Anybody ever heard or seen this wire?
It is about the size of 350kcmil. Aluminum stranded wire with a jacket similiar to XLP.

The customer told me they bought it from some supplier in Fla. I am a bit suspicious. We are in Pa witha multitude of electric supply houses. I suspect this wire is from another country. The tenants (commercial) are Russian, and "scientists" scary!!!
They are designing a new way to make glass. Anyway, anybody on the wire??

Is it listed in Table 310.13?

I doubt it, and if it's not in 310.13 it can not be used.

336 kcmil sounds like it's PoCo wire.

336 is a common size for utility use...as is 636, 795, 1113.

I took a better look at it today. It appears to me to be a multi cable with an outer jacket. Similiar to SER.
It the grounding conductor they used has no insulation, again like SE or SER cable.
It is hung over the drop ceiling with rope and it is twisted. I am sure they didnt twist it either. The individual conductor has this stamped in the insulation 'CME WIRE 600V 336,4 KCM XLPE BRONCO'
XLPE is not listed in the code book.
I am prepared to tell this tenant it has to be replaced with the correct rated wire. I just wanted to make sure I am correct and to be able to back it up withthe correct wording, and show them in the code book.

"Bronco" is kind of a code name for a type of triplex or quadruplex we use out in the oilfields for 480V overhead linework. CME is a UL listed mfr., with most, if not all it's products made south of the border (Their romex says "Proudly made in North America [Linked Image] )

here's a link http://www.cmewire.com/products/ix600sdc.asp

Funny though... they list the 336.4 as "NannyNose" [Linked Image]

BTW... I dont think this is made for in the home use

XLPE = cross-linked polyethylene.

XLPE cables tend to be very good for outdoor use, especially for HV, but if you intend to use such a cable indoors you need to double check the fire rating. XLPE burns very well unless the manufacturer has added some kind of flame retardant.
