Hello Peter PJB
You got 12 REPLIES - of the 247 views - on your original EL Wiring Thread over at Subways - including my extensive final one with photos (see link to it below) and my basic explanations of modeling power feeders as per done on the prototype. You did not even reply to my posted info.

How about POSTING some PHOTOS of what you already have built (your "EL") so we can see your progress.
ALL the real EL's have their feeder and communication and electrical (lighting, stations, signaling, power feeders, etc.,) strung along the EL STRUCTURES from point of entry (either coming up EL columns or from line-side substations via connecting cable bridges from them over to the El structure) running along the structures attached to insulated hangers usually located along and attached to the outer most track girder of the outer local tracks. Some minor wiring systems are strung along the outside lower portion of the catwalk railing support stanchions ! Some are also alternately hung via brackets attached to the outer edges of the long catwalk ties - or/and from brackets attached to the sides of track girders (see SECOND PHOTO) and strung outside of the catwalk railing area !
SEE 4 PHOTOS I PROVIDED BELOW of various samples of above feeder-cable-stringing.
These same procedures could be done on model EL's. I have done some of it, and a very few others who have modeled EL lines have done it - including wiring for track blocks and power feeds.
So I suggest that your majority of wiring comes up to your EL from one or more trackside substations (like my own model photo and Album of my substation) - and connect to your EL via a cable bridge. Other wiring can come up certain El columns from "under the street" to where they would be attached near to, accessories, along the trackside.
Building a "fully scale" appearing and functioning "open deck" EL line with trackwork in ie: HO or O Scale - including wiring it properly for signals, lights (stations, etc.,), block circuits and power feeds), and using prototype wiring methods and systems - even if a bit modified for the model applications - -- is a very skilled and tedious specialized "architectural" engineering form of "trestle and bridge" format modeling, likened to also building by hand, steel-modeled long scale trestles and bridges.
I have done it - and been doing it for 50 years now - in both my earlier HO Scale Modular EL System (32 x 8 foot system) and present O-Scale Modular EL System (40 x 8 foot system). And there are very, very few known of us in the hobby who have actually built and modeled scale appearing and functioning realistic EL Systems.
What I have provided, and those other responders did, is basically correct.
