The three most common causes"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">The breaker, or circuit breaker, protects the wiring in your home. When it detects something dangerous, it cuts the power. These are the three most common causes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Overload<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It happens when you plug more devices into one circuit than that circuit can handle, for example a heater, a hair dryer and a microwave at the same time. The wire starts to heat up and the breaker cuts it off before it becomes dangerous.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. Short circuit<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It happens when a live wire touches another wire or a metal part because of damage, a faulty appliance or a loose connection. The current spikes and the breaker trips instantly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. Ground fault<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The current escapes along a path it should not take, for example through water. That is why bathrooms, kitchens, outdoor areas and garages use <strong>GFCI<\/strong> devices, which detect that leak and cut the power in a fraction of a second.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What about AFCIs?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>AFCI<\/strong> devices detect electrical arcs, sparks that occur in damaged wires or loose connections and that can cause fires. They are used on many bedroom circuits.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">An important tip<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If a breaker trips over and over, do not force it or replace it with a larger one: it is a sign that something on that circuit needs to be checked. In Florida, electrical work that requires a license must be done by someone who holds the state license.<\/p>\n\n\n\n<div class=\"ltcf-guia-cta\"><p class=\"ltcf-guia-cta__t\">In the Residential Electricity course you understand how the circuits, breakers and protections of a home work, with interactive practices.<\/p><div class=\"ltcf-guia-cta__b\"><a class=\"ltcf-guia-cta__p\" href=\"https:\/\/learningtcf.com\/en\/residential-electricity\/\">See the Electricity course<\/a><a class=\"ltcf-guia-cta__s\" href=\"https:\/\/learningtcf.com\/en\/prueba-electricidad\/\">Try a free practice<\/a><\/div><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Educational content from Learning Trade Center of Florida.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overload, short circuit and ground fault: why a breaker trips and what GFCI and AFCI devices do.<\/p>\n","protected":false},"author":5,"featured_media":35834,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_uag_custom_page_level_css":"","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":"default","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":[534],"tags":[],"class_list":["post-35842","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-guides"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Why does a breaker trip?
