oh well, this may not be new for some but for those who still doesnt know these items why dont you try installing them to your house;
- security lights with motion sensor - instead of having an incandescent bulb on the corner of the house which are 'on' the whole night why not try replacing them with this one.as a deterrent as well .saves power though.
- motion sensors - most applicable on closed garage.less hassle looking for the switch.commonly used in offices ;D
- garden lights powered by solar cells - for garden lovers, you may want to light up your garden without paying or adding up your electric bill
- Recessed lights w/ built in emergency ballast - get rid of those wall mounted emergency lights.
- surge suppressors (TVSS) - you may want to install this to your main feeder to protect your appliances from burning from the sudden surge of power.
- GFI breaker/GFI receptacles- a must for every bathroom receptacles or for receptacles outside the house.This might save you from death by electrocution ;D
- timer switch - turning on/off of your pool lights, perimeter lights etc etc, this thing is good on it

Re: technology you should consider

you know where to buy them? motion sensor switch i like that. our motion sensor lights just died though light still functioning yung motion sensor ang sira.

Re: technology you should consider

I'm really interested in GFI breakers. Know where I can buy them?

i am not sure though if they are locally available, but you might want to try visiting ace hardwares, home depot, avesco or federal hardware.we sell them but our store is located oversea.the price range for the sensors are from $30~$50.while for the 2light sensors is $140 and for the single is $107.just giving you an overview.

i love this gfci's, try home depot, ace hardware or avesco.
just to give you an idea of the prices, we are selling the 15A for $21.60 and for the 20A is $23.50 while for the GFI breaker 15A is $55.Take note, selling price namin yan he he he, syemps may patong na pero i'm sure mura dyan. ;D

Re: technology you should consider

GFI breakers are not available at Ace or the other hardwares. I'll ask people to try Avesco or the big electrical shop along Katipunan.

Re: technology you should consider

In regular hardwares, and even the local Pinoy Ace, True Value, you might not find these things. Thing is, these GFI's are used in the U.S. wiring layout is a 115-125 VAC with a true (third) grounding wire. GFI I think means 'Ground Fault Interrupt.'

If most if not all Pinoy homes don't have a true ground third wire, then there won't be any ground fault to interrupt !! Did I get that right?

Perhaps you ought to look at 220 VAC E.U. spec'd GFIs that is, if they call it that. Avesco could probably best help you.

Re: technology you should consider

A GFI senses if the voltage going into a circuit is the voltage going out. If voltage is leaking out, like a person getting electrocuted in the shower, the breaker will trip. I also thought that a GFI, or Ground Fault Interrupter, was meant to tell you if there is a fault in the ground.

Re: technology you should consider

any house which uses emt pipes on their electrical system are grounded.so you can use the gfi, you just have to connect the ground wire to the emt box.

Re: technology you should consider

Ahhh, good to be corrected on this GFI issue, looks like were all right and wrong, so I googled it:

-------

Ground Fault Interrupter

Ground fault interrupters are designed to protect from electrical shock by interrupting a household circuit when there is a difference in the currents in the "hot" and neutral wires. Such a difference indicates that an abnormal diversion of current from the "hot" wire is occuring. Such a current might be flowing in the ground wire, such as a leakage current from a motor or from capacitors. More importantly, that current diversion may be occuring because a person has come into contact with the "hot" wire and is being shocked. When a circuit is functioning normally, all the return current from an appliance flows through the neutral wire, so the presence of a difference between "hot" and neutral currents represents a malfunction which in some circumstances could produce a dangerous or even lethal shock hazard.

GFI's are required by the electrical code for receptacles in bathrooms, some kitchen receptacles, some outside receptacles, and receptacles near swimming pools. The horror story scenarios which led to these code requirements are things like dropping a hair dryer or a portable radio into a bathtub with a person, causing electrocution. A typical circuit breaker interrupts the circuit at 20 amperes, but it takes only about 100 milliamperes to electrocute a person in such a scenario. The GFI is designed to detect currents of a few milliamperes and trip a breaker at the receptacle or at the breaker panel to remove the shock hazard.

The GFI has a "Test" button which causes a small difference between "hot" and neutral currents to test the device. In an example given by John de Armond, the test button put the 120 volt supply across a 14.75 K resistor, producing a current of 8.2 mA. The UL requirement for a GFI is that it trip when there is 5 mA of leakage current. There is also a reset button to use after it has been tripped.

------

My next question to the electricity gurus in this list. Do we have a 'neutral' line in our typical house wiring ? In the U.S. their wires are labeled Hot, Neutral and Ground.

Does this mean that if we do not have a neutral line, then will these GFI's still work? Take note that in the article, the GFi senses the differences between the currents (not voltage) of the hot and neutral lines...

🙂

Re: technology you should consider

I was mistaken in saying that the GFI senses differences in voltage. Indeed, voltage between two wires should be the same. It is the current that will be different if part of the current is being diverted elsewhere.

Regrettably, the 110 volt GFIs in the US may not work in the Philippines. There are, however, some appliances that have GFIs built in, among them water heaters.

As explained in another thread, in Metro Manila, with 110-0-110 volt service, the neutral wire (the 0 volt wire) is also grounded so they are often used interchangeably.

there are two electrical system in the philippines (please correct me if i'm wrong), single phase (households)& 3phase system (industrial).the common household system is the line to line (both wires are hot) and the line to ground (one hot and 1 neutral) usually used in rural areas.i'm not sure though but some say they already used a 220v gfi receptacles.

Re: technology you should consider

Here in Baguio, we have the 220-0 volt system with one line hot and the other neutral. The 110-0-110 system used in Metro Manila is still 220 volts and 2 phase, but there is the added convenience of having a 110 volt line, if desired.

i dont think there is a 2 phase system, it's usually single phase or the three phase wherein you can have the 110v. ;D

Re: technology you should consider

Vtec is right. There is no such thing as a 2 phase. What I meant was single phase for the Meralco 110-0-110 system for residential installations. Even if you connect 3 wires to that system you will never get three phase, always single phase with only the voltage differing.
