Ang galing nyo po mag explain sir. Daghang salamat

[@pinoyelectrical]

Maraming salamat din

Boss, sa 2-wire system... mas tama po ang Line-to-Ground. Kasi ang grounded conductor ay connected sa earth, kaya ang tawag po sa kanya ay GROUNDED SERVICE CONDUCTOR (GSC), hindi po neutral. Pero, nasanay lng tayo na tawagin neutral kasi return current path siya pag may load na... sa NEC, tawag diyan ay GSC, pero mga electrian ay neutral na tawag... hehehe

2 - wire system, ito ay transformer. Isang linya ang tawag ay ungrounded conductor (line) at ang isang linya ay grounded conductor ( neutral? or ground?). Ano ba definition ng PEC at NEC tungkol ng "GROUND"?

[@pinoyelectrical]

Pwede rin matawag na ganito. Line is not connected to earth. At Alin ang tama dito? *Neutral is intentionally connected to earth. or *Ground is intentionally connected to earth?

[@pinoyelectrical]

Pwede din. 2-wire system Galing service entrance papunta sa service panel maglagay tayo ng service entrance conductors (isang ungrounded conductor at isang grounded conductor) Other term: Alin ang tama? Galing service entrance papunta sa service panel maglagay tayo ng service entrance conductors (isang line conductor at isang neutral conductor) Or Galing service entrance papunta sa service panel maglagay tayo ng service entrance conductors (isang line conductor at isang ground conductor)

[@pinoyelectrical]

Meron pa. 2-wire system From panelboard to convenience outlet: 1 ungrounded conductor 1 grounded conductor 1 equipment grounding conductor. Other term : Alin ang tama 1 line wire 1 neutral wire 1 grounding wire Or 1 line wire 1 ground wire 1 grounding wire

[@pinoyelectrical]

So Alin ang Mas consistent sa 2-wire system , from distribution transformer to outlet " LINE TO NEUTRAL" or "LINE TO GROUND" Para sa akin nasa video ang sagot with supporting document.

tanong ko lang po sir bakit po nag spark yung neutral line sa 3phase pag dinikit po ground?

[@pinoyelectrical]

Sa Transformer o switchgear ay bonded ang ang neutral at ground conductor. Pagdating na sa mga panels wala ng bonding between neutral at ground wire. Ang neutral ay may current at kun didikit sa ground wire magspark kasi dadaan din current sa ground wire at yan ay tinawag na objectionable current at yan ang kilangan iwasan. Pero gumamit tayo ng AFCI, GFCI, RCD, RCBO- magtrip itong mga devices kapag makadikit ang neutral sa ground wire. Kasi madetect nila agad ang imbalanced current.
