To run these cordsets safely, they need to be protected from environmental conditions that could compromise the cable jackets, and ultimately, expose the conductors. Many cordsets will need something to protect them further, leading to them being channeled through raceways or flexible/rigid conduit. This adds significant cost to the materials used and extra time for the installation of the power distribution network. However, an alternative exists. Using ER-rated cordsets can eliminate the extra cost of conduit, making it faster, easier, and more cost-effective to install the power network. As for securing these tap lines, an ER-rated cordset will only need to be secured every 6 feet (2 meters) to ensure it’s not inadvertently becoming entangled or hooked on people or other equipment.
Finally, looking at NFPA 79 and the NEC Tap Rule, when combined with ER-rated cordsets, those cordsets offer a cost-effective, safe, and efficient way to design and deploy distributed power networks. It reduces installation time, material costs, and complexity, especially in systems where tap conductors are under 25 A and run distances for those tap lines are under 25 feet — often seen in many intralogistics and intelligent assembly networks. Today’s factory managers are looking for safe yet affordable ways to distribute the power in their complex networks. Overmolded TC-ER-rated cordsets, used in accordance with the NEC Tap Rule, offer an easy option for plug-and-play replacement in the field. Connect with Phoenix Contact to learn more.
