I am going to be splicing a copper conductor to an aluminum conductor. Is there a split bolt made of a specific material that I need to use?

Yes. It will say Al and Cu on it and will have a divider to keep the copper and aluminium apart.

If your connection will be outside, orient the connection so that the copper conductor is below the aluminum.
In time rain water can infiltrate your connection and with it carry copper element with it which will cause aluminum conductor to deteriorate. So by placing the aluminum above copper it greatly reduces the effect of corrosion.

What size conductors? There are some set screw barrel splices that I like better than split bolts.

These are good if you have the tool.View attachment 13544
but if you had the tool, you would know that already.

just a simple hypress butt splice that is AL9CU rated works well,
but then there is that tool thing....

Better yet, these:
Made by Ilsco.
or polaris.... these get my vote over a straight split bolt.

Especially when the proper split bolt costs 7-8 dollars and still has to be gobbed up with tape.

While the compression tools are a bit expensive, the connectors/splicers/adaptors are less than the screw type mechanical ones. I think the long term investment of compression tools is worth it.

it is a convenience, as it will make an irreversible connection without heat.
all my cadweld stuff is in a box on the shelf now.
not cheap to get barbie and all the accessories, however. didn't go with the
universal die head, went with a 12 ton and C dies... bought three different
sets off ebay..... one for CU to 750 mcm, one for AL to 750 mcm, and one
with all the dies for grounding, etc. couple of duplicate dies, but the sets
were still the way to go. i've seen three jobs now that specify hypress fittings,
with dies specific to the fitting, leaving witness marks. no universal stuff.
doesn't make a lot of sense unless it's to filter out the harbor freight "universal"
hypress kits that are $39. the universal crimpers from burndy are listed and
approved.

Now that POCO's have battery and hydraulic tools, there are probably a lot of the old style with long wooden handles for sale cheap. I found one in a pawn shop, talked it down from $12 to $6. I would not want to use it all day, but it's great to have for occassional use.

So does our POCO. That's what they are using, installing them with cordless impact guns.
They are pretty slick. My house is hooked up with them.

On new or upgraded or repaired residential single families, we make our own connections to live POCO conductors and these are what we use. We put the covers on the 2 hot conductor connections and leave the neutral "bare".
