A #8 copper conductor with a 90 degree C insulation factor is rated at 40 amps.
The size of the amp circuit breaker needed for a geyser will depend on the specific electrical requirements of the geyser. It is important to consult the geyser's manufacturer specifications to determine the appropriate amperage for the circuit breaker. Typically, a 20-amp circuit breaker is commonly used for residential geysers, but larger geysers may require a higher amperage circuit breaker. It is crucial to ensure that the circuit breaker is properly sized to prevent electrical hazards and ensure safe operation of the geyser.
Wire and breakers are sized depending on the current that is to be applied to the circuit. To answer this question a voltage is needed to divide into the kilowatts to obtain this amperage. I = W/E. Once the amperage is obtained a table in the electrical code book is used to establish what the breaker size and wire size should be for that particular amperage.
The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.
The use of a breaker in a circuit is to protect the wire size used in the circuit from becoming overloaded. Using the wattage of the load does not help for breaker sizing because the breaker operates on amperage. Amperage can be found from wattage by using the following equation. I = W /E. Amps = Watts / Volts. As you can see the amperage can not be calculated because there is no voltage stated.
The size of the circuit breaker for a pool pump should be determined by the pump's current draw. The breaker should be sized to accommodate the pump's full load amperage with a 125% safety margin. Most pool pumps typically require a 15 or 20 amp circuit breaker.
For a 240-volt circuit that requires a 50 amp breaker, the appropriate size of the breaker needed is 50 amps.
Typically yes because that is what makes sense. However, the subpanel could have the same size breaker as long as the panel were rated for that amperage and the wire sizes were appropriate.
The amperage limit for a circuit is determined by the wire size and the rating of the circuit breaker. It is important to use the correct wire size and breaker to prevent overheating and potential fire hazards. It is recommended to consult a professional electrician to ensure safety and compliance with electrical codes.
If the question means "two loads in one circuit" then the load currents have to be added together. The breaker that protects the circuit is sized for the total loading of the circuit. These two loads of course will be in parallel with each other. Find the wattage of the two loads if the amperage is not available. The equation is W = A x V. Watts = Amps x Volts. Once the total amperage of the circuit is found select the correct wire size for that amperage. The breaker protects the wire size so then select the proper breaker for that wire size.
For a 120-volt appliance, a single-pole breaker with a rating suitable for the appliance's power requirements should be installed in the electric box. The amperage rating of the breaker should match the current draw of the appliance to ensure proper protection and operation. It is important to consult with a qualified electrician to determine the appropriate breaker size for your specific appliance.
It depends on what the amperage of the motor is. The motors amperage depends on the voltage of the motor. The higher the voltage the motor operates on the lower the amperage. So unless the amperage from the motor's nameplate is stated an answer can not be given.Just remember that the feeder capacity to the motor has to be 125% of the motors full load amperage and the breaker protecting the conductors to the motor has to be rated at 250% of the motors FLA. This higher breaker size allows the motor to start without tripping a normal size breaker that is rated for the lower conductor size.
This is determined by the size motor and the amount of amps the motor draws, be on the safe side and consult the owners manual or an Electrician. <<>> The sizing of the breaker and feeder wire is based on the amperage of the compressor. Look on the name plate and find the amperage. The amperage on the nameplate then has to be multiplied by the motors full load amperage and that value is used for the wire size. Because the load is a motor the FLA is again multiplied by 250% to size the breaker. This takes into allowance the high starting current of a motor from 0 to 100% RPM.
