It's all very well to mock like that, but I did not write the law.Ok. Fair enough.
So I/we will deduce that any old slapdash method can be applied for non-fixed electrical work.
That makes more sense.
And I'd like to invite you to tell us exactly which law(s) do apply to non-fixed electrical work, as I suspect there are none (no specific ones), and that is nobody's fault either.
