Why is the 120 VAC 60 cycle used in Manila?
It seems likely that the American-style 120 / 240 VAC 60 cycle used in Manila may have been the result of the fact that electrical systems in Philippine cities were expanded during the American occupation of the Philippines between 1899 and WWII.
How is the Philippine system similar to the U.S.?
From the standpoint of electrical engineering theory , the Philippine system is similar to that used in the U.S. and Europe. From the utility pole to the residence panel box we have one or two load wires and neutral conductor. We have a ground (earth) provided by the homeowner. You can explore the technical details at http://en.wikipedia.org/wiki/Earthing_system and various other sites. However there are some big differences in materials and techniques between the USA, Europe, the U.K. and the Philippines. Looking at how things were done when we built our Philippine house may help other considering house building in the Philippines to get an idea how things are done here. One final note. The Philippine electricians we have met have been quite professional. It’s best to hire an electrical engineer to do your plan (you will need it for your building permit), and have good electricians to do the work. Wage rates are negotiable and far more reasonable than in your home country. We hope this essay will be of help in making you a more knowledgeable home builder.
What is duplex cable?
The meter-to-house wire is referred to as “duplex cable”. If it was three wire it would be referred to as “triplex”. Our duplex feed cable is a #6 AWG load wire which is insulated and wound with an un-insulated neutral wire. Both are aluminum. We had to pay for the duplex wire extending from the meter to our house. We paid about P17 per meter for this cable at Western Lamp, an electrical supply house in Iloilo City. The utility may provide the wire and/or the meter and bill you for it monthly until it’s paid for. You’ll pay more this way.
Where are the black and green wires on a utility pole?
The black and green feed wires on the left go into our attic and through conduit to our panel box. Again, from the fact that there is only one load wire, we can guess that we have a two wire 230 v. system. If you had seen two black wires and a neutral leading from the pole to the house, you’re probably dealing with a three wire 120/240V system.

Do you need neutral wire for a switch?
There are a few hardwired automated switches that don't need a neutral wire, but these are in the minority. Also, you'll be limited to incandescent lights. DigitalHome is one of the few companies that have the solution to your problem.
Why Are There Different Types of Neutral Wire Color?
These colors have to be different because the wires need to be composed according to the amount of voltage they'll be used for.
Why are AC wires different colors?
These colors have to be different because the wires need to be composed according to the amount of voltage they'll be used for. It's important to be able to identify and correctly use ...
Why are neutral wires important?
Neutral wires have the important task of returning currents to the original power source; this is a necessary function of AC power, and we need to be able to identify these wires properly and make sure we use them for the right voltage connections. Electricity is so omnipresent we often don't think about how it works.
Why do neutral wires carry currents?
Neutral wires carry currents back to power source to better control and regulate voltage. Its overall purpose is to serve as a path to return energy. Ground wires are electrical paths designed to carry fault currents when a power abnormality occurs. They don't carry currents-their purpose is to provide operator safety.
What is AC power?
AC power comes in a variety types based upon the number of volts the wires will be carrying. This voltage is often found in homes and businesses that don't require a lot of energy.
What is the difference between AC and DC power?
Neutral wires only exist in AC power; DC power consists of a positive, a negative, and a ground. AC power, on the other hand, have "hot" wires (which come in three phases), a neutral, and a ground. It's the neutral wire that allows for the current to alternate, since the neutral wire acts as the roadway back to power source.
How to stay up to code and accident free electrically speaking?
The best way to stay up to code and accident free electrically speaking is to adhere to wire color codes. But first, it's best to understand exactly what a neutral wire is, why it's important, and how to identify a neutral wire by color.
What is the neutral wire for?
In AC power systems neutral wires are there to provide a low-impedance path that goes either to the earth, or to another grounding location. This will help to prevent high voltages from passing into the system, which could cause damage, fires, or other issues.
Standard Neutral Wire Color
In both the United States and Canada neutral wires should only be white or grey. This is because the standards put forth by both the US National Electric Code and the Canadian Electric Code match up. Many companies have facilities in both of these countries, so it makes sense to ensure the wire color codes are the same whenever possible.
How to make electrical systems safe from high voltages?
Ground was the answer. By bonding (connecting) all the ground wires together, and then bonding the neutral to the ground in the fuse box or service panel, and then connecting ground to the earth, we send any hazardous voltages into the earth instead of through a person who inadvertently comes in contact with the problematic voltage - through a metal appliance, for example.
What is the difference between black and white wire?
In the US, the bare copper wire is safety ground. The white wire is return or neutral . The black wire or dark colored wire is hot. It’s easy to remember. The black wire is the “widow maker”.
What is neutral voltage?
Well Neutral is considered 0 voltage this is the RETURN line to the power company.
What should the wire be when the circuit is on?
If you measure from Ground to any wire, the wire should be ZERO when the circuit is ON. That is usually GREEN or bare Copper to White or (Blue (lately that is being used))
How often does the NEC change?
If you are licensed you then follow the NEC which changes every 2 years and you would then know what each color represents for THAT 2 year period. So in a panel installed in 1975 that is still in service the colors probably are NOT what is used in 2020, thus the Electrician knows where to find the install date to find out what NEC standard was followed and typically uses that same NEC standard for constancy.
What is the nuetral code in the UK?
depends what code you are working too in uk nuetral is blue, line is brown, ground is yellow/green. white for neutral in the us
What is hot wire?
Hot carries current from the circuit breaker or fuse to the outlet. Single pole switches to turn outlets on or off must be installed on the hot wire.
What color wires are used for neutral?

What is a neutral wire?
In an electrical circuit, a neutral wire delivers the remaining power that was left after your smart switch or any kind of appliance draws current, back to the transformer outside your house. It is a path created to facilitate that residual current goes easily back to the energy company.
Why do smart switches need a neutral wire?
Smart switches, dimmers, and so on, require a neutral wire installation so they can be energized all the time.
What is the extra neutral wire on a smart switch?
This extra neutral wire is connected to the Neutral bus and it will have constant current flowing through it. You don’t have it and you need to install it whether it’s you or a good electrician that actually knows what he’s doing.
How to find electrical wires?
Inside a common wall box, you easily find most of the time three cables: 1 Hot wire: Commonly coded with red color at least in the U.S. Basically is the first path that the electricity takes from the transformer outside your house until any kind of electrical device connected to the circuit. 2 Neutral wire: Once any type of your household appliances draws current from the electricity company A.K.A the transformer outside, there is a residual current that needs to go back! And this wire is guilty of it 3 Ground wire: In case something terrible happen with your switch, fridge, or any device, the Ground wire will redirect that current directly to the source, avoiding an accident. If you’re lucky enough you won’t use this cable never in your life.
Why do you need to connect a smart switch to a neutral wire?
Because the current takes the easiest path always and it will go back to the transformer. So, if you want to connect your smart switch to your neutral wire, sadly you’re going to need to install a third wire that is fed with electricity.
Why is the neutral bus oscillating?
Keep in mind that the bus you are looking for is the one that is sending electricity back to the transformer! It should be oscillating because it depends on how much current is being drawn from your connected devices. It will vary, but if it’s showing you information, that’s your neutral bus.
