Qhov siab no - lub hwj chim qhov hluav taws xob, los ntawm nws lub qhov (socket) qauv mus rau nws cov xaim thiab ntsaws, nruj me ntsis raws li 16-amp (4000-}watt) kev teeb tsa, ua kom txaus siab rau cov kev xav tau ntawm cov khoom siv hluav taws xob siab. Nyob rau tib lub sijhawm, nws siv cov thev naus laus zis tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv, kev tiv thaiv kev tiv thaiv overload nrog lub zog hloov rau cov lus teb zoo heev. Thaum lub load tam sim no tsis pub dhau lub qhov (socket) qhov ntsuas load, tus tiv thaiv overload yuav tsis qhib; thaum lub load tam sim no tshaj lub qhov (socket) qhov ntsuas load, tus tiv thaiv overload yuav ceeb toom thiab txiav tawm lub hwj chim nyob rau hauv ib lub sij hawm. Qhov siab dua qhov load, qhov nrawm dua lub zog txiav tawm.
Tsis tas li ntawd, nws qhov kev tiv thaiv overload muaj nuj nqi yog resettable. Tsuas yog nias lub pob tiv thaiv overload kom rov ua haujlwm li qub. Nws yog reusable thiab yuav tsum tsis muaj fuse hloov, ua kom yooj yim rau siv thiab zoo tiv thaiv cov khoom siv hluav taws xob thiab tsev neeg hluav taws xob kev nyab xeeb.
