[RE-wrenches] Disconnect BOTH positive and negative conductors from array?!?

[Kent Osterberg]

See 690.13. There must be a means to disconnect all conductors of a PV 
system. If it is a normally grounded array you are not allowed to put a 
switch in the grounded conductor, except .... for circumstances added in 
the 2011 code.
