while instructing an apprentice at running conduit for a machine change today some contractors were installing a varimot drive motor with the assistance of the manufacturers tech.
they frogged around with the motor for nearly 3 hours trying to get it to run.
including changing out the motor and inverter head!

i remembered the varimot drives will show a fault and shut down the motor to prevent the motor from single phasing should it lose a leg.
when i mentioned this bit of info i had my guys meter the legs and what do you know they found leg one dead (new fuse but faulty)

i mean really this is a rookie mistake to not check the fuses and supply legs to a motor
what kinda crap do they teach these techs?
 
Perhaps these manufacturing tech didn't have enough field experience, possibly so used to their in house own proved test jigs?

But yeah they should have check if all phases are in.

Not a lot if that is anything to go by!!
Which just shows the importance of testing and the all important ability of fault finding....

they sound like idiots.

i know on danfoss inverters etc you need to put a couple links in to get them to run.

its all in black and white in a book that comes with every inverter.

why they techs didn't check for V first no one will ever know
 
You have had an interaction with a certified idiot so does that make all Technicians the same? ... The world is full of numpties with titles well above their station for whatever reason but you shouldn't paint everyone with the same brush just because you meet one or two... he's probably a paper pusher lacking practical experience and yes! probably getting paid more than his worth but just ask him how a person holding a technician level of recognision does not do something so basic as testing and checking all voltage is present - a fundamental test, now yes complacency may play a part but when the drive didn't work it would be the first thing to check IMHO ... so ask him and revel in humour at his attempt to save face.

Makes you wonder how many days or weeks training the manufacturers techs get before they are let loose
 
Always a chuckle if someone doesn't check fuses as a starter for ten. I've even seen experienced guys do it when a fault looks like a common one thats nothing to do with supplies but turns out otherwise.

Well I feel I still have mine, HTHs.

So you’ve never overlooked anything basic then? If you say you haven’t I’ll call you a liar to your face.

only one time when i was a rookie and i still remember the painful jolt from a capacitor bank quite well!
i must admit it did wonders to improve my ability to pay attention to details and procedures

i cant label all techs like those guys many ive met were top notch
but it made me wonder why they missed that ( i think these guys were in a bit of a hurry to finish up and it kind of bit them in the rear)
 
If I have offended anyone here it was not my intention. I signed up on this site to learn better and safer ways to improve the skills of my apprentices, but due to the rampant anti-american abuse ive had to endure it has seriously soiled the memory of the british gent who introduced me to the electrical trade.
I have not meddled if british affairs I have observed and asked questions only!
I have not tried to change policies in the uk nor would i ever interfere with them.
I was not tarring the entire technician trade as tony implied, I merely asked a funny question as to why the techs missed such a basic issue. (read the reply while i was at work and since then it has been removed)

many of you chaps have been decent to me and have helped me with information and site links.
For this I am very grateful.
some of you I can honestly refer to as friends. and for that I am also grateful.

but since Im not worthy enough in the eyes of some of you I will not bother to return!
I am a very tolerant person but even I have a limit.

to any admin or friends i have here you may contact me if you wish but that is your choice
 
As my question has been deleted I’ll ask again.

Why come on to a British site for information so you can teach your “apprentices”? A site where most work to BS7671 and not the NFPA-NEC

This is the first time I’ve noticed you even mention training apprentices. If you’re using our containment methods in the US I’d be interested to know how the NEC inspectors rate our methods.

BTW in anticipation I took a screen shot of my deleted post “just in case”.
 
As my question has been deleted

Yesterday was obviously delete post Saturday one of mine disappeared in another thread why is it non of the mods have the common courtesy to PM the reason why?

They haven’t got time because they’re to busy deleting posts.

The last time I had a post deleted I was sent a PM which stated the moderator hadn’t the time to read the entire thread. My response was not having time to do a job properly was no excuse for taking unwarranted action. I did get an apology.

Tony, you and I both know that this post is not the same as the one that I deleted. By the way there was a reason left in the thread.

UNG unfortunately it's become a daily occurrence to have to edit or remove posts. I personally could not justify the time to PM everytime I edit a post as today I would say I've had to moderate at least 50 posts. Every modification has been left with a reason on the thread.

Want me to post the screen shot of the deleted post? E-mails would be safer, you can’t censor them.

This guy has consistently belittled the UK electrical trade although not in the UK. I can assure everyone the US is no role model.
 
I think we all know the US is no role model for electrical safety, I've heard it said a few times that they are about 20 years behind is in it!

No need to email it to me. If you really want I'll put it up in the 3K club, then you can explain how it's the same post.
