The photo's & violation sections here have hazards obvious to us, and would require explanation in rationale, not dry code articles for 'layman' 'DIY' interaction.
I think we're in agreement here that explanations would be needed for better understanding. Applicable code sections could be included for those that would like to 'follow the book'.
Please keep in mind that this would be an area offered for informational purposes only, not interactive, and not in the form of How-To instructions. One of it's goals would be to promote safety and the value in having Electrical work done correctly by qualified and licensed/certified persons. I was hoping that it might be a good project that many would like to get behind and contribute to. We could use an area of the forum here to work out topics and related comments before they are presented elsewhere.
'Flying Splices' are a good example. Now we need a good explanation(s) of why they are bad (and applicable code section(s), of course). (and pictures)
