Double check before energizing!

Here's one for you!Apparently that superior level of skill and training union electricians and linemen are provided dosen't include knowing how to read!Yep,perhaps an unfair jab,too bad the truth will never be revealed to the poor power company customers who will be paying for this mistake for years to come...

It's not clear what the reporter meant when they wrote, "more powerful versions" of the transformers. I can only assume they had a higher output voltage than the originals. It does strike me odd that the output voltage wasn't checked after the transformers were hooked up but before the building was energized.

You know these things for a fact, or are you just speculating?

Primary / secondary windings markings reversed? Bad manufacturing, ie shorted windings.
Ya think they would have checked the secondary voltage before throwing the breaker into the building.

That's the frist thing you do before you put power on anything you put your meter on it and if it's fishy you check with another meter. What they did was hook up 480v to the building. simple as that

hey man even the best have bad days. it sounds to me like you have an axe to grind. i would bet that i don't have to go too far back in your history to find a similar mistake, it just so happens that this one is magnified by the circumstances.

Is Enmax union. Looking at their site, Looks like they do their own training???

Everyone fu*$s up once in awhile, even pro's, its how we learn, sometimes the f ups are expensive and unfortunately sometimes folks get hurt or killed. In this situation no one got hurt so the utility got lucky.

Im sure your publicly owned utility in Canada is still a helluva lot better then the corporate owned operations like AEP and XCEL here in the US.
