I know it's over, but I just replaced an outlet and decided to take a picture of my electrical tools.

The continuity tester on the left never gets used but it was in the bag.
I keep a box of wire nuts and those plastic push connectors. I'm not sure how well they hold up, but a lot of my boxes have very little extra wire and they fit in better than nuts.
Utility knife
Dikes (The linesman's pliers can cut also so they are a bit redundant.
Needlenosed pliers (handy but less important than linesmans)
Linesman's Pliers (most used tool after the screwdrivers)
Outlet tester (not required but it checks ground and polarity and is cheap. This one was free)
Wire strippers (this kind is my favorite, but there are cheaper ones and you
can strip with the knife or dikes if you are careful and don't nick the wire)
Zip ties!
Top right is my flashlight
Screwdrivers, one phillips, one straight. These are Klein wire bending, they have a lug on the handle that lets you loop the wire perfectly for screwing onto the terminal. Don't even need pliers.
The silver thing is a sheath ripper.
The pen looking thing is a voltalert. It tells you if a line has juice without actually touching a wire. It also lets you know if an outlet is hot and if the polarization is correct.
