Load panel terminology: stab?

[Moi]

It's used in a load panel sticker that says something like "do not put more
than 150 amps on one stab".

What's a "stab"?

The individual 'slot'.

The individual 'slot'.

Is it one slot, or a pair of slots sharing the metal tab?

The fork finger that grabs the bus bare..

Yes.

 

[krw]

Its a BUS BAR or a BUSS BAR, dumbass.

The correct spelling is "bus". "Buss" is a proper noun and "buss" is
wrong unless you're in love.

....and if it doesn't grab the bus bare it won't work. ;-)

OHHHHH< I forgot 1 "S"

I must of been thinking of using it for the word
"SHIT" head, I knew you would be drooling all over my post..

Why don't you go back to your closet and stay quiet.

Good for nothing puke.

Parasitic parasite. Malignant one at that.

Well it could be a bare assed bus bar...

 

[DJ Delorie]

Yes.

I should know better than to be vague.

Is it the space one circuit breaker takes up?

Is it the metal tab that two adjacent (end-to-end, not side-to-side)
breakers share?

Is it the space that those two breakers take up?

Please don't let "Michael A. Terrell" see that.


After reading his replies of an error he claimed, I made, I did think
It was an error until a rethought about it..

Normally I would use BUSS and not BUS how ever, BUS is correct.

And for you jerky "Michael A. Terrell"

Please tell the editor of this patent, they have miss spelt it

After all, M.A.T. you do know everything there is.

For any one that really wants to know.. Don't take it from me.
Even though I've been in the business for years.

Ok, that's clear. The metal tab is the stab, it connects to two
breakers.

Of course it depends on where you are, but two adjacent breakers are
usually on opposite sides of the line so the answer is the same either
way.

 

[krw]

Yet there are ads on Google for 'Buss Bar' suppliers.

"Buss" is short for "Bussman", which is a brand of such things, hence
a proper name. Yes, "Buss bar" is a proper name for one brand of bus
bars. "Buss" is kinda like "Xerox". With a lower case 'b', "buss" is
a kiss.

 

[krw]

Come on. You know it needs a coat of No-Ox.

Only if Mr. Bussman's first name is Al. ;-)

If they're adjacent on the long edges, yes. If they're adjacent on
the short edges, no. That's why I did NOT say "adjacent" in my text,
it would be ambiguous.

In my panel, breakers are numbered like this:

breaker1 breaker2
breaker3 breaker4
breaker5 breaker6
breaker7 breaker8

Breakers 1 and 2 are on the same stab.
Breakers 3 and 4 are on the same stab.
Breakers 5 and 6 are on the same stab.
Breakers 7 and 8 are on the same stab.

Breakers 1, 2, 5, and 6 are on the "A" 120v line.
Breakers 3, 4, 7, and 8 are on the "B" 120v line.

Ah, here's a good photo:

So any double-wide ganged breaker will always pick up both lines,
giving 240v, and two breakers across from each other always pick up
the same line as they share a stab.

Aren't most new breaker boxes?

No. At least all I've seen are copper. The one I bought recently was
nickel plated though.

I've had to replace several with both
aluminum bus bars, netral and ground bars after one or more failed. The
new breakers i see have a contact lube in them.

None on mine.

Yes, exactly.
