In the owner's manual for my (new to me) Delta TS (36-841), it says:
"This circuit should not be less than #12 wire and should be protected
with a 20 Amp time lag fuse."
Not being aware of this detail until now, I was just going to use a
regular 20-Amp circuit-breaker (I ran #12 wire). Please advise. Thank you!

Congratulations, Bill! I've had my Unisaw (Delta 36-844) for 6 years
and have had no problems with #12 Romex (about 15ft from sub-panel)
and this (standard?) Siemens breaker:

Yes, in the circuit external to the motor but not if the motor itself
is considered. The voltage across each winding is 120V and the
current in each is 10A, whether it's wired as 120V (parallel windings)
or 240V (series).

Even though this is not DC...Ohm's Law says your theory is wrong. I=3DE/R, =
if you double the voltage you halve the current. Also, wattage would prove =
that out. The same motor wired 240, would draw half what it did on 120. On =
single phase, the neutral (white or ground) is the center-tap of the power =
transformer. That's why it's half the voltage.

Looks like you're on to something.
- Sparks flying is a bad thing.
- You can glue/solder pieces together, but it's not always a good idea.
- You can never have too many clamps/outlets.
- Measure twice, cut once applies to electricity too. (Measure, power good,
cut off at breaker, measure again, no power, probably safe to work.)
- You don't have to match colors to make things work, but not doing so is
the sure sign of a clueless hack. (Intentional mismatching is ok.)
- Hand planes and wire strippers remove the outer surface of the workpiece.
- Copper turns green with age, so do trees.
- Running the wood backwards through the saw won't reattach it... Not even
if you swap the motor leads.
- The sun can be used to generate wood or electricity.

You may want to put a 30A breaker on it. In any case, be sure the
breaker you use is "listed" for the wire you're using.

Current (when there is a load) is the same at any place in the circuit, regardless of being 120 or 240.

However a more that needs 20 amps at 110 volts only needs 10 at 220.

The breaker equivalent of a "slow-blow" fuse is called a "high
magnetic" breaker. If your regular breaker is tripping on startup you
might want to consider going that route. Personally when I run into tht
though I generally just rewire the tool for 220 (if that's an option)
and run a dedicated circuit. Most tools seem happier with 220 anyway.

But you do realize that the 240 in your home is made up of 2 out of
phase 120 circuits...

It is, really, except that the two circuits are out of phase, so they
add (if they were in-phase, they'd subtract).

Yes, on the pole, and the neutral is brought into the panel. However,
there is no neutral in this (240V) circuit. It's not needed because
the saw doesn't use 120V (if wired for 240V).

Yes but a 240 V circuit has two 20 amp leads, a motor drawing 20 amps,
10 per leg.

Nonsense. My 3HP Unisaur has been on a 20A (240V) circuit, with
20-30' of 12-2 W/G between it and the panel for years, with zero
trips. Come to think of it, it was ~50' in my last house.

There are a bunch of woodworking EEs. ;-) It seems the two
disciplines use some of the same mental skills.

However, there are differences. Wood can be used to make electricity
but the other way around takes a *long* time.

No, in addition to the thermal detector, circuit breakers have a
magnetic trip. A high enough current will trip the circuit before the
thermal detector can trip.

In trying to answer my question, I learned that
"all circuit breakers are "time delay" by nature of their design."
So, I guess we'll see what happens...
Progress in the shop is continuing after a delay or two in recent years
caused by major events.

Nope, he'll be fine (as he discovered in further research and posted) as
circuit breaker as opposed to fast-acting fuse has enough inherent lag
time for the motor...

As others are pointing out, you'll be fine.
Old fuses would blow with the initial spike of current when saw motor
kicked on.
A modern circuit breaker needs to heat up to trip (except in the case of
a short) so it can't get hot enough to trip from the very short current
spike of the motor's start-up.
At least that's my layman's explanation of it. :-)

"Fast-acting" ones, yes, "slo-blo" (specifically designed for motor

wouldn't.

...
The fuse had to heat up, too (in fact, it had to actually melt) but the
idea is correct; they are designed to handle motor loads inherently to
be general-purpose; it would be a real pain to have to have separate
breakers for the application.
The time for a dead short to heat up and trip will be quite a lot
shorter than that for the motor start; while a motor start is a
(relatively) high current (say 3X or so of full load), that of a dead
short is I=V/(R-->zero) --> Infinite.

Don't know why you'd say that. He's well within the current loads with
#12 wire and an 20A breaker.

Well, yes, I said that in the very beginning that his general ideas
were/are correct but added some amplification as to "why" and "what"
actually is going on.
Was that needing comment for some reason?

The "potential" is a voltage term. The 2 "hot" wires are in phase for 240 s=
ingle phase. If you took 2 120 Volt circuits from the same side of the pane=
l (in phase) black to black, white to white...you would have effectively, t=
he same circuit at 120 V. 240 out of phase? Not sure of the consequences of=
that!

First off there is a single phase, a 240v circuit needs no neutral.
The potential of the two legs is 180 degrees different to cause that
potential.
A 120v circuit require a neutral return path.
If you have two signals that are 180 degrees out of phase they cancel
each other. That would be a two phase system and you only have one.

That's because it gets 10 amps on Each of Two legs at the same time (I
think "legs" is the right word, I could be wrong).

I get it. I'm also gently reminded/informed that a 240V circuit is Not
the equivalent of two 120v circuits.

Yes, that's most-surely what led to my confusion about the way a 240v
circuit works...
So, a 240v circuit apparently doesn't have a direction....or rather, it
has 2 directions at the same time, from one leg to another, and vice-versa.

I get it! Thanks! Am I the only one here who didn't know that? :)

That comment makes me wonder whether you really understand--as well as
Bob Villa has explained it.

Not true. The motor will draw half the current at 240V, as it would
wired for 120V.

Running large stationary tools at 240V is certainly recommended (I
think the OP has already gone that way) but there isn't a lot of
reason to run dedicated circuits in a home shop. Several tools can
share the circuit, since you aren't likely to use them simultaneously.
The exception, of course, is a DC.

You're good to go. Household circuit breakers are pretty much
equivalent to "slow blow" fuses.

Does the Australian electricity turn the other way?
