How power works in a data center: What you need to know | Circuit Breaker Parts

The U.S. benchmarks are approaching the unofficial start to summer amid characteristically range-bound, and slightly sluggish, price action.

Everything industrial is 3 phase though; it’s 240V phase/neutral or 415V phase/phase here though. You can certainly get a 3 phase connection to your house and/or shed though – it costs about $1000 to replace the meter plus a bit more for wiring – if you have a problematic power-tool habit like me.

The importance of inspection isn’t so much the wires popping off as heating up. Any signs of discoloration of the crimp terminals or wires, or any fog or smoke and you should disconnect *everything* immediately and stop using it until or unless it is repaired and ALL heat damaged components replaced and THROWN AWAY.

Oh, and if you want a car charging hack, there’s always the Hydra: http://hackaday.io/project/3939-j1772-hydra

No, ebay removed the ability for sellers to leave negative feedback years ago. Fun fact – the majority of an ebay sellers score these days (not the % positive feedback, but the score used for determining search rankings etc) is determined by the % of orders that are received on time and without a ebay ‘case’ (return, etc) being opened.

Meanwhile in my house (uk) we have a street lamp time switch with a single pole switch that looks like it was designed to handle 30A. It is beautifully engineered from brass that increases the on period as the days get shorter, I felt bad hacking it so that it would turn on my water heater for an hour twice a day, a job it has been doing for 17 years now without incident. Electromechanical is by far the best way for high current loads at any voltage as fatcas I’m concerned.

I to have worked with high voltage systems. My point was that it needs to be treated with a bit of respect or it WILL kill you even if not immediately. My friend was an electrician of many years. And sure, I hear lots of stories of how people get away with this and that, but that is just that they gotten away with it so far. They could be dead tomorrow.

This doesn’t make any sense, why not use an extension cord with the 220 already in the house? A 6 or 8 gauge cord for 75 feet should be perfectly fine.

If you do not know the exact value of each cost, you could enter an estimated percentage based on the cost of goods.

https://en.wikipedia.org/wiki/Electric_shock#Factors_in_lethality_of_electric_shock If the current can be limited to Less than 30mA or less people should live, see the graph in the above link. This is much easier to achieve with lower voltages because the human body resistance is higher with lower voltage shocks ( https://en.wikipedia.org/wiki/Electric_shock#Body_resistance ).

The customer changed their tune. My boss was impressed (though not enough to give me some coinage for ingenuity) and the electrician was told to change the breakers and add the new feeders to support the load. Got a lot of recommendations from that customer in the years after that.

The basic concept of your point is looney. Voltage doesn’t cause heat, The only thing heat dependent for a given installation is the current – of which 120 volt charging is usually less than 240.
