[RE-wrenches] Code "Authorities"

[Drake Chamberlin]

There are issues with some combiner boxes, when the fuse holders are 
opened under load.  The current can (reportedly) make a continuous 
arc across the contacts.  This is true for the higher voltages, for 
grid tie inverters, and would be true for AC coupled off grid 
systems.  Maybe 100 V would not be an issue.
