Wow!!

[Garry Sorrells]

Had not seen that Utube before. Interesting.
But, if plastic box the Fluke should light up on last test.
It may be wrong in stating that the box is hot when in fact it is the outlet connection to the box that is hot by way of it being grounded through he outlet. (bad phrasing, hope you get point).

Mike Holt posted this on his site, so I assume that it has been properly vetted.;)

[John Kogel]

Does Mike Holt approve having the receptacles upside down like that? Tsk, tsk. :D

[Donald Farrell]

John,

There is no proibition to mounting the receptacles with the ground facing up. In fact there is a school of thyought that validates that type of installation. I don't particulary buy into it myself, but here it is:

If the receptacle faceplate were to work it's way loose (I've never seen that happen), and the faceplate happens to be metal, then the first thing the face plate would hit is the ground pin.

I hope it was not vetted by Mike Holt as it contains statements saying things are safe when they are not.

Take it up with Mike Holt.

Don't need to ... *I* will not *assume* that it was vetted by Mike Holt. :)

If it is reversed polarity and boot-legged, that means the outlet back strap, screw and most all conductive components, ( except for the parts that should be hot ), are hot.

Yeppers.

And, if it is in a condo (or house) with metal frame stud walls ... *all* of the metal framing which is continuous with that metal box is also now energized.

If newer construction, the metal studs would be grounded, that should trip the breaker. However, older metal stud construction did not have the metal studs grounded and all of the walls could be 'hot'.

Very informative

[Matt Kiefer]

I will be adding an additional step to my testing of outlets!

Followed a discussion on the forum, M.H. does not moderate, and did not participate in the discussion.

Note, "Mike the Sound Guy" is not Mike Holt. :rolleyes:

We've discussed the limitations of 3-light "testers" and more expensive "circuit analyizers" dangers of use before, esp. pre 1984 work, use of same in 2-wire (no ground) and esp. in MWBCs or to test GFCIs installed in same.

[Aaron Miller]

Note, "Mike the Sound Guy" is not Mike Holt.

And JP is not HG. What's your point?

Mike Holt is responsible for what is on Mike Holt's website, no? Or will you and JP hold forth with more of your eisegesic piffle?

The only aspect of this sort of venue - the forum - that I dislike is that it has a tendency to promote sniping, when the purpose should be the dissemination of information. None of us will ever concoct a bullet-proof statement, so why pretend?:confused:

I apologize for the post, and in the future will only post "known facts" (whatever those may be):rolleyes: that have been agreed upon by both HG and JP. In other words, I will never post again.:eek:

Aaron,

There was no "venom" in my post. Maybe you thought so because your posts are on the edge of venom so often (much more subdued than previously), which is okay, but that does not mean that I, too, am full of venom.

To me, *you* "made a statement*, and *I* also *made a statement* - expanding on your statement and not wanting to prejudge Mike Holt based one your statement ... it was as simple as that.

I see.:D

Mike Holt didn't post on his "site", his forum participants did.

Mike Holt did post what I linked to on his site, and sent out same in a ("e")newsletter (which he often does when others have passed along safety information, etc. of interest).

Aaron, its akin to what me, you, and J.P. post on this (B.H.'s) site. Brian doesn't "vet" mine, J.P.'s, or your posts on his (this) forum either.

[Benjamin Thompson]

In other words, I will never post again.:eek:
Uhh Huhhh

OK. I understand your point.

HG:

Let us suppose, just for the moment, that there is someone who holds himself out to the rest of the world to be an expert on all things fromáge. Our turophile dubs himself the Big Cheese and authors a website with the same moniker at www.bigcheese.wiz . It is his aim to inform about the love of his life - curdled and molded milk - and to keep others' thoughts about cheese on the right track. On his site he allows for a forum to which he invites commentary on the subject. Some well-meaning, but sadly misguided soul posts a recipe for a feta cheese that may result in poisoning the digester. Does the Big Cheese have an obligation to make a careful and critical examination of (vet) the recipe and pronounce his blessing or curse upon it, or should he simply allow nature to take its course, resulting in the poisoning of others?:confused:

:confused: It looks like your new leaf to be kind and considerate of fellow posters, observed in another thread, has withered and turned brown on the tree.

In a word: No.

In a word: No.

No problem. We will simply have to agree to disagree.:)

That vid is wrong. You can not bootleg a ground and he should never of made the statement that alludes to it being electrically safe at 1.27. The ground is there to provide another ground path of low impedance (safety).

Also as for receptacles being upside down. Perfectly fine and done that way in hospitals and such.

The thinking is that if something metal drops and hits a plug the ground pin will prevent the metal object from short circuiting the hot and neutral together.

When all covers were metal, I think the original thought was a cover becoming loose and falling would not short the circuit. Now you see a lot of plastic and it doesn't really apply. Did see it commercially for a while though.

The thinking is that if something metal drops and hits a plug the ground pin will prevent the metal object from short circuiting the hot and neutral together.

The problem with that thinking, which was good thinking, is that the ground prong is made longer so that it will make first and break last, and putting the ground prong 'up' instead of 'down' defeats that entire purpose as the ground will 'break' first and 'make' last.

Again, though, there is no specified 'up' or 'down' for receptacle outlets.
