I don't think it should be. It never used to be wiring by numbers until we allowed it to become so with the birth of fast track training centers and domestic installation guides.
then you should blame the schemes and the operators of competent person registers for the decline of training standards rather than us electricians ourselves.
The way I see it, if you're going to install a circuit you need to know why you are doing it, why you are installing a specific size and type of cable, why your Zs needs to be below a certain level, what voltage drop is, what size cpc you need, the effects of electromagnetism, types of protective measure etc.... I could go on and on.
Rubbish , the OSG provides standardised domestic circuit details that require next to no additional design & calculation , thats why it exists.
The fact is, commercial and industrial wiring could just as easily become wiring by numbers if we let it, but does that make for a better standard of installer? No. Because the lack of underpinning knowledge, that core understanding of electrical science and principles is no longer there.
Its becoming like that due to the modular design of buildings and the systems contained within.
Clients want cost effective projects , they arent interested in hiring the highest skilled staff available just to screw unistrut to the wall.
I'd have thought you'd have grasped that basic econonic factor.....
It could even be argued that your average one man band domestic installer needs to be more knowledgable than your average jobbing commercial spark who does nothing but sling in SWA on ladder and pull singles through trunking day in day out. I won't make that argument, but it's there!
that arguement is about as sturdy as a house of cards in a tornado........
