It is probably only getting 115V from your circuit which will cause it to overheat and trip the overload yet it will not draw high current which would trip the breaker. Can you confirm your line voltage with a meter? If it is suppoed to be a 230V line then look for a bad leg of power, again, checking each leg to ground using a meter.

I have a brand new 1 1/2 hp superflo. I wired it in and turned on the power, it hummed for a few secounds and trip the breaker. now it it wont work and just immediatly trips the breaker. Any ideas as


It sounds like the motor shaft is stuck. The back end of the motor has an end cap that comes off so you can access the end of the motor shaft. Try this with the power off; Remove the cap (center rear of the motor),Using an open ended 9/16 wrench you should be able to turn the shaft back and forth. A motor that has sat for a while will sometimes act like yours did. A nudge with the wrench usually breaks it free. Remove your wrench and turn pump on. If it still won't start the motor may be defective.

Water heater


Guessing that you have 240Volt residential non-simultaneous electric water heater? And that you have 30 amp breaker and 10 gauge wire. And that water heater is located within 100 feet of breaker box. And there are no leaks running hot water out of tank. And that you installed fully brand NEW elements of same wattage as old elements. And that fully brand new thermostats were installed, and wiring exactly duplicates wiring that was present before. And that factory-insulation was re-installed over elements and thermostats.

1) Guessing the 'hot water shut off' means the ECO red reset button located on upper thermostat keeps tripping and cutting off electric power to water heater?

http://waterheatertimer.org/images/WH-w-combined2-1000.jpg
http://waterheatertimer.org/How-to-test-water-heater-wires.html

2) If the ECO is tripping, then water is getting too hot, or there is shorted wire located near the upper thermostat, .
Typically replacing both thermostats and replacing elements will solve this problem .... assuming that new thermostats and elements are good, and wiring correct.
Double-Check your wiring on upper and lower thermostats.
Test wires for short.
Make sure factory-insulation is re-installed over thermostats so cool room temperature will not affect temperature reading.
Check that thermostats sit flat against steel tank.
Many short draws hot water can also cause stacking event that will trip circuit breaker.

3) Add comment and say what you find using checklist above.
Be careful to explain findings fully, using same words found on links above, so illuminated diagnosis can be made.

Why is my 50 amp GFIC breaker tripping out? I have just installed a new hot tube.I had one there before(smaller 40 amp) so there was already #8 wire there.The new hot tub requires a 50 amp. #6 wire. I just...


There might be a few things here:

1) Big problem >> the #8 wire is a fire hazard connected to a 50Amp breaker

#8 is a 40 amp breaker
#6 is a 55 amp breaker
We put #6 on a 60 amp breaker
Are you saying you hooked the #8 wire to the new 50 amp breaker, and the hot tub called for #6 wire?

Upsize your wire and breaker to meet code
http://waterheatertimer.org/pdf/Wire-size-amp-rating.pdf

2) After putting the correct wire and breaker, you can still have a short in the circuit somewhere
We used to set equipment out in the field in early morning >> the grass was wet >> our equipment was fine, but the tiniest short would cause the GFCI to trip

I don't know where the problem is without a thorough checkout of every possible grounded surface. You need a good multi-meter

3) You better get an electrician over there to have a look before the place burns down or somebody wakes up dead in the hot water.

If I sound a bit scary here, it's because something doesn't sound right with your installation.

1 1/2 HP Pentair Pinnacle Pump keeps tripping the breaker. What would the problem be and how can I fix it?


The motor and/or electrical system is damaged and need to be repaired. With the breaker off, disconnect the motor and insulate the wire ends. Turn the breaker back on and it should remain closed without tripping. If so, it is ok and you can turn it off and leave it so until the motor is fixed or replaced.

Find a local electric motor repair shop and have them inspect the motor. It will likely have to be replaced but taking it to them insures it is not repairable and also makes sure the new one will fit correctly. A new motor and seal would likely run ~$150 or so.
