Building a Power Strip, any advise?

Ozzy,

There are some very good A/V power strips out there. Admittedly, they are usually overpriced.

Hopefully you have never had to, or never will, make a insurance claim for a home fire. But once you have been through the nightmare that most insurance company investigators and claims depts. put you through, I guarantee that you would never condone the use of any non-UL approved device in your home. These folks are looking for any excuse to deny all or part of your claim, and the use of any type of non-UL product attached to AC power will cost you orders of magnitude more than just buying the approved product.

Leave enough space for oversized wall warts.

Thanks everyone for the comments.
Br3098, since I have many hi end power cords that are not UL approved I guess I have already crossed that line.

Elizabeth, it sounds like I do have the same wire, thanks for the approval. That is my plan to try various outlets.

Unsound, I hear ya about those pesky wall warts but at this time they need not apply. The Junction boxes that I have ordered are of a heavy grade aluminum that already has cut outs for the outlets and they will run perpendicular to the power strip.

Elizabeth, I'm trying to understand your quad twist. Are you saying you are using 4 12 ga wires that are twisted together and then connected to each connection on the outlet? If so, wouldn't that be like a 3 ga aggregate and how the heck would you connect that much wire to an outlet?
I must be missing something.
