How do i convert a table lamp with a twist knob to a chain pull switch?
Most Home Improvement stores sell a pull chain kit that can be used for the conversion. Instructions would show how to install not convert. Another way that shouldn't cost much is to find a chain pull switch lamp being throw away and take it for yourself. Consider this the dissecting of the lamp to understand what components are going to match up on the table lamp. Swap them out and make sure all connects are not worn, burned or charred.
A short answer to this question is: the purpose of the third wire is that it is installed to provide a safety wire that will carry any ground current if a fault condition occurs.

There are two main types of cables used in home wiring for the secondary branch circuits. One is a two wire cable and the other is a three wire cable . Whenever these cables are referred to, the bare ground wire is not included in the wire count as it is not a current carrying conductor. Most predominant is the two wire cable used for most circuits. The use of the three wire cable is for split kitchen receptacles and wiring of three way switches. In a big sq foot area home, three wire cables are sometimes used to take two circuits to the other end of the house instead of using 2 two wire feeders. These types of circuits use the common white wire for the neutral and the red and black wires for the two hot circuits.

What gauge of electric wire needed for a 160' run at 125 amps?
For a 160' run at 125 amps, you would need at least a 2-gauge wire to minimize voltage drop and ensure safety. It's always best to consult with a qualified electrician to confirm the appropriate wire gauge for your specific situation.
What size amp circuit breaker should be used for a air conditioner?
In the USA, a National Electrical Code specifies things like circuit breaker sizes. The purpose of the circuit breaker is to protect the wiring (which is usually in a metal or plastic conduit, or in its own plastic insulation, and also is usually hidden in the wall, ceiling, or floor). The size of the circuit breaker (such as 15-amp, 20-amp, 30-amp) depends upon the size of the wiring.
Wire guage sizes (in USA) are typically 14 awg (for lighting and light-duty circuits up to 15 amps), 12 awg (bigger than 14 awg, for power outlets as well as lighting circuits up to 20 amps), and larger sizes for special purposes.
Most modern kitchens have two or more 12 awg circuits for the purpose of providing power to appliances such as toasters, mixers, etc. A 20-amp circuit breaker would protect a 12 awg wiring system designed to carry 120 Volts and 20 amps (amperes).
For safety, you must determine the size of the wiring in order to decide which size circuit breaker will protect it.
15-amp circuit breaker for 14 awg wiring (which is easy to bend with finger tips) 20-amp circuit breaker for 12 awg wiring (which is hard to bend with finger tips) 30-amp circuit breaker for 10 awg wiring (which is very hard to bend with finger tips)
The appliances and other items that you plug into an electrical outlet rely upon their own fuses or other design features for protection. The circuit breaker protects the wiring to prevent fire. This is IMPORTANT. Do not use a larger circuit breaker than the wiring can safely handle.
AWG = American Wire Guage Smaller numbers are for bigger wires. 6-awg is about as big as a wooden pencil. 30-awg is about as fine as a human hair.
I would add this: do yourself a favor, make 12 gauge wire your standard when putting in any new wiring (unless you are going higher than 20 amp circuit) . Don't mess with 14 gauge at all. The cost difference is peanuts.
How do you determine best gauge of wire to use?
There is a formula based on wire type, length, and current. The easiest way nowadays is to use an online calculator. Remember when using that calculator that both wires in the circuit count (hot & neutral), so don't divide the length by 2. Just enter the length of your run.
What is code for electric outlet height outdoors?
Outdoor receptacles shall be installed outdoors so as to be readily accessible from ground or grade level. All outdoor receptacles located within 6 feet of ground or grade level shall be protected by a GFCI (Ground Fault Circuit Interrupter of the class A type.
What are those things on the wall to plugs vaccumn plugs in?
These are direct connect ports, used in a central vacuum system. They are available powered (for use with an electrical vacuum head) or unpowered (suction only)
In electricity is stands for Ampere which is the basic standard for measuring current. It is the measurement of the amount of electric charge (electrons) passing a set point over time.

In electronics is the short form of amplifier.
ma stands for milliamp. The prefix 'milli is equivalent to .001 So 1 amp would be 1000 milliamps and 20 milliamps would be .02 amps
Shut the GFCI off at the panel breaker. You can remove the down stream load right at the GFCI. Then reapply the power and keeping your fingers clear of the wire terminals, trip the GFCI and reset it. If it stays reset the trouble is down stream from the GFCI. To trouble shoot down stream remove all plugged in devices and try a reset. If still no reset remove the hot wire in the hard wired fixture and try for a reset. If still no reset buy a new GFCI.
The unit of work is called a joule. It is a derived unit of energy in the International System of Units (SI) and is defined as the work done by a force of one newton acting over a distance of one meter.
If a duplex wall receptacle the side with the larger hole should be wired to what?
The white neutral wire connects to the silver colored screw, large hole. Black hot goes to the brass colored screw, smaller hole size.

How much weight can you hang from a standard electrical fixture for hanging lights?
It is not recommended to hang any weight from a standard electrical fixture meant for hanging lights. These fixtures are designed to support the weight of the light fixture itself, not additional weight. It is important to follow manufacturer guidelines to avoid damage or safety hazards.

How do you dedicate a wall outlet?
To dedicate a wall outlet means to reserve it for a specific purpose or appliance. This can be done by labeling the outlet or installing a dedicated circuit for that outlet to ensure it has its own power source separate from other outlets in the room. It is important to follow electrical safety guidelines when making any changes to your electrical systems.
Where does the switched live go in a ceiling light?
The switched live wire in a ceiling light typically connects to the live terminal of the light fixture. This wire carries the electrical current and is controlled by the light switch to turn the light on and off. Make sure to turn off the power before making any electrical connections.
How do you wire a cooker stove oven or range outlet?
I assume you are going from electric to gas. You can derate the outlet or run a new one. You should seriously consider simply adding a new outlet behind the stove so you can easily go back to electric.
What wire size is needed to run a 100 amp subpanel?
For a 100 amp subpanel, you would typically need to use #3 AWG copper wires for the hot conductors and a #8 AWG copper wire for the ground conductor. The size of the neutral wire would depend on whether the subpanel will be used for 120 volts or 240 volts.
Converting a pump motor from 110 to 220v 2 hot leads and a ground is there any use for the neutral?
No, the neutral wire is not needed for a 220V setup as it is a single-phase system. The two hot leads will supply the necessary power for the motor, while the ground wire is for safety grounding purposes. Always refer to the motor's specifications and local electrical codes when making such conversions.
Can you use copper tubing as decorative electrical conduit?
Yes, copper tubing can be used as decorative electrical conduit, but it must be properly insulated and grounded for safety. Additionally, it's important to ensure that it meets local building codes and regulations for electrical wiring.
What is the price to install an electric socket?
I charge $25 each, with a minumum of 5 duplex receptacles (new 3-hole house sockets) replaced. There are almost always other problems, broken screws, missing cover plates, etc. that Must be taken care of. This is extra, usually $5 ea. By: Illinois Construction Co.,Inc.
How much does amperage drop with distance?
Amperage drop with distance depends on the resistance of the conductor and the load. As distance increases, resistance increases, leading to higher voltage drop. This can result in lower amperage at the end of the circuit compared to the source. Use Ohm's Law (V=IR) to calculate the amperage drop based on the resistance and distance.
You can install a 200 amp sub panel near the existing sub panel at the other end of the house. This will allow you to upgrade to 200 amp service without rewiring the entire house at once. Be sure to consult with a licensed electrician to ensure the installation is done safely and up to code.
What size wire for a 60 amp breaker?
For runs under 75ft 4 gauge wire is recommended. For runs over 75ft consult a wire size calculator. Remember that the total circuit length is twice your run. (length of Hot + length of Neutral) Don't divide your run length by 2.
