Inexpensive 200 Amp 3-Pole Distribution Block for 4/0 Cable

[Ryushin]

I've read no so great stories about using Polaris connectors about how they loosen up over time. I have a manual transfer switch and I need a 3 pole tap.

Watching Engineer775 Youtube videos, he has been using some nice distribution blocks. I believe they are Mersen:

I've seen distribution blocks price to over $600. The Mersen is close to $300. Any affordable options available?

Perhaps I should just use a drop of blue locktite for the Polaris connectors?

Here is a link to a Marathon distribution block from Galco.com. This is one example they have a fairly good selection.

I did look at Galco. I may have missed it, but I could not find anything that could do 4/0 with a 1 into 2 3-Pole. I need to create a tap for L1, L2, and Neutral.

I guess I missed it, Galco does have one for $375.00:

Too rich for my blood. Looking to stay under $150. Three Polaris connectors I think will be under a $100.

That link shows 2 AWG into two 6 AWG.

I'll go through that PDF link and see if I can find something along that same price range.

That link shows 2 AWG into two 6 AWG.

Input Wire Range	600 kcmil-2 AWG
Output Wire Range	250 kcmil-6 AWG

Input is 600kcmil at the largest to 2awg at the smallest, 4/0 is in that range. Output is 250 kcmil at the largest to 6 awg at the smallest, 4/0 is in that range as well.

Wire sizes above 4/0 specified in kcmil or mcm (same thing) that start at 250 and go up from there.

These are not as cheap as a the Polaris option, but Home Depot has NSi blocks for under $100. You'll have some unused holes.

OP has already stated he prefers not to use Polaris Lugs

 

[Ryushin]

Well, I been reading about the Polaris plugs become loose over time, which could cause a fire. I supposed some blue locktite could be used on them.
