By request from @Rhys Hykawy, we all see L(xy)-(ab) on our twist lock power cables, but do we know what each variable means? The name L21-30 is a standard NEMA (National Electrical Manufacturers Association) designation that follows a specific code to describe its features . The breakdown of the name is as follows: - L: The prefix "L" stands for "locking," which indicates that the connector is a twist-locking type. When a locking plug is inserted into a locking receptacle, it is twisted to secure it in place, preventing accidental disconnection. - 21: This number identifies the specific NEMA series that the connector belongs to. The 21-series connectors are designed for three-phase Y-power configurations. - 30: This number indicates the ampere rating of the connector, which is 30 amps.  Therefore, the name L21-30 signifies that it is a Locking connector from the 21-series, rated for 30 amps. The "21-series" indicates it is intended for a 120/208V, 3-phase Y-power system. So, if you see a different designation (e.g., L5-20), you now know the amperage rating of your twist lock cable, and all you have to do to find out what voltage and phase type you need is to look up the NEMA code, which you can do here: (R = Receptacle, P = Prong)

LPEC Certification is something that anyone in the event industry can benefit from, especially those interested in specializing in event power. It is a pre-requisite to higher certifications like FE. Billy, owner of Event Power, created a free online course preparing you for your LPEC test. Check it out here: https://www.power-academy.ca/courses/learning-the-lpec APPLICATION PROCESS 1.
