"No person shall be engaged in any work activity on or so near any live conductor...."
"Any work activity" clearly includes testing, so if you are right then people should be using a permit and risk assessment system involving at least two other experienced people in order to do an EFLI test.

Paul, just checked the regs because I had a suspicion you were correct, but you're not.
What you say is true for the 14th and 15th edition regs, but it has been dropped from the 16th edition (mine is dated 2004) and 17th edition regs.
Hmmm.... O.K., I hadn't realized that had been changed in the 16th edition so I stand corrected. I wonder what prompted the change? I should have noticed it when studying the table again on my comment about identification with CTE 110V.
Nevertheless, an older install could have blue & black as a phase C feed to a single-phase sub-panel. Maybe room for mixing it up with dark/dirty brown & blue on a new install?

Speaking of which, who remembers that when we adopted brown & blue for flex the original specification was for light blue? Early flexes to the new standard did indeed use light blue, but over time we seem to have had increasing quantities made with much darker blue.
The same goes for cables and accessories for fixed wiring. I remember looking at a newly changed meter and installation a year or two ago, and a first glance in less-than-perfect light I thought the installer had actually used brown and black for the connection. It was only when I looked more closely that I realized that what I had first thought was black was in fact very dark blue.
I've seen both ways, although red & black for all probably has the edge.
But either way, I think we're agreed that the changes have left one big mess behind. With the official changes plus the confusion which has arisen since, maybe we should have a new CU sticker warning that any color may be in use for any purpose?

No person shall be engaged in any work activity on or so near any live conductor (other than one suitably covered with insulating material so as to prevent danger) that danger may arise unless-
(a) it is unreasonable in all the circumstances for it to be dead; and
(b) it is reasonable in all the circumstances for him to be at work on or near it while it is live; and
(c) suitable precautions (including where necessary the provision of suitable protective equipment) are taken to prevent injury.
Is that better?
Is that the definition in the EAWR?
If you're at work then the EAWR apply. "Work activity" means anything you do there as part of your job.
From whom does an electrician get a permit to allow him to do testing in a customer's home?

Sounds like a good idea, wait for the 18th edition.
That'll be the edition which also says you can do anything you like so long as you RCD it.

that will make life easier for the DIYer and we can all sign on the dole, after six months if your self employed.
