[SML] Safety tip.

[Dale Farmer]

Hypothetically speaking, if you have an electrically powered device 
rigged over your stage from an outside artsy builder.  Make sure that 
the safety ground in the plug is actually connected to the metallic 
frame of the device, and the current carrying conductors are protected 
from damage.   Because, well, when the current shorts out to the 
structure, and the only path back to ground is via the wire rope holding 
it up.  The wire rope acts as a fusible link, and it's WLL goes to zero 
with a pop, followed moments later by a crash.

Just sayin.
