Industry Standards for Enclosures

Just thought I would give everyone a list of Standards for Enclosure Ratings, so here goes:

NEMA 1- For indoor use.  To previent accidental contact with enclosed equipment, in areas where unusual conditions do not exist. Protects from falling dirt.

NEMA 3R- For indoor or outdoor use.  To provide protection against windblown rain, Snow, Sleet and external formation of ice.

NEMA 4- For indoor or outdoor use.  To provide protection against wind-blown rain and dust, splashing or hose directed water, and external formation of ice.

NEMA 4X- Same as NEMA 4 with the addition of Corrosion Resistant.

NEMA 12- For indoor use.  To provide protection against dust, falling dirt, dripping non-corrosive liquids, lint, fibers, external condensation of non-corrosive liquids, and light splashing of water.

This list is for the most part the ones we deal in most cases.  There is this thing called NEMA 12 Ventilated.  This is a standard NEMA 12 that has Fans and Filters cut into it that are designed to trap dirt and other foreign materials from entering the cabinet.  In other words, it is for the most part a NEMA 1.

People seem to get confused about these ratings quite a lot of the time, so I thought this may be helpful to you all.

March News

The past few weeks have been challenging.  Madhu had a mild Heart Attack (if there is such a thing) and is currently still in the hospital with an infection in his lungs.  The news we are hearing seems to be the same everyday, that he is making progress in recovering little-by-little.  We are all praying for a speedy recovery for him.

Last week we had a booth at the RWAU annual meeting at the Dixie Center in St. George.  We were very pleased with the activity we had around the booth and talked to a lot of people from various cities around the state.  There still seems to be a lot of bad information out there about single phase applications for VFC's.  There is a posting I wrote a few months back about this if you need some more information on this subject.  If that still does not answer your questions, please feel free to call me and we can discuss single phase applications.

I have had a technical sales engineer here for the past few days from Williamson IR.  These folks sell Infrared Temperature measurement devices and their products are the best product on the market.  We just finished observing various test procedures that were being preformed by Shaw Pipe Company.  They do specialized coatings for pipe that is mostly for the petrochemical market.

The William Temperature Monitor is measuring the temperature of the pipe that is preheated just prior to applying the coating material.  The temperature is very critical to insure proper application of the coating.  The tests went very well and we hope they will be standardizing on the Williamson product in all their plants across the globe.

Williamson is the leader in Temperature Measurement for the Nonferrous Metals market, Iron and Steel processing, Flame-Fired Process and Engineered Materials.  For more information on Williamson, go back to our website, go to Resources, click on Williamson.  There, you can find a link to their website.  We have lots of literature and I would be happy to come out and talk to you about your application or specific need.

It is coming up on riding weather.  That means road projects, Asphalt, Concrete, Aggregate and building in general season as well.  Lets all hope for a productive spring, summer and fall and not too high fuel prices!  And when it comes to riding.......keep the shiney side up.
