Sparky, I'm not sure how changing a receptacle on an existing installation negates the listing of all other material and equipment connected to the circuit that was originally installed according to the manufactures instructions as well as the NEC at the time and is still functioning as intended.
I don't necessarily see that installed listed products or materials have an expiration date.
With add-ons and extensions from existing circuits... now here is where I am in agreement that the entire circuit must be updated to the current NEC.
