See the poweroff section of the script. My question is:
"Since I do not have much knowledge on how the Linux system boots and
shutdown I have spent the last several days searching for how the scrips
/etc/init.d are supposed to work but every thing I have found is a
little different than what I find on my Ubuntu system. Does this script
ever get called with poweroff?"

For NUT to switch off your UPS at the end of the shutdown sequence,
you have to edit your shutdown scripts.
See INSTALL, "Configuring shutdowns for low battery events", item 11
"Edit your shutdown scripts: add upsdrvctl shutdown".

Nut will monitor the ups and shutdown Linux when the ups goes to low
battery as it should. But the UPS is not shut down so the system will
restart when the power is restored. If I switch the UPS off , restore
power and switch the UPS on the system will restart. I have not been
able to get nut to switch the UPS off after it brings the system down. I
can get the UPS to switch off with upscmd load.off. So the UPS can be
controlled. Here is my SHUTDOWNCMD:
SHUTDOWNCMD "/sbin/shutdown now -P"
I also tried:
SHUTDOWNCMD "/sbin/shutdown now -h"
I found this script in /etc/init.d/nut and changed the paths to upsd and
upsmon and used it.

Since I do not have much knowledge on how the Linux system boots and
shutdown I have spent the last several days searching for how the scrips
/etc/init.d are supposed to work but every thing I have found is a
little different than what I find on my Ubuntu system. Does this script
ever get called with poweroff?
