Kabati yogawa mphamvu ya XL imatenga zida zatsopano zopangidwira kunyumba. Chigoba chake chimapangidwa ndi zitsulo zopindika, zokhala ndi mawonekedwe ophatikizika, kukonza kosavuta, komanso kuphatikiza kosinthika kwamadongosolo ozungulira. Kuphatikiza pa ma air circuit breakers ndi ma fuse oteteza dera, kabati yogawa imathanso kukhala ndi ma contactors ndi ma relay otenthetsera. Khomo lakutsogolo la bokosi likhoza kukhala ndi mabatani ogwiritsira ntchito ndi magetsi owonetsera. Pamene chosinthira mpeni chikufunika, chogwirira chake chogwirira ntchito chimayikidwa kumtunda kwa gawo lakumanja kutsogolo kwa bokosi, lomwe lingagwiritsidwe ntchito posinthira magetsi. Kabati ili ndi chitseko kutsogolo, ndipo chitseko chikatsegulidwa, zida zonse mkati mwa nduna zimawonekera, zomwe zimathandizira kukonza ndi kukonza. Khomo lakumaso ndi chitseko chotsegulira kumanzere kwa tsamba limodzi, chokhala ndi zida zoyezera monga voltmeters ndi ammeters, komanso kugwiritsa ntchito magetsi ndi zida zamagetsi. Ndi chipangizo chogawa mphamvu chokhala ndi dongosolo losavuta, ntchito yodalirika, komanso mtengo wotsika. Ndizoyenera kugwiritsidwa ntchito m'mafakitale ndi nyumba zachitukuko za AC pafupipafupi 50Hz, voteji 500V ndi pansi pa IT machitidwe, machitidwe a TN-C, machitidwe a TT (omwe poyamba ankadziwika kuti atatu-gawo atatu-waya, magawo atatu amagetsi amagetsi amagetsi anayi) kuti agawire magetsi ndi magetsi. Ndiwoyeneranso kupanga makabati osiyanasiyana oyambira ma mota, kuphatikiza makabati oyambira amagetsi odzaza ndi digito, makabati oyambira owongolera a digito, makabati oyambira osinthira makina, makabati oyambira nyenyezi-delta, makabati oyambira ma mota ambiri, ndi zina zambiri.
Chogulitsachi chikugwirizana ndi mfundo zomwe zikugwiritsidwa ntchito: IEC60439-1 "Low-voltage Switchgear and Controlgear Assemblies" ndi GB/T 7251.12 "Low-voltage Switchgear and Controlgear Assemblies - Gawo 1: Misonkhano Yoyesedwa ndi Mtundu Wapang'ono". Mulingo wachitetezo ndi IP30.
