Traditionally we would use contactors, the workhorses for electricians – but the new age has brought us a wide range of solutions when it comes to changeover systems. Ps: Much of our posts is a work in progress so if you would like us to participate in a possible candidate for your solution…let us know…will […]

Imagine the power to the building failed…stranded you are. So you go out and purchase a generator but how to connect this to the building…such that when the mains power does return we can switch back to mains power. ===>>>OOPS…You are not logged in for this group!

Why do I need a generator controller? Let’s cover the basics first: What is the thing we call a “generator” anyway? We know it is an alternative electrical supply source, right! ===>>>OOPS…You are not logged in for this group!

In an enclosure…do I use an isolator or a circuit breaker? Sometimes it gets confusing as what shall we use as the mains switch for a DB or electrical panel/enclosure: – Do we use an isolator or do we use a circuit breaker? Let’s just throw out a few common-sense pointers:

  What is this IP rating really all about? (all) IP = International Protection Rating. It’s a cool coincidence that it could stand for Ingress Protection – for that is what I suspect most of us remember it by. My simple definition is:- A measure of how sealed ANY product is in terms of solids […]

I promise you will never forget this any more! kW = voltage x current x pf We say the better the power factor i.e. the closer to 1 the better… So: Say 34.4kW= 400V x 100amp x 0.869(pf) Say 40kW= 400V x 100amp x 1(pf) – You get more kW with bad power factor…or do […]

Nice anecdote to explain PF in electricity. 

You did know electrical equipment has differing current ratings at different voltages, yes? ===>>>OOPS…You are not logged in for this group!
