  • Are the cable tray expansion joints and the cable tray clearances the same

    Are the cable tray expansion joints and the cable tray clearances the same

    The spacing between expansion joints varies and is determined by the type of metals and the extent to which there is a change in temperature. A typical joint spacing of an aluminum system is 65 feet for a typical temperature change of 100°F. The metal gets longer, and the heat becomes excessive. In case there is no space to move it, the tray could become deformed or break the bolts that attach. NEC Article 392 outlines the key rules for installing and maintaining industrial cable tray systems. These systems, made from metal or plastic, are open structures designed to support electrical conductors, ensuring proper organization and safety. Here's what you need to know: Cable Types: Only use. 1993 NEC Section 300-7 (b) states that “Raceways shall be provided with expansion joints where necessary to compensate for the thermal expansion or contraction.

  • Can a single fiber optic cable be used with a switch

    Can a single fiber optic cable be used with a switch

    The short answer is no - RJ45 connectors are designed for electrical Ethernet signals, while fiber optics transmit light pulses through glass or plastic. However, modern networks often combine both technologies. The good news: you can bridge them easily using the right hardware, such as media. If you have multiple Ethernet switches that need to be connected over long distances, fiber is obviously a preferred choice. So all PCs connected to each switch would reach the LAN/WAN from the other switch.
