Re: House electrical rewiring/rerouting, etc.

konting update:

katatapos lang ang tile job sa aming tahanan. pintura na lang then electricals na.

may nakuha na akong electrical engr. sya kasi ang gumawa ng electricals ng ginagawang bahay ng isang kamag-anak at ang sabi ay PhP 100.00 per outlet ang singil nya. tama lang ba yung rate?

nagawan ko na rin ng simpleng sketch ang floor plan ng bahay tsaka listahan ng mga present and future loads with their respective power ratings, current draw, etc. ibibigay ko na lang sa engineer along with the provisions of a power transfer switch for generator, all-around convenience outlet sa bawat room along with the standard outlet (para maisaksak ang mga appliances/gadget na iba ang prongs), etc.

may naitabi na rin na budget for the design and drawing expenses. hiwalay pa daw ang gastos sa draftsman. after that ipon uli for the materials and labor ng electrician. good thing may kakilala at kapitbahay kami na electrician/line man ng electric coop dito samin. lisensyado naman daw ayon sa tito ko.

mukhang pass muna ako sa tool shopping. hehehe

sa mga may shop dito, ilan amperes po ba rated ang mga meters ninyo?

salamat

Re: House electrical rewiring/rerouting, etc.

mga kaibigan, may tanong ako regarding ground fault circuit interrupters (GFCI).

paano ba malalaman kung yung circuit o yung outlet mismo e gfci? eto ba yung 3 prong outlets or something else? i assume hindi gfci yung mga regular/ordinary 2 prong outlets sa karamihan ng bahay.

GFCI equipped ba yung mga bahay nyo or shop nyo mga sirs?

practical pa ba ito na ilagay sa electrical system ng bahay dito sa pinas?

salamat sa sasagot.

[COLOR="Green"]Yes bro miked, that's about the rate of an electrician though there are others who would charge a bit higher kung alam nila na medyo mapera ang nag papagawa ng bahay.

sa mga may shop dito, ilan amperes po ba rated ang mga meters ninyo?

[COLOR="green"]My main electric post has a 100 ampere circuit breaker and then the main house has the same 100 ampere circuit breaker with several breakers for each room, sala, kitchen, and outside lights.
For my welding machines, my supply is 60 amperes and garage outlets are 30 amperes.

[COLOR="green"]Bro miked, ang may grounding lang sa amin ay yung main electric post, here in my house we don't use electrical outlets with 3 prongs since almost all the appliances we use are
for the regular 2 prongs.
I don't think its necessary unless most if not all your appliances are imported from the USA.

Hope this helps ! 😉

Re: House electrical rewiring/rerouting, etc.

salamat ka rosy sa info....100 amperes nga ang aking napansin sa karamihan ng bahay..

i'm planning a dedicated outlet for welding at isang duplex outlet for other power tools sa aking munting garahe. pero depende pa rin sa usapan namin with the engr. yung meter namin (fuji dharma) is rated at 10 (30A)...yung sangamo eletric na luma (kina erpats) ay ganun din...anyway ifinalize na lang yung details with the engr.

Re: House electrical rewiring/rerouting, etc.

Tanong ladies and gentlemen:

2-wire 230 volts ang aming electrical service dito sa aming bayan. tapos may sariling grounding rod ang aming bahay at meron din sa may poste sa tapat namin kung san galing ang aming service entrance. bale isang insulated (black) wire at isang bare aluminum wires ang aming service entrance.

ngayon ang tanong ko po ay kung anung klaseng service ito: line-to-ground o line-to-line system po ba ito?

kaya ko po ito naitanong mga kaibigan dahil sa kung anung klaseng circuit breaker ang ipapalagay ko sa electrician pagdating ng araw kung single- or double pole ba.

kung line to ground kasi ay single pole breaker lang. hindi na kelangan lagyan ng fuse/breaker sa return.

kung line-to-line service naman ay kelangan ng fuse/breaker sa "hot"/supply at sa return line (bale double pole circuit breaker bale ang gagamitin).

nakakalito na kasi yung conventional fuse kina erpats e may fuse ang return habang etong samin sa ngayon e single pole circuit breaker (bale walang fuse/breaker sa return).

isa pa e, yung bahay ng kamaganak namin e double pole circuit breakers ang nasa panel nila e parehas lang kami ng electrical service galing sa electric coop.

hindi na pala ako kukuha ng electrical engr dahil lower than 60 amperes ang lumalabas sa computation ko para sa aming bahay. wala pang derating yun dahil hindi naman sabay sabay lahat. yung welding machine at grinders ko lang naman siguro ang magsasabay. andito naman sa tabi ko mga notes at libro sa electrification class ko nung araw plus yung libro ni fajardo.

Re: House electrical rewiring/rerouting, etc.

ngayon ang tanong ko po ay kung anung klaseng service ito: line-to-ground o line-to-line system po ba ito?

Kailangan nyo po ng volt-meter para malaman ang kasagutan.

Sukatin ang boltahe sa pagitan ng isang linya at ground. Kapag ang lumabas ay 230V (o malapit dito), ang serbisyo sa inyo ay line-to-ground. Dito sa aming nayon ang nasusukat ko ay 110V. Ibig sabihin ang serbisyo sa amin ay line-to-line.

Para akin mainam ang ganitong kompigurasyon. Maari ko kasing gamitin ang line at ground para paandarin ang aking mga kagamitan na 110V. Yung mga mababang amperahe lamang.

Re: House electrical rewiring/rerouting, etc.

i therefore conclude na line-to-ground yung amin....nakausap ko lang din lately yung pinsan kong EE na nasa abroad.

at sabi rin nya na di na kelangan lagyan pa ng fuse/breaker disconnect sa may return side. ganoon din ang sinasabi ng PEC or NEC....

salamats.

Re: House electrical rewiring/rerouting, etc.

mukhang mahirap maghanap ng single pole circuit breaker na 60 amperes and up ah....halos double pole ang available.

Re: House electrical rewiring/rerouting, etc.

yan ang problem sir, mahirap maghanap ng single lang. but i would suggest to use double pole notwithstanding na return or ground line yung isang service entrance nyo unless naka perfect grounding ang electrical installation sa load side. a cent from a former alaktrical gingineer

Re: House electrical rewiring/rerouting, etc.

nasa bill of materials na rin yung sarili naming grounding rod. worst case scenario e single pole yung branch circuits tapos double pole yung main disconnect....acceptable pa kaya iyon gingineer phezthie? hehehe...

kaso yung kamag-anak namin na malapit na matapos bahay e double pole CBs ang ginamit e parehas lang naman kaming 2 wire line to ground 230 volts service.

hmmmmm.....

Re: House electrical rewiring/rerouting, etc.

I will not advise that sir miked...

Actually, your concerns emanated from that line to ground power source, consequently, you are trying to adopt your electrical installation based on that set-up. If i were you, i will simply disregard that and just presume that the source is that of a regular distribution, that is, single phase 3-wire or (110-G-110).

You may ask why...

my point is, your power distribution setup is quite outdated. line-ground setting is very common in the past specially for power cooperatives. It was the choice then since as mere cooperative with limited resources, they tried to minimize the expense by using 1 copper wire(plus the aluminum one which is less expensive) instead of 2 copper wires, and simply utilize earth, or ground in layman's term, as another conductor to complete the loop. However, that setup turned out to be impractical because of the huge power or system loss the reason why those with extra resources rehabilitated and upgraded their distribution lines to 2-wire.

Now, the question is, what if your power company decided to upgrade theirs?

you are now in a big dilemma hehehe Besides what you are planning will just save you a little and for me, its not worth it.

BTW, dont rely on that rod (usually about 2-meter length) to make your ground a perfect one. it is just an added safeguard in case the alum wire of that service entrance fails. on some occasions, it is the cause of electrocution specially if you are using metal pipes for water distribution inside the house.

Re: House electrical rewiring/rerouting, etc.

so we therefore conclude na gumamit na lang ako ng double pole CBs? diko rin masabi kung maguupgrade or hindi ang aming elec. coop dito samin. basta 2-wire yung nakikita ko sa mga poste samin na may mga grounding rods at some intervals. atsaka naglalaro ang boltahe magmula 215 v (sa hapon) at 230 volts (sa gabi). 3 araw ko lang na minonitor na ganito ha.

btw, may electrician akong gagawa with my help. kelangan ko lang mafinalize mga plano ko para magkaintindihan kami ng electrician. di nako kukuha ng licensed EE dahil sa katunayan, small family dwelling lang sa amin at mayron naman nang sample yung book ni fajardo. ang nadagdag lang e yung power tools sa "other loads". ang pinakamatakaw so far e yung chopsaw tapos air compressor. malamang inverter welder, grinder at elec fan lang siguro magkakasabay.

salamat ng marami mr. phezthie!

update ko na lang tong thread once matapos na ang project na ito.

Re: House electrical rewiring/rerouting, etc.

Nakabili nako ng circuit breakers (GE TQC), panel (10+1), Panasonic switches & receptacles, Duraflex 3.5 sq. mm. stranded wires and 2 meiji gfci amounting to P20k....half of the project cost pa kelangan para matapos.

kaso mayroon akong hindi masyado nacheck nung nasa tindahan pa ako ni new circulated sa binondo. yung mga sinalpak na CB sa branches ay tig-2 single-pole unit. yung nakaprint sa CB ay 1-pole unit. tapos yung main may nakatatak na 2-pole unit. ok lang ba gumamit ng dalawang single-pole units para maging 2-pole unit?

afaik, yung 2-pole unit ay hindi pwedeng gamitin bilang single pole (kapag tinanggal yung common trip)....hindi ko lang sure yung kabaligtaran, i.e. dalawang 1-pole unit para maging 2-pole unit.

salamat sa kung sino mang makakasagot.

Re: House electrical rewiring/rerouting, etc.

you may want to consider this to future proof your house at no added cost when rewiring your electrical lines ... use a different wire color (red, black, brown) for your electrical wires and clearly instruct your electrician to only connect wires of the same color when installing it ... the result is you'll have 2 or 3 (with ground) close network for IoT (internet of things) and home automation builtin into your home using PLC (power line communication) ... PLC is the oldest (reliable and stable), secure (close network, hard to hack :-)), and most important is cheapest LAN network that you can setup at home because your network is riding on your electrical wires ... no additional cost to your project, just use different wire colors ... cheers
