Earth Leakage

[ians]

A common problem with random tripping, surge protection plug tops, they break down under load and cause random tripping.

Another common problem, cut insulation on surfix, I have found insulation cut where the electrician strips the cable and doesn't use tape, it gets moisture in the cut and cause nuisance tripping.

In fact there are so many, a good electrician will identify the problem and repair it and others will find other means to overcome the problem, bypassing a stove is one of the common remedies.

This house had various areas from where there were earth leakages. Some where electronic equipment, slight leakage at geysers and borehole pumps and various flourescent lights. Too many to mention here. Eventually it exceeded the 21 milliamps the earth leakage worked at or perhaps the unit had become more sensitive over time, and the only alternative was to raise the threshold of the earth leakage unit.

It is incorrect to remove a stove from the earth leakage protected circuit unless it is connected via a "stove coupler"
See 6.16.3.3 Stove connection.
