School not to far away, had it's service(s) burn up. $750K to $1M damage.

Will be interesting to hear more details on that one. Janitor commented the equipment was "Red Hot" when they showed up for work. Two 4160 feeds and both were glowing.

Is there an NEC rule that specifically states services shall not glow? :grin:

Designed replacement for one that had similar outcome several years ago.
Primary fuses replaced with EMT. Underground utility locater (backhoe) found 200 amp feeder to the welding shop. Big holes in the bus bar from the arc.

Good luck!

That's the problem when you use the wrong size EMT !

determination of the cause, low bidder:

More likely lack of maintenance and testing.

Augie
I was under the impression that utility companies do not use EMT for primary fuses...I always thought that when changing out their fuses, copper piping was the minimum permitted... :grin:



Let me show you

These are good for standard NEC applications

These are good for NESC - utilities.








For any who may not realize, I am just making fun. These are not premitted installations.

low bidder for maintainance and testing ?
