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.
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.
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.
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.
You will need a 40 amp breaker using AWG # 8 wire running it a distance of no more than 50 feet.
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.
For an accurate calculation it will be necessary to know what the size of breaker exists in the pump house and what size conductors are used. Power loss is measured using actual amps required, not size of the circuit involved. But the size of circuit (breaker size) can be used. Voltage must also be known.
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.
The sizing of the circuit breaker and hence the wire size to feed the pump are all dependant upon the amperage of the pump. This question can not be answered without that information.
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.
50amp but if considering the breaker cannot withstand starting current you need to size the breaker up.
Depends entirely on the voltage and current rating of your pump.
25 cubic feet
You need a 60 amp breaker.
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.
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.

The rule of thumb is 2-1/2 tons per 1000 square feet.
