Low voltage/ high voltage clearance

[mudmanc4]

Working in an area which is confined, where a residential 200 AMP service fires a breaker panel, clearances for service are obvious, as the following diagram explains:

 

Where NEC 11.26(A)(2) states a 30" working / access clearance width (as wide as equipment or 30" whichever is greater)

Panel door hinge must open a minimum of 90 degrees.

I've placed low voltage equipment starting at the 30" mark to the right standing facing the panel.

However there are low voltage lines running within that 30" against the wall.

 

I'm being told (by the local electrical contractor) the door hinge on the breaker panel must swing out/  open 180 degrees, and no low voltage equipment can penetrate the 30" threshold.

 

So the ultimate question I have is what are the code(s) regarding low voltage clearances regarding a 200 AMP breaker panel. 

Or how far away does a low voltage line need to be from a high voltage box.
