+## 2025-11-10 06:53 --- Monday Morning Before Work
+
+I've been trying to be alone with my thoughts more
+recently. It's almost bizarre how working in silence
+for an hour makes the thought of music or an audio-
+book seem overstimulating, It feels right, though.
+To want to converse with myself rather than let my
+superego be drowned out by appealing sounds or a
+fantasy story I've already heard, or obscure facts
+about a game I've never played and never will.
+
+I still relapse, of course, a lifetime (albeit
+a short one) of unhealthy interaction with computers
+will do that, but I'm making quick -progress.
+I watched a video yesterday that suggested that
+it might be my growing understanding of computers
+rather than my self discipline-that's lead to this
+change in the dynamic between me and them. That,
+in understanding _how_ they function, I've turned
+them from _devices_ into _things_, which lack
+the mystical allure of the former. Whatever
+the reason, it's good progress as far
+as I'm concerned. It feels good to be introspective
+and to have time to build skills people care about,
+like music and style and... birdwatching...

+
+A significant change from Ace to PDI in my mentality during takeoff
+is that I now tend to expect that (within reason)
+"holes" in takeoff scripts are _intentional omissions_,
+not holes in cost coverage.

+
+I was updating my notes,
+filling in gaps in scripts based on Joel's,
+when I noticed a strange paragraph:
+
+> [!quote] `OneNote`/`Joel Take-off`/`Misc. Notes`
+> Drop Down Ceilings vs. GWB (Gypsum Wall Boards)
+>
+> Drop down ceiling is technically "Exposed" (the real term should be accessable),
+> so Romex and SER is not permited. Will need to use MC.

+> > 1. In any dwelling or structure not specifically
+> >     permitted in 334.10(1), (2), (3)
+> > 
+> > 2. ==Exposed in dropped or suspended ceilings==
+> >     in other than one- and two-family and multifamily dwellings
+
+This analysis of 334.12(A)(2) is flawed.
+
+Based on
+
+* [[nfpa-70_100_definitions#Exposed (as applied to wiring methods).]]
+* [[nfpa-70_100_definitions#Dwelling, Multifamily.]]
+
+[[nfpa-70_334_nm-cable#334.12(A) Types NM and NMC.|334.12(A)(2)]]
+can be paraphrased as follows:
+
+> [!cite] NEC 334.12(A)(2), pp.
+> Types NM and NMC cable are not permitted to be installed
+> in accessible spaces above suspended ceilings,
+> _except in buildings containing one or more dwelling units._
+
+The prohibition of 334.12(A)(2) *never* applies to apartments or condos,
+And only applies to hotels and dormitories on a basis of AHJ interpretation
+(See [[multi-family-dwellings#Are Hotels Multifamily Dwellings?]]).
+
+It's unclear to me if this a misunderstanding
+or a [[heuristics|rule of thumb]] to cover the case
+that guestrooms are not interpreted to be dwelling units.
+If it's the latter, I believe it's far too conservative
+to be used whole-cloth on all estimates.

+
+### "Feeder"
+
+The NEC definition of feeder is quite strict.
+I'm certain I misuse it frequently.
+
+![[nfpa-70_100_definitions#Feeder.]]
+
+It _does not_ include power conductors to
+[[nfpa-70_100_definitions#Utilization Equipment.|utilization equipment]],
+those are a [[nfpa-70_100_definitions#Branch Circuit.|branch circuit]]
