ECN Forum Forums General Topics of the Trade General Discussion Area Trough sizing...

I was visualling (2) 150 amp breakers in the above panel, and main lugs on the bottom panel, you hack.

It's OK, I'm a hack too

It's a heck of a club.

At least your 'orientation' was not questioned.

LOL...Um...nevermind

If you guys are starting a club, how much are the dues? If its a hack club I think I should be a charter member!

Well...we're not quite sure who the voting comittee is yet.

Iwire-

I wish I could cut and paste a drawing here, but here goes...

If you had a box/raceway that is 7" tall x 24" wide x 6" deepand it has one 3" EMT coming in the left and one 3" EMT going out the right of the box, the top of each EMT being 1" from the top of the box, you would consider that a "Straght" pull.

Now, using the same box but having one EMT being 1' from the top of the box and the other EMT being 1' from the bottom of the box, would you consider that an "Angle" pull?

Hope this made sense.

... I'm sorry gentlemen,..I just got in,and checked this thread since the last time I posted this morning..

... Yes,Bob, you got it,..I intend to splice in the trough,250kcmil(300a.) to(2)-1/ "ought"(150a.) How do I make the symbol for "ought"??

If a hack like me was to use wireway Tee and Elbow fittings, then what would the result be?
Most wireway sections are marked with a maximum conductor size for conductors coming in the sides. This doesn't correspond at all with 314.28, but addresses wire bending space.

Steve I understand your description.

I am not sure of the answer, I think that was what Ryan is getting at.

Is a straight pull literally straight or just on opposite sides?

For what it is worth in my opinion a straight pull means that the raceways line up directly across from each other with no deflection of the conductors.

Any splice, deflection, change of direction etc. is an angle pull.

Scott I am not sure, I certainly have seen sets of 600 Kcmill enter the top of a 12" x 12" trough but I doubt it meets code.

The company I work for is more concerned with progress and passing inspection than worrying about the cost difference between an 18" x 18" can or a 24" x 24" can so I tend to figure big most times.

I also try to plan my pipe runs in a way that I can use trough the long direction as a required pull point. I typically will use a 6" x 6" x 48" trough with 4" raceways.

How about you place a 12" x 12" x 18" trough vertically between the panels. Enter the 3" in the top and come out each side with your 2" into the side of each panel?

3" x 6 = 18"

2" x 6 = 12"

Hey, I think I might be a member of that club too.
