And even today people give the advice of plugging a computer in the wall and grabbing the metal case as you’re working inside it. Bad idea – if the PSU has failed, you may very well have live voltages in the boards.

I’m certainly pleased the US Air Force along with the wind turbine industry taught me just a few skill sets in getting that Level 2 service expeditiously installed.

I heard from an instructor that some guys from the national power company use full PPE when switching on/off old main fuses in domestic installations (230V, 15 to maybe 60A). These things are fully plastic and can be operated by everyone, so no PPE needed, but it seems like they explode sometimes – maybe because of the dust you mentionned.

SSRs can actually contain what is used here: optocoupler+triac or they may use optocoupler+mosfet. Just like individual triacs you will find that they suffer from the same issue: high power dissipation. A quick looks shows BT137 will burn 20W to switch a 5A load, I see 6W for the first 10A SSR I encounter. This is too much to dissipate in a small junction box isolated inside a wall. Meanwhile, a 10A relay will dissipate maximum 2.5W through the 0.1ohm contacts.

Being in the controller business I’ve been presented more than one friend’s design with insufficient cooling. One friend even mounted his SSR to a decent heat sink then mounted the entire assembly inside his housing with no air circulation. His response was “it will work” and he’s had two SSRs fail that I know of. At least in his case, the steel housing kept the “magic smoke” contained!

McConnell, however, has said he doesn’t see any threat of Trump firing Mueller, and he indicated Tuesday that he would “probably block” the bill from coming to the floor if Flake pushed it a second time. On the other hand, Majority Whip John Cornyn has previously signaled that there could be an openness to considering the legislation to keep things moving on judicial nominees, especially as the Senate seeks to wrap business up toward the end of the year.

Turns out my old GTX670 draws a lot more power than my new GTX1080 and, based on napkin calculations, brought my total power draw a bit too close to my 750W PSU’s limit. (200W CPU doing me no favors…)

I’ve been bit in a big way only three times. Two of the three were “Trust but don’t verify” issues, and I learned from them – always verify, no matter what anyone says.

• 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.

It’s *mostly* read-only. They usually have a LED for power-on indication. You could stick something to the front to detect that, if you needed a response. Tho for things like lights, usually the user will press the button again if they don’t come on the first time.

Not at all. One lumberjack pushes while the other pulls, and they’re both pushing and pulling against the ground. It’s fits perfectly.

A lot of times these days, it seems like we hackers are a little like kids in a candy store. With so many cool devices available for pennies at the click of a mouse, it’s temptingly easy to order first and ask questions about quality later. Most of the time that works out just fine, with the main risk of sourcing a dodgy component being a ruined afternoon of hacking when a part fails.
