Earth Sleeving for 10mm T+E?

jkn · 2018-05-10T09:41:08+00:00

Hi all as per the subject - I am (re)making the connections to an isolator swit ch for an electric shower. The cable is 10mm and due to the construction of the switch I have to twist incoming and outgoing earths together. I can't seem to find 10mm Green/Yellow Earth sleeving online, 6mm seems the largest . Am I forced to use tape (ugh), or is there a source for the sleeving, or a different approach, that I need appraising of? Thanks J^n
