It is none of the above .
To me it would indicate a 3 phase system used in Industry and Commercial systems.

I agree as it is worded. If you think of it as three fuses, there’s an answer that would work. . .

They Used to do that when I was a baby only it was single phase and only one hot wire.

A Sub Panel is present is the correct answer, so is there sufficient evidence to change the question?
If so please provide references,

the word “might” in the question allows for more than one correct answer
The missing info that we always have on an inspection is the type of wire, direction of it etc. This info is what determines the arrangement of the installation.

A three pole main disconnect might indicate:
Single phase power.
A “fused” neutral conductor.
A sub-panel is present.
Allowance for future upgrades.
A 3 pole disconnect is not to be used in a normal Home .
These are for industryand Comerical .

True Roy but the question pertains to " when you do see one in residential" It may happen and HI’s need to know the possibilities.

I agree they need to know the possibilities.
There is only one! it is wrong and must be repaired .

The question never stated that all three poles had wires present. Nothing wrong with using 2 poles of the 3 as long as the rating was correct etc.

How on earth is a three pole breaker indicative of a “sub” panel? Picture please.

Wrong it was designed for industry 3 phase system .
I did a home that had a 3 phase 120/208 volt panel in it.
It had 120/240 volts single phase coming into the home .
The panel had only 2/3 of the breakers in it as the other 1/3 was not able to be used.
Again wrong requires immediate upgrade to proper panel.
Years ago they used to fuse the neutral but not any longer.

Mine too. I am still waiting for someone to explain why a 3-pole breaker is indicative of a subpanel.
Roy, I don't understand why a 3P panel installed as you described is cause for immediate replacement. Sure it hokey, but is there any code violation? Is it dangerous?

CODE I do not have a code book .
I do not do code inspections.
Wrong yes defantly.
Dangerious yes you can be sure some ( Not a sparky) who knows all about every thing is going to put in a jumper to feed the unfed 1/3 of the panel. You now have 1/3 on leg one and 2/3 on leg two .

I wonder...The question says "disconnect" not breaker. If we're talking just an old-style 3 pole pull handle disconnect, it would have to have a "sub" panel with fuses or breakers. Sometimes you'll find them lingering around ahead of an upgraded breaker box, because it allowed John Q Fixerupper to install his own breaker panel without having to pull the meter, which would then require the Utility Co, and they in turn would require a licensed sparky, in most municipalities I know of, to install the box and main breaker.

So it does.

Again, how is the "three pole pull handle" indicative of a "sub?"
Three poles indicates nothing more than three conductors. In most cases, this is seen when older systems had a fused neutral (fuse at two ungrounded conductors and the grounded conductor). Otherwise, logic would have it that there would be a three phase system (fuse at each ungrounded conductor).
Most load side panels ("subs") have their own - two pole - disconnect at the service panel.

Sorry I am wrong.
The inspection Dept does not like to see three phase disconnects on a single phase system and they are not happy with them but in Ontario they can be used .
Three phase Panels can not be used in a 120/240 single phase home system.
