Testing RCD Protected Extension Leads with Supernova, Europa or Primetest 300

These extension leads will of course fail the Insulation Test.

The Code of Practice says to do a leakage test instead of the insulation test.

The test procedure can be done in two ways either as a manual test or an edited automatic test.

The manual procedure is as described in the Instruction Manual and selecting the test procedure to be done.

Supernova/Europa

1a) Set an automatic procedure where you encounter a lot of these types of connections.
