An existing installation in a hotel is to be inspected and tested as a requirement of the local authority for a public entertainment licence application. Previous inspection and testing records exist but two additional socket-outlet circuits have previously been installed for which there are no test results available.

What action should be taken with regard to the additional socket-outlet circuits?

• Both should be sampled to check compliance with BS 7671.

• One should be sampled to check compliance with BS 7671.

• Both should be fully tested to check compliance with BS 7671.

• One should be fully inspected to check compliance with BS 7671.
