Sample text

2 Ring final circuit supplying socket-outlets (total protective conductor current exceeding 10 mA). DISTRIBUTION BOARD PE separate connections Accessories must have two terminals for protective conductors. One terminal to be used for each protective conductor. Radial circuits Radial circuits supplying sockets where the protective conductor current is expected to exceed 10 mA are required to have a high integrity protective conductor connection. 3. This will provide a duplicate connection for each socket on the circuit.

If there is concern in this respect the location of earth electrodes should be discussed with the electricity distribution company. All circuits supplying socket-outlets (other than any from a SELV supply) are required to be protected by a 30 mA RCD. 5 605-03-01 Earth electrode resistances Where protection against electric shock is provided by an RCD the following condition is required to be fulfilled : 605-06-01 RA I∆n ≤ 25 volts where : RA is the sum of the resistances of the earth electrode and the protective conductor(s) connecting it to the exposed-conductive-parts I∆n is the rated residual operating current of the RCD.

Ii) The connecting flexible cable should be disconnected firstly from the marina socket-outlet and then from the leisure-craft inlet socket. Any cover that may be provided to protect the inlet from weather should be securely replaced. The connecting flexible cable should be coiled up and stored in a dry location where it will not be damaged. * appropriate figures and colours to be inserted. 3.
