Pioneer debuts three new wireless CarPlay systems | 25 Amp Circuit Breaker

This hack is ridiculous and a hazard. The NEC bans the use of MWBC’s that don’t use a common circuit breaker tie-bar. The tie-bar causes both halves of the 240VAC circuit to turn off incase of an overcurrent condition.

An emergency isolation switch. Santeri Viinamäki [CC BY 3.0], via Wikimedia CommonsYou will be familiar with emergency isolation switches if you have worked with large machine tools. A big red switch designed to be easy to hit to turn all the power off. You may want to hit it if something gets out of hand, or someone else may want to hit it for you to turn off the power that is electrocuting you. Either way it provides a very quick way to manually make any mains sources on your bench as safe as possible in the event of an incident. Remember the bit we mentioned earlier in about sitting on the end of the line twitching until the power is turned off? This is the big red switch that makes it very easy for someone to do that for you.

PS I understand L1 will work for many people (up to maybe 40 miles per day driving), I disagree that it should be encouraged due to safety concerns and most general people won’t properly care for the L1 charger.

So the 12 / 24 V designs aren’t an illusion of safety, they are safer if you accidentally short yourself to them

I’ve spent four to eight years in apprentice school learning how to plan, install, inspect, and repair electrical products. Don’t insult my intelligence by implying otherwise.

But it’s not clear just how aggressive Flake is willing to be. On Thursday, he withdrew his opposition to a judicial nominee for the Eighth Circuit, a move he said was to balance out the absence of Sen. James Inhofe (R-OK), who was called away for family reasons, according to the Washington Post. Senators sometimes do this, as Sen. Lisa Murkowski famously did during Brett Kavanaugh’s confirmation when she withdrew her vote and was marked as “present.”

Still, most capitalists, when you order something, don’t ask “what do you want it for?”, so they can substitute something else without telling you. Generally in contracting with capitalists, mysterious “problems” don’t regularly as clockwork pop up, increasing the cost above what was agreed.

@ [Martin] DC can kill you hours later because it goes through your body like lightning, it takes the path of the lowest resistance (usually the most moist path) and cooks everything in it’s path including vital organs.

So it’s the usual forgettable Toyota – but still hugely preferable to the godawful Prius which is a truly horrendous looking vehicle 

Just reach for the “Flame Wrench” while working on a press, in a corrugated box plant. Within the next two minutes, you’ll know how many fire extinguishers are in that building. Box dust and the old, grease based, Letterpress ink was always a major concern when you were doing the repairs and needed to use a grinder, torch or welder, etc..

Generally, most LED power supplies are a constant-current type, and are often referred to as LED drivers. These can be purchased as off-the-shelf assemblies containing MOVs to meet lower-level surge requirements.
