What are electrical wiring codes in the Philippines?
As with any electrical codes throughout the world it is a document for the safe installation and handling of electrical wiring. The set of instruction on how to install equipment is different in many parts of the world due to the different voltages and climatic conditions in which the wiring is installed. The top concern of any code rule is for the safety of the people who use electricity.
Can 110 electrical charge kill you?
1st Answer by ID1041279033
THE CORRECT ANSWER IS the 2nd answer.
Of course! Only 150 volts can kill you, and high voltage is over 1000 volts. Very few dies of so little, but it have happened with only 150 volts. And 1100 volts means danger of death.
A current of 6mA across the heart will cause it to fibrillate. The voltage it takes to do that can be very low depending on where you are shocked and how you are grounded. If you are holding a conductor in your left hand and have your wet right foot on a ground conductor...
The minimum voltage it takes to kill you is roughly .006 x resistance to ground (in Ohms). Experimenting with this would be a VERY bad idea.
2nd Answer by ME plz recommend contribution
The correct answer is IT MAY AND IT MAY NOT. 1100 volts wont kill you unless the current is high. voltage X current = power(watt) an average light bulb operates on about 50-70 watts. So if the current is 0.000000001 amps, and 1100 volts you wont feel a thing. But on the other hand, 1 volt and 10,000 amps will fry your body instantly. So it all depends on the current. The actual voltage going through your skin is Voltage divided by resistance. Your skin's resistance is 100,000 OHMS so yeah you wont feel a thing if the voltage is too low. Also if it is AC(alternative current) it will do more damage to your body. If it is DC(direct current), then it does less. You can also go on youtube and search up 1 million volt tasers. they taze themselves and it will just sting a lot because that their tasers give off little current.
What size feeders for two 225 amp panelboards?
Use AWG #1 copper service entrance wire and #4 copper ground wire.
A sub-panel is always fed from a main panel. The main panel is situated where the electrical service wiring first enters the main structure on a dwelling plot or building site.
A sub-panel can be situated within the same building as the main panel or it can be in a subsidiary building or structure (such as a garage, garden shed or workshop) that is separate from the main building.
More information
A sub-panel is another name for a secondary breaker box, just as "the main panel" is another name for "the main breaker-box".
"Breaker-box" and/or "panel" are just alternative short names that are used instead of the full name "circuit breaker box".
How far can you run a 100 Amp main service line?
A Discussion has been started about this Question. To view it or take part click on the View Discussion button below. By asking this question you are probably not quite ready to take on this particular task. You may or may not get lucky and receive some information in an answer here! If you hope to get enough information on this site to be able to do this job properly and safely, please do not rely on getting accurate information about such a potentially dangerous subject. Really, don't do this one yourself. Electricity is far too dangerous to handle if you have not been trained how to do this work. If you put just one wire in the wrong place you risk being killed by electrocution or you could even start a house fire.
How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/State) and on the exact locations of the main service entry point and any outlets you wish to install. If they are anywhere subject to water splashes or spray - such as in any room supplied with running water pipes, like a kitchen, bathroom, shower room, etc., or in a pool-side area - in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician. If you don't want to go to your local library or bookstore - to find and read some books about electrical wiring and appliances and how to install them safely, and to find out about your local Wiring Codes and Regulations - then the best advice anyone should give to you is to call a licensed electrician either to do the job for you or to advise you what you may be allowed to do yourself.

If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work AND
always use an electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.
What size wire is needed to for 200 amp 240 volt house?
To keep costs down, by special permission in the electrical code, for home wiring on a 120/240 volt system 2/0 is allowed. For any other type 200 amp service 3/0 that has a insulation factor of 75 or 90 degrees C is rate at 200 and 225 amps respectively.
How do you upgrade a 60 amp service to 100 amp?
Get yourself an Quilified Electrician, The wire for the 100 amp fuse is going to be larger than what it would take for a 60 amp fuse so the wires are not going too fit in the 60 amp fuse properly Danger in more ways than one.
For a 150 amp service, you typically use a conduit size of 2 inches for copper conductors or 2.5 inches for aluminum conductors, depending on the number of conductors and the type of insulation. It's essential to check the National Electrical Code (NEC) tables for specific installations, as conduit fill requirements can vary based on the number of wires and their size. Always ensure to verify with local codes and regulations for compliance.
What size wire is needed for 1200 amp service?
This size service can be wired in a few combinations. Two parallel runs of 1250 MCM, three parallel runs of 600 MCM, four parallel runs of 350 MCM. Of the three choices the four runs of 350 MCM wires would be the easiest to handle if there are any bends in the service entrance conduit.
What size conduit for 200 amp service?
50 mm or 2 inch will handle the 3/0 wires for a 200 amp service.
Can you install electrical outlets in closets?
yes if it is fixed to the building so becoming the fberic of the building
How do calculate the size of a ground wire?
Assuming that the question is being asked about "dirt"; in the United States, the volume of dirt is calculated in cubic yards. In the rest of the world, the volume of dirt is calculated in cubic meters.
A cubic yard of dirt is the volume of dirt that fits in a space 1 yard (36 inches) by 1 yard by 1 yard.
A cubic meter is 1M X 1M X 1M.
What size wire will carry 100 amps 200 feet?
Wattage is really what is needed. If you are working with DC voltage, Ohm's Law is at work. But to answer your question directly probably a #4 wire.
<<>>
To answer this question the circuit's voltage needs to be stated. Then a voltage drop calculation can be made.
Can you use 2 GFCI outlets on the same circuit?
Yes, there are several ways to wire them. If you only want some plugs to be GFI (only the actual GFI plugs) protected then you wire them using just the "load" screws. if you want the whole circuit to be protected (or just two separate portions) the GFI plug must be first in the circuit and the protected plugs wired off of the "line" screws on the receptacle. Check the instructions, local codes, and with an electrician of course. Be safe, GFI circuits can be tricky.
How many amps does one kilowatt make 240 volts single phase?
There is one part of the question missing. To find an answer the kW of the heater must be stated. Then the equations used are, to change kW to watts, Kw/1000 = watts. Once that is found then use, I = W/E, Amps = Watts/Volts. This will give you the value in amperage of the heater.
What wire size for 3 phase 460 volt 30 amps?
A breaker is sized by the load current. A breaker is used to protect the load feeder from an over current being applied to the conductor. If the load draws up to 30 amps, the wire size needs to be a #10 copper conductor or larger depending on the distance to the load with an insulation rating of 90 degrees C. The 460 volt source has to do with the insulation rating of the conductor. In this case the #10 conductor will need an insulation rating of 600 volts. Do not use 300 volt rated wire.
How far can you run a 14 gauge electrical wire?
You can run it as far as you want, knowing that the farther you go, the more voltage drop will occur under load. If you have a very small load, you can run 14 AWG for hundreds of feet.
For instance, 14 AWG copper THHN 90C in conduit with 3 percent voltage drop would get you over 600 feet at 1 amp, but only about 50 feet at 15 amps.
How many outlets can you have on a gfi breaker?
Depends on the breaker. If the load at the outlets is unknown then the standard rules of 80% apply.
You can only load a circuit 80% of it's maximum value. For instance, if you're connecting your GFCI outlets to a 15 amp breaker you can only have a maximum of 12 outlets.
If it's a 20 Amp breaker then you're allowed up to 16 outlets and so on.
In the US, you are limited to 13 receptacles on a 20 amp circuit and 10 receptacles on a 15 amp circuit in commercial or industrial installations. Any or all of these can be gfci-protected. You can install one gfci, the first one from the panel, and protect any or all the others from that one.
Can a pull chain light switch be converted to wall switch?
The pull chain on the porcelain light fixture can be converted to a wall switch very easily. You will need to install a new two wire #14 cable from the box the fixture is mounted to now to the new wall switch box. Remove the power to the circuit by shutting that circuit's breaker off. The wire that is connected to the switch in the light fixture is the incoming "hot" wire. Disconnect it and re connect it to the black wire that goes down to the switch. Disconnect the white wire from the old porcelain fixture. For the installation of the porcelain fixture connect the white wire to the silver screw on the new fixture. Now connect the white wire that returns from the switch to the brass coloured screw on the new fixture. Mark this white wire with a small piece of black electrical tape to re identify it as not a neutral (code rule) but a potential "hot" wire. At the switch end make sure that the black wire is connected to the top screw and the re identified white wire (with a black tape marker) is connected to the bottom screw of the switch. Connect the ground wire in the cable to the new switch box and the existing fixture box. Install the switch making sure that the switch is in the off position and that the handle in facing downwards. Install switch plate cover, turn the breaker back on and you are finished. <><><> This project is relatively easy to do if there is already an existing wall box close to the pull-chain switch BUT ONLY if it already has the right wiring in it.
If there is no such wall box then a new one will have to be installed and wired. If you already know how to do that safely you would not be asking this question here!
For some relevant information, please see the related question below about replacing a wall switch by a pull switch. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

How do you wire a 4way switch?
Connect all white wires together under a wire nut and push them back into the box. Connect all ground wires together and then connect them with a jumper wire to the ground screw on the switch. Connect black power in and power out, if applicable, wires to the bottom screw on the switch. Connect the remaining black wire going to the light to the top screw on the switch.
What size wire do you need to run 100 ft 75 amp 230 volt?
Depends on the size of the circuit which you did not list.
What gauge ground wire should you use for grounding rod for 200 amp service?
Answer for USA, Canada and countries running a 60 Hz supply service.
Standard ground rod is 5/8th inch diameter and 8 feet long and the conductor connected to it is bare #6 AWG copper. Where I live we are required 2 rods, and NEC requires them to be placed a MINIMUM of 6 feet apart. These rods are treated in the NEC as SUPPLEMENTAL to a water line ground.

How many amps is a 12 gauge copper wire rated for at 240 volts?
Use a 30 amp breaker and 10 AWG wire for most applications. If you have unique requirements (high temperature, plenum, long run, etc.) contact a local electrician or your local building and zoning department.
How many watts of electricity can a typical windmill produce?
The typical wind system delivers roughly 8 to 10% of what systems are rated at 28 MPH. If the wind gusts over this amount the system shuts down. If the wind falls to 14 MPH you see 10% of rated. At 11 MPH you see nothing. To compensate for this issue, fossil fuel plants run in the background. The energy they use and CO2 output is ignored because wind generators are connected.
The overall effect is that no useful power is ever created if you consider the fossil fuel plants idling. Check out the number of birds killed each year by wind and you have a really bad system. They should be banned.
