Does this seem a little abnormal to you?





The HV lines come from the pole to a bracket with insulators mounted on the parapet of this building. Transformer is on the roof.

The secondaries come out the other side of the building (at far left). You can see 2 service risers, one in PVC conduit, the other in white SCH40 PVC water pipe.

Depends what country this is in.

Judging from the colors of the buildings & the "rojo" on the ad at the top of the building. I'd say this is someplace south of the US border... (Mexico, Central or South America) From what I've seen down there... ANYTHING goes!

No secret, it's in Mexico.
So, disregarding the plumbing pipe for a mast, does anyone ever see an overhead service to a building done like this?
I'm serious. I put up what I thought was an example of a strange way to do an underground service on another thread and found that it's just the way Easterners do them (and so do the utilities in Mexico)...S

I’m guessing ~35kV, but that seems a bit unusual for a liquor store. In the US, a unit substation on a roof would more typically be found on an industrial occupancy.

I did an EE set for a Bank T.I. in Westchester (1 mile from LAX Airport), and the original building (shell) was to have a setup similar to this - which was to be performed during a previously done remodel and addition to the entire building.

These plans were dated 1976, and the pages I am referring to were designed per LADWP Design Engineer's requests.

Was to have a Delta - Delta 750 KVA Transformer on the Roof, fed from overhead 13,200 VAC Primary Feeders to a dead-end rack.

I guess they scrapped these plans, and put everything underground instead.

It was a real eye catcher! Had to look three times at the Plan Page to make sure it was showing this!

All the Buildings in this area have the same model# GTE / Sylvania Gear (Main Breaker in the Pull Section, 800 amp rated multi meter sections, Federal Circuit Breakers, 1Ø 3 Wire).
Roof mounted HVAC equipment carries the wild phase and ends the grounded conductor at the service equipment - also located on roof / 2nd floor.
