How can that be? It comes with a big nasty hole in the top and only a star bushing to plug it up!<\/p>\n<p>A: Turn it over so the hole faces down, and you\u2019ve got a NEMA 3R housing (unless you\u2019re in a location where the rain falls up). The hole in the Model ST-U package is designed to accept a conduit connector, and as long as the conduit entry is below the point of any wiring connections within, the NEMA standard is met. It\u2019s actually a good idea to have a hole in the bottom side of any outdoor enclosure to allow condensation to drain out, so the preferred conduit connector would not be a gasketed, liquid-tight type. If you\u2019re not using conduit in an outdoor application, a strain relief grip or other cable connector fitting is recommended to keep spiders and wasps from making a home in the sensor housing.<\/p>\n<p>The star bushing is for indoor use. It provides for easy ingress of cable and a moderate degree of strain relief in areas where insect invasion is not likely.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Q: Your literature shows that the ST-U Universal&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"full-width.php","meta":{"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"folder":[251],"class_list":["post-26987","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\r\n<title>NEMA 3R Rated Temperature Sensors - kele.com<\/title>\r\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\r\n<link rel=\"canonical\" href=\"https:\/\/www.kele.com\/content\/technical-reference\/temperature-sensors-and-transmitters\/nema-3r-rated-temperature-sensors\" \/>\r\n<meta property=\"og:locale\" content=\"en_US\" \/>\r\n<meta property=\"og:type\" content=\"article\" \/>\r\n<meta property=\"og:title\" content=\"NEMA 3R Rated Temperature Sensors - kele.com\" \/>\r\n<meta property=\"og:description\" content=\"Q: Your literature shows that the ST-U Universal...\" \/>\r\n<meta property=\"og:url\" content=\"https:\/\/www.kele.com\/content\/technical-reference\/temperature-sensors-and-transmitters\/nema-3r-rated-temperature-sensors\" \/>\r\n<meta property=\"og:site_name\" content=\"kele.com\" \/>\r\n<meta property=\"article:modified_time\" content=\"2024-06-18T15:01:57+00:00\" \/>\r\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\r\n<meta name=\"twitter:label1\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data1\" content=\"1 minute\" \/>\r\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\/\/www.kele.com\/content\/technical-reference\/temperature-sensors-and-transmitters\/nema-3r-rated-temperature-sensors\",\"url\":\"https:\/\/www.kele.com\/content\/technical-reference\/temperature-sensors-and-transmitters\/nema-3r-rated-temperature-sensors\",\"name\":\"NEMA 3R Rated Temperature Sensors - kele.com\",\"isPartOf\":{\"@id\":\"https:\/\/www.kele.com\/content\/#website\"},\"datePublished\":\"2023-09-01T20:59:57+00:00\",\"dateModified\":\"2024-06-18T15:01:57+00:00\",\"breadcrumb\":{\"@id\":\"https:\/\/www.kele.com\/content\/technical-reference\/temperature-sensors-and-transmitters\/nema-3r-rated-temperature-sensors#breadcrumb\"},\"inLanguage\":\"en-US\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/www.kele.com\/content\/technical-reference\/temperature-sensors-and-transmitters\/nema-3r-rated-temperature-sensors\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/www.kele.com\/content\/technical-reference\/temperature-sensors-and-transmitters\/nema-3r-rated-temperature-sensors#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\/\/www.kele.com\/content\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"NEMA 3R Rated Temperature Sensors\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\/\/www.kele.com\/content\/#website\",\"url\":\"https:\/\/www.kele.com\/content\/\",\"name\":\"kele.com\",\"description\":\"Kele is a single source supplier with a huge inventory for all your building automation requirements.
