It's a different issue than terminals. When compared to a copper bar with the same cross-section there is a significant weight saving, up to 70% less, with an ampacity reduction of about 30%. 1.2 REFERENCES The most common temperature rating for aluminum bus, bus fittings, and disconnect switches is 30C over 40C ambient, or 70C operating temperature. Aluminum Bus Bar Ryerson's aluminum bus bar is made of 6101 aluminum alloy, noted for its electrical conductivity. However, a 1-inch-square copper bus bar has an ampacity of approximately 1,250A. AFL aluminum bus conductors are manufactured to meet appropriate ASTM specifications . With medium to high strength, good toughness and a good surface finish, it maintains most of the good qualities of aluminum. If the AWG of a wire is thicker than 0AWG, we don't go toward negative digits. Alcoa's name is synonymous with innovation. Order: 100 Pieces. In addition to proprietary alloys and value-add products, we offer commodity grade aluminum and low-carbon aluminum via our Sustana product line. Also known as Schedule 80, this pipe has extra-thick walls to handle high-pressure applications. Ampacity rating to be used when the long axis of the bars is in the horizontal plane, or .

Aluminum Pipe is a machined part widely used for all types of industrial projects where lightweight and corrosion resistance are the primary concern. I looked at that number too which would make this 2"x.25" bus good for 500 amps which to me seems about right when I compare it the bus in some other panels on site. Bus-bar trunking provides increased flexibility in design for future modifications. This was observed on samples exposed for 60 days in an industrial environment, and it is probably identical to that of bus bars in service. While is doesn't apply to this application, the NEC specifies the ampacity of copper bus at 1000 amp per square inch in 366.23 (A). Because aluminum has this imperfect surface, and is also subject to thermal expansion and contraction (which is 42% higher than copper) there is a greater risk that mechanical fasteners between bus bars will become loose. Pipe is aluminum, which is lightweight with good corrosion resistance. meter and copper conductor has Rs 3.0 per sqmm. Contact Hydro Extrusion today for more information.
