Got it, had it for a long time :) My grandfather was a DFL for many years.

Of course, thats a given

hot gloves are a nice option here,

Got a nice set (my 3rd, I replace them every 2 years) of the Gauntlets. 
Leather outer, then yellow, then orange, then something that may once have 
been a sheep. Standard issue for Consumers Energy (our local power concern)

A Wiggins? Vibrating voltage probe? Got one.


don't ever try reading the hv side unless you have the

No fear mongering there, good common sence. I firmly hold true to the same 
school of thought. You don't get a second chance with HV. I heard an old
