Installation details [RE-wrenches]

Max,

We have been doing this on all multiple Sunny Boy installs, very 
clean. Per a C-10 who has done lots of commercial work for me, the 
mixing of various voltages of AC & DC (eg. 48 or 300 VDC, 120 or 240 
VAC) in the same can is OK as long as the insulation on the wire used 
has the same rating. For example as long as you use THHN 600 volt, 
105 deg. C rated wire for everything it's OK.

Any codemeisters want to take a shot at this one?

Regards,
David Henry

>Graham, I was looking at the layout for the 2500's. It appears that they are
