Content of Core Electrician Courses, how do we change it?

I come from an Electronic/Electrical test background rather than Installation. In the last couple of years I have started teaching Electrical Courses for students wanting to be electricians. 

Looking at these courses  it does not look as though they were ever designed for electricians. Rather that they were designed by academics and engineers with degrees, who simply did a cut down version of their own courses to make up something “suitable” for electricians.

Be it EAL, C&G or BTec there seems to be a great deal in the courses which is totally irrelevant to being an electrician, at the same time there is much that is either omitted or given such a brief mention it is not adequately addressed in the curriculum and certainly not in the authorised course books to accompany them

A small sample of Items in the courses which are irrelevant or obsolete.

For example, atomic theory, electron flow, doping and depletion layers, how triacs, diacs, thyristors etc work. High and low pressure lamps of a variety of types Mercury, Sodium etc. Gears, pulleys, Left hand and right hand theories, details of generation methods. And identify and explain how a variety of different types of electric motor work.

A small sample of things missed out or barely touched upon,  

CAT ratings of equipment. Given that their life depends upon suitable equipment being used it is important that they learn about the equipment they use and its limitations. GS38 does not cover everything “test” by a long way.

Crimps are misunderstood and frequently done very badly, despite the range of crimps being used by electricians being tiny. Crimps should only be done with specific tools. The correct methods of crimp selection, crimping and crimp inspection should be taught.

BS7671:  421.1.1   Manufacturer’s instructions must be taken into account when installing. That means All the electrical accessories you buy will have Manufacturers recommended Torque settings for the screws.  Most students don't even know what a torque screwdriver looks like let alone how to set one or use a calibrator. 

Explain the different start/torque/performance  characteristics and lifespan/reliability of electric motors. (something of use, not how they work... but what they can do).

Also needs much more emphasis on test and fault diagnosis, and methods/tools/techniques of fixing safely and cost effectively.

I could add much more to both of these lists, but this is getting long now.

The Resistance to Change

The problem is that the examination bodies have a modular set of course elements which are the building bricks of a variety of courses. I think they are afraid to change things, becuase customers can be reluctant to see change, or at least, that is what the exam boards claim. They are also afraid of "knock on effects" if they change a module on one course, or the impact on others. But I think the course criterion are now well out of step with what is required, and the authorised course books even more so.

So I start with discussion with.... What else needs changing, and who do we contact to get things changed? 

Who will be first to update and create better modern standards? EAL, C&G or BTec?

  • I am so not sure about dropping 1st principles and diluting down the teaching of electric motor theory. By all means re-examine stuff which is obsolete but do not remove the building bricks and replace them with sand.

    When I did my C&G 200 series course back in the mid 70's we had the 1st year full-time with broad-based training based on the old EITB model. Some of this was effectively redundant. We were taught about Ward Leonard set-ups, D.C. Faceplate starters, some of which were still in use in the local coal industry. We were also taught about intrinsically safe installations too.

    Where I used to work we had 2 old Butler horizontal planers with 20ft moving beds. These were Ward Leonard set-ups due to the finer speed control you got back then with D.C. motors. No IP protection in panels back in those days. The machines dated back to the 1940s when the place was set up as a shadow factory for the war effort, so lots of live D.C. stuff to brush your tender pinkies on if you weren't careful.

    Faceplate starters? Never ever saw one in the wild. Intrinsically safe installations? This was aimed mainly at coal mines rather than petrochemical plants, and since this wasn't the sector I worked in, I never had to deal with one for real.

    A.C. Theory, magnetism etc were useful when it came to applying knowledge gained through hands on experience. I did the 1st year 'Technicians course' (T1) in parallel but found it staid. The only processor I leaned about apart from resistors, rectifiers capacitors and transistors was the 555 timer chip. Again, of very limited use. Back then, if we didn't know what a chip did, we just unsoldered it, replaced it with the correct I.C. socket from RS and kept on swapping chips until we got a piece of kit working again - photocopier engineering style. Most of the time we never really understood how we got something working again!

    So, even back then, there were redundant legacy anomalies still being taught, even if hardly relevant most of the time.

  • Examining the wiring diagram of a face plate starter involved investigation and the theory of how it works. Useful stuff.

  • It would not be building on sand, rather building on what is relevant. This is all the more important now that many of these courses run on much less than half the teaching hours they used to. Such are modern economic pressures.
