    What is this? Saturday pic

    This is on the end of an old train terminal building. The box on the right is spliced directly into the service drop for the building. The weather head, on the left, feeds a 240 volt single phase meter. The conduit from the box on the right goes into the ground. It is not connected to the meter at any point. If you look close, you can see a piece of either UF or NM cable hanging out the bottom. There is a door in front with a wing nut on the left and hinges on the right. Whoever was in there last clamped the door over the cable.



    Using Photoshop, I was able to filter through the paint and read what was on the cover. It reads:

    Squared D Inc.
    Chicago, IL U.S.A.
    (Old building block style 'D' logo)
    The letters 'FF' in a diamond logo
    Condulet
    Pat. Issued and pending.

    All the above are in all caps and covered with a thick coat of paint.

    The conductors, cloth covered, enter the box through tube type bushings.

    Has anyone ever seen anything like this? If so, what is it and WHY is it on the line side of the meter with no fuse, breaker or disco?

    To me, this thing looks dangerous as the old conductors to the box are spliced in and hot. The meter below, a digital CL 200 was on and running.

    my money would be on a lightning arrestor
    At my age, I'm accustomed to restaurants asking me to pay in advance, but now my bank has started sending me their calendar one month at a time.

      I agree..... Although i have never seen one that was piped. What is in the conduit coming out of the box and what does it connect to.
      They say I shot a man named Gray and took his wife to Italy
      She inherited a million bucks and when she died it came to me
      I can't help it if I'm lucky

        RMC and just goes into the ground. I haven't a clue as to where.

          Augie, that thing looks like it may be 150 yrs old. Did they have lightning back then?

            I suspect it is a ground connected to a rod??? but have never seen it done that way.

                Good one Bob.

                Sorry Gus, but that was funny

                    Same here, I guess a lightning arrestor with ground wire in conduit to ground. Dig down, probably find ground rod or re bar connection.
                    Yes, I'll be happy to do a first class job for less than anyone else and take a dollar a week for 10 years.

                      Could it be a street lighting controller ? probably redundant.
                      Here in the UK some older street lighting installations used "ripple control" to switch the lamps throughout a district.
                      A signal at a few times line frequency was superimposed on the POCO network.
                      Each street lamp or small group of lamps would have a controller containing a tuned circuit that would detect this signal and use it to operate a relay or contactor, thereby switching the lamps.
                      It was a popular system before cheap reliable photocells.
                      Although mainly intended for public lighting, anyone could purchase a controller and use it to switch outdoor lighting in say a factory yard, railway station or parking lot.
                      If controlling public street lighting, the controller would be connected to the line side of the KWH meter.
                      If controlling outdoor lighting on private property the controller would be wired on the load side of the meter.
                      The box would contain a fuse, the tuned circuit, and a latching relay or contactor.

                      This system is still used in central London today ! unlike a photocell for each lamp it has the merit of central control.
                      It is a simple matter to light the lamps in daylight so as to check that they work, or to turn them off at night if required for filming.
                      Several different coded signals are available so as to give different switching times for general lighting, road signs, and seasonal lighting for example.
                      Turning alternate lamps off at midnight is easily achieved.

                      In the UK the equipment is made by THORN LIGHTING under the name "CYCLOCONTROL"

                          Cool! I didn't know power line carrier technology was that old, we have used something similar in the states to control indoor lights for light harvesting, but it didn't work so well. Most of the ststems I know of have been disabled.

                            Are there any load conductors coming out of the meter. To me it looks like an old weather head from when the service was metered elseware.

                            They then installed a modern meter, ran the service conductors down to the meter than back up the same conduit to feed the original weather head. The conduit from the old weather head may feed the building.

                            Have seen simlar wierd things when the area went to underground services, they then came out of the ground ran up the side of the building and feed the original weather head

                              IIRC, there is a conduit coming out of the meter socket on the bottom with an LB going into the building. I may be over there again today. My CF card filled up when I was there earlier so I didn't get pics of the meter and further down.

                              The conduit coming out of the old 'condulet' angles a bit away from the building before it goes underground.

                              I'll try to get more pics today.
