3Prevention of accidental electrical contact between customer cable terminations and LV power terminations

3  Prevention of accidental electrical contact between customer cable terminations and LV power terminations   The conductors and terminations of telecommunications cables are not separated from the uninsulated and single insulated conductors and terminations of LV power cables by the minimum distance of 150 mm or by a permanent rigidly-fixed barrier of durable insulating material or metal because the conductors and terminations of the telecommunications cables and LV power cables are installed as follows:  (a) the telecommunications cables and the LV power cables are terminated on building control or monitoring equipment that is installed in a restricted access location where only persons who are qualified and authorised to install or maintain both LV electrical installations and telecommunications installations can gain access; and  (b) separate cables are used for the LV power and the telecommunications services; and  (c) the telecommunications circuits that terminate on the building control or monitoring equipment:  (i) do not share the same cable sheath as any other telecommunications services; and  (ii) only connect to the telecommunications network via a compliant isolating interface.
