I have a 21b20m 20kw electric furnace when weather is cold the 100 amp breaker trips two or three times a day can you help please


If you have a heat pump you usually have 1st & 2nd stage emergency heat . Your 2nd set of elements may be bad. You can test this with a meter by ohming across each element and it should read a ohm value. Then ohm from the element to ground and it should read OL if it does not it is shorted. Also 100 amp breakers for some reason always fail I have changed more 100 a breakers than any other size. You can also get an amp probe and turn your thermostat up and read the amp draw to see if it is close to 100a. Hope this helps

Problem With Eaton 9000x VFD drive. All voltages are good. Cannot get drive to activate motor.


Check the windings of the motor at the VFD output. Start by killing power to the VFD. Next, check for voltage on L1, L2 & L3 and U, V & W line to line & line to ground. If all indicate zero, connect an ohm meter from U to V, then V to W and finally W to U. You should see a very low resistance - single digit ohms. They should all be the same value. If that check so out, test from ground to: U, then to V and finally W. This should indicate a very high resistance - 1 meg ohm or more. Do NOT attempt to use a megger to measure ground to U Vand W while connected to the VFD terminals! Low numbers indicate that the insulation on the windings inside the motor are breaking down, and some current is flowing in the ground wire which is dangerous. If all these checks are ok, the likelihood of the motor being to problem is minimal. You should be able to start / run the motor without damage to it at full line voltage - assuming it can start the load at full speed - and that the load can be safely started at full speed. If no to those questions - you should decouple the motor from the load before proceeding. Next, try running the motor "across the line". Many VFD provide such an option and call this "bypass mode" or sometimes "Manual"

Doing this will cause the motor to appear across the *full line voltage* and the motor will attempt to come up to 100% speed *as fast* as it possibly can. If the motor starts & runs, the issue is related to the VFD itself. You may have a loose control wiring, open input / output fuses, etc.

Review the manual with your options, here.

I need a 125 amp GE load center cover the part number is #NP245768-3


Your best bet would be to contact GE directly - or a nearby GE Wholesale Electric Supply distributor. GE, like all electrical panel manufacturers have made many variations of panels to comply with ever-changing code requirements. If it is very old, you may need to locate a used electrical part supplier - or change the entire panel.

Breaker trips after bout 5 minutes


Breakers trip because of heat.
When heat from wire exceeds breaker rating, it trips.
Something is causing heat on the wire, wire is too small for the amp draw, there is short circuit, or breaker is bad.
Replace breaker and/or test wire.

Put amp-meter on wire and read amp draw through wire.
Amps cause heat. That's why high voltage lines from power station are high-volt-low-amp so there is no heat loss with long distance transmission, until transformer at home converts electricity to lower volts and high working amps with enough power to run electrical devices.
Same is true for AC and DC circuits.
If amp reading on wire exceeds rating on breaker for length of time, then breaker will trip.
The fact that the breaker lets current (amps) to flow for a period of time before tripping is because the breaker is probably rated for slow-acting, or it takes a while for amp draw to heat the wire.

Following image shows amp-meter that clips over wire to get amp reading.

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 a 240V hot tub and when I turn on the Cutler-Hammer GFCB250 GFI Circuit Breaker, 50A, it trips immediately. I spoke with a tech support guy from the hot tub mfr who says that the heater and pump...


It is very possible breaker is bad. If you have another 50 amp breaker in the box try swapping them and see if it still trips. GFIC breakers are finicky and they do go bad. I would make sure that the heater is not shorted out before replacing the breaker. It shows 15 ohms which is not what you would normally see which is 9-12 ohms. The reading of 15 ohms you got is high but if the manufacture says that is acceptable then we must assume it is. You also need to test for a short before eliminating the element as a possible cause. Test it with your ohm meter set to the highest setting. Measure between one element terminal and the sheath of the element. Any reading indicates a short to ground indicating the element is bad. If you find it is good then a defective GFCI is really about all it can be.

I have a yamaha fzr 1998 and after renewing alternator and many other parts it still loses battery power the battery goes flat after only 3 miles please can you advice me my next step


Is your alternator after the output rectifier really connected to the battery?

Check if the case is connected both to the rectifier minus and to battery minus and the resistance between them is lower than 1 Ohm. The same for plus ends.

Air handler circuit breaker


WITHOUT ANYTHING TO LOOK AT I WOULD SAY HE CONNECTED HALF THE LOAD TO ONE OF THE PHASE WIRES AND THE OTHER TO THE OTHER PHASE WIRES , PHASE WIRES MEANING 120/240 SINGLE PHASE , SO IF THAT IS THE CASE TAKE THE WIRES HE HAS BUNDLED TO ONE PHASE OR ONE TERMINAL ON THE BREAKER AND THE OTHER TO THE OTHER TERMINAL OF THE BREAKER IN SOME CASES IT IS NECESSARY TO CONNECT THE WIRES WITH CONNECTOR, APPROVED TYPE AND THEN TO THE BREAKER TERMINAL ,THIS JUMPER SHOULD BE RATED THE RATEDING OF THE BREAKER YOU ARE INSTALLING ,GOOD LUCK
