Here in New York, I ran across something similar in front of a chiropractor's office.

This is conduit going into a round out-door type junction box. Then from there you have Greenfield (coated with gray plastic) going to the illuminated awning.

The connector from the Greenfield to the box has slipped out (lock nut got loose or missing?) and now it's swaying in the breeze dangling from the wires much like the top pipe in that electric meter picture.

I will have to take a picture and send it to you in the US Mail since I don't have a scanner to email it to you.

P.S.: Is the utility pole made of concrete w/rebar? Looks similar to the types of poles used by telephone and electrical companies in Colombia (those are made of rebar framework with concrete).

Greenfield (coated with gray plastic) ----- is probably LFMC Liquidtight Flexible Metal Conduit.

I too have a similar image. If you can take a digital image and email it to me, I can post it here. If not I will look for one that may help to generate more discussion.

I don't really have an answer to the pole question you ask, if I do go back and I will sometime soon to San Diego, I will take the trolly into that bordertown near Tujuwanna and take another picture.

joe.can you tell me do they meter the street lighting in mexico? just asking.i know i starting seeing meters on poles around some schools on there signs,speed limit more free electric.

i also see a pad lock on the meter,that something you don't see here in the united states.barrel lock or seal yes.padlock no

it look like a seal tite connector in the bottom of the panel,but the wiring looks to be romex or uf cable with romex connectors on the fact i don't even see a ground wire.looks to be a steel pole. and the hole in the pole looks to be 3/4 for the open wiring on the top of the meter.what can i say. it's a accident waiting to happen.either someone with a truck hit the meter or the screws rotted out.

Is there only one wire there running through the conduit into the meter?

I don't remember, but the meter socket enclosure was on a pole at the corner. I was being observed by some local people, and they must have wondered why I was taking the picture!

It probably was a zip cord going into the top. Zip cord is not uncommon in these streets.

The traffic light -- I don't need no stinkin traffic light!

I will search my archives, because I may have another picture from another angle.

In the meantime the wires may have been removed (stolen) so they could be turned into cash!

All too often, boxes are damaged after being backed into by a truck, hit by a forklift, etc. Only once have I ever seen something done about it...
When Eagle ( now part of Lowes) was building their second "box" store here, the layout was almost identical to the first store. One difference, of which I heartily approve is that in this store, they had "ears" of 1/4" steel welded to the posts on either side of the outlet, phone, or what-have-you that was mounted on the post.
The code does reference protecting things from mechanical damage. I'd like AHJ's to see this sort of damage as proof that additional protection is needed.

NEMA makes reference to this in OS 3-2002 on page 24:

NEMA OS 3-2002, 2.3.2 Surface Mounting on Walls or Ceilings

... Placement of surface mounted boxes should take the exposure to possible physical damage into consideration. For instance, placing the box in the U-shaped channel portion of an I-beam would provide more protection than mounting it to the exposed surface of the flange (See Figure 1, Pole Mount-Protected).

Damn, now that sounds like "common sense" one way, and "job(work) security" the other.
