However, Ledes increased performance sharply by upgrading the formula and manufacturing procedure. That&#8217;s why Ledes passed the highest rating of the sunlight resistance test of UL. However, long-term exposure of any plastic pipe to direct sunlight will gradually deteriorate its physical properties. The ducts start yellow and turn brown at the end. At the same time, its impact resistance is getting weaker and weaker, and the most intuitive phenomenon is that the catheter becomes &#8216;brittle.&#8217; Therefore, during our project, if we need to store it in an outdoor environment for a long time (for example, more than six months), we need to cover it with a tarp or other opaque materials in advance and keep air circulation at the same time, pipes need to be stored on a supported cover.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-5595\" class=\"elementor-tab-title\" data-tab=\"5\" role=\"button\" aria-controls=\"elementor-tab-content-5595\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><svg class=\"e-font-icon-svg e-fas-angle-down\" viewBox=\"0 0 320 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M143 352.3L7 216.3c-9.4-9.4-9.4-24.6 0-33.9l22.6-22.6c9.4-9.4 24.6-9.4 33.9 0l96.4 96.4 96.4-96.4c9.4-9.4 24.6-9.4 33.9 0l22.6 22.6c9.4 9.4 9.4 24.6 0 33.9l-136 136c-9.2 9.4-24.4 9.4-33.8 0z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><svg class=\"e-font-icon-svg e-fas-minus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">The schedule 40 & 80 conduit and fittings can install in concrete?<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-5595\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"5\" role=\"region\" aria-labelledby=\"elementor-tab-title-5595\"><p>Yes.

Schedule 80 PVC conduit has a thicker wall. It should be noted that the outer diameters of both are the same.<br \/>In addition, the Sch 80 PVC conduit has better physical performance because of the thin wall. For example, in the description of the Load for the crushing test in UL 651, among all sizes of Sch 40 conduit, the minimum test result is 700 lbf, about 3,113 N, while all sizes of Sch 80 conduit require 2,000 lbf, about 8,896 N. Because of the thicker wall, the Sch 80 PVC conduit is doing better.<br \/>Finally, because of the different wall thicknesses, Sch 80 conduit of the same length uses more PVC raw materials, so the price of Sch 80 PVC conduit is higher than Sch 40 PVC conduit.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-55919\" class=\"elementor-tab-title\" data-tab=\"19\" role=\"button\" aria-controls=\"elementor-tab-content-55919\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><svg class=\"e-font-icon-svg e-fas-angle-down\" viewBox=\"0 0 320 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M143 352.3L7 216.3c-9.4-9.4-9.4-24.6 0-33.9l22.6-22.6c9.4-9.4 24.6-9.4 33.9 0l96.4 96.4 96.4-96.4c9.4-9.4 24.6-9.4 33.9 0l22.6 22.6c9.4 9.4 9.4 24.6 0 33.9l-136 136c-9.2 9.4-24.4 9.4-33.8 0z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><svg class=\"e-font-icon-svg e-fas-minus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">What Does 90\u00b0C Wire Mean and Why It Matters?<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-55919\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"19\" role=\"region\" aria-labelledby=\"elementor-tab-title-55919\"><p>The 90\u00b0C rating refers to the maximum temperature the wire\u2019s insulation can withstand without degrading over time. UL 651-certified PVC conduit is typically rated for 75\u00b0C conductors, but many electrical specifications now demand 90\u00b0C-rated conduit to accommodate higher-temperature wiring without requiring system derating. This higher temperature tolerance ensures that the electrical system operates at full efficiency while maintaining safety and reliability.<\/p><p>To achieve a 90\u00b0C rating, PVC conduit must pass additional long-term testing beyond the standard requirements for 75\u00b0C conduit.

However, long-term exposure of any plastic pipe to direct sunlight will gradually deteriorate its physical properties. The ducts start yellow and turn brown at the end.

The difference between the two is the wall thickness. Compared with Schedule 40 PVC conduit, the Schedule 80 PVC conduit has a thicker wall, meaning it has higher impact resistance. That\\u2019s why NEC was saying this.<\\\/p>\"}},{\"@type\":\"Question\",\"name\":\"Schedule 40 & 80 PVC conduit to penetrate fire-wall or ceilings?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"<p>Yes, all listed PVC conduits can be used in this manner.

Schedule 80 PVC conduit has a thicker wall. It should be noted that the outer diameters of both are the same.<br \\\/>In addition, the Sch 80 PVC conduit has better physical performance because of the thin wall. For example, in the description of the Load for the crushing test in UL 651, among all sizes of Sch 40 conduit, the minimum test result is 700 lbf, about 3,113 N, while all sizes of Sch 80 conduit require 2,000 lbf, about 8,896 N. Because of the thicker wall, the Sch 80 PVC conduit is doing better.<br \\\/>Finally, because of the different wall thicknesses, Sch 80 conduit of the same length uses more PVC raw materials, so the price of Sch 80 PVC conduit is higher than Sch 40 PVC conduit.<\\\/p>\"}},{\"@type\":\"Question\",\"name\":\"What Does 90\\u00b0C Wire Mean and Why It Matters?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"<p>The 90\\u00b0C rating refers to the maximum temperature the wire\\u2019s insulation can withstand without degrading over time. UL 651-certified PVC conduit is typically rated for 75\\u00b0C conductors, but many electrical specifications now demand 90\\u00b0C-rated conduit to accommodate higher-temperature wiring without requiring system derating. This higher temperature tolerance ensures that the electrical system operates at full efficiency while maintaining safety and reliability.<\\\/p><p>To achieve a 90\\u00b0C rating, PVC conduit must pass additional long-term testing beyond the standard requirements for 75\\u00b0C conduit. The testing process outlined in UL 651 extends over 360 days, exposing the conduit to various environmental stresses, including prolonged high temperatures, to evaluate its resistance to thermal degradation, mechanical integrity, and overall performance.<\\\/p>\"}},{\"@type\":\"Question\",\"name\":\"Is Ledes Schedule 40 & 80 Conduit Rated for use with 90\\u2103 Wire?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"<p>Yes, all Ledes Schedule 40 &amp; 80 Conduit listed for 90\\u2103 Wire.<\\\/p>\"}}]}<\/script>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-4a99ed6 e-flex e-con-boxed e-con e-parent\" data-id=\"4a99ed6\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-2d712da e-flex e-con-boxed e-con e-child\" data-id=\"2d712da\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-e728d70 elementor-widget elementor-widget-heading\" data-id=\"e728d70\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Still Have Questions?
