Ct P1 and E1 Mandatory Training 2006

It seems I'm losing ground with mandatory occupational training in place. I was disappointed in both programs this year. I grow tired of being hit over the head with wire size derating calculations again. I was happy with the code violating devices the E1 instructor passed around, but preparation for both seminars was shabby. I'm penalizing myself by attending early in the year, as instructors teach their first classes.

Disruptive students further reduced the quality of the program, though certainly providing entertainment.

I was taken aback by the assertion the state mandated the purchase of code change update book. I have no problem paying to update my code books, but being forced to purchase additional material after being updated on most changes as they were written in trade periodicals was infuriating. (I almost wish I could become angry)

On the bright side, rumor has it the program might be reduced in frequency to a 2 or 3 year cycle. Next year I'll be looking for known, trusted instructors names verses convenient locations.

Nameplates

The use of stick-on, typed nameplates should be banned. They wear out, and vital service information is lost, such as refrigerant charge. On HVAC units, they fade in sunlight. Often the manufacturer has no idea what they made, so they're useless as a backup. Look at an old methyl chloride unit with a stamped steel plate...still there!

Sloppy breaker workmanship

So I've chosen to complain my first blog. No. I'm not complaining. I am happy to find profit opportunities in the shortcomings of existing workmanship. I fix it, and leave the world a better place. My customer benifits from a safer, more secure facility...the stars smile upon me.

I had to reset a tripped breaker the other day, and discovered a 30 amp 2 pole feeding a single receptacle (Nema L6-20R) rated for 20 amp. As far as sins go, it's minor, though clearly a violation.

I also see GE breakers bolted into the WESCO panels. C'mon guys!!! Sure, it works, but article 110 asks we use UL Listed equipment. Is a GE breaker UL listed for a WESCO panel? If you look, you shall find. WESCO breakers, though expensive, are available...I can even find old FPE bolt ons.
