Actually this type of information with diagrams and how to check electrical wiring inside pedestals or for that matter any electric wiring done by persons that do not know anything about the dangers posed by the electrocution potential is down right dumb and irresponsible, think of the heart surgeon that is now retired and gets hold of this information.
So the doctor goes to Harbor Freight and purchases a meter for $4.99, (by the way my meter cost a little more than $400.00 Dollars} it looks just like the one on the picture, then he also purchases some screw drivers and some pliers (no insulation) that the clerk pointed him out, then he goes checking pedestals after a good rain, he can do this he's an open heart surgeon he has the pretty pictures with color to guide him and he has the little gismo to check with black and red wires, not different from checking a heart and veins, heck it is a piece of cake.
Coroners report: Doctor electrocuted while messing with RV park's electric pedestal.
