What is the technical term for the putty that electricians use to seal
around service cables where they enter meter boxes, or pass through
walls?

I've not seen putty used in that situation.

For service cables, I use a weather head, bend the wires down prior to
entering the weather head (drip line), and don't use anything to seal
the holes.

For wires entering through the wall of a building, I route the wire
down, then back up (drip line), then use regular caulk.

Dust Seal or Duct Seal Compound is the trade designation of the
material.

I've seen "Diversigum" used. At least, when I did HVAC
installs, that's what we used. The boss used to call it
"thumb gum".

Sunlight UV makes it brittle after a few years. But, it does
provide some sealing.

Now, for the OP question. What is that putty?

*Duct Seal

It's Duct Seal, or as manufacturers call it, thumbgrade.

We use it only to seal conduits going into hazardous areas. It will
prevent a dust explosion from propagating through conduit, at least in
theory.

They sell it in all the big box home improvement stores, BUT the
actual purchasers are a very specialized group.

The only people who buy much duct seal are airgun shooters. Duct Seal
makes an ideal pellet trap, just fill a flat box with it. It absorbs
a pellet silently and traps all lead dust. Every once in a while (few
thousand rounds) you dig out the pellets and smooth out the duct seal
again.

Long ago I talked with an old timer at Johns-Mansville or whatever
they were at the time who used to make the stuff. It's basically
calcium oxide and grease, made in a big pug mixer in batches of about
1000 pounds at a time. Of course he wouldn't tell me the real
recipe.

And who said you never give helpful answers?

Likely you have never even tried it because great stuff isn't UV
resistant so it quickly turns yellow and gets brittle. Other than that
it looks great on those infomercials.

On the other hand the stuff (duct seal) electricians use is easily
applied with your fingers without any mess and stays pliable for a long
time.

When I used to work in my fathers auto-body repair shop in the 1950s, a
lifetime ago, we used a similar sealant to plug holes where wires and pipes
went through the body. In those days it was called "dum-dum", it sounds
similar.

I have tried it. Six years ago to fill the voids around a new circuit
breaker box. It's still there.

In the event it does turn brittle decades from now, who cares? Bricks are
brittle. As long as bricks, or Great Stuff, are not under shear stress,
brittleness is irrelevant.

At work, the red stuff they use going through walls is described as fire
stop. Never stuck my fingers in it, since it is up so high, but I always
assumed it dried hard, like drywall mud.

Or am I talking about something different?

Ducseal is one brand - often called DUMDUM. It if fireproof. I think
the original stuff had asbestos in it - not sur what is in it now.

Very fireproof. We used it around cadweld mold holes to contain the
liquid copper when connecting copper cables to ground rods.

Absolutely relevant for the application. There is a really valid reason
why certain methods become standard methods.

Oh, I mostly agree with conventional wisdom. So what is the "standard"
method in the instant case?

There is also some stuff called "Coax Seal," available as strips in
small quantities used by ham radio operators to seal coaxial fittings
out-of-doors. It is really sticky and never seems to harden. You need
something like lacquer thinner to get it off! Any good ham radio
supply house, or by mail order. Good for small jobs.

You mean you don't bother reading replies to questions that have useful
answers? I believe there are at least three posts in this thread that
list the time tested and proven product that is ubiquitously used by
electricians.

Just wanted to follow up on one of your other great suggestions. We are
having a blast using that idea of yours to build shelf hangers out of
light gauge wire. Unsuspecting people set a heavy object on the shelf
and next thing they are on the floor under a pile of stuff. It is
hilarious...

I have never heard it called anything but "duct seal", but lots of
products have different names in different areas. The last box I bought
was labeled "Duct Seal" (Panduit).

Where a conduit or sleeve goes between areas of different temperature
where "condensation is known to be a problem" an _"approved material"_
is required to seal around the wires or cables (300.7-A). The seal
prevents warm moist air from circulating to the cold area. Around here,
inside the service conduit into a building is always sealed. There are
other places where it is appropriate.

"Fire stop" is to maintain the fire rating of a wall or floor, but
should work.

Can't imagine protection to a hazardous area wouldn't require a seal-off
fitting with appropriate seal material. Can't imagine duct seal being
used as a hazardous seal.

Oh I read the replies. It's just that I figured they were, to you, as
cockamamie as mine. That's why I asked for your recommendation. I take it
from your lack of reply that you don't actually have an idea other than
disparaging those of others.

Only if you take pleasure in the misfortunes of others, which, when I think
on it...

You mean this reply I made in this thread:

"On the other hand the stuff (duct seal) electricians use is easily
applied with your fingers without any mess and stays pliable for a long
time."

Or where I noted in my reply to you that at least 3 others noted the
same product:

"I believe there are at least three posts in this
thread that list the time tested and proven product that is
ubiquitously used by electricians."

Around here there's a lot of "Jerry built" stuff - half the
population is German ancestry.

"Jerry rigged" is used for poorly done - also referred to, for some
reason, as "jury rigged"

A lot of people call it elephant dung. I just call it by the name on the wrapper,"Duct Seal". Wouldn't it be fun to buy a lot of it, put a new wrapper on it that actually read,"Monkey Shit"? I could be a popular gag gift for contractors and mechanics. \(◦'⌣'◦)/
