1" conduit connectors

[Frank S]

What do you do when it is Saturday afternoon the local hardware store closed at noon and you are right in the middle of wanting to run some 1" emt conduit when you run out of box connectors?
Well you can drop everything and drive 75 miles 1 way to the next open store then by the time you get back you are either out of time or out of the mood plus you spent $20.00 on diesel just for half a dozen connectors.
Or you do like I did you go to your pile of usable stock and someday materials dig out several cut off pieces of 1" pipe that already had threads on one end cut off what you need and bore them half way through to make your own box to EMT connectors
1" pipe is the same thing as what is called 1" ridged conduit. the threads are the same as well. you just need to bore it out large enough for the EMT to slip in this works for 1/2, 3/4, 1 1/4" 1 1/2" 2" and so on Only when getting above 1 1/2" the shell thickness may be thinner. I haven't ever had the occasion to try anything larger than 2"



My fit was almost a tap in fit and the conduit is going between 2 boxes so I really didn't need the locking screw but put in in anyway by making a weld glob then drilling and taping to 10-24

Herein marks only time Frank S will refer to his welding a 'glob', it being intentional. His projects often include welding; I'd have no apprehension standing under same, compared to the 'popcorn' variety common on youtube.

Yeah well it is a glop but probably with 70,000 PSi tensile LOL It is at least strong enough to hold the screw

That’s only if it’s a 7018 or some other 70** series glob.

Pretty much have that department covered I think

I’m having trouble with ksi? Is that 1000’s per square inch or kg per square inch. Or something totally different?

I just looked up your wire. Your using a wire feeder! I’m an old fashioned stick man myself. My dad was born in 28 and was a welder for 70yrs. He loved to torch weld. Even in a world of easier options he loved the feel of that torch in his hand. His welds would look like tig. He was a master at his trade. He taught me to stick weld first and the others came later. I always came back to the sticks. I loved what you could accomplish with them. You don’t have to worry about the air around you moving. Your base metal can be a little bit rusty or greasy. Not to mention super portable. No torch to over heat. I think it’s a lot easier to weld heavy trailer hitches and the like with stick. A mig machine big enough to weld 1in plate is not cheap. A used 300amp Lincoln Tombstone can be had for 200 bucks these days.

An a journeyman electrician, my first thought was "Where's the UL stamp?" Otherwise that's some nice problem solving.

Where I'm at most folks don't even run their wiring in conduit you should see some of the nightmare wiring in many of the barns and houses around here.
years ago I was wiring up one of my 25 or 30 hp power units this was overseas so I pulled 5 wires since I needed a common for the controlling aspect of it. one of the guys asked me why I pulled a green wire since my conduit was steel. Rather than go into a lengthy explanation about proper Earthing I just said because I have green wire then pointed to the non conductive PVC flex conduit inside of the power unit.

Such comments prove maybe electrical work, compared to other utilities [not gas] and general trades, has more unaware fiddling about that becomes hazardous. Old saying applies; a little knowledge is dangerous.
