15 Amp Commercial Grade Duplex Outlet, White

They are both code complient. Wrapping around screw head and tighting well takes a few more minutes an outlet but you never have a current flow condition.

No. You need a receptacle rated CO-ALR. As an aside, consider putting an AFCI breaker on any circuits with aluminum wire, this will detect arcing.

Yes

All the HD stores I have shopped in have the almond colored devices. Your must have been temporarily out of stock. Oh by the way, HD stocks these devices by color, sometimes in seperate locations in the same department. You can also order online with store pickup or home delivery.

No you can not . On top off that you should never wire a receptacle in a pass through configuration . There needs to be joints in the wire with tails feeding the receptacle .

NO. To install this device, you must have either an equipment ground wire (usually bare, sometimes green insulated) or the box must be metal AND grounded through the cable jacket (metal jacket such as BX or AC) or through metal raceway (conduit, EMT).

Yes, it will replace a two prong, however, to meet current code requirements you will need to run a ground wire to building ground... Also, the black wire will go to the hot side of the receptical and the white to the nuetral side. Ground to the green screw. Be sure to "bond" (connect) the receptical-ground to the metal box.

It does come with brown color, I saw it at home depot

no

The "double pole" feature on this outlet refers to the fact that you can run separate circuits on each receptacle. Each side of the outlet has two screws. They are connected by a common conductor. There is a small bridge that can be snipped out that allows each receptacle to be wired to a unique circuit if desired. That would allow something like an "always hot" lower receptacle and a switched upper receptacle. Most upper end outlets have this feature. What's really nice about this "Preferred" grade outlet is that it also has brass plates on the terminal screws that capture the wire and provide more surface area to keep the connection secure. You aren't just relying on the screw heads and the loop you put wire.
