Wow, this could be a real bugger to find for the electrician… When the starting torque required is very close to the available rated starting torque of the motor…in otherwords the motor is available torque at selection was so close to the load requirements…and as soon as one drops this available torque for the motor […]
So Mr. E. came back from the auction with a old “new” machine. Placed in the workshop and looks around for an electrical point to connect the machine. Ahh, here is one closest to this electrical board. Oh damn, need a circuit breaker! Excited for the new machine the electrical holesaler gets called.
Is it the product causing the pollution they are talking about or is it that the product is limited to these environments, I don’t know? You check it out: ===>>>>>>>>OOPS…TO CONTINUE READING PLEASE LOGIN/REGISTER……Login button on top.
Shooo, another relay revelation I never expected…operating temperature 52-55DegC just with the coil powered. “Our products are designed to safely work way above the rated values”, the manufacturer says.
Before the arrival of space consideration for a panel the obvious is always done: Space for wiring and other compnents that might be added Environmental conditions that determines the qualties of the panel for instace what IP rating it has to conform to. But what does one have to consider as minimum requirements for the […]
It is a test button to confirm the operation of the earth leakage… “Duhuh (or something that sounds like that)” he says…I can see that…it is written on the unit…I ask what does it do. Does it push a lever inside and trip the unit mechanically or does it test it electrically as well…what does it […]

What does a star/delta starter do: Imagine a connected big hosepipe and the tap is opened – the full pressure will be available(delta), but what if the pipe is stretched such that the diameter decreases and the pipe grows longer…its the same pipe just differently configured.(star). That’s exactly what it is. When a motor starts […]
Hi guys, How many people know how to reset a circuit breaker? Just push it up you say.
Why did I not think of this… In another post I wanted to elaborate on the issue of a motor starting currents killing the generator so will it help to install a soft starter or might a star/delta starter be adequate? In the mean time I cannot resist sharing this trick: Since it is currently […]
Been working with star/delta starters for many years and not once did this cross my mind…I guess those were the days when energy conservation was not an issue. ===>>>>>>>>OOPS…TO CONTINUE READING PLEASE LOGIN/REGISTER……Login button on top.
