This device acts as the first line of defense. It stops large surges, such as those from lightning or power grid problems, before they reach your wiring and outlets. You protect your entire home or business with this type. Service-entrance SPD ratings and any required backup overcurrent protection depend on the specific device and its installation instructions.<\/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\">Tip: If you want the best protection for your whole house, start with a service entrance surge protector.<\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">Branch Panel<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You place a branch panel surge protective device at subpanels or distribution boards inside your building. This device gives you a second layer of protection. It catches any surges that get past the main panel or come from inside the building, such as from large appliances turning on and off. You use branch panel devices to protect groups of rooms or specific areas. These devices often require extra overcurrent protection and handle moderate surge currents.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Point-of-Use<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You plug point-of-use surge protective devices directly into wall outlets near your sensitive electronics. These devices protect single items, such as computers, TVs, or medical equipment. Point-of-use protectors can add local protection for sensitive electronics. See our <a href=\"https:\/\/cnkuangya.com\/ar\/blog\/whole-house-surge-protector-vs-power-strip\/\">whole-house SPD vs power strip comparison<\/a> for how the two approaches differ. They are effective for sensitive electronics, but you should use them as part of a complete surge protection plan for the best results.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common devices you protect with point-of-use surge protectors include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p>Television<\/p><\/li>\n\n\n\n<li><p>Personal computer<\/p><\/li>\n\n\n\n<li><p>Fax machine<\/p><\/li>\n\n\n\n<li><p>Home automation system<\/p><\/li>\n\n\n\n<li><p>Stereo equipment<\/p><\/li>\n\n\n\n<li><p>Modem<\/p><\/li>\n\n\n\n<li><p>Microwave oven<\/p><\/li>\n\n\n\n<li><p>Alarm clock<\/p><\/li>\n\n\n\n<li><p>Electronic telephone<\/p><\/li>\n\n\n\n<li><p>Printer<\/p><\/li>\n\n\n\n<li><p>Security system<\/p><\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Note: Point-of-use surge protectors help keep your electronics safe, but they work best when you also have whole-house surge protection in place.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">\u0627\u0644\u0645\u0632\u0627\u064a\u0627<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">\u062d\u0645\u0627\u064a\u0629 \u0627\u0644\u0645\u0639\u062f\u0627\u062a<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You rely on your electronics every day.
