New Electrical Work

For a 100 amp underground service to an unattached garage, you would typically need to use 3 AWG copper conductors for the hot wires and 3 AWG copper conductors for the neutral wire. This size will ensure that the conductors can safely carry the required current without overheating. Additionally, you may need to refer to local electrical codes and regulations for specific requirements in your area.

No, it is not recommended to use a 14-gauge Romex cable for receptacles. A 14-gauge wire is typically used for lighting circuits, while a 12-gauge wire is usually used for receptacles to handle the higher current requirements. It is important to match the wire size with the intended usage for safety and code compliance.

The maximum amperage for a 6-gauge copper wire can vary based on the insulation type and specific application, but it is typically around 75-90 amperes for general household wiring. It is important to consult the National Electrical Code or a qualified electrician to determine the exact amperage rating for your specific situation.

The temperature has no effect on the wire needed, only on the insulation and installation details. !70 A would require 35mm2 copper in free air. Soil disipates heat better than air, so the cable would take more current and be safe if it was in/on the ground. In any form of conduit, you'd need a bigger cable.

What voltage?

The load is a little over 2kW, so the output needs to be rated no less than 2.5kW continuous (assuming the load is continuous).

--------------------------------------------------------------------------

The voltage is regulated by the number of field windings versus stator windings, multiplied by the voltage added to the field from a DC source. Phase factors and operating power factors will also affect the total kiloVolt-Ampere output of a generator. this is often factored in for household emergency generators and a generalized rating is given for a 220 volt output. for a 2049 watt load at 220 volts a single phase generator with with an output of 2500 watts or more should be used. The phase factor would be 1:1, power factor negligible (unless hooked to the power grid), and motor(generator) efficiency is about 96% typically. Adjusting for a 25% peak load (when items turn on and off) then:

(2049w/0.96)x1.25 = 2668 watts , a 2500 watt generator will handle it if not all things attached to it start at the same time.

This is equivalent to a 100amp circuit load at 220 volts or 200amps at 110 volts. (circuit breakers), most houses require a 200 or 300 amp service (add up all the circuit breakers in use in the box.)

note: single breakers are typically 110 volt and double breakers are typically 220 volts, when adding up breaker's amperage double the load for double breakers to compare the loading at 110 volts.

example:

Circuit box has 2 double (220v) breakers, stove/oven 30 amp, water heater 45amp, and 12 15 amp single breakers (110v) the total load for the service is:

(30 x 2)+(45 x 2) + (12 x 15) = 330 amps (@110 v) or 165 amp service (@220v)

165 amps x 220 volts = 33000 volt-amperes , because emergency generators are rated at 220 volts the kilowatt output needed is 1.65 x 125% = 206.25 kw @ 220 volts

For industrial generator ratings: volt-amperes = kilowatts x power factor x phase factor (3 phase generation phase factor is 1.732, power factor is adjusted by adjusting the field voltage) , these do not apply with emergency generators. {volts x amperes = watts}

Yes, you can convert a hanging chandelier wired for European currency to be used in the US by changing the wiring to accommodate the US voltage (110-120V) and plug type (typically Type A/B). This may involve rewiring the chandelier or using a voltage converter depending on the electrical specifications of the fixture. It is recommended to consult with a qualified electrician to ensure the conversion is done safely and correctly.

The amps on any wire is determined by the voltage and the load that is being served. If you are asking what is the maximum current allowed on a #8 AWG, that would be 40 amps for a 60 degree Celsius rated wire, 50 amps for a 75 degree Celsius rated wire and 55 amps for a 95 degree Celsius rated wire.

Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.

THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor. Romex is a brand name for a nonmetallic sheathed cable, it has multiple conductors inside, the insulated ones are insulated with THHN insulation.

For a 200 ft distance, you should use at least a 8 gauge wire to minimize voltage drop and ensure safe operation for a 30 amp, 110 volt circuit. It is important to consult a licensed electrician to determine the specific wire size needed based on the load and local electrical code requirements.

If you draw one amp of power for 1 hour that is an amp hour . If you have a different load eg a heater drawing 3 amp , it would be 20 minutes . Divide the hour ( 60 mintues ) by the amps you draw .

Materials like metals (such as aluminum, copper, and iron) are good conductors of electricity. In the kitchen, items like pots and pans made from these metals can conduct electricity well. It's important to note that water is a good conductor of electricity too, so caution should be taken around electrical appliances in the kitchen.

the wire size should be appropriate for the maximum current the device will draw to prevent overheating or voltage drop. It is important to follow electrical code and safety guidelines when selecting a wire size for a line cord. Consider factors such as voltage, current, and length of the cord when choosing the appropriate wire size.

A volt-amp or VA is equivalent to watts, provided the voltage and amperage are in phase. So 1 kilo volt amp is the same as 1 kilowatt.

Wattage, or power, is equal to volts times amps.

So the original question is effectively nonsense. The number of amps depends on the voltage. If the voltage is 1000 volts, then there's 1 amp in 1 kilo volt amp. If the voltage is 1 volt, then there's 1000 amps. If there's 50 volts, then the amperage is 20 amps. And so on.

For a 200 amp breaker box, it is recommended to get a generator that is at least 22,000 watts to provide enough power to cover the peak load. This size will ensure that your essential appliances and circuits can be powered during an outage without overloading the system. It is always best to consult with a professional to determine the specific needs of your home.

A 15-amp time-delay breaker is a type of circuit breaker that is designed to handle electrical currents up to 15 amps and can tolerate temporary overloads without tripping immediately. This delay feature allows for short-duration surges often found in appliances like refrigerators or air conditioners.

It is recommended to limit the number of 90-degree bends to 360 degrees in one run from Box A to Box B to prevent excessive resistance and impact on cable performance. This means you can have up to four 90-degree bends in a single run.

Yes, for most switches and outlets in the US, the neutral wire (typically white) connects to the silver screw. The hot wire (typically black) connects to the brass screw, and the ground wire (typically green or bare) connects to the green screw.

Amps measure the current flowing in a circuit, watts measure power output, and volts measure voltage difference. In an electrical system, volts x amps = watts, so they are related but measure different aspects of electricity. Volts represent the force pushing electrical current, while amps indicate the rate of flow, and watts show the total power consumed or produced.

A good height for an exterior electrical outlet box on a post is typically around 18-24 inches above the ground. This height allows for easy access to plug in various devices, while still keeping the outlet elevated to avoid potential water damage or debris. Ultimately, the height may vary depending on local building codes and personal preference.

A 15000 BTU air conditioner typically requires around 12.5-13.5 amps to operate efficiently. It's important to check the specific specifications provided by the manufacturer to get an accurate value for your particular air conditioner model.

The AC unit is fully controlled by the contactor. If the unit turns off by thermostat control such as setting tstat to off, the contactor is ok. The thermostat could be the problem though. yeah i understand that but when i say old unit i mean its so old that the thermostat only have two cables the red one and the white one! the auto and cont the unit has it in the indoor unit!!!

Watts = Volts x Amps, if you use your algebra you will find that it's approx 14 Amps.

A #10 copper wire with an insulation rating of 90 degree C is rated at 30 amps. If the heaters exact draw is 30 amps then go to the next wire size. That will be a #8 copper wire with an insulation rating of 90 degree C and it is rated for 45 amps.
