On a service riser over head ,I ran to situations where I have to make my own KO for overhead riser is that UL listing violation I'm not using the premade hub in the center of panel I'm using a Myers and making my own Ko on top of panel sometimes on the left sometimes on the right these are service changes thank you
if you are changing out a service, and the old service (like zinsco) is centered,
and the new service (like everything else now) is off to one side....... and you
want to use the original hole in the roof.....
i've just bent an offset in a 10' stick of GRC, and changed it out.
you can measure the new panel, and the deviation from center,
and pre bend it. spin the listed hub onto it, and screw it to the
new can.
if that fails, you can always hack a hole in the center of the new can,
butcher the barrier, and void the UL listing...... :huh:
