The two poles on this type of motor are for high and low voltage (series and parallel connection) there is no polarity on a.c.(alternating current) motors. if the motor is reversable (an option on some motors) then ther will be a terminal strip in the electrical connection box with jumpers usualy interchanging wires #5 AND #9

How to reverse a IR 2hp compressor motor from cw to ccw

Either the run or start windings must be wired opposite the existing configuration. Single (split) phase motors for compressors typically don't bring out the taps to allow reversal. Check the name plate as it will likely say non reversible.

Dometic a/c unit was subject to reverse polarity at the power pole, now only 2 coils get cold. service tech says just needs recharged but can't because it's a closed unit with no inlet for freon.

have another tech look at it because he would know would need a tap a line to do pressure readings and add freon --as to reverse polarity that would hurt vehicles or battery operated type equipment as to house hold it would be the the low out put voltage that would damage equipment

Changing the "polarity" of the start winding by swapping the wires over should reverse the direction. Lots of online motor-related generic and manufacturer information is available.

Looking for upc code for circuit breaker thql 100 amp or the e a n code

The General Electric THQL two pole 100 amp double breaker?

http://www.azpartsmaster.com/Products/Circuit-Breaker----GE-THQL-100-Amp-DP__BKRTHQL21100.aspx

It's coded HACR.
Heating, Air Conditioning, and Refrigeration equipment.
Means it can be used with electric motors. Electric motors draw a surge of electricity to start.

The UPC code will be for THAT style of breaker, and THAT manufacturer who made it.
Same with the EAN.
It will be on the breaker.

Let's use the Connecticut General Electric THQL 21100 100amp 2-pole breaker for an example;

http://www.plumbersurplus.com/Prod/Connecticut-Electric-THQL21100-100-Amp-2-Pole-General-Electric-Thick-Series-Plug-In-Circuit-Breaker/159077/Cat/1478

Here you see it's UPC is 094925005165

If you are trying to purchase, or guide someone remote from you, in buying a breaker that will fit their service panel, find out what service panel it is.
The Model Number.

This will tell you, or a representative that sells breakers, what General Electric style of breaker that is needed.
Or state it in a Comment, and I'll look it up.

I have Delco Model 2J2424r1, frame 56R, Series A84, phase 3 electric motor. What is the wiring diagram to run it under 230VAC?

If it has 9 leads and is a 240/480 volt motor the 1and 7 go to line 1. the 2 and 8 leads go to line 2 and the 3 and 9 leads go to line 3. the 4 5 and 6 leads are hooked together with a wire nut. To reverse rotation simply reverse any 2 of the line leads.. Prairie Dog........

I need a replacement toggle switch for a chipper/shredder.The 1/12 hp motor experiences frequent slow downs, depending on what is being chopped. Sometimes it even stops momentarily, I presume causing...

My friend did a pretty good search for similar toggle

1) He found a 'wall-type' 30Amp DPDT at Global
2) He said he couldn't find others ... but the internet changes.
3) This switch could be mounted in a box that screws to side of chipper. Switch will work fine with 125V.
4) Radio shack and the automotive stores carry 5 amp versions of the DPDT, but they burn up like you said

5) Here is wiring schematic for switch schematic
6) Note: Wiring is different than automotive-type DPDT toggles where power connects to center pole and loads connect to outside poles
-Power on global DPDT connects to poles L1 and L2
-L1 switches to A1 & B1 ... while L2 switches to A2 & B2.
-Poles L1=>A1 and L2=>A2 turn on-and-off at same time

7) In a reverse of the schematic shown above, my friend is using the global switch on 30Amp water heater to switch voltages between 120 and 240 so we know switch can handle the amperage. schematic
