    I disagree on one fine point, NEC requires every wire
in any conduit or enclosure be insulated to the level of
the highest Voltage, so if there is 480 Volts in an
enclosure, the meter and other small signal wire needs
to be insulated for 600 Volts which many MFG. fail to do.
   Carried to the ridiculous, if the plate Voltage is 6 kV
all wires in all conduits & enclosure need to be
insulated for 10 or 15 kV.  I've never seen that.
   This is a dependability not a safety rule.

         Youvan's corollary:  Every action results in
                              an unwanted side effect.
