Ag wiring

[ptonsparky]

How many can you count?


Brand new. I’m here to put in an injector pump receptacle.

Ag is the symbol for "Gold" on the periodic table of elements.

Looking closely at you images for gold wiring, but don't see any?

Actually, Au is gold. Ag is silver (Argentum). But I cannot recognize silver wire under the insulation.

Gold is Au symbol 79

to slow..

Except for the fact that it tarnishes, silver is supposedly a better conductor than copper... Gold is nice because it doesn't tarnish. Of course, Gold has to be alloyed with other metals because gold is lousy in mechanical properties (relatively speaking).

I should have asked how many NEC violations.

I should have asked how many NEC violations.

Had to save images, and enlarge using image software.

1) Direct buried cables protruding above ground without raceway protection.
2) Custom controls cabinet not listed, or field approved
3) Cabinet raceway missing thread bushings
4) Don't see grounding bus for green wires

Can someone explain those strange looking 2-wire connectors?

Since you didn’t give us a full picture, there is probably more, doubled up wires on the starter, feeding the panel on the other side? Service conduit too short, can’t see where the spliced utility feed goes.

They changed from Al to Cu. Eaton doesn't care though.

 

[hillbilly1]

The two wire connectors appear to be Polaris type splices?

You know it could not be that simple here!

 

[ptonsparky]

The black raceway is Cable con sleeved into what I would call a Mernards expansion joint.

Yes.

The sealtight is all ez flex. 480V. The 10' of horizontal pvc is sched 80.

 

[hillbilly1]

Looks like they put control wires into the splices too. The control wires are probably copper, and the feeder is aluminum. What could possibly go wrong there? LOL!

I think the main issue is what conductor types are still fairly conductive after they oxidize. Aluminum oxide not significantly conductive at all, copper not too bad and silver and gold presumably don't deteriorate to any significant amounts when oxidized, conductivity wise for most uses from my understanding.

ok

My best guess is service conductors are spliced, the other service "tap" goes to the "other panel" which is probably a control panel for a center pivot irrigation machine. Those control panels usually have a main fused disconnect within them but are not normally suitable for use as service equipment

Now with the additional pictures I know what the "other panel" is - it is basically a pump panel with some additional controls added by equipment manufacturer and it controls a hydraulic pump for a hydraulically driven center pivot. That style is usually suitable for use as service equipment, but the better picture looks like it is tapped from the load side of well disconnect and those two conductor splicers are just there because the incoming service lines were either too short and/or they wanted to change over to copper before landing on the disconnect within that pump panel. Many are not CU/AL lugs, don't know about Eaton, don't see many this area mostly SqD. Siemens I believe does accept aluminum though.

 

[ptonsparky]

That is a pump panel for the hydraulic motor. The Label on the door says the "System Disconnect" should be off and locked out before opening the door. Someone care to define that?

Ok, now I can see the control wires are just run behind the taps, not in them.
