Hello!
I am in the process of repairing fixtures and cables at a theatre that has not had much maintenance over the past decade. I discovered a discrepancy in the twist lock connectors when I tried to swap a new one from our stock with an existing one. The ground pin for the new plug was facing inwards and on the existing connectors, the ground pin was facing to the outside (See pictured, these are what are installed in the raceways and all breakout circuits).
I consulted my trusty backstage handbook, assuming someone just ordered the wrong ones. The arrangement of pins on the L6-15 matches the arrangement of pins on one of the 20A obsolete locking type receptacles, which leads me to believe the connectors installed in the theatre are obsolete. I have struggled to find information about this, but hope to get some answers here.
1. Is there a reason (other than inconvenience) that I would need to update all connectors to L6-20, assuming all are in good condition?
2. Why is this connector obsolete now? Is there a reason only one of the connectors pictured (L6-15) has the pin facing outwards? (just curious)
As of now, my plan is to use adapters between the L6-20 connector and the outdated ones for fixtures that have had their connectors updated.
Thanks!
