Loadcenters tseem txwv rau 240V lossis tsawg dua thiab feem ntau yog muab ntawm 100 A lossis tsawg dua, nrog qhov ntsuas siab tshaj plaws tam sim no txog li 400 A.
Yog li ntawd, qhov txawv ntawm lub ntsiab breaker vaj huam sib luag thiab lub ntsiab lug vaj huam sib luag yog dab tsi?
Main lug panels tsis muaj ib lub ntsiab breaker . Hloov cov kab hlau khiav mus lug . Cov lub ntsiab breaker , uas yuav ua hauj lwm raws li lub disconnect, tej zaum yuav nyob rau hauv lub 'meter', los yog yog hais tias tus lub ntsiab lug vaj huam sib luag yog siv raws li ib tug sub- vaj huam sib luag , nws tuaj yeem txuas nrog breaker ntawm vaj huam sib luag loj.
Yuav ua li cas hloov lub GE Main lug mus rau lub ntsiab breaker?
Hloov GE Load Center rau lub ntsiab breaker
- Hloov tag nrho vaj huam sib luag = $3600.
- Nruab ib "cov khoom siv hloov pauv hloov pauv loj" rau saum lub thawv thiab "ua qhov chaw" = $ 600. Tam sim no lub zog tuaj rau hauv lub thawv thiab txuas mus rau ob lub lugs. Muaj 3 lub qhov hluav taws xob ob-ncej uas yuav tsum tau muab pov rau lub zog tiag tiag rau tag nrho lub tsev (qhov cub, "lub ntsiab", thiab lub vaj huam sib luag sub).
