We are going to use an industrial enclosure that housed Programmable Logic Controller (PLC) Power Supply Units (PSU), relays, and electrical bus strips. I've been calling this enclosure the PLC Case. After removing most of the components, I found that I had to remove a metal panel in order to unbolt the rest of the components. So, I removed the panel from the case, will finish removing components, and we'll decide if we want to continue with a metal panel that has to be drilled and bolted to, and if so, do we want to hinge it it so we can access it more easily. Or, we may want to replace the metal panel with a plastic or wood panel.

"We're very close to finishing our Power task list. Let's choose a panel material to mount most of our controller internal onto- stick with steel or switch to plastic, wood, etc. We can reassign power bus strips for 120 VAC, 24 VDC, 24 VDC, 5 VDC, and since we'll eventually have a computer PSU, +12 VDC, -12 VDC, and maybe tap the 5 VDC from it too. We'll wire up our fuse bay, and figure out what we'll use for switches until we put the panel back into the enclosure that currently houses the toggle switches. We may want to install a power strip with breaker onto the panel, so we can get 5 VDC from a small adapter while working, and have the ability to plug in other PSUs to it as we work. We may even want to keep the powerstrip for when we reassemble the enclosure.

A revised, multitask plan might look something like this:
