Xfrmr Conduits

[Alwayslearningelec]

Never came across this many, and this size, conduits landing in a xfrmr. Is it even possible(Obviously I assume)? Do they make 5" FMC? Thanks

No there is no 5" FMC but with transformer this size you would typically run the RMC right into it. Not sure why anyone would run 5" for those conductors.

4"is the largest FMC but you can't use FMC outside. I have never seen any type of flexible conduit used with a transformer of that size.
Also not sure why they specified 5" conduit. There is a huge jump in costs over 4" and five 600 kcmil fit in a 4"

What about the secondary side?

Imagine lb would be easier

You can't fit that wire in a standard LB. You will need a mogul one, and you need to make sure it is suitable for that wirefill.
