Crimping of flexible cord conductors

PG
Like most of us, I often crimp flne strand conductors, especially for screw terminals but do not do this for domestic lamp holders and roses etc.

I thought that I would check Section 526 (Electrical Connections) of the Regs but did't find a clear statement of requirements for crimped ends. 

I was particularly unsure of what 526.9.1 was specifying for fine wire conductors "conductor ends shall be suitably treated".


Any guidance or comment would be appreciated.


Regards

    I replaced a consumer unit, the guy who had installed the previous consumer unit had used insulated boot lace ferrules on the 25 mm meter tails inside the 35 mm cage terminals of the main switch.


    I just pulled the ferrules off with my fingers and threw them away, they had not been crimped with a tool and even if they had I don’t think it would have made much difference. 

     


    I seem to recall that Hager supplied a pair of ferrules, for fitting to the main switch, with their consumer units, for a short period of time, in the 1990s.

    Giving 25 mm crimps to someone who doesn’t have a crimper isn’t possibly the best of plans.


    Try Bod on the subject of not crimping crimps and relying on tightening the terminal to do the job.
