It is a power cable of some sort.

Or a ground cable of some sort

Something you found in your wife's nightstand?

MI cable for a nuke plant?

A heavy cable looking to be sheathed in coper pipe, I have no idea what that would be used for but it looks pretty skookum!

Yup, that there is a chunk of MI cable I think..

4/0 conductors?

Google image search says it's a watch.

What ever is, it doesn't look cheap.

I thought it might be a plate of cookies. maybe I'm just hungry.

The coil from Willie Nelsons weed atomizer

The cable is Vitalink MC cable. VITALink MC Power Cables | Omni Cable

It is spec'ed for a 2 hr fire rating. We are using it to feed power to new fire suppression pumps in the Port Authority Bus Garage in Manhattan. Over $200 per foot. There is about 1500 feet being run. I can't wait to scrap the waste!

Nice! I've done plenty of big MC cable, but its all had a corrugated aluminum jacket when it gets that big. Is there a PVC coating on that?

IIRC the phone company used to call that "2 pair".

Get with Mr. Holloway. I'm picturing thin slices for use as coasters.

Thanks for the post.... I'd typically see a pump feed underground but in this case I guess no. What's 1500 ft doing to your ampacity ?
I inspect for a living but sparky stuff is my weak point...

Clue us clueless ones a little more on the scope. Feed size A, pump requirement at 100+ percent etc

I do like California Rolls!

U fkin beat me to it....

The pumps are;

100hp 3Ph
3500 RPM
750 GPM at 335' TDH
460V
400 amps

All cable is exposed.

There are 4 pumps and the need to push A LOT of water.

Why is the copper shielding left exposed? seems it would be a green corroded mess in short order.
