i'm doing it anyways, but....


when i get to the elec. pole end of this home i'm building, i planned on removing the aluminum wires from the pole/meter breaker box and putting in copper and doing better ground rods as well. i'm doing it anyways, but.... since i'm removing a trailer/mobile from inside to do the 'stickbuilt', ( i hate that term) wouldn't i be required to use copper anyways? just curious....

No, copper is not required. Aluminum is fine.

as to "better ground rods":

your grounding electrode system must be installed properly. Ground rods are actually not required IF other systems are in place but often installed to appease the inspector or make his job easier.

In a new foundation, you must utilize a Ufer ground (foundation rebar; falls under the concrete encases electrodes in the code) if there is one there. You also have to bond to the water pipe, if it meets requirements.

No, Copper or Aluminum is fine for the service. When you say "get to the pole" what do you mean? The conductors that leave the utility transformer and enter your meter or service mast belong to the utility. This is called the service lateral. You have no way to shut this power off. They must do it.

Aluminum is what is used in most every case. The utility will use it for the lateral. It is much more economical for you to use it for the service entrance conductors. These belong to you. The conductors that leave the meter enclosure.
You can use either AL or CU.

jv, elec. and plumbing is on the back portion of the home, i will do that last. i'd heard that AL corrodes after a while, and i also thought it was only for mobiles? think i read that here somewheres.... heck, if it's still ok, i'll just move the inlet pipes i laid and reposition the BBox! i did it all myself, and used all the right stuff. anti-corrode gray goop, etc.

It will only corrode of no anti oxident is applied. It could also happen if it does not cover all of the exposed wire.
