    Default CT metering

    This looks to be a metering set up, but a very odd one as those current transformer(s) are often mounted inside cabinets and to lesser degrees the exterior wall.

    You will see a second weather head, so my guess that one goes the meter.

    Is that orange tape I see there? Is that one of those Delta connected oddball 3-phase systems we used to see more of out where they did not run three phases? Just curious.
