[RE-wrenches] DC positive and negative in same conduit, other inspection ...

[William Miller]

Don:

The DC feeder may have an AC component imposed on it by the switching in 
the inverter.  We installed a large Hawker battery bank 
(http://millersolar.com/Portfolio/Commercial/Cal_Trans/cal_trans_gorda.html) 
that physically vibrates under heavy charging.  We have also seen in this 
forum reports of RF interference from battery cables.
