ECN Forum Forums Code Related Discussion NEC & other Code issues Reducing Washers

All in favor of eliminating pre-punched knockouts on anything painted grey- raise your hands!

Hand up.

An alternative in many cases is to use reducing bushings with locknuts inside and outside.

An extreme gripe of mine is that small motors come with a 3/4" KO already knocked in them, heavily painted. It's a regular thing to find them with a 1/2" sealtite connector hanging by the conductors, RE washers floating around and a locknut floating on the inside :down:

What is with you guys? I'll bet that at least 1/2% of the times I've come across reducing washers, they have provided a good ground.
I hate those things!

.05% Wow that's bad. Did you mean 50%.

I'm sorry cheap shot but I'm a cheap shot artist.

George, you mean .5%? (cheaper shot)

Found this picture on another site and thought it would say it all.


Thank you, Joe Tedesco

First off, reducing washers are heavily used in my side of the biz. (Cinemas) Mainly on the flex for the DC leads to the Xenon lamp, though. Seems that the manufacturers of that equipment can't get on the same page and design a standard KO size for a given lamp type.

And did any of you catch the doublespeak in this from the UL white book? (Bold emphasis is added by me.)

It was a test Greg to see if you were watching.
