Ukutholwa kwephutha
Iningi lemindeni yase-UK liyaphindwa ngohlelo lwe-PME (ukuvikela umhlaba omningi), lapho umhlaba we-wiring ugijimela khona endaweni ekhokhelwa imali exhunywe kumqhubi we-netral ophathwayo emaphoyilini amaningi. Lezi zinhlelo zinamandla okuthola iphutha elingajwayelekile elibizwa ngokuthi ukwehluleka okungathathi hlangothi, lapho ukuxhumeka komfula ngenxa yokonakalisa noma ukugqwala kungakhulisa ubungozi bokushaqeka kukagesi.
Ukutholwa kwe-Pene iphutha: Ngezinhlelo ze-TN-CS ngaphandle kokuphela kokuphela komsebenzisi (njengoba kukhonjisiwe ngenhla), lapho umugqa wepeni uye emndenini unqunywe ngenxa ye-pen line , futhi ibhokisi lokusabalalisa i-RCD alisebenzi kahle ngalesi sikhathi, ivolumu ye-Ground Ground PE ilingana namandla kagesi omlilo we-L.
Uma kungahlomiswa ngalokhu kuvikelwa, igobolondo le-EV ekushajayo lizokhokhiswa ngama-voltage alingana nomugqa womlilo l
voltage. Uma kungekho ezinye izinto zokwakha ngaphandle kweshaja ye-EV, okuvuza kwamanje kuzodlula i-30mma futhi umuntu ngeke akwazi ukuzikhipha, okuyingozi yokuphepha; Uma kukhona neminye imisebenzi, i-evuza yamanje ingadlula kalula i-100mA, okubulalayo kakhulu.
