Cable stripping

[The electron man]

Here are some pics of connections i made in a switch gear/copper detail was wondering if i stripped the cables too much?

They are stripped long enough but they were stripped incorrectly, you nicked them.

nicked them ? Please explain thanks again

 

[rambojoe]

You cut through the insulation and cut the cable on a few of them. Cutting along the length of the cable helps a bit, it just takes practice...

Is there any chance of a line to line arc in a 480v with some exposed wire as shown ?

 

[rambojoe]

The lugs also seem to be just big enough, but itll work.

No. Personally I like the insulation to be right up against the terminal but that is not a code requirement. We use a sharpie to mark the exact length and after a dry fit if it's too long we trim the bare conductor to the proper length.

I don't see it as being any worse than the bare lugs.

Assuming you remembered to remove the allen wrench??

Once you get the length good i just use the stripped insl. as a gauge. Helps when you have to haul butt...

I do intentionally leave a bit sticking out so that the DE-OX is visible. Not that much but 1/8 inch is good.

It also helps to make a nice pretty seal around the port w/the antiox- if its small enough...
Its the small details...

My journeyman likes it done this way , he claims it allows the strands to spread and make a better connection

No offense to your J-man but that sounds like a bit of nonsense. I've never heard that one in nearly 40 years in this business and to me it's far from aesthetically pleasing which is part of the installation.

I've never seen overheated conductors because of this either

As long as the bare part of the conductor goes all of the way into the terminal the most important thing is proper tightening torque.

 

[Tulsa Electrician]

Most gear,breakers etc come with instructions coving recommend stip lenght.

Not sure how many people read them. Ask you j man for the installation instructions take them home and read.

Here is a pic from ilsco

Nothing like learning something new. I learn something almost every day.

No. The lugs are closer together than the stripped wires. But yes as bit shorter on insulation. You would find it’s faster to tighten lugs with Allen socket on ratchet wrench, or likely you have a torque ratchet wrench

 

[electrofelon]

I find it sloppy, but not a code violation. Also the deox looks sloppy and inconsistently applied.

Our working standards allows an 1/8.
