Just extend the conduit so's the empty lands by her TV chair. Or hit's her in the head to get her attention. Probbly better stick with the chair one.
Aluminum is perfectly fine to use for the larger amperage services. Copper is almost done for above #4 (both arm's & a leg). Just be sure and use some of the gray dielectric goop (has many names Nolox,Nylox,Purox,just kidding on the last one).
Most all the service drops from the pole are Aluminum.
I would NEVER use it for circuit wiring.
Only question on using the 100A. in the house box is,
What size SERVICE you got now?
Hopefully a 200A cause IF you only have a 100-150A you got a problem.
Or, Just use the Quote box above where your posting right above the "Enhanced Mode" button. It's the last one on the right, look's like a piece of notebook paper.
