That blackening can be due to high current and lower (but excessive) resistance. Or low current through higher resistance. Or a third category - arcing. In all cases, energy (and burning) is a function of current.

Same current would also be in the other 'neutral' wire. But the neutral connection did not dissipate energy while conducting that same current. Same current says the hot prong had excessive resistance - the neutral did not. Why did the 'hot' have excessive resistance whereas the neutral did not?

One way blackening could occur is if the plug was not fully seated. But then blackening would not be at the base of that yellow plug. The plug apparently was fully seated. Resistance (or an arcing gap) was between that prong and the internal receptacle contact.

Properly noted is a problem common with 'back stab' connections. (An electrical connection that should never exist on circuits that power computers.) Again, not relevant here. Burning is in the wrong location.

Regardless of NEMA 15R, some receptacles (not just hospital type) have receptacle contacts that are superior. Exceed NEMA requirements - rated for more reconnects. And typically sold in the same Lowes or Home Depot for more money. This receptacle demonstrates what happens when a minimal contact is insufficient (ie contact pressure on the plug prong is weak).

His tirade implied a dedicated 20 amp circuit or line conditioner would avert or create this problem. He does not say with clarity. That blackening is consistent with excessive energy dissipated as defined by the famous "I squared R" relationship. A combination of higher current and higher resistance. Both must exist to create that damage. Same current also flowing through the neutral connection caused no damage. Only the hot wire contact was defective on that 15 amp receptacle.

So, how would a dedicated circuit or line conditioner changed that picture - as his outburst implied?

WOW!! all i asked was a simply question guys wasnt looking for a engineer answer or technical answer

this thread went way off and its being taken too far now. it was about power cords and some recommendations for them, not therories or mumbo jumbo talk. im allset if you want to end this pathetic discussion now. i ordered my cable and its on the way. didnt know it would turn into this

eveyone have a beer and relax and enjoy a nice blu ray movie, have some popcorn and thank goodness for good health. oh and awesome home theaters as well

I don't drink but I'm anticipating your write-up on the experience with your new cord.

Have a great weekend, Ryan!

, nope not here man. too many freaks talking about atoms and photons here


i will just get my cord and enjoy it for myself.

thanks, just was looking for some thoughts on power cords and wether they were worth it or not. doesnt matter now, got one coming and for those who care i will post my thoughts after it is hooked up and demo'd.

Good for you & I will be waiting to see what you think of them !
As John said before ~ solarrdadd is the one that will give you A straight answer when it comes to Electricity & things that involve it .

Good morning Ryan,

That's exactly what you should do.

However, I do hope that you read through some of the posts made by "freaks"! I certainly wouldn't categorize solarrdadd as one such person. In fact, I respect his opinions a great deal. Although the posts may have gone off-course from the original intent of your thread, I definitely learnt something and for that I'm grateful. I hope you did as well.

Just wanted to provide this as some food for thought.

John

nope, no ill will towards anyone. just didnt expect this as i have never discussed this before and was blown away by all the mumbo jumbo and how it went off coarse. i had some here that helped me and i guess that was good enough for me.

solarrdadd is great here and i respect him as well, infact he has helped me in other threads with his opinions and suggestions. no problem with him at all.

You asked a question that can only be answered in technical terms. Or did you want recommendations to be scammed? Even a simplistic answer is too complex?

Which is why everyone making recommendations provide no numbers. Too many posts are only wild speculation.

1) If a citation has validity, then it discusses connector and wire impedance, characteristic impedance, frequency response, and other parameters involving insulation. None are provided because the recommendations are based only in feelings. A classic example of junk science. Those wires are recommended only on myth – no numbers.
...
Monster Cable was founded on the same myths that now promote those 'miracle' power cords. That same objective is also why Monster Cable sells plug-in protectors. So many 'know' rather than learn. Which means massive profits by promoting a scam. Monster’s [earliest] scams were ‘miracle’ wires. Promoted by citations (similar to those here) that had no tech numbers.

If you smell something burning, is it popcorn ... or those wires?

But some people are just looking for opinions, or names of companies who provide a certain product. They don't want or need a thesis on the background and theories as to why it will or will not work.

Are LCD's or plasmas better? Do I care how the phosphors are energized in my plasma TV in order to give me a picture? Will I ever know who shot JFK with the "magic bullet?" Is God and Satan real or just made up by man many years ago as a bed-time story?

BTW, I am at 6.66 posts per day. Pretty freaking considering I just mentioned God and Satan in my last post.

The first paragraph said everything to those who only know what they are told to believe. Those other paragraphs were for the others who know only the most partriotic Americans only know something when they also know why.

Major difference between those who wait to be told and those who actually know. The beauty of that earliest post. Both types got the complete answer. One soundbyte paragraph (also called the executive summary) for those who must be told how to think. And reality - reasons why in following paragraphs - for those who only know something when they also know why.


For those who only need opinions. Power cords that cost less than $100 provide the wrong type of electricity. It is an opinion - the perfect answer. It tells us exactly how to think. Numbers? I don't need no stick'n numbers.

See... Humor... Brought a smile to my face.

BTW, I think they would be called Lemmings.


Thanks and have a good night.

I'm too tired for this... maybe tomorrow.

exactly!!!! i mean come on here, its a power cord for a home theater man. wasnt asking for a logical or illogical reason behind power cords.

lou hit the nail on the head with this statement, thanks lou

Regardless of NEMA 15R, some receptacles (not just hospital type) have receptacle contacts that are superior. Exceed NEMA requirements - rated for more reconnects. And typically sold in the same Lowes or Home Depot for more money. This receptacle demonstrates what happens when a minimal contact is insufficient (ie contact pressure on the plug prong is weak).

I never said there weren't, I stated that i stated the nomenclature NEMA would use to the device rated for said purposes by NEMA. yes, there are other receptacles that exceed said pressure but there is no NEMA designation for them. NEMA much like the NEC gives the minimum requirements. could you use #10awg for a 20a circuit yes you can and at times you must but you may also use the smaller #12awg for that same 20a circuit unless those "times" i mentioned exist then you may not.

His tirade implied a dedicated 20 amp circuit or line conditioner would avert or create this problem. He does not say with clarity. That blackening is consistent with excessive energy dissipated as defined by the famous "I squared R" relationship. A combination of higher current and higher resistance. Both must exist to create that damage. Same current also flowing through the neutral connection caused no damage. Only the hot wire contact was defective on that 15 amp receptacle.

I implied nothing, i simply stated what I used to get power up to my HT setup read it again.

So, howwould a dedicated circuit or line conditioner changed that picture - as his outburst implied?

first, what outburst, please curb or govern your passions or they will be your undoing. Nothing will prevent that damage if enough resistance or impedance exist on a circuit when energy is being consumed or "called for" and I never said either would prevent such damage, again, I simply stated what I use to get power up to my HT setup.

In your haste to try to make yourself look good and others look bad you are making yourself look bad while trying to do good. stop trying to talk over or down to folks your doing it intentionally or unintentionally. if this is how all your other post have gone on this forum, i can see why you haven't made any "friends" on your profile page. we come together as friends and kindred spirits to share our common passion for HT & blu-ray, not to weild a so called stick stick over others. it takes a big person to let something go as well you should. this post has really been brought down with your inputs and stabs at everyone.

everyone, please let's try to move forward, this will get us nowhere. let's put this one to rest so we can move on.

everyone else, lets either answer the OP question or do nothing or this particular tangent will go on forever! Oh to ensure we can make that happen, "Wescom, you are right and we are all wrong", better? now let's get back to being a happy loving community!

Please & Thank You!
