Reno:
I was going to use your line of not beating a dead horse on this, but.....
Hubbell duplex receptacles, with an internal shutter over the slots, have been around for a long time. I do not have any factual info with dates, but I haven't slipped into dementia just yet.
As to if they were marked 'tamper resistant', or TR you possibly have a home run with that. They were special ordered thru a Hubbell distributor when they were specified on my jobs.I know I never referred to these devices as 'so called 'safety' devices'.
As to you stating "unenforceable" the 'spec/comm'grade designations are specifications called out by the design professional, and on many jobs the 'design professional' has been known to check devices for compliance.
As to the terms being 'meaningless' are you saying that ALL 'spec' grade devices are not equal? Or are you saying that 'spec' grade is non-existant.
