It’s still dangerous though. Cost of a 12V power supply vs a small chance of killing myself, I’d spend the money. 3D printers aren’t cheap anyway, why economise on safety?

I am certainly not suggesting HVACR techs engage in performing work outside of their skills or licensures, but, in many cases, being able to identify the problem and making the repair are two different things.

If you’re worried about activists using media to promote fear and doubt about science and medicine,you’re in the right place. At Science 2.0, scientists are the journalists. with no political bias or editorial control. But we can’t do it alone so please make a difference.

You did reply to the Gurubuckaroo comment, just a few interjections managed to find their way in first. Does mess up smartarsed replies occasionally, shame when it’s a particularly funny one. On busy articles, I often find posts popping up between pressing “reply” and “post comment”.

You don’t need a big contactor to switch 1A at 120v, you can get little “ice cube” relays that switch up to 10A at 120V and they have a plug-in base so easy to change out when they inevitably fail. Most of them, in new perfect condition, make barely any sound. Nothing compared to the noise of fans and stepper motors. The only issue I can see is running AC mains voltage through wiring that is going in parallel with low voltage. Would need to use thick jacketed, shielded cable to prevent too much EMI. Maybe it’d be better suited using a separate transformer just for the heated bed, rectified/regulated but still a higher voltage for better efficiency. Speaking just from my experience as an electrician and hobbyist level electronics/3d printing experience.

FR4 is actually quite a good insulator. It’s only real failure is when you have impurities on the surface of the PCB in very high humidity conditions. The impurities will cause the surface tension of the water molecules in air to lower and as this happens the water will condense onto the PCB. The water on the PCB reduces the effective creepage clearance and can cause a flash over or arc.

It’s impossible to know whether to recommend the new Corolla yet, because no prices or specs have been revealed, although the argument in favour of the latter looks certain to be bolstered by a greater than average amount of standard equipment. In particular, the active safety roster, which includes the ability to apply the brakes if a potential accident is detected at high and low speeds, is far longer than most.

I had my poke. Mostly people saying “may” or “could” invalidate your insurance and advising caution. Which is sensible enough. Also mention of laws mandating a professional installing things like new wiring for cookers, and other kitchen / bathroom stuff. Makes sense since there’s water about. This is the UK that I looked up, since that’s where I live. Our electrical standards are pretty high, mandatory ring mains, limits on spurs and wiring length, and even our mains plugs have half a dozen safety features built in (protection against the agony of accidentally stepping on one not included).

Samsung is rolling out an update for its 2018 lineup of QLED TVs that enables FreeSync, which allows for smoother gaming without screen tearing. The company talked up its partnership with Microsoft’s Xbox division during its unveiling of this year’s sets, and this is yet another feature that embraces the capabilities of the Xbox One X.

The third incident was also while I was working for the welding repair company. I had a previously perfectly working high-pot tester and needed to test the insulation on a transformer. The tester itself failed and shorted to the case – and I took 11kv AC to the fingers just by turning the power on. That stung a bit, but I got a new high-pot out of the deal, so a net positive.

Such an awful practice and terrible idea. I have an EV and would never do this (me being an EE). I decided to make this correctly and I installed dedicated #10 cable from the auxiliary power distribution box to the EV charger as a permanent connection, no plugs no unsafe contraptions, and following all the NEC codes. Those cables you used and the crimp terminals aren’t suited for the current rate. Check them if you don’t believe me. Crimp pressure plug in terminals are rated for around 6 amps of continuous AC current and I hope you used at least 600 A.C. volts insulation cable… Bad, bad idea.
