If you have no idea how electrical circuits work, or what people mean then they talk about volts and amps, hopefully I can shed a bit light.  I’m intending...

The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.

Capacitors have numerous applications in electrical and electronic applications.  This note examines the use of capacitors to store electrical energy....

Just added a page to the tools, which will allow you to calculate the synchronous speed, slip and rated torque for an induction motor. Not a particularly...

Many questions sent in to the site are in connection with motor starting and in particular star-delta.  For all but the simplest application, there is...

A couple of months ago I came Microsoft's OneNote and downloaded the 60 day free trail. Since then I have been using it regularly and now have a full license...

Steel ladders, trays and baskets form the backbone of cable containment systems. Often these items need some form of surface treatment to prevent corrosion...

When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...

Years ago I was told that you should always try to write the best report you can.  Many years later I still think on this as one of the better pieces of...
