SEU Riser

[jwjrw]

I know they make you use the 60deg column when se cable is ran inside a dwelling. So there is no problem using the 75deg column for a riser outside correct?

no problem, and if it's a service don't forget the advantage of 310.15(B)(6)

If you can use 310.15(B)(6) instead of 310.16 your wallet gets fatter.

Which allows me to use 4/0 al at 200 amps while 310.16 says only 180amps correct? The way Gus worded his post made me think I missed something.

And not just a service, but the main power feeder.

As in a back to back installation correct.

As in (B)(6) can be used on both the line and load side of the disconnect, as long as those conductors serve 100% percent of the load.

Yes and as in a feeder that may run 100s of feet to a subpanel as long as that sub panel supplies the entire load of the dwelling.

You could have a meter / main breaker combo outside and use 310.16(B)(6) to size the feeder that runs from there into the panel.

Gotcha. I had it right but wanted to make sure. Its going to be cheaper to run SE instead of 2" rigid thru roof.
