Because PAT Testers have an IEC socket for testing leads and not a cloverleaf socket, you will require an IEC to cloverleaf convertor.
You simply plug the cloverleaf cable into the 13 Amp socket on the tester. Then you plug the cloverleaf plug of the lead into the female socket on the adapter, finally plugging the IEC plug of the adaptor into the IEC socket on the tester. You then proceed with a standard lead test.
We can supply cloverleaf adaptors from stock.
