I have roughly 120 connections to make involving 4 #8's a piece. What's the best way to connect these. Only thing I can come up with is a insulated lug. Suggestions.

I guess to be clear I have 4 11/16 boxes with 3 flex whips and a 1" EMT entering it. TH e flex whips are comprised of 1 #8 black, whit, and green. From the 1" I have a mwbc with black red blue, white and green. The joints for the green will have 3# 8's and a #10. The neutral will have 4 #8's. Are insulated lugs or split bolts the only option to make these connections?

Polaris taps. I don't think a blue is gonna hold 4 #8's

I'll second the polaris taps too...I am not a huge fan of blues...or try ilsco or burndy they all have something that will work.

Split bolts are a pita, by the time you finish taping everything up properly, you could be onto the next box.

Isn't that 4116 box a bit small? A 6x6 would probably be a lot easier to work with just my opinion though...

I second 4-11/16 too small.

I highly doubt a 4 11/16 box is rated for 11 #8s, but I could be wrong. Might want to check your box fill on that one.

Already ordered extension rings.

Why not let the unused conductors of MWBC in each box pass through? Just drop off and tap to whip whichever conductor is feeding that particular whip. That cuts you down to 3 #8's in each tap. Feed in/out plus whip. 3-8's might go in a blue?

 

[Legacyelectric]

Never mind. 3whips in each box. Thought I was smart for a second.

The 2-1/8 deep ones are.

Did the calcs on bbox fill the other day and I think I was short by the ground alone.

Do a google search for "Pan Lug" copper compression parallel splice by panduit

They have a wide range of conductors they are listed for.

They also offer heat shrinks for corresponding crimps.

The investment may be more of you dont have a tool but with all those splices it might be worth it

You only count one ground.

i just completed a job with 200 terminations just like that. one word: Blue Wirenuts

 

[Southeast Power]

sorry to say that who ever laid it out kinda screwed ya. you will either have to find a way to split it up it, exring it or buy polaris taps.

That's not one word

Blackburn makes wr-9 crimp that will take three 8,s easy.
Alittle splice tape and your done

Blue wirenuts are only good for (3) #8's.

I know. I did the calc in my head the other and I think the box will hold all of the wires but when you insert the ground into the calc it is overfilled.
