Evening all
Just wondering what would be the reference method given for a twin and earth cable in a cavity wall without insulation....I understand with insulation its either 102 or 103 but these massively de rate a cable and so was thinking is it b without the insulation as it acts similar to a void. I'm still learning so just trying to memorize as many scenarios as possible really but look forward to any responses.
