grounds [RE-wrenches]

Travis,
To be totally code compliant, you would have to ground all your metal 
boxes (equipment grounds), but not necessarily the negative leg of 
the system. Two wire DC circuits below 50V need not be grounded. 
However, elsewhere in the code it says that you need a over current 
device in ALL ungrounded conductors. Wiles and company (the Code 
Fundamentalists) interpret that to mean a fuse or CB in both the 
positive and negative wires. Ridiculous? Certainly. Stupidity? 
Depends on who you talk to. I think so.
