NEMA plugs/recepticles for future reference

 

Simplified

Non-locking

Amperage of plug/recepticle must have wire-gauge to support. That is, 50A plugs must have 6 AWG copper conductors or thicker, 30A must have 10 AWG copper conductors or thicker, 20A plugs must have 12 AWG copper conductors or thicker.

Ampacity of breakers must not exceed the ampacity of the plug/recepticle OR the ampacity of the wire.

If the McChicken sandwich's price increases tracked with the Social Security Cost of Living Adjustment, it would cost $1.32 in 2024 instead of $2.99.

Chicken, it ain't caviar

Charles Hugh Smith once noted that the COLA is bullshit. All of the things we don't need to survive drop in cost while all of the things that we need to survive go up in price.

The price per gigabyte capacity of SD cards gets cheaper every year. How many gigabytes of memory do you need to keep your body-temperature above ambient?

The cost of eggs and rice and beans and oatmeal go up.

  1. Been a while but some MickeyD exec once told the press they still sold a 15 cent burger ... adjusted for inflation.

    ShadowStats keeps track of inflation the way it was done in 1980 (last year of Jimmy's presidency). Running about 13%/yr last I looked. That's still probably lower than what affects us chickens down on the floor that actually buy things.

  2. "All of the things we don't need to survive drop in cost while all of the things that we need to survive go up in price."

    The things that matter SHOULD cost more in a true market driven society.
    The things that don't matter.....simply don't matter..... and are therefore worth less.

    1. Baumol's Effect comes into play. Things like processing chickens is difficult to automate while making 128G storage devices and plastic injections moldings IS relatively easy to automate.

      Over time, the proportion of jobs that are low productivity (little assisted with automation) grow while high productivity jobs (which become more productive with automation) decrease as a percentage.

      Knowledge work is (now) very easy to automate. Macros, special purpose software (TurboTax, for example) and A.I. Even PLCs have self-teaching modes to optimize the performance envelopes.

      One solution that was presented was a hybrid work-force where all jobs were Modern + Agriculture.

  3. One "cheat" I remember from the code was welder circuits could be "derated" with thinner gauge wire due to duty cycle. Still used the 6-50, but ran #8 for the short run from the panel.

    1. I believe the code also allows for thinner gauge for “chassis wiring”. Short runs to connect components.

      The most significant heat rejection for “air cooled jumpers” in spot welding equipment is out the ends where it is bolted to water-cooled components

  4. Last night wifey says let get some KFC chicken. OK says I. Drove to the colonels outlet and look at the menu. Over fifty bucks for the big bucket. Tried to order at the window. Could not understand the mush mouth. Go inside to order. Can't order with a person, have to order through a kiosk. Items on kiosk different than menu outside or displayed inside. Can only pay with card, no cash, also no paper receipt, we are green. Get order, go home. Chicken different than order, coleslaw different, side of mac and cheese which was cold and tasteless. Never again.

  5. Were The Once And Future Resident and DOGE wise men, they would start presenting actual cost of items needed for people then and now and then ask have a discussion about cost cutting and inflation.

  6. Between medicare increase and social security COLA, I netted a whopping $2/month increase in social security. If I save that for a year I might be able to take my wife to a fancy dinner at "Taco Bell", to quote an old movie.

    1. It was not that long ago that they gave us zero COLA & that happened for more than one year running...

  7. Re NEMA plugs and receptacles: I help sell racks of computer systems and they mostly run on 220VAC power due to the high loads. When we start talking power requirements ask customers if they have high voltage to the rack yet. If they say no, I tell them "Tell your electrician you need 4 L6-30R power feeds installed. He should nod and give you a quote. If he asks what that means find a new electrician."..... "You are kidding, right?" "No, I'm serious, a real electrician knows what needs to be done."

  8. When working on electrical outlets there WILL be a test. If you failed the written test there's a chance you could fail the real world test....permanently. So study hard.
