Yes. Get a volt meter and check the power at the timer. It sounds like you have a switchless motor with a bad run capacitor and a week breaker. That's about a $20 fix.
Check power on line 1 line 2 with the meter set at around 500 volts a/c- you should get 230 or so, most pumps are 230 volt. Another thing- if it has a skinny breaker, 115v if it's a wide breaker, 230v.
Step 2 Take the motor to a qualified repairman, as they will usually test it for free.
If you are uncomfortable with your lack of electrical experience, make step 2 your step 1.
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
A circuit breaker/fuse is designed to protect the wiring from getting overloaded.
12/2 wire with a 20 amp breaker for normal home wiring.
A circuit breaker, or a fuse.
The circuit breaker is self resetting. you may have a short in the wiring.
Conduit wiring is synonymous to wires in a pipe.
If you are referring to house wiring then the answer is no. A breaker protects the wire size that is connected to the breaker. In home wiring most homes are wired with a #14 wire which is rated at 15 amps. That is why the wire is protected by a 15 amp breaker. The correct wire size to connect to a 40 amp breaker is a #8. This size wire is too large to connect to receptacles an light fixture terminals.
A short circuit in the wiring or in the switch.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
The wiring is like this:[[30KW Motor ---- Star Delt Starter(100A Breaker inside) ----- 200A Breaker------50A Breaker(Inside the breaker box which located inside the factory) -----100A Main Breaker]]Once I try to start the Motor, the Main Breaker trips immediately.
You need to remove everything connected to the breaker and see if it still trips. If it does it is in the wiring or possibly a bad breaker. Disconnect load from breaker and see if it still trips. If so replace the breaker. If it still trips and is not the breaker then you will have to start pulling each outlet from wall and checking after disconnecting each outlet.
You use the correct size breaker that matches the wiring. The correct amperage will be listed in the owners manual for the tub.
