How to Fix a Broken Air Conditioner | 25 Amp Circuit Breaker

Good call, light bulbs and heating elements don’t need perfect smooth precise 12vDC, as long as it’s in the ball park you’re good.

You are correct and if you design this type of solution you already know this. With PCB design, the alternatives are heavier copper, wider traces, plating up copper in the areas that carry heavy current or a combo of any of the three. But you can only go so far with these solutions. Hack apart a known good SSR and I bet they use the exact same solution.

I’m a bit disappointed, I thought this was a safe place for dangerous ideas. If you want to diy an ELV heat bed go ahead, but that isn’t going to suit everyone.

Having sorted out your bench, how about your tools? The chances are you’ll already have everything you need in this department, but it’s worth saying here. If you are using a tool or an instrument on a piece of equipment carrying electricity, it has to have the appropriate insulation properties for the voltage in hand. Perhaps you have to have experienced insulation breakdown in a cheap test probe at first hand to truly understand this point.

In the waning days of Flake’s presence in the Senate, the Arizona lawmaker, who’s frequently clashed with Trump, now has dwindling opportunities to make his mark. Longtime observers of his tortured reluctance to back Republicans going in a direction he does not like will recall that such stands often end with Flake simply, well, flaking.

I think every power MOSFET in my box, most of them from reputable sources, have packages rated below the die.

All of these ratings can be found in NEC (NFPA 70) Table 310.15(B)(16) in detail, but as an example, according to this NEC chart, a 6-gauge copper circuit rated at 90°C (194°F) has an ampacity of 75 amps while a 6-gauge aluminum conductor rated at 60°C (140°F) has an ampacity of 40 amps. Of course, there are other considerations in addition to this, but it is clear the rules of thumb we often use can get us in trouble if we aren’t aware that exceptions exist and what those exceptions are.

Coastal BC might be viable for them, here in the “temperate” bit of Ontario they’d be good in April and October.

A properly wired, properly functioning dimmer switch can get hot to the touch. I’ve found that a 65-degree temperature rise is normal for a maxed-out dimmer. If the ambient temperature is 71 degrees and a dimmer switch is at 136 degrees, I’d be concerned, but I wouldn’t report the temperature as a problem. I would, however, take an extra minute or two to figure out how many watts the dimmer is rated for. I’d then make sure there wasn’t too much being controlled by the dimmer.

PHEV is a lousy name for a class of cars, but what a good class they are. Most everything you say here could be said of my 2017 Ford C-Max Energi. It gets almost twice the MPG as my control car, a 2014 C-Max Hybrid. PHEV MPGs vary wildly according to your use patterns, but FWIW, mine is stuck on 65 cumulative MPG for its first 20,00 miles. At least half these days, I drove beyond the 20 mile EV range, and I drove over 100 miles on two or three days of the week, so I didn’t restrict my use to inflate my mileage.

I am glad, that finally someone posts this, because this is also my information about dangers of electricity. I just have not been sure enough, if I had missed something. I also heard, that a DC accident can kill you hours later even if you are not burnt that heavily, because DC is able to cause electrolysis in your body which upsets the delicate balance of electrolytes in your blood and tissue.
