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.

• Pick your features: Models come with either a recoil handle (similar to a lawn mower) or electric push-button start, and one or more outlets to plug in extension cords. Some include covered outlets, illuminated control panels or automatic shutdown in case oil runs low. Portables can weigh from 100 to 250 pounds, so you’ll want to buy a wheel kit. With the wheels installed, a generator can be rolled like a wheelbarrow into place.

For the sake of simplicity in this example, assume the objective is to select a low-voltage dc disc MOV for the following circuit conditions and requirements:

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.

my first “real” job was in a video game arcade back in the 80’s my boss was a really cheap prick that used to buy asian cocktail machines that were “native” 110V, with a 240V to 110V step down transformer wedged in where it would fit, my second day I was fishing out a 20 cent coin that had missed the coin box, I got “zapped” hard enough to blow my finger nail in half and stop my heart.

I’m a bit spoiled as far as AC load SSRs go, since I get IDEC and Omron puck SSRs from obsolete equipment at work, but always exercise due caution when I have to go shopping for DC load SSRs. Far too much fake stuff out there, masquerading as reputable brands, some to the point of ruining the reputation of the brand. (Fotek… For the longest time I thought they were only a Chinese brand, like the various Harbor Freight “brands” that they slap on their junk tooling offerings.)

If he ever turns his car on its side so that the car jack is pointed toward ceiling and plugged into the evse as shown, then I’d worry about it.

I have seen a 10cm hole blown right through the middle of circuit board. I have had many repair jobs that it’s been obvious that lightning has hit the overhead power lines, exploded parts, vaporised PCB traces. Non of these had any negative outcomes except having to repair the device or throwing it in the bin, generally the latter.

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”.

I would say however that relying on the relay coil is not reliable at all, and there are a variety of somewhat more accurate methods that I would prefer to rely upon.

You need to factor in the kWh you used within the week (along with the cost per kWh). This will give people a better idea of actual cost to power this vehicle 253 miles.
