Nā Paʻa Uila: NEMA 4 vs.NEMA 4X

No ka hoʻomalu ʻana mai nā pōʻino e like me ka pili kanaka a me ka ʻinoʻino, hoʻokomo pinepine ʻia nā ʻāpana uila a me nā mea pili e like me nā mea haki uila i loko o nā pā.Akā, no ka mea e koi ana kekahi mau kūlana i nā pae kiʻekiʻe o ka palekana ma mua o nā mea ʻē aʻe, ʻaʻole i hana ʻia nā pā āpau.No ka hāʻawi ʻana i ke alakaʻi i nā pae o ka pale a me ke kūkulu ʻana, ua hoʻopuka ka National Electrical Manufacturers Association i kahi hoʻonohonoho o nā alakaʻi i ʻae ʻia ma waena o ka ʻoihana uila e like me ke kūlana de facto no nā paʻa uila.

Ma waena o ka nui o nā helu NEMA, hoʻohana pinepine ʻia ka pā NEMA 4 no ka pale ʻana i nā mea, me ke anuanu a me ka hoʻokumu ʻana o ka hau ma waho o ka pā.Hāʻawi ka NEMA 4 i kahi degere o ka palekana, a ʻo ia ka pā haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa.Eia kekahi, hiki iā ia ke pale aku i ka paʻi ʻana i ka wai a me ka wai hose-directed.Eia nō naʻe, ʻaʻole ia he pahū, no laila ʻaʻole kūpono ia no ka hoʻohana ʻana i nā noi ʻoi aku ka weliweli.

Eia kekahi, ua kūkulu ʻia ka pā NEMA 4X.E like me ka maʻalahi i koho ʻia, ʻo ka NEMA 4X kahi ʻāpana o ka helu NEMA 4, no laila hāʻawi ia i ka pae like o ka pale ʻana i ka wā o waho, ʻoi aku ka lepo, ka ua, ka ua a me ka lepo i puhi ʻia e ka makani.Hāʻawi ia i ka pae like o ka pale ʻana i ka paʻi wai.

ʻO ka ʻokoʻa, ʻo ka NEMA 4X pono e hāʻawi i ka pale hou aku i ka corrosion ma mua o ka mea i hāʻawi ʻia e ka NEMA 4. ʻO ka hopena, ʻo nā pā hale wale nō i hana ʻia mai nā mea pale-corrosion, e like me ke kila kila a me ka alumini, hiki ke kūpono i ka helu NEMA 4X.

E like me ka nui o nā pā NEMA, hiki ke hoʻohui ʻia nā ʻano koho like ʻole, me ka hoʻoulu ʻana i ka ea a me ka mālama ʻana i ke aniau o loko.
