Labor For Pulling Feeders

[Alwayslearningelec]

I am running feeders free air on wood poles. I would imagine it is a labor saving to get a cable(3 hots & Nuetral) in ONE cable rather than paralleled. You would be pulling 4 separate cables instead of 1. Is that the correct thinking? Thanks.

You say feeder yet do not mention an EGC. What type of multi-conductor cable are you thinking of using? Have you looked at 225?

It is correct thinking. How else are you going to support the individual wires. You want to run quadraplex just like the power company would. I assume these feeders are going to feed buildings or some type of structure that will be served by these feeders. The end or ends of each feeder will be a service drop I assume? Just think about how the POCO would do it?

Thisn is what I got from my guy. But I think I need a neutral, my engineer said I can use the messenger as a ground. not sure if that is correct. So I just want to understand this correctly. The attached is like pulling ONE cable and the other option is to pull each phase separatly( or do you pull them together even though they are separate?) Thanks.

The bare messenger is the neutral. You don't need a grounding conductor if these feeders are really service drops to structures. It's just like any feed to any service. If you need a grounding conductor you haven't said why.

Yes the attached is one cable assembly. It comes on one spool. Pulling secondary wires individually on a pole line is pretty much unheard of.

Thank very much MKGrady, that was helpful. I will be using these cables to run overghead and feed 400A panels mounted outdoor on a wood type of structure we will build. We may run from there to feede many trailers near by. What would determine whether or not I would need a ground?

If you are under the 08 NEC the word feeder.

Sorry Roger, I don't understand what you mean.

Sorry Roger, I don't understand what you mean.

As Mkgrady touched on, you need to clarrify whether these are services or feeders. A service drop would not need an EGC whereas a feeder would under the 2008 and possibly under earlier codes if there are grounded systems that could create a parallel neutral path.

If they are feeders, 250.32 is the article you would need to read.

Got it! Sorry, but where can I read as to what determines either a "feeder" or "service drop"? Thank VERY much for your insight.

 

[Alwayslearningelec]

Well I just thought about it. if I am gogin from distribution boards to panels that has to be a feeder not a SD

 

[roger]

Correct.

Thanks Roger

You're welcome.
