Larson Electronics LLC Releases Portable 75 KVA Power Distribution Station with 2 520R-GFCI Receptacles | Lrd12 Overload Relay

Don’t describe the kind of ceiling fan or light fixture you’re looking for and expect me to find one that fits your vision perfectly. Go to the hardware store and pick up your own items so you can guarantee they’re what you want. Just get in touch with me before you buy it in case it won’t fit correctly. Plus, find out what electricians wish you knew about batteries.

I definitely knew at the time touching bare wires wasn’t a good idea, especially not good to put yourself in a circuit, and have no idea what came over me at the time. Likely my fortune came from the fact I was in series with 20 odd low brightness bulbs so didn’t get to enjoy much current. No humans were harmed in this odd experiment.

They’ve lifted 200kg so far, and it looks like a pretty cool addition to a shop already packed with other builds, like their MOT spot welder and a propane tank sandblaster.

Usually called a Residual Current Device (RCD) or Earth Leakage Circuit Breaker (ELCB). Usually set on 30mA, but they take a small time to trip, which is dependent on how much current is leaking into the poor unfortunate 3D printerer. Much better than nothing, but not 100% guaranteed to save your life. I’d sooner leave mains voltage alone for things I’m tinkering with. I only mess with the mains for simple jobs, and then I’m very cautious.

Note: Not all certifying agents offer online lookup, and some have a lag time for posting new certificates. If you are unable to find a certificate online, contact the certification agency or supplier for further verification.

I’m not remotely an experienced sports shooter, so I can have trouble tracking fast-moving subjects under the best of circumstances. Already finding tracking fast action closely challenging, I found tracking fast action closely based on a series of static images delayed by 1/10 second or more was quite a bit harder still. After a little practice, I got better at doing so, but I sometimes found myself resorting to tricks like keeping both eyes open while shooting, or shooting in short bursts and using the time between bursts to get the subject properly framed with full-time live view again.

I have to say up front that I’ve never been a fan of EVFs. While they do permit much more information overlay than conventional optical viewfinders, I’ve always felt that EVFs’ limitations have outweighed their advantages. In particular, EVFs usually have limited sensitivity and dynamic range, not to mention low refresh rates and poor resolution when compared with the view through a conventional optical viewfinder.

Remembers me of an incident when my mother asked me to fix the extension cord for the electric lawn mower – “please check the cable, the garden worker complained the mower does not work”. I opened the socket type end of the cable, saw a dislodged contact spring and wanted to reseat it. Then I had to feel the other end was still connected to 230VAC mains. It just did not think of thisbefore… But luckily it just stung a little. I pulled the plug and continued my work.

The nostalgia for “classic” miniature consoles isn’t ending anytime soon, either: Sony just announced today it’s making its own PlayStation Classic console. The tiny PS1 will come with “20 genre-defining titles,” and it’s set to release this December for $99.99. Also coming this winter is the Sega Mega Drive collection on the Nintendo Switch, and the trailer for it was published today.

In the case of Chinese relays and SSRs I double the amps and add 10% …. Ditto for Chinese switching regulators which put out everything but DC after they reach about 50-60% of their rated load
