New Electrical Work

The formula you are looking for is I = W/E. Amps = Watts/Volts.

For a 200 amp service running 650 feet, you would likely need at least 2/0 aluminum or 1/0 copper conductors for the hot lines. The size of the neutral conductor will depend on whether it is required to be the same size as the hot conductors or smaller, and the size of the ground conductor will need to follow local electrical code requirements. It is recommended to consult with a qualified electrician to ensure proper sizing for your specific application.

Would probably go with 10 gauge since 12 would do normally, a 275' length is a long run. Voltage drop would be a concern, especially if the load of the device had a high start up demand. Air conditioner, refrigeration unit, air compressor, etc.

To answer this question correctly a voltage must be given, since sizing the wire is all about voltage drop over a distance.

For a 100 amp service located 160 feet from the power pole, it is recommended to use 2 AWG copper wire or 1/0 AWG aluminum wire to ensure proper voltage drop and safety. Be sure to consult with a licensed electrician to determine the specific requirements for your installation.

The ampacity of 8 AWG aluminum wire can vary depending on the specific installation and code requirements, but as a general guideline, it can typically handle around 40-50 amps for residential applications. It's important to consult the National Electrical Code (NEC) or a qualified electrician for the most accurate information.

For a 200 amp service, a 250 MCM wire rated for 90°C can typically be run up to around 200-250 feet before exceeding voltage drop limits set by the National Electrical Code (NEC). However, it is recommended to consult with a licensed electrician to determine the exact length based on factors such as ambient temperature, conductor insulation, and specific installation conditions.

Fuses and circuit breakers are rated differently as applied to electrical loads. A motor load of 12 amps would require a fuse rating of 21 amps ( 12 X 1.75=21) or the next standard size of 25. A breaker for the same load of 12 amps would be a 30. (12 x 2.50=30) However if your circuit is number 10 copper wire and supplies 30 amp rated receptacles, you would be perfectly safe in using the fuses.

For a 12VDC system with 30 amps, you would typically use a wire size of at least 8 AWG (American Wire Gauge) to ensure it can handle the current without overheating. It's always a good idea to consult a wire ampacity chart to select the appropriate wire size based on the length of the wire run and the specific conditions of your setup.

Need to know what voltage the generator is outputing.

The maximum voltage a 15kW generator will support at 200A is dependent on service voltage and configuration, the rated generator voltage, the power factor and the load frequency. If this is a typical service to a residential unit, eg. 220V single phase, then the generator will not be able to safely support 200A.

As long as the breakers are made to fit the box, there shouldn't be a problem.

you can only use breakers listed for the panel, there should be a label on the panel door. It will list all of the breakers approved for use in that panel. If you don't see the breaker by manufacturer name listed, then it should not be used. Lots of brands will interchange, but they have to be listed to be approved.

A 16-gauge wire typically has an amp rating of around 10-15 amps, depending on the type of insulation and wire composition. It is important to consult the manufacturer's specifications or a professional electrician to ensure safe and proper usage.

No, it is not recommended to plug a 125 volt 30 amp plug into a 120 volt 30 amp outlet. The voltage difference may cause damage to the equipment and pose a safety hazard. It is important to use the correct voltage outlets for your devices.

MCB stands for Miniature Circuit Breaker, which is a type of electrical switch that automatically disconnects a circuit in case of an overload or short circuit. DP stands for Distribution Point, which refers to a location where multiple connections from a central source are distributed to different devices or equipment.

No, it is not recommended to connect a 2 pole load to 2 single pole breakers as this can cause issues with proper circuit protection and may lead to electrical hazards. It is best to use a dedicated 2-pole breaker for a 2 pole load to ensure proper operation and safety.

In the United States, there isn't a hard limit on how many 20 amp circuits that can be run on a 50 amp supply. This is because in most cases, especially in homes, we don't load most circuits with more than an amp or 2, even when they are protected by a 20 amp breaker. From a practical perspective you probably have a limited number of slots for breakers in your service or supply panel.

If the load is continuous you need to observe 80% rule. A 20 Amp breaker will handle short term loads that exceed 16 Amps. Think about it as a heat issue where continuous higher current will heat up components to unacceptable levels.

This is a voltage drop question. To answer this question a voltage has to be stated. The higher the voltage to the circuit becomes the smaller the wire size needed. After a certain voltage point the wire size will remain constant and the voltage drop at the load will become smaller.

The green and yellow striped color of the earth wire is an international standard to easily identify it as the connection for grounding in electrical systems. This color scheme helps to prevent confusion and ensures safety by providing a clear indication of the purpose of the wire.

For a 15 amp circuit over 200 feet, it is recommended to use a 14-gauge wire to ensure proper voltage drop. This gauge wire will help maintain the integrity of the electrical supply over that distance.

In the absence of better information and without testing it I would say yes, connect the black to the yellow. When you make decisions like this, be very watchful (as you should always be) when turning on the power so you can quickly turn it off if something goes wrong.

Not wanting to state the obvious but the wall switch has to be turned on to supply voltage to the outlet. The lamp will need a three way light bulb in the lamp. A three way bulb uses two filaments of different lengths. One element is used for low brightness, the other filament for medium brightness and the high brightness setting uses both filaments in the bulb. If a single filament ordinary light bulb is used in place of a three way light bulb there will be a position on the three way lamp switch where the bulb will not light. Find the position on the lamp where the bulb will light and leave it there. Use the wall switch to turn the lamp off and on through the controlled receptacle.

A three-way lamp switch requires a dedicated three-way bulb and socket to function on all three settings. If used in an outlet controlled by a wall switch, the voltage may not be appropriate for all settings to operate correctly. Additionally, the wiring configuration in the wall switch setup may not be compatible with the three-way lamp switch.

Trade size 1/2 inch EMT conduit will work just fine.

If conduit is not required, try 14/3 w/ground NM cable. I cannot use the name here but NM cable is that stuff that is used in homes all the time and starts with an R and ends with an x.

Trade size 3/4 inch EMT is about as easy to run as 1/2 so in the business we often run 3/4 because it doesn't sag as much and gives room for additional circuits later.

The cost of wiring a house in conduit would be so high the owner would crap.

That depends more on the current usage of each a/c unit than it does on the number of a/c units.

Check the current draw of each should be listed somewhere on the units. Add up the current draw, and don't exceed 80% of the rating of the breaker.
