Well myself with 5 year Engineering apprenticeship, night school a technical college. The degree in Mechanical Engineering followed after several years experience mainly mechanical design mid 1970's elected M I MechE and therefore CEng. Moved into industrial machinery control system design including PLC's and then Micro controller hardware and software design. The into application software design lats 25 years before retiring as just got tired of call outs, dealing with deranged customer and fixing system and trying to get employees to do the job I pay then for.

IMHO Engineers and Technicians are different kinds of people and as in my case I have been on both sides of the fence but this is not always the case as of course common sense died a long time ago as there we have it.

Just a point out, term CEng was instituted by the various bodies representing various Engineering professions to distinguish between technicians calling then selves engineers and those who have gone through extensive theoretical, practical training and practised their profession for a number of years and have attained a high level of expertise together with legal responsibility for the work they perform.

Do You think as the one man band business owner of a security installation and service company, I do not have any legal responsibilities for what I do, say, supply or advise?

With exception of a Molex Premmised Networks Certificate I have no formal qualifications I can show.. My alarm trade qualifications as an engineer were achieved with a company I left to many years ago.

As for technition I'm contacted by several suppliers to advise their clients (my competitors) over problems they can't resolve. I'm used as a 'bug killer' or problem solver by other installation companies both small and large in a consultancy capacity.

Like many trades or vocations today, compliance to regs for DDA, Data Protection H&S, Building Regs etc has to be incorporated. To do so you need extensive understand of all those and many other trades in how they work, on top of how your equipment will be best deployed, in compliance and ease of operation, while offering the maximum security, or risk being sued.

I appreciate and respect what you say about yourself. You have no idea and likely no interest in my abilities, suffice to say they extend way beyond wikipedia limited definitions..

like you have, I do have vast experience and knowledge in the areas I work in what I can and do which covers a vast spectrum of equipment inside out, . my right to be called both an Engineer and a Technition in my fields I fully earned to and treat dearly.

So we have to agree to disagree as I'm not writing out my full CV

I do appreciate you knowledge and experience, that is not in question. The usage of the term of Engineer is.

A C Eng or any other professional designation is personally responsible for the work he performs. In that if a C Eng designs a structure and it falls down due to faulty design and kills people, he can and will be charged with a crime in the UK that would be manslaughter. Where I live its culpable homicide but is the same. Here its up to 15 years in prison so it is very personal that cannot be circumvented by being employed by anyone else.

This is not quite the same as having to comply with regs like DDA, Data Protection H&S, Building Regs. Of cause you can be sued for not doing your job correctly as any one can but that is a civil matter not criminal which is very different.

Also have a look at this that talks about the Regulation and licensure in engineering around the world.

Not sure why I try, but here goes,

You have a classic case of emphasising points taken out of context to make your own seem overruling..

To wit, see the bits //. // as I can't underline in here on my ipad.

Wikipedia is not as shown the law, playing barrack room lawyer based in its ambiguous quotes is stuff of crapp tv like Perry Mason and Cavana shows, would you in all honestly dare go to court starting you prosecution with "M' Lord, according to Wikipedia........" - Really?

"As with many other professions, the professional status and the actual practice of professional engineering is legally defined and protected by law //in some jurisdictions//. Additionally, //some jurisdictions// permit only licensed engineers (sometimes called registered engineers) to "practice engineering," which requirei careful definition in order to resolve potential overlap or ambiguity with respect to certain other professions which may or may not be themselves regulated (e.g. "scientists," or "architects").

That's not across the board, in this country, btw there's no chartered achitects according to Wiipedea then - that means those who claim to be fraudulent fakers? You really could not make this up!

Relatedly, jurisdictions that license according to particular engineering discipline (that's not the UK then) need to define those boundaries carefully as well so that practitioners understand what they are permitted to do."

Nearly all the paragraph blows your own ideas of being an 'engineer' or 'technician' clean out if the water. I do not while in this in country need any documentation to be called an engineer within the fields I work in. I don't build or design bridges or aeroplanes or in fact anything hazardous

where we in Austrlia you would a legal case, as it is - you don't, or have the right to challenge me or anyone else to be engineers, while of course you welcome to have a personal opinion - your not legally qualified to comment yet you seem to adore exacting fanaticised version of rules using Wikipedia as your misread proof reference's to be imposed on others.

My point is that my definition is t "An engineer is a professional practitioner in various disciplines of engineering"

Not some one but installs various bits of kit and fixed faulty bit of kit.
In the USA and "engineer" is some one who drives a locomotive (train in the UK) this is far different to what my definition of an Engineer is which I give above but you just don't get it so I give up an pls stop the insults.
 
Now I get it, you 2 are from different countries.
The definition of engineer is different the world over. Try going to France, everyone that isnt clerical is an engineer.
 
Roger, If you decide challenge people using a Wikpedia as your knowledge base for validating your version of reference terms, then to describe others, especially long practicing specialists, using Wikipedia, do you not realise to prod engineers you don't even know it is extremely rude and insulting.

If you want to play Mr Superior Poe face expect strident 'returned fire'.

point is that my definition is t "An engineer is a professional practitioner in various disciplines of engineering"

To be polite, and what exactly is it in that starptement that has to do with the price of apples?

I am a professional practitioner in many various disciplines, alarms, access control, door entry, CCTv, CAT5e/CAT6 networks, computer configuration, network set up configuration and fault funding, private telephone systems (both ISDN and Analogue). On top of that I design, construct and produce many items to make noticeable corrections if others designs and improvements. If you add in the various tools I use, the materials I work with, I think I qualify.

I can't go into deep details here for contractual privacy reasons, let's say I've worked sub-contract for several large corporations and produced and effected solutions that others simply could not achieve.

That is not just sticking boxes on the wall and plugging it in, to call myself a technician' I'm Notjust installing various bits of kit, swapping the occasional battery to call myself a 'service engineer'.

"In the USA and "engineer" is some one who drives a locomotive (train in the UK) this is far different to what my definition of an Engineer is which I give above but you just don't get it"

Because your definition backed up Wikipedea holds no supportable value in this jurisdiction/country, but you still decided to keep using for validation to state I and others like me are not engineers - simple as, do you not see the blatant rudeness and insult in that?

A person who makes a pushbike un-aided is an engineer, a guy on a work bench servicing a lawn mower un-aided is an engineer, neither have to have a certificate to do so.

A woman giving birth is likely not trained in that act, or an engineer with oligy's, but still produces miracle.

so I give up an pls stop the insults.

Best you start in by showing true mutual respect instead of uttering tinpot statements is my advice.

You are correct Engineer does mean different things in different countries.

Don't know where Mr Dayz is but this is my background.

I grew up in the UK (Birmingham to be exact) and did all my education and training in the Birmingham area including 4 year part time B Sc degree at Aston university and practised mainly Engineering design in various engineering companies in the UK until I was employed by a South African company to design and project manage some major mechanical plants in South Africa.

I then stayed and started my own control system design and manufacture company, finally ending up with a software design and support until I retires at 64 years of age 5 years ago.

I am sorry but I think Mr Dayz just does not what a Professional Engineer dose like a lot of people but no skin off my nose.

Or a footballer ��,
Born in East London, left school at 15, went into the motor trade, head hunted by The Bus company Garage at Barking, but did not want to work on large vehicles or do shifts. Could have got an aprentaship but money was only half I was already earning, was going into airforce when future brother in law suggested I try alarms. - suppose I'm still trying it out @ 67 because I can't be concidered as an engineer - apparently.

Fell on my feet really, as while the economy is good people want the luxuries like video door entry, in a recession they want alarms and CCTv. so work is always busy giving a decent standard of living technology is always changing so keeps interested.and totally enjoying it.

Working for myself I have given two sons a trade and taken over 20 people of the long term dole and taught them a trade, some went on to other companies to be managers, one eventually a company director, all are still friends.
