What size wire do you need to run a 220 pump 40 amp breaker 130 feet?

This is a tricky question to answer without all of the information necessary for calculations. A motor has to have a breaker sized at 250% of the motor's full load amps. Wire is sized by the amount of amperage that it is allowed to carry.If the breaker is sized at 250% then the motor's full load amperage must be 16 amps if this is the case then the conductor for 16 amps at 130 feet will be #12 copper or #10 aluminium. the insulation rating for the conductors must be 90 degrees C.
If the motor's full load amperage is 40 amps then the conductors, both copper and aluminium must have an insulation factor of 90 degrees C ad the wire size will be #6. The breaker for this pump must then be a 100 amp breaker. The larger size breaker is used so that it does not trip due to the inrush current when the motor starts. It could be in the range of 300 to 600% of the motors full load amperage.

Can a 220 Volt well motor be added to a 200 amp box or does it need its own box?
The well pump breaker is installed in two slots in your breaker box. You then run the correct size cable for the amperage of the pump to the area where the pressure tank is located. install a breaker or disconnect on the wall near the pressure tank and then connect the low pressure switch to the disconnect. Connect the pump to the low pressure switch.
Do i need to switch circuit breaker since i went from 115V well pump to 230V well pump it is also a higher HP pump but pressure is lower than before?
The 230v breaker is 2-pole, The 115v is only single-pole so YES you need a new breaker. DON'T use 2 single-pole breakers instead. The well pump will run to the pressure setting of the pressure switch controlling it, regardless of HP. The difference might be in the size of the pump in flow rating, I.E. a 1/2 HP pump rated at 10gpm @ 70 psi won't perform the same as a 3/4 HP pump rated at 20 gpm @ 50 psi. Check the pump curve and pressure switch setting. The pressure switch for the new pump will need both power leads connected to the switch (1 lead per contact set), not 1 wire as the 115v motor was.
What size breaker do you need for two 60W bulbes 110 volts?
It is not the number of bulbs that you worry about. It is the wire size that is your concern. If the circuit is wired with AWG 12/2 wire then use a 20 amp breaker. If it is wired with a AWG 14/2 wire then use a 15 amp breaker. You are protecting the wiring with the correct size breaker.
What size in square mm copper wire will be required to carry 26 amps?
You will need a 40 amp breaker using AWG # 8 wire running it a distance of no more than 50 feet.
What size breaker do you need for 9000W at 440V 3phase?
This formula will give you the amperage I = kw x 1000/1.73 x E x pf (pf = power factor). Take the amperage and multiply it by 125%. This will give you the breaker size that you need.
What size breaker does it take to run a outdoor well?
Normally AWG #10 wire on a 30 amp breaker but it really depends on the size of the pump. The pump manufacture will specify the size wire and size breaker needed.
What is the breaker size for a goulds century pump 1081?
The breaker size for a Goulds Century pump 1081 would depend on the specific model and voltage requirements. Refer to the owner's manual or the nameplate on the pump motor for the correct breaker size recommended by the manufacturer. It is important to match the breaker size with the electrical requirements to ensure safe operation.
What size in amperage circuit breaker should be used for a pool pump?
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.
What size breaker do you need for a well pump?
A breaker is based on the amperage that is drawn by the pump motor load. Find the full load amperage of the motor. The wire fed from the breaker has to be rated at 125% of the motors full load amperage. The breaker for motors have to be over sized, usually 250% of the motors full load amps.
What size breaker do you need for 9000W at 440V 3 phase delta?
50amp but if considering the breaker cannot withstand starting current you need to size the breaker up.
What size heat pump do you need for a 1400 sq ft home?
25 cubic feet
What size circuit breaker to use on well pump?
To determine the correct size circuit breaker for a well pump, you should check the manufacturer's recommendations on the pump's label or in the manual. Typically, most well pumps require a 15-amp or 20-amp circuit breaker for residential use. Make sure the breaker is appropriately sized for the pump's power requirements to avoid damage or safety hazards.
How much loss from power pole to 200 amp breaker box then off 400 feet then split at a pump house then another 30 feet to a 100 amp breaker box?
The loss of voltage over a distance depends on factors such as wire gauge, current flowing, and resistance. For a 200-amp service at 400 feet and then branching off another 30 feet to a separate 100-amp service, there could be a noticeable voltage drop. It is recommended to consult with a licensed electrician to calculate the exact voltage drop and determine if any voltage compensation measures are needed.

The well pump breaker is installed in two slots in your breaker box. You then run the correct size cable for the amperage of the pump to the area where the pressure tank is located. install a breaker or disconnect on the wall near the pressure tank and then connect the low pressure switch to the disconnect.

What size heat pump for a 18x33x4.5 deep above ground pool?
The size of a heat pump that you can use for a pool which is 18 feet wide by 33 feet long and has a depth of 4.5 feet can vary depending on specific brand of heat pump you wish to purchase. The minimum size of heat pump for an above ground pool of this size in 102,000 BTU.
What size wire do you need to wire a 200 am breaker box?
6
What size of heat pump will you need for a 2400sf home?
The rule of thumb is 2-1/2 tons per 1000 square feet.
