Li-RCD li ka sebelisoa e le karolo ea moralo oa ho kenya ho etsa hore litlhoko tsa ts'ireletso ea liphoso kapa ts'ireletso e eketsehileng e fihlellehe.
- Teko ea impedance ea Earth fault loop e lokela ho etsoa le ho netefatsoa e le e amohelehang pele li-RCD li lekoa.
- Konopo ea teko ho RCD e lokela ho tobetsa ho netefatsa hore RCD e sebetsa pele ho teko.
- BS 7671 ke maemo a tlase mme e laela feela hore li-RCD tsohle li lekoe tlas'a tlhahlobo ea AC ea hajoale.
- Haeba RCD tester e ntseng e sebelisoa e na le litlhophiso tsa mefuta e meng ea li-RCD ho bohlokoa ho etsa liteko tse ka tlase.
- Li-RCD li lokela ho lekoa ka bobeli ba li-cycle tse ntle (0 °) le tse mpe (180 °) tsa phepelo ea AC ka nako e phahameng ka ho fetisisa ea ho khoptjoa.
