Let's see, power goes out, lights go out, hand reduces down/forward
pressure, wood kicks, fingers hit hot dog blade that's spinnning full

if hot dog man has that one covered?


If the saw was running, it will stop if there is a loss of power. Yes
the stop will work if the saw is turned off.

Capacitor


Do you know that for a fact, Leon or is that speculation? Yes, a
capacitor could be used to discharge the SawStop mechanism but I'm
wondering if it's also set up (assuming that this is NOT a speculative
solution) to power the sensing circuitry.

Yes I know this for a fact, I did the research. Power goes off what
powers the motor? According to Sawstop the protection will probably be
available for a second or two. Past that you are on your own. If you
are cutting wood when power is lost any saw will stop faster.
If there is no power loss but the saw motor is turned off the protection
continues through coast down.


In any event, strike your phrase "if the saw is turned off" as erroneous
and/or misleading. If the saw is turned off, how would you ever change
the blade without the device triggering. Better to say "even with a
loss of power" (if such is truly the case).

NO do not strike the phrase if the saw is turned off. Just because the
saw is turned off does not mean that the blade is not spinning... I cut
half my thumb off after turning my saw off and reaching to remove the
rip fence after performing a dado cut.20 years ago.
