For me in no particular order. :smile:
- Don't have any green at all.
- I have green but it's out in the truck.
- I don't feel like it.
- There is no room in the conduit.
- It was not in the specifications and I don't give much away.

What exactly is '3 times the heat'?
2 years ago?? The problem with tinkering and too much crammed in the head:wink:
both at ~67 F start (appx)
After coffee break 20- 25 min ~
Screw to 69 or 70 F
Compression to 73 or 74
Fluke IR Camera from PM Tools.
amps ??? I forget
We had left it with Pop off jammed open.
More detailed and i would have to get paid to do it again
And I would have to find that darn compressor too:smile:

I guess I wouldn't call a 4?F difference '3 times the heat'.
I'm not particularly well-educated on the laws of thermodynamics, but even if one fitting measured 70?F and the other 210?F, I doubt the comparison '3 times' would be appropriate.
Not busting your chops here, but I'm just trying to come up with a better phrase to quantify the difference. Perhaps "indicated a slightly higher temperature"?
No Chops Busted..

Me either, And I don't do reports often.
We did this just for fun...
Never settled for them the question of Scotch Locks verses Crimp lug/bolt for motor terminations. small motors.

Actually, the most widely accepted spelling is "smuts", as in the plural of smut.That's "schmutz." L'chaim!
you failed to indicate the ambient, the heat source, and the pipe temperature on or near the connector. these factors would have probably been significant. for example, all I can determine from the information provided is that the compression connectors conducted heat better, which is possibly because they had better contact with the pipe ?2 years ago??

Maybe less area, but definitely greater pressure. I try to drive the screws all the way. The deeper the dimple, the better the pull-out resistance and better conductivity. It's certainly not going to impinge on a properly-filled conduit's area.

Smut was derived from shmutz (Yiddish) and/or schmutz (German). Means the same thing.

Compare each rise from the original of 67 deg. SS: + 2-3; comp: + 6-7. That about 3x.
Yes, that's what I'm trying to state. The temp. rise was a factor of three, not three times the heat.
If it's '3 times the heat', then would you not multiply 69?F by three, which means the comp. fitting is 207?F?

Yea, when I read the first critique I saw my error. I just let it be. I say the word sCHmutz, and am of (some) German descent so out of respect of my fore-fathers and mudders I'll schtick wid da schmutz...That's "schmutz." L'chaim!
I have no definite exceptions here, but one would be no room, and a new conduit is a major undertaking. I am more easily encouraged to omit "green" when running in RMC.
Has any one found a particular set screw connector and or coupling with a snugger fit on the EMT? Off the top of my head I prefer OZG steel connectors, and detest most any cast ones.
I don't recall which of the compression conn. I detest, but I have had experience with some that compression ring liked to get fowled up in the threads... It was frustrating. Maybe they were used?
Regards,
Doug S(ch).

Snugger than what?
I like the steel fittings much more than the cast ones. I think the ones I've been getting lately are Bridgeport, but I think they're all more alike than different.

Of course the main issue is installation. Appropriately installed the compression connector provides a larger contact area, therefore less susceptible to oxidation and corrosion on the long run.

Oy, don't be a kvetch boychik.:grin:That's "schmutz." L'chaim!

It also helps to know that Yiddish is a conglomerate language, derived from Polish, German, etc., as well as Hebrew.Perhaps its origin depends on the reference...

I just don't see the relevance. There must be an implied reference that you're just not letting on about.... :-?
