It should be noted that any support fixings used to support the cable must not lead to premature collapse of the cable in a fire, regardless of whether the cable itself is fire resistant or not. Clause 521.10.202 in BS7671 refers. We do not provide guidance on the most suitable clips to use for the twin and earth as we do not supply these, but would advise the cable is 5.3mm x 9.9mm in dimension. The clips need to be either steel or copper in construction
