[RE-wrenches] Grounding system for a shack on a frozen lake?

[Drake]

I think the system would be technically required to have an equipment 
grounding conductor to connect to lighting fixtures made of 
conductive material.   I believe this is true regardless of voltage. 
If these do not exist, and no metal boxes are in the system and it is 
only 12 V, then it might be compliant to exclude the ground.  If it 
is only a 12 volt system, I don't believe there is much danger, 
unless the person has a pacemaker and goes barefoot on the ice.

410.46 Methods of Grounding.
Luminaires and equipment shall be mechanically connected to an 
equipment grounding conductor as specified in 250.118 and sized in 
accordance with 250.122.
