Waa maxay cabbirka siliga 30 amps 300 cagood?

Isticmaalka fiilada korantada ee cabbirka saxda ah ee wareegyada ayaa muhiim u ah ka hortagga khataraha iyo ka hortagga dabka. Tani waxay sabab u tahay xaqiiqda ah in marka korantada lagu kala qaado masaafo dheer iyada oo loo marayo fiilooyinka naxaasta ama aluminiumka, hoos u dhaca danabka ayaa dhici kara. Sidaa darteed, si loo hubiyo badbaadada, waa inaad isticmaashaa siliga saxda ah ee silsiladdaada 300 cagood.

Sug inta aan ku tusi doono xisaabaadka qaarkood oo aan ku baro cabbirrada fiilooyinka aad u isticmaali karto rakibaadda mustaqbalka:

Intee in le'eg ayaad u baahan tahay 30 amps? (80% koodhka NEC)

Waa inaad isticmaashaa silig xamili kara ugu yaraan 37.5 amps. Markaa # 8 silig AWG oo xamili kara 50 amps ayaa ah siliga ugu habboon ee siligan laanta.

Caadi ahaan waxaan isticmaalaa xisaabiyaha hoos u dhaca danab ama shuruudaha Xeerka Korontada Qaranka (NEC) ee cabbirka siliga 30 amp ee la aqbali karo.

** Xawaaraha 30-amp, si fudud uma isticmaali kartid 30A silig koronto.

Xataa uma baahnid inaad isticmaasho silig #10 AWG 35A. Tani waa sababta oo ah culeyska ugu badan ee silig kasta oo wareeg ah waa 80% qiimeynta wareegga hadda ee culeys kasta. (NEC 220-2)

Faa'iidooyinku waxay ugu yeeraan xisaabiyaha hoos u dhaca danab ee NEC oo leh 80% cabbir koronto. Tani waxay tusinaysaa in 30-kan amps ay ka dhigan yihiin in aan ka badnayn 80% culayska la qiimeeyay ee siliga (silig naxaas ah ama aluminium).

Waa kuwan sida loo go'aamiyo inta xadhig ee awoodda aad u baahan tahay 30 amp oo korantada ah:

Iyadoo la tixgelinayo shuruudaha 80% ee NEC, waxaan aaminsanahay in 35A #10 AWG aysan ku filneyn. Waxay ku dhowdahay inay ku weyn tahay 35A, laakiin maahan mid aad u weyn.

Waxaan u baahanahay fiilo xamili kara ugu yaraan 37.5 amps si aan u isticmaalno furaha 30 amp. Cabbirka soo socda siliga #10 AWG (35A) waa cabbirka siliga #8 AWG (50A).

Sidaa darteed, cabbirka siliga ugu habboon ee 30 amp circuit jabiyaha waa # 8 AWG, kaas oo leh qiimeynta hadda ee 50 amps.

Waa maxay cabbirka siliga 30ft 300 amp panel-hoosaad?

Waxaad u baahan doontaa silig xamili kara ugu yaraan 60 amps.

Markaa adeegsiga siliga #6 AWG ee xamili kara 65A ayaa adiga kuugu fiican.

Waxaan ku bari doonaa sida aan u xisaabiyay hoos.

Hoos u dhaca danabku wuxuu yimaadaa marka korontadu lagu kala qaado silig naxaas ah oo 30 amp ah ama 30 amp silig aluminium fogaan ah. Hoos u dhaca korantada waxaa lagu hayaa in ka yar 3% in ka yar 10 cagood, markaa uma baahnid inaad tixgeliso. (1)

Tusaale ahaan, waxaad u baahan tahay inaad ku xisaabtanto hoos u dhaca danabyada 50, 100, 200, ama 300 cagood. Intaa waxaa dheer, waxaad la qabsaneysaa tan adigoo kordhinaya xoogga hadda jira. Laakiin intee?

Marka loo eego NEC 310-16, hadda waa in lagu kordhiyaa 20% 100 cagood kasta laga bilaabo 30 amp panel.

Si fudud loo dhigo, tani waxay ka dhigan tahay inaad:

• Ku kordhi hadda 10% ee 30 amp silig oo 50 cagood u jirta guddida qalabaynta.
• Kordhi amperage 20% ee 30 fiilooyinka cabirka amp 100 cagood u jira guddi hoosaadka.
• Ku kordhi hadda 40% ee 30 amp silig oo 200 cagood u jirta guddida qalabaynta.
• Ugu dambayntii, ku kordhi amperage 60% ee 30 amp silig 300 cagood ka soo gole dheeri ah.

Kuwa soo socda ayaa muujinaya sida loo go'aamiyo awoodda 30 amps meel fog:

Aynu nidhaahno waxaad u baahan tahay guddi-hoosaad 300 cagood u jira 30 amps dhexe.

Waxaan horey u ognahay in ugu yaraan 0 amps ee hadda looga baahan yahay 37.5 cagood. Si loo qeexo 300 cagood oo dheeraad ah oo ka mid ah guddiga qalabka, waa inaad ku kordhisaa hadda 20% 100 cagood oo kasta oo fogaan ah. Markaa waa inaad ku kordhisaa amperage 60% si aad u hesho ku filan 300 cagood ee wareeggaaga.

Sidaa darteed, waxaad u baahan tahay xariiq awood u leh inuu qaado ugu yaraan 60 amps oo ah wareegga 30 amp ee 300 cagood. Nasiib darro, #8 silig AWG hadda waa 50A oo keliya.

Xaaladdan oo kale, dooro #6 AWG silig leh 65A.

• Waa maxay cabbirka siligga 30 amps 200 cagood
• Silig intee le'eg ayaa loogu talagalay 150 amps?
• Halkee laga heli karaa silig naxaas ah oo qaro weyn oo qashinka ah
