(3) temporary poles, (1) service - do they each need a ground rod?

225.32 is using an Article 100-defined word. A word defined in 100 is universal throughout the NEC.

If a pole is a structure when we're discussing a disconnecting means, then it is also a structure when we're discussing grounding, because "structure" is a universal word in the NEC, IMO.

The words temporay pole are still not mentioned in 225.32.

Also the word "stucture" has only been defined in the NEC since 2002. Since prior to that we had to define it ourselfs we chose to decide that a temp power pole is not a structure. If that were the case then any stantchion you built and attached outlets to in the middle of a plant would require the installation of a ground rod.

I would be more likely to say that temp power poles fall under 250.54.

You can throw all the logic you want at this, but until the definition of structure is changed or the other rules are changed to exempt some structures we are stuck with the fact that everything is a structure and if fed by a feeder or multiple branch circuits, a grounding electrode is required.

I didn't say I was being logical, I was just arguing. :wink:

Well I believe the bonding [parallel] is between the service side and the demarcation. I?m not positive if serving phone/coaxial bonds to an electrode in it?s service route, but it does bond to the electrode system at the building [demarcation]. So if the phone/coaxial service bonds before the demarcation it will be a parallel neutral path and it will be a very good one if they bond to the same electrode as utility power.

As I understand it, this is true - which is why phone demarcs tend to get damaged during open neutral events.

...but if a residence has its service disconnect on a pole ? remote from the home ? this situation will most likely happen.

I beg to differ. My home's service disconnect is on a pole over 300' from the house's main disconnecting means. There is a ground rod at the service disconnect, and there is a water pipe electrode and a ground rod at the house. I don't see a snowball's chance of there ever being a parallel metallic neutral path between the service disconnect and the house.

We?re on the same page George and I appreciate your energy on this site.

Well, I'm about wore out on this one. Have a good Friday and an excellent weekend.

Does your phone/cable service come from your power service pole? If it does then it?s supposed to be bonded there and again at the residence ? hence parallel.

Wore out Ha!
