Earth continuity test limit

WebOct 31, 2024 · If the test voltage is 3000, then the test current would be 3000/250 x 0.5 or 6 mA. 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 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.
