you are designing a solar array, you know the golden rule of electrical engineering: Wires must be protected by fuses or breakers. So, when you dig into the National Electrical Code (NEC) Section 690.9, you might run into a clause that stops you in your tracks. It suggests that if you have two strings of solar panels wired in parallel, you do not need to install fuses. This feels wrong. It feels like a typo. How can a power source not require protection? Welcome to the &#8220;Fuse Paradox.&#8221; This rule exists not because the NEC is lax on safety, but because the physics of a solar panel are fundamentally [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":20083,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[1],"tags":[],"class_list":["post-20076","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/posts\/20076","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/comments?post=20076"}],"version-history":[{"count":3,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/posts\/20076\/revisions"}],"predecessor-version":[{"id":20082,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/posts\/20076\/revisions\/20082"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/media\/20083"}],"wp:attachment":[{"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/media?parent=20076"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/categories?post=20076"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/tags?post=20076"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
