WebAug 27, 2024 · Re: Earth continuity testing on long runs. Thinking is good. Too many people don't. When doing a loop test, unless the total is below the limit in Table 8.2 it's not technically possible for a single result to "prove" that the PEC is OK. Can't just assume a proportional split, eg 50/50 for PEC size = N size, or other split where PEC size smaller. WebThe limit stated in the Code of Practice for insulation resistance for Class I equipment when tested at 500V d.c. is 1 megohm.

If the test is dc, then the current during the test is a function of the insulation resistance of the system, including the insulation resistance of the stray capacitance and the Y capacitors. The dc current is typically in the tens of microamps. Conclusions
WebEarth Continuity Test. This test is carried out on all Class I appliances during PAT Testing. The purpose of the test is to check that there is a good connection between the Earth pin on the plug and the case of the appliance. A good connection is defined as having a resistance of less than 0.1 ohms (or 100 milli-ohms). Insulation Resistance Test
