If I want that, why wouldn’t I buy Toyota/Honda?
Either way, your scenario of a multi outlet branch circuit on a 20A outlet would also not be correct. Let’s just make it simple: 20 amps of solar gen and 20 amps of power gen, connected as follows:
Panel -> Breaker -> Solar outlet -> hairdryer outlet
The current would flow from the solar outlet to the hairdryer outlet fully, and the measured current through the breaker would be 0. All wires would be at 20 amps and therefore safe. (Lets ignore that 20 amp wire is only rated for that temporarily… continuous draw would be 16a…) No violation of any current limits and no danger.
Now, you could go crazy and connect 30 amps of solar and 30 amps of hairdryers and that would be dangerous, but we’re rapidly getting into the realm of incredulity. As soon as you removed the load/hairdryers you would pop the breaker.
Circuit breakers trip bidirectionally, so the circuit breaker itself would protect if too much current is drawn through to the mains panel.
How, precisely, would you get 65A through the wiring on this 40A circuit, if I drew 40A of consumption and had 25A of supply?
The 25A cancels out the 40A, so the upstream feed would only see 15A total. You do get 65A of total current drawn through the breaker panel, which is a concern, but the supply wiring would not see 65A. Subpanels (which, this would be a subpanel if it only had 40A capacity) are typically going to be just fine.
This has very little to do with the power meter itself, and more that the power company wants to be able to monitor if the meter is 'running backwards' (i.e., if power is flowing out rather than into the meter). Older meters could only run in one direction.
> Clearly some people think of it differently if they're plugging generators into wall sockets to power the whole house, dumb as that may be.
There's frankly nothing wrong with this if you do it properly. The 'proper' way would be to have a generator input socket near the main breaker panel, and the main breaker is interlocked with the generator input (i.e., only one can be on at a time). You absolutely can just plug a regular generator into a wall, assuming you aren't overloading the wiring or breakers... the safety issue is overblown. The reason why it's 'super dangerous and bad stuff will happen' is because people are stupid and forget to turn off the main breaker. Which, admittedly, is a reasonable concern because... people do forget.
20% is 20%. Unless you're moving from one tax bracket to another on a particularly steep threshold, a 20% raise is going to actually translate to close to 20% extra take home, especially at the income levels for someone making $3k/mo take home.
Health insurance yes, retirement… no, not really. They may offer a 401k plan and some might even offer a match, but most companies offer at most a 4% salary match (dollar for dollar, or sometimes 50c per dollar).
So, it’s a vehicle to invest retirement funds with some tax advantages, but it’s not really “providing” it like you would subsidized healthcare.
Usually that's the hottest part. And it's also the area most likely to be damaged by the excess heat: the power electronics
> Ah, that explains your stance. I definitely don't want fans that have them enclosed. Something like this is fine:
That example would be considered to be considered an enclosed luminary, actually. The bulbs are facing downward and the backside is enclosed by the glass/plastic globes which trap heat. You'll get more airflow than the fully enclosed ones... but it's still much worse than an open air bulb (or, bulbs where the bulbs face upward), and the place where you screw the bulb into the socket is going to be the hottest point since convection causes the heat to travel upwards.
Also, generally, the more modern designs have an enclosure because it spreads light out with the diffusion of the globe. You can use ring LEDs or other various patterns more easily that way.
Depending on which one you mean in the article… the super gaudy ones with extremely custom light fixtures would be hard. The basic led based that have crazy fan blades? Yeah, no problem.
Here’s an example (there’s a million like this in a variety of sizes, lumens, and color temps, just the first example I found on Amazon): https://a.co/d/0aP9nKdJ
> LED bulbs shouldn't cook. I'm not talking incandescent, but LED bulbs. I use them all the time. They last a decent amount of time.
But they do. They’re obviously not as much heat as incandescent lights, but if you’ve ever felt an LED bulb after it’s run for awhile, they’re typically too hot to touch. And fan enclosures are very harsh environments: no airflow and fully enclosed typically.
