DC magnetic saturation, creates a dangerous false sense of security where the RCCB appears functional but fails to provide protection when needed most.<\/p>\n\n\n\n<p>\uc804\uae30\ucc28 \uc804\ub3c4\uc131 \ucda9\uc804 \uc2dc\uc2a4\ud15c\uc5d0 \uc801\uc6a9\ub418\ub294 \uad6d\uc81c \ud45c\uc900\uc778 IEC 61851-1\uc740 \uc774\ub7ec\ud55c \uc704\ud5d8\uc744 \uba85\uc2dc\uc801\uc73c\ub85c \uc778\uc815\ud558\uace0 \uc788\uc2b5\ub2c8\ub2e4. \uc774 \ud45c\uc900\uc740 \ubaa8\ub4dc 2 \ubc0f \ubaa8\ub4dc 3 \ucda9\uc804 \uc2dc\uc2a4\ud15c\uc758 \uc6d0\ud65c\ud55c DC \uc794\ub958 \uc804\ub958\uc5d0 \ub300\ud55c \ubcf4\ud638\ub97c \uc694\uad6c\ud558\uba70, \uc720\ud615 B \uc794\ub958 \uc804\ub958 \uc7a5\uce58 \ub610\ub294 DC \uc624\ub958 \uac10\uc9c0 \uae30\ub2a5\uc744 \ud1b5\ud569\ud55c \ub300\uccb4 \ubcf4\ud638 \uccb4\uacc4\ub97c \uc758\ubb34\ud654\ud569\ub2c8\ub2e4.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\uaddc\uc81c \ud504\ub808\uc784\uc6cc\ud06c \ubc0f \uaddc\uc815 \uc900\uc218 \uc694\uad6c \uc0ac\ud56d<\/h3>\n\n\n\n<p>\uc804\uae30\ucc28 \ucda9\uc804 \ubcf4\ud638\uc5d0 \ub300\ud55c \uaddc\uc81c \ud658\uacbd\uc740 \uad00\ud560 \uc9c0\uc5ed\ub9c8\ub2e4 \ub2e4\ub974\uc9c0\ub9cc, \uc804 \uc138\uacc4\uc801\uc73c\ub85c \uc804\uae30\ucc28 \ucda9\uc804 \uc7a5\ube44\uc758 \uace0\uc720\ud55c \uc704\ud5d8\uc744 \uc778\uc815\ud558\ub294 \uc694\uac74\uc774 \uc810\uc810 \ub354 \uc5c4\uaca9\ud574\uc9c0\ub294 \ucd94\uc138\uc785\ub2c8\ub2e4. \uc774\ub7ec\ud55c \uc694\uac74\uc744 \uc774\ud574\ud558\ub294 \uac83\uc740 \uaddc\uc815 \uc900\uc218\ub97c \ubcf4\uc7a5\ud558\uace0 \ube44\uc6a9\uc774 \ub9ce\uc774 \ub4dc\ub294 \uac1c\uc870 \ub610\ub294 \uc548\uc804 \uc0ac\uace0\ub97c \ubc29\uc9c0\ud558\ub294 \ub370 \ud544\uc218\uc801\uc785\ub2c8\ub2e4.<\/p>\n\n\n\n<p><strong>\uc720\ub7fd \uc694\uad6c \uc0ac\ud56d:<\/strong>\\<br>In Europe, the 18th Edition of the IET Wiring Regulations (BS 7671:2018+A2:2022) mandates that each EV charging point must be individually protected by an RCD that disconnects all live conductors.
