How do I PAT test a fridge?

Larger equipment such as fridges can have longer leads, and in some cases a longer earth path as part of their construction, and a PAT tester can initially indicate a fail when carrying out the earth continuity test. The test engineer should calculate the expected value using 0.1+R calculation, where R is the resistive value of the cable, depending on it's length and cross-section. IET code of practice has a table of these values.
