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!

There are many who has answered this question before:- Most say relays are JUST smaller brothers of contactors. Others say:- Up to a certain amperage (30/40Amp) it is a relay and beyond that it is a contactor. Others say:- In the construction, the relay coil sits on the side and a contactor it sits in […]

Why so many names for the same thing? Are all switches rated as load break switches or as isolators? In other words, if you see 10A – and that’s all we got – can we use this as a load break switch? Or is there even a difference? Linguistically switch will refer to anything with […]

I presume you are aware of this nice solution to take a normal relay, get the right base and one can turn it into a timer… Well, one day I get a call:
A customer wants to install a current monitor to monitor a motor and is convinced it will not work with a star delta starter. The startup time is too long, by the time delta pulls in it would have tripped. What now? ===>>>OOPS…You are not logged in for this group!

Selecting the right relay for the job…Between relay manufacturers with the type and characteristics – can one take for granted the relays will be able to do the same job. If you bought a cheap relay, make sure you install and use it correctly…otherwise you can kiss it goodbye in a short while… Bought a […]

A relay SINGLE CHANGEOVER DIL(Dual inline) RELAY might be rated for some amperage but it does not mean the bases SINGLE CHANGEOVER TERMINALS qualifies… Now you know what I am talking about

The relay requires an auxiliary supply to operate the electronics then we are going to connect the current “reading” phase to the current measuring input terminals. These might or might not be isolated from each other… ===>>>OOPS…You are not logged in for this group!
