with this tweak, you not only save a lot of money in quality AC plug & socket; also, you get wire to wire contact, direct from the wall
i do this in every home i can; this one is in my new home; the 10 AWG power cord you see is feeding my PS Audio Dectet AC Power Conditioner, then all my system
WARNING! don't even try this unless you know very well what you're doing, since it may be VERY dangerous!

Would you feel comfortable showing your insurance agent this and asking if the company would pay out due a fire caused by any of this? Think you could get that answer in writing? Somehow, I'm doubting you could.

paco and ALL,
In one of your replies here, you said:
"if you read carefully my posts here you'll see where the disconnect is"
however, it is not at all clear from a casual perusal of this thread that the connection you picture is at the wall socket, and is meant to eliminate the Wall outlet and associated AC plug connection point with a "hardwire" attachment.
It is also not spelled out that the IEC portion of the cord is still in use, and provides the emergency disconnect if needed.
You also don't spell out the fact that the outlet box cover was replaced, thus preventing easy touching access of the wiring pictured, in was only mentioned in a passing manner in a reply to a question on the original post.
I think that before posting such a potentially dangerous mod, that it should be carefully thought out how and what you are going to present to the reader, and that there is no such thing as being too specific or careful or redundant with spelling out what is going on and why.
I personally can not recommend that any one individual attempt this kind of connection, because most folks would be in over their heads, and wouldn't necessarily be able to assure a safe and proper connection in the manner you propose.
I also feel that it would have behooved those who were hyper critical of the proposed mod to have looked carefully at the original post photo, which clearly shows a portion of drywall in the picture, thus establishing where this connection was occurring.
Nevertheless, it is not an easy or inherently safe type of mod, and should have been fully spelled out in every detail when it was proposed.
As always, with any AC power connection situations, following the electrical codes, and using best practice with any proposed cord mods, outlet changes, IEC connector upgrades, etc., is obviously a mandatory and necessary part of such activities.
If you don't know how to deal with AC power situations, then DON'T try to work on such mods or tweaks.

Sorry for being hyper-critical in this thread. I'll be careful to mind my P's & Q's, Jon.
Cheers, Duster
I don't think you need to apologize for pointing out something so damn dangerous (though the OP did offer his own warnings about it). There was a tweak/mod that someone posted many years ago that was deemed so potentially dangerous that the moderators deleted the post. AA moderators are pretty liberal, but they were not leaving it up for someone to say "I read about it on Audio Asylum!".

A moderator is the final arbitrator of any post in Audio Asylum. I can protest if I wish to, but as far as I'm concerned the point was made regardless of how much any criticism was deemed to be inappropriate to post in a public forum. The only thing missing in this thread is a calm and careful response from a professional electrician about the tenacity of the appropriately controversial notion in question.

Permanently connected equipment is required to have a means of breaking both sides of the supply in an emergency (your equipment is on fire for instance). In cord connected equipment the cord-set is the disconnect means.
Maybe a Frankenstein Switch might be fun.

if you read carefully my posts here you'll see where the disconnect is
yes! a GFI and switch! since that's the case why bother?
man, if anything goes wrong your insurance company is guaranteed to bail
if anyone gets hurt or killed you're guaranteed to lose in court
those with any conscious living with that knowledge would be tortured
further ... I'll bet it doesn't even sound better, maybe just different
the risk reward equation = don't do it
regards,
Wouldn't twist connectors, connecting the wires directly, achieve a better connection?
nope, these are the connectors professional electricians here use most; nude wires are in direct touch to each other all along the connector; screws are just to secure connections
I wouldn't want to have to explain that to the insurance inspector after a fire.
my tweak is just like a dedicated line, very well connected, so no danger of shorts at all, no heat, etc.; finally, the mess you see on the pic was like that already inside the box, before my connections; after the tweak, the cover of the box returned to place almost totally; i repeat: i'm doing this many many years, in different houses, but i do not recommend to anyone to do it, unless you can do it with total safeness and insight
Why not just hardwire the cable directly into the unit, without those crap connectors hanging out.
... not just saving money with endless experimentation with outrageously expensive connectors and wondering what this and that one may sound like because your method gives improved sound quality with less distortion in the power supply signalpath.. Not too practical for many. I for one, since I can read got your crystal clear warning loud and clear paco. Good post.

No AC plug, no socket, and no strain relief for the wiring. It's not a safe thing to post in a public forum. The message should be moved to Tweakers' Asylum where folks tend to have good sensibilities about the matter, and would be quick to point-out the lack of insight and carelessness.
"WARNING! don't even try this unless you know very well what you're doing, since it may be VERY dangerous!" Did you miss this in paco's post?

wrong! there is strain relief, but you don't see it on the pic; this is very close to the floor, where the big power cord is happily supported by several isolating beds
i'm doing this tweak for more than 25 years in many different homes; with care, never a problem! as i said, don't even try if you don't know very well what you're doing
As long as the cord conductors are sized for the branch circuit ampere rating I can't see why it would not meet code here in the US.
I do have a question. After you hard wire the power cord to the branch circuit wiring do you then check for the correct AC polarity orientation?

no legal problem here in Spain either...

well, it's not really hardwire, if by that we understand soldering; those screw connectors are really easy to use, and very common here among electricians
as for polarity, of course i checked it, but i did it before connecting, to determine live, neutral and earth

Here in the US it is considered hard wired if a plug and receptacle is not used to connect the power cord to the branch circuit wiring.

The correct AC polarity I am talking about is the AC Line hot and neutral polarity orientation connection to the IEC connector on the power cord.
You used the black and red conductors of the power cord for the current carrying Line conductors. Which one, color, did you use for the neutral? I assume the color you picked is connected to the neutral contact on the IEC connector.
FWIW, here is the US the white color conductor would be used for the neutral conductor. One of the other conductors would be used for the hot. More than likely the black conductor. The red would be used for the EGC, (Equipment Grounding Conductor), and marked continuously with green marking tape the entire length of exposed area beyond the jacket of the cord.
don't worry, i always use one of those test screw drivers to determine live on the AC line, then i proceeded accordingly for the IEC plug to receive the live in the right place; ground is obvious; many years doing that, OK?
