It violates fundamental safety codes written to prevent exactly this scenario. The National Electrical Code (NEC) Section 240.4 states plainly that \"conductors...shall be protected against overcurrent in accordance with their ampacities.\" Bypassing this rule by installing an oversized breaker is not a clever workaround; it is creating a serious, code-violating fire hazard.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>\u91cd\u8981\u306a\u53ce\u7a6b<\/strong> \u30aa\u30fc\u30d0\u30fc\u30b5\u30a4\u30ba\u306e\u30d6\u30ec\u30fc\u30ab\u30fc\u306f\u3001\u56de\u8def\u306e\u4e3b\u8981\u306a\u5b89\u5168\u6a5f\u80fd\u3092\u7121\u52b9\u306b\u3057\u307e\u3059\u3002\u58c1\u306e\u914d\u7dda\u304c\u904e\u71b1\u3057\u3001\u4fdd\u8b77\u7d76\u7e01\u304c\u6eb6\u3051\u3066\u3001\u96fb\u6c17\u706b\u707d\u306e\u4e3b\u306a\u539f\u56e0\u3067\u3042\u308b\u30a2\u30fc\u30af\u30d5\u30a9\u30eb\u30c8\u304c\u767a\u751f\u3057\u307e\u3059\u3002.<\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">\u30d1\u30fc\u30c83\uff1a\u30d7\u30ed\u306e\u57fa\u6e96\uff1a\u6b63\u3057\u3044\u30a2\u30f3\u30da\u30a2\u5b9a\u683c\u306e\u9078\u3073\u65b9<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Now that you understand the danger, let\u2019s focus on the correct engineering approach.
