new equipment existing cabling

[GARS]

hi

we are installing new parking barriers on existing colored SWA (RED YELLOW BLUE). Which should be sleeved (RED GREEN/YELLOW BLACK)?

Do we sleeve the cores to the new colors (BROWN GREEN/YELLOW BLUE) or leave them as the old colors. As they will be the old colors in the DB?

if we have to adjust the length of the existing SWA and re gland do we re-sleeve the colors RED GREEN/YELLOW BLACK? or (brown green/yellow blue)

GARS

If you dont have to extend the cable then to stop any chance of uncertainty I would most like not sleeve an existing RED/YELLOW/BLUE in the new harmonised colours, as you just replacing an existing barrier with a newer one.

The normal sleeving for this would be RED/LIVE no sleeve, YELLOW/sleeved YELLOW/GREEN and BLUE/BLACK

If though you are extending a cable then the new cable should be done in the new colours, and at the origin of the installation a label should be fixed to identify that the installation is wired to 2 different colours of the BS 7671 ( reg 514.14.1)
