To test a Siemens GFCI circuit breaker, make sure the breaker handle is in the "ON" position. Depress the "TEST" button. This will cause the handle to move to an intermediate "tripped" position indicating that the GFCI is functioning properly. Reset your circuit breaker by pushing the handle to the "OFF" position first, then "ON."

How to identify a GFCI breaker?
- Turn the circuit breaker off and make a list of everything that is now without power.
- Record the electrical load requirements of each device connected to the circuit.
- Add up the total connected load to see if the amount exceeds the size of the circuit breaker.
What is a GFCI?
1. That is NOT, I repeat NOT a "GFCI" !! GFCI is a VERY SPECIFIC term for a Class A Ground Fault Circuit Interrupter, intended to protect PEOPLE, not machinery. A real GFCI trips at between 4 and no MORE than 6mA of ground current and under 25ms. The device that you have trips in 2 seconds, which is 8 times SLOWER than a GFCI. It's only valid use is as a GFEP (Ground Fault Equipment Protection) accessory that can be added to circuit breakers. They ARE NOT legal as GFCIs in swimming pool applications. NOT!!! The amount of ground current hey trip on could KILL PEOPLE!!! You CANNOT continue on with it this way regardless of finding a way to avoid the nuisance tripping, this is ILLEGAL!
Why do GFCIs trip?
2. Most GFCIs will trip when feeding a VFD, it's a conundrum that the NEC created when they started requiring GFCIs on all pool machinery, like pumps, that now can have VFDs in them. SOME of the pump mfrs have tested their pumps with SPECIFIC brands of GFCI listed breakers, my suggestion is to contact the pump / drive mfr to get they recommendation. The issue that makes GFCIs trip is that the way VFDs are made and work, they ALL create what's called "common mode noise" on the electrical lines; it's unavoidable, and the GFCIs react to it as if is is a ground fault. SOME have different filtering techniques in their electronics firmware inside that can ignore it, some do not, and it also depends on how much noise it sees. Pentair, one of the biggest VF pump suppliers, recommends Siemens GFCIs only as they claim to have tested them and they work with the noise signature of the Pentair drives. So although the GF device you have is Siemens, it is, again, NOT a GFCI.
What size is a pool pump breaker?
Breaker size is 125a. It feeds a control panel which supplies various pool pumps at a splash pad. Recently there was a VFD installed on one of the pumps. My theory is that the VFD is causing the GFCI to trip due to transient voltage. I want to install ferrite rings on the conductors to help minimize transients.
Can you put ferrite cores on wires?
3. There are anecdotal stories of putting ferrite cores on the wires to get GFCIs to hold (again, REAL GFCIs, not what you have), along with using a shielded isolation transformer ahead of the VFD. I cannot vouch for it personally.
Is GFCI a variable frequency?
GFCI always seems to be finicky with variable frequency drives. Typically the manufacturer of the drive/pump will spec a particular GFCI breaker that will function with their drive. Unfortunately for your customer, that probably means running a separate feeder just for this pump not fed by your existing breaker and panel
Do ferrite beads work?
The ferrite beads only work well to attenuate high frequency common mode noise.
What is a dual function circuit breaker?
The dual-function circuit breaker combines class A 5mA GFCI and combination type AFCI, protecting against both arc faults and ground faults. This, along with the new self-test feature, makes it the first in class in electrical safety for homeowners.
What is a Siemens main breaker?
Siemens main breakers (MBK) are designed to allow for convertibility and invertiblilty of Siemens load centers.
How often should GFCIs be tested?
Underwriters Laboratories (UL) suggests that AFCI/GFCI devices be tested every 30 days after installation to ensure they are properly working.
How to close a modal window?
This is a modal window. This modal can be closed by pressing the Escape key or activating the close button.
How to test a 2 pole breaker?
Test for power on a two pole breaker by touching the red voltmeter lead to one of screws with a black or red wire connected to it. Touch the black lead to the other screw with a black or red wire connected to it. You should read 220 volts or close to it on your voltmeter.
How to tell if a GFI breaker is tripped?
Push the test button on the GFI breaker. The breaker should trip. If the breaker does not trip, then it may be that the breaker has already tripped and just looks like it's on. The position of the switch may only move slightly from the on position towards the off position when tripped.
What is a GFI breaker?
Any electrical work should be done, or at least supervised, by a qualified electrician that is familiar with electrical hazards. Troubleshooting a ground fault circuit interrupt, or GFI, breaker is pretty straightforward. Troubleshooting the circuit itself can be quite time-consuming. The GFI breaker is designed with a test button incorporated ...
Why won't my breaker reset?
If any of the bare ground wires are touching any of the screws on the outlets, the breaker won't reset. Push the ground wire away from the other screws to clear the fault and try resetting the breaker. Warning. Be very careful when you work inside of the electrical panel. Always test for power before working on an electrical device.
How to reset a GFI breaker?
Push the switch on the GFI breaker all of the way toward the off position. It may take some force to get the breaker to reset. Turn the breaker back to the on position. When the breaker has been reset properly you should feel some resistance when pushing the switch back on.
How to reset a breaker that won't reset?
Try resetting the breaker again by pushing the switch all the way to the off position and then turning it back to the on position. If it won't reset and trips when the breaker's switch hits the on position, it could be a bad breaker or a problem in the circuit itself.
Why is the test button considered a ground fault?
It is considered a ground fault because the neutral bus in the main electrical panel is actually connected to the ground bus through the panel's metal casing. Advertisement.
