    well you got one of those problems that really doesn't have an answer, since the only legal way to open that switch board is to have it shut down, but then this kind of defeats the IR scanning...

    You should be able to get the info from the inside of the canopy and or on the LV transformer, it has been a few years since I installed one but they were popular around here for a while, I believe...

    I got to back up a little, someone also thought of this problem as 404.8(C) clearly doesn't allow it:



    wonder if they are listed as a two circuit device??

    There is no restriction on switching a 277 volt load with a 277 volt rated switch, like I said it is the voltage that will be interrupted by the contacts when opened that the rating is for.

    You...

    The voltage rating is the voltage that the contacts has to interrupt, on a 277 volt load you will have 277 volts across the contacts when the switch is opened, if you put the switch on a 480 volt...

    you must keep in mind that the voltage drop on electrode connection to earth is only a few feet around the electrode, once you get to a point of about 26feet there is no more voltage drop, think of...

    Here is another example that most would not pick up on in the sweep you posted.

    Take a look at the scale on the left in that scan, the voltage in in blue and the red is the current pulses from the...

    I have read this doc a few years ago, and it is correct that allot of current does flow in the earth, many years ago I proved a point that our low frequency power current can be sensed around the...
