Flexible 'tails'

grahamro

I was working on a job the other day where an e.on man was fitting a smart meter.
In converstion he told me that e.on were taking out any flexible tails they found fitted between the cut out, meter and any isolator installed.
From the meter or isolator, the customers 'tails' if flexible would of course be left installed.
Seeing as how I'm trying to save more wear and tear on my digits which are now suffering badly after years of bending 25 & 35mm2 'tails' I'll keep using flexible 'tails' untiil I'm told oficially a reason not to.
Apparently this doesn't apply to various other service providers.

  • I presume the "flexible" ones are 19-strand vs the traditional 7-strand ones.

    While the 19-stand ones are easier to use and most likely fit more reliably into cage-clamp terminals found in most CUs these days, they don't necessarily do as well in the twin screw tunnel terminals (still usual on the DNO/meter side of things)- as the thinner strands are more likely to escape the screws. Ferruling in theory should help, but that in a way makes it a single strand - which the terminals probably haven't been tested for either.

    I don't know what the difference in overall diameter is between the two variants but the 19 strand definitely fills the barrel on a 100A credit meter, there's no way the terminal screws are going to squirrel their way past the strands. As for fitting ferrules, you'll never get one to fit in the barrel both types of cable are a snug fit in a 100A meter.
