Bus Support for IPS
Bus Support for IPS
(OP)
I was wondering if the connection shown in the drawing below,(two welded four hole connectors) would be considered a suitable bus support for the smaller IPS span? Larger Aluminum IPS span is 17" the smaller span is 12.5'. I've only considered insulators, S.A.'s, switches, bushings... as sufficient support for an IPS run. I've never seen this done.\
Thanks,
Thanks,

I assume you mean the the larger span is 17' not 17".

I agree with you. I don't like supporting a piece of IPS with another piece of IPS that, in turn, is being supported by two switches. I would modify the structure to include a bus insulator either supported from the vertical disconnect switch steel support or add a cross member to the 'A' frame structure to mount the insulator to. My opinion...

Expansion is addressed by the two bends.
The longer vertical span would be at more risk of deformation from a short circuit than the short one.
