HAVE A LOOK INSIDE THE MOTOR CONNECTION BOX. SOMETIMES ON THE LID ARE INSTRUCTIONS OF HOW TO DO THIS. YOU DID NOT SAY IF THIS WAS A CAPACITOR START UNIT OR NOT. IF THERE IS A CAPACITOR ON THERE IT COULD BE NO GOOD WHICH WILL MAKE THE MOTOR GO WHERE IT WANTS. A GOOD CAPACITOR KICKS IT IN THE RIGHT DIRECTION ON SWITCH ON.

SOURCE: how to wire a t30

yes white and black are both line voltage in.each wire will have 110 to 120 volts. Attach one wire to top of starter contactor left side the other to top of starter contactor right side. Attach green wire to ground.

The unit rated at 3 HP at 115 volts draws 13.8 amps is odd, a HP in watts is 745 and should be about 2200 watts and 19 amps plus a efficiency loss. Odd to see the ratings don't jive with electric theory/formulas.

The compressor should be connected directly to the wall and if using an extension cord, the cord needs to be #12 AWG or larger to avoid line voltage loss and over amping of the motor.

Here is contact and support info: For more information, please call 800/4-MAKITA (800/462-5482) or visit makitatools.com.

My bottom line is, A 115V motor circuit needs 10 amperes per horse power or 30 amp circuit for 3 horse power. Using extension cords calls for upgrade in wire gage of the cord. The advantage of using 230 volts is it cuts the amperes in half and allows use of smaller gage wire. Watts, or volt amperes is the product of volts and amps.

The control fuses keep blowing tells me one or more of the control that operate the control on 24 volts is malfuctioning. Most controls operate at about 5 watts and on a clamp on amp meter normally pull about 0.2 amp (p = current x voltage, 5 watts = 0.2 amps x 25 volts) I install 75 watt 24 volt transformer with a resettable overload to save on fuses. I reset the transformer and quickly go to the controls and determine the amp draw. When I find the one >0.2 amps I found the problem. The things to check is the emergency heat sequencer, fan control sequencer, reversing valve for heat pumps, main contactor on the condensing unit and any other 24 volt control loads. I have had to replace the themostat wire because the increase current for the thermostat wire can cause the entire length of wire to form a long heater and cause insulation degradationa and cause the thermostat wire to short out and blow the fuses.

Hope this helps

On an electric furnace multiply the volts times the amps and you will get watts.Then multiply the watts x 3.143 and that is your BTU

Check circuit breaker.

Click fully off and then back on.

Check for burned smell at breaker or loose crackling sound that says breaker is bad.

Reset timer. Then Reprogram.

Possible geyser timer manual

http://waterheatertimer.org/pdf/Digital-Geyser-Timer 24H-7-Day-Timer-230V Brochure.pdf

This timer has a non-replaceable internal rechargeable battery.

If battery has gone bad, then timer is defunct.

Use manual override button to turn timer ON-OFF.

Then test across terminals 3 and 4 for 240Volts.

Turn timer OFF, and test across terminals 4 and 5 for 240Volts

If no voltage shows then timer does not have output.

If test shows 80% undervoltage, that can cause load not to activate, depending on type of load.

Have electrician check for voltage issues at power company transformer.

Unknown what load timer is connected to.

Max load for this timer at 240 volts is 3680 watts, 16 amps.

Motor load is 230 volt 8 amps.

Check label on load for watt or amp rating.

Volts x amps = watts

Watts divided by volts = amps

The simple answer is not many. I don't think your pump is that hungry to use kilowattS per hour... lets see "Kilo" is one thousand. At this site you will find the several formula for getting to your answer. Ohm's Law applies ... http://www.powerstream.com/Amps-Watts.htm

I am presuming your pump is 115 Volts and it probably plugs into a 15 amp circuit. IF IT USES 15 amps (I doubt it uses the entire value) Volts X Amps = Watts or 1725 watts or about 1.7 kilowatt. I couldn't find the amp rating for your particular model pump. I think it probably operates near 6 to 8 amps @ 115 Volts AC. If your pump runs at 6 amps that is 690 watts, 8 is 920 and 10 would be 1150. There are other factors that determine the actual amount of power consumed - load will increase the use - partially clogged filter would be an example of increased load, age of the pump could be another factor.

Here is another nifty place to convert: http://www.supercircuits.com/resources/tools/Volts-Watts-Amps-Converter

Here is a rule of thumb: If a device can run on two different voltages, the higher the voltage, the lower the amps. For example 115 volt @ 12 amps would use 1380 watts. The same device running at 230 volts would run at 6 amps and use 1380. This is the correct math answer. However, in actual use, the device would run slightly more efficient (use fewer watts). Electricians and science teachers and math teachers will all tell you different stories depending on their discipline. Heavy use devices do run more efficiently at the higher voltage (stove, dryer, furnace, hot water heater, well water pumps, swimming pool pumps)(Do not go looking for a 220 Volt pump for your above ground pool in an effort to save money. The higher voltage device will cost more and there are other practical and safety related issues in this kind of installation.)

If you lived in my area, (please don't say where you live) you would pay about 12 cents (US dollars) per kilowatt hour. If your pump runs at 10 amps 115 volts - that would be just over 12 cents per hour to run the pump.

Buy a NEMA 15-R recaptacle at an electrical supply house.

From the specs that you are showing 800 watts @ 230 volts will pull under 3.5 amps. I would install a 20 amp 220 volt circuit with #12 wire. Just double check if the tub requires a 3 wire ckt (2 hots & ground) or a 4 wire ckt. ( 2 hots, neutral & ground) Make sure the ckt. is GFCI protected!
