Wiring an induction hob and two ovens on a single cooker circuit

[SUNRAY]

How did you get the homeowner to accept the cost of notifying for this new circuit? Given you don’t have current regs, what do you test against?

This was about 2 years ago and I was subbing to a company (as the vast majority of my electrical work is) after assessing the situation I called it in to the company and the boss came out for the inspection. There are several examples of that situation in my posts.

Just checked and it was still in effect until mid 2008. Apologies to Sunray.

My apologies too, for some reason I had it in my head I took my 16th in Dec 2008 and my brown book was new out, but it was all 4 years befor in 2004. So while checking the date I also read the definitions of fault and overload currents and my memory of those is correct.

I don’t come across any of the installations which are seconds from total failure he faces on every job. Then again up here we don’t see many AV engineers being called for electrical installation jobs.

Not all of my jobs are tricky, I don't give a report on here about every broken switch/socket or every successful PAT, 3 of us PATed an engineering company earlier this year with only minor faults found in the 2-3 weeks we were there, their welder cables certainly didn't look like this:

.
Not being funny but my fault finding skills are superior to some of the lesser experienced in the industry, this is not blowing my own trumpet, just a statement of fact with the age of qualified electricians being lower (or is that just me being an old timer) and I'm often asked to look at jobs after several others have visited and failed to find the fault. Classic example being this one: https://www.diynot.com/diy/threads/a-real-moan-tonight.552183/
I also tend to be asked to look at nearby 'just jobs' like 2way switches to save pulling others from the bigger jobs and to reduce travelling times.

Very often the best fault finders are those people can think outside the box of knowledge that they were given in their training.

Indeed, but that's just one example of a far more general phenomenon - that, in very many disciplines/fields, those who come up with the most innovative (sometimes even 'revolutionary' or 'game-changing') ideas, skills or practices often come from those who have not be formally trained in the discipline/field concerned.

When people are formally trained in any discipline/filed, they are influenced (even if only subconsciously) by being taught 'facts' on the basis of "this is what we have always thought" or "this is what we have always done" - and that can be a serious impediment to being able to "think widely outside of the box".

Kind Regards, John

Which is exactly why electricians don't make good controls personel. Yes it's a sweeping statement and wrong so many times but I can't begin to count the number of times I've built and installed a control panel and not been allowed to do the field wiring (not qualified). However being asked to repair the panel because it doesn't work usually results in reporting the panel works but the field has been wired incorrectly. One of those occasions I found a λΔ motor wired with 7 wires, 8 including earth and the 7th had picked up neutral from a random point in the panel.
The number of times I've found a 3 pole local isolater for the 6 wires required is countless too.

That's actually the opposite of the phenomenon I was describing

What I was suggesting was that, in terms of ability to "think out of the ('per training') box", an electrician might be more able to do that (in relation to control issues) than could a 'controls-trained person' - and, conversely, that a controls person might be more able to "think out of the box" about electrical matters than could a "trained electrician".

I must say that I'm rather surprised to see you writing what I quote above, since it seems to imply the corollary (that control personnel don't make good electricians) - which seems to be the opposite of what you have been suggesting about yourself!
