Conductor identification - what would you do

jbrameld
You are replacing some old-fasioned light fittings (that look like inverted 1970s pub ashtrays screwed to the ceilings) with shiny new LED dome fittings.  The house is wired in T&E with red and black cores and you find that the switched line feed is coming into the existing fitting as a black core in a T&E.  Mostly you have found that these have been nicely oversleeved in red, but one or two aren't.


Would you :


a: Oversleeve/mark in red to be consistent with the existing wiring

b: Oversleeve/mark in brown as that is the common 'current' colour for a single phase line conductors

c: Leave it as black as that is an allowed 'phase' colour these days......!

d: Something else - if so what?

    Option a is very interesting - clearly you are providing identification that does not comply with the current BS 7671, but at the same time, you are not fitting that wiring, you are in effect returning it to the state it should have been in at the time? Let's say the sleeving fell off when you removed the light fitting, and got lost - would it then have been OK to put red sleeving back?


    Option b is of course compliant with the current version of BS 7671, and would have to go top of the list of options, but it would require the "colours to 2 versions of BS 7671" label of Regulation 514.14.1 to be fitted.


    Option c would not comply. Single phase line conductors all have to be brown now - the option of using the phase colour for single phase circuits was removed when the new colours were introduced, to avoid the confusion that might otherwise ensue.


    Option d - alphanumeric - fit an oversleeve with L on it (e.g. https://uk.rs-online.com/web/p/cable-markers/8121149/). No requirement for "colours to 2 versions of BS 7671" label.
