Would you install these? I wouldn't, and here is why:

  1. No place for grounding prong for three-prong cords
  2. Too easy for multiple line-line/neutral-neutral/line-neutral shorts, especially on the vertical runs
  3. Existing solutions to the problem it purports to solve without introducing new dangers (such as this squid outlet multiplier)
  4. Doesn't appear to be tamper-resistant

I cannot see this getting UL approval without at least a modification to add in a row for grounding prongs.

Thoughts?

It also doesn't look like it's tamper-resistant, so even if it does get UL approval, you won't be able to install them anywhere in a residence, except high up on a wall.
I didn't even catch that, I'll be adding it to my own list.

That may be, but the website I linked to seems to advocate users should try and purchase them if they can navigate the Japanese menus. I have no doubt that eventually we could see something like that making large in-roads in the U.S. It looks easy, it's stylish (in a minimalist sort of way) and adds a huge level of convenience.

"Fitting fine" is the issue... What is in place to make sure that a polarized plug cannot be installed in a fashion in which the polarity would be reversed?

Pete
I don't see how polarity is an issue in A/C motors, honestly. Even with the cord going to a rectifier pack (such as on my laptop) A/C polarity is a non-issue. FWIW, the cord on my charge cord for my laptop is non-polarized.

I've never really understood the need for polarized cords, honestly.

It sure will if the ground ever becomes faulty now you have an energized chassis and a shock hazard.
I understand the need for a hot line and a neutral line in the power system, but in the cord itself? Pointless.

Edit: If the neutral part of the cord is somehow bonded to the chassis, I could see the point then, but then why not just use a three-prong cord and be done with it? Wasn't that part of the impetus for dryers going to a four-wire cord (e.g. separating the neutral and ground prongs)?

Also, energized chassis only applies if contact surfaces are metal (such as with my toaster oven). If the chassis of my laptop ever gets energized, I have bigger problems then a faulty ground.
