Everyone familiar with wiring knows what an electrical box is. Most
of them are square or rectangular shaped metal or plastic boxes used
for outlets and other devices. But what about the round ones, mostly
used for light fixtures? Those are NOT "Boxes". The term "BOX" means
a square or rectangular shaped enclosure. A round object is NOT A
BOX. Boxes are NOT ROUND !!!!
Why do electricians refer to those round ones as boxes, when they are
not a box and are not box shaped? I've heard the term used as both
"round box" and "octogon box". Yet they are not boxes........
This is false and misleading terminology.
The companies that manufacture them, define them as boxes. The 3" and 4"
round boxes were originally round, but because connectors and locknuts
didn't make good contact in a round box, the NEC outlawed round boxes, and
they became octagonal. Many people still use the original term "round box"
Shallow pan metal is round. Plastic ceiling light boxes are round except
for the stud flat.
Who cares if it's not round? It's the terminology and everyone knows
what each other is talking about.
If you take a pencil and run a mark along a rule on something, then you
draw a [what?] on it?
Most might answer a line but that's incorrect according to some geometry
teacher I had long ago. It's a line segment. A straight line goes on
forever in opposite directions.
Everyone calls it a line. Once again, who cares? If I run into my dead
geo teacher, I'll toss in the segment part.
I guess that's true. Digging back through ancient memories... a straight
line has a fixed slope. Equation for a straight line is y=mx+b where m
is the slope. The first derivative of an equation is the slope of the
curve at a given point. If you call the line a curve then the implied
exponent of x is 1. First derivative is 1*m. Since m is a number, the
first derivative is the same at all points along "the curve".
Why can I remember this crap from decades ago but have no f'n idea where
my keys are or what I actually sat at this computer for in the first
Be glad you can. I used to solve quadratic equations in my head; now I
wouldn't even recognize one if I saw it.
On the positive side, I still vividly remember all the young ladies from
50-60 years ago :)
It is a syndrome that comes on at the point in life where one has gained
wisdom, learned the secrets of the universe, and just doesn't consider
trivia like "where are my keys?". :o)
Why is it I ALWAYS know where my husband (x2)left his keys, but I cannot
find my own keys when I KNOW they're in my damn purse?
