Probably best to derate to 1.5x or 2x. But even then, are the “solder” conductors inside really going to be any different? Looking at then they appear to crate a conductor way bigger than 25A requires.

For example, putting 1 mA through a 1 MOhm resistor requires 1000 Volts. The current itself is barely noticeable and if it’s high frequency current you’re unlikely to feel pain – it’s just a funny spark that kinda tickles at your fingertip – but it’s still depositing 1 Watts of power into the resistance.

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.

Like many things, it’s the few psychopaths who spoil it for the rest. For most people, it’s quite possibly an emotional disability.

My 2 stage 23 x 24″ CASE snowblower I home-made converted to a 3 hp extension cord electric (240 on the Tesla outlet – peaks at 35 amperes and 7 1/2 hp). I was worried that I had underpowered it but last March when all the gas blowers on the street were stalling on heavy water laden snow, mine just kept barreling down the sidewalk.

I don’t think you can get multimeters that share the volts and amps socket, since the amps is usually a shunt to the ground terminal, very low-resistance, big and chunky high-wattage resistor. Volts is, ideally, infinite resistance, but not in practice of course.

There are lots of big name professional meters that share the same ports for both. My Klein shares them.

Don’t call at the end of the day if you want same-day service. After 4:30 or 5:30 p.m., I need to pay my workers overtime, so I’ll charge you more to make up for it. Calling first thing in the morning lets me fit your job into my day—and you’ll see a lower bill.

24v 12a is not that much more at 288watts. I’m sure I’m missing something to do with electromagnetism which makes the secondary unnatractive?
