What is the relationshi between a motors service factor and amperage rating?

A motor's service factor is a multiplier applied to a motor's horsepower rating to indicate the level of overload it can handle. The motor's nameplate amperage rating indicates the maximum current it should draw under normal operating conditions. The service factor does not directly impact the amperage rating, but motors with a higher service factor may be capable of handling higher loads and thus draw more current.


How many amp is 21 volts?

To calculate the amperage, you need to know the resistance in the circuit. Amperage is calculated using Ohm's Law: Amperage (A) = Voltage (V) / Resistance (R). Without knowing the resistance, we cannot determine the amperage.


How can you tell what your home amp service is?

Look on the handle end of the main breaker. There should be a number there. That is the amperage of the main breaker. That is the size of your house service.


Can you hook up 200 amp dervice to a 125 amp service panel?

No, it is not safe or recommended to connect a 200 amp service to a 125 amp panel. The panel must be rated to match the amperage of the service to avoid overloading the panel and potential fire hazards. It is important to upgrade the panel to match the service amperage.


What 3 phase cable do you use if the building is 160 meters from the power pole?

This is a voltage drop question. To answer it, a voltage of the service and amperage that the service is going to be have to be stated


What amperage service is needed for central air conditioning unit?

30 to 50 amps, it should be dedicated for the A/C.


If a heater takes 1200 watts at 120 VOLTS what would the amperage be?

I don’t know


Can you use a 1200amps service if you have a 1000amps on service?

No, you should not use a 1200amp service panel if your service is rated for 1000amps. Installing a panel with a higher amperage rating than your service can handle may lead to electrical safety hazards and code violations. It is essential to match your electrical service to the appropriate amperage for safety and compliance.


How many amps is 2kw?

To calculate the amperage for 2kW, you need to know the voltage of the circuit. For example, if the voltage is 120V, then the amperage would be 16.67A (2000W / 120V = 16.67A). If the voltage is 240V, then the amperage would be 8.33A (2000W / 240V = 8.33A).


What is the minimum size neutral for three sets of parallel 500kcm copper conductors for a service?

On large service entrance services the neutral can be reduced. The amperage of the service and the voltage of the service and the insulation factor of the 500 MCM conductors need to be stated to answer this question correctly.


If kilowatts are known how to you find the proper wire size?

Wire size needed depends on amperage, not watts. If you know the voltage of the power supplied you can calculate the amperage using this form of the "power formula":A = W / VThen there are tables that tell the amperage each wire gauge is capable of carrying. Just select the gauge that has the amperage rating just larger than you calculated.
