Source of bus bars, wire and testing

[TMD]

Two questions regarding sources of supply:

1. Who supplies bus bars in North America? Seems like a common enough product, but finding it has proven to be non-trivial.

2. Who supplies hook-up wire, twisted pairs, coax, etc, in small sizes (less than 1.5 sq. mm) that have fire ratings like IEC 60331 and 60332? I'm looking for the European equivalent of Belden or Alpha.

3. Lastly, any high power (35 kV,650 A) test labs on the east coast of the US? I've found two in Canada (IREQ and Kinectrics (and Powertech on the west coast)).

1. You can buy Copper bus bars from any electrical house like Graybar or G.E. Supply or Wesco.
2. Try Anixter Wire & Cable, if anybody can, they can.
3. Contact G.E. Industrial Services. Does it have to be in the West coast. Westinghouse Field Services has offices everywhere.

As far as qualified testing companies, if you seek someone on the east coast who is independent of the manufacturers:

On item 3, although not east coast, these guys may do.

There’s the EPRI Lab in Lenox, MA, but they seem to be limited to HV insulation—limited current capability.

Thanks for the information. For anyone else following this thread now or in future, a few more test labs:

European wire is hard to find. Anixter has been of limited use: they usually end up quoting North American equivalents.
