Tank Circuit Wire...

Hi all,

In my continuing quest as an internal packrat, I came across some rather large
wire (cable), and wanted to know if it was suitable for primary tank circuit
wiring.  This is the only thing I could find out about the wire itself:

        2/0 AWG
        325 strands/parellel
        Diameter of Conductor: 0.269" (copper)
        Insulator Build:  0.094" (94mil)
        Rated Current:  298A

Someone also told me it looked like Locomotive cable...what ever that is.

Any comments or opinions???
