Assuming the selected Metal-Oxide Varistor (MOV) has a clamping voltage of 400 volts at 1 kiloampere, to maintain a clamping voltage of 400 volts at 5 kiloamperes, you would need to connect 5 of them in parallel. Each MOV would ideally handle 1 kiloampere, provided they share the current equally. While MOVs generally maintain a relatively constant clamping voltage, it's important to note that the clamping voltage can increase slightly with higher surge currents. Here is the paper that explains a little bit in detail: www.bourns.com/docs/technical-documents/technical-library/varistors/bourns-tips-on-selecting-the-right-mov-surge-suppressor-white-paper.pdf?sfvrsn=cb5e43f6_12

Yes, the breaker can withstand such short pulses. It is designed to withstand typical EDS pulses like the 8/20usec one described below.

Hello - Thanks for reaching out. There is a whole science around what type of capacitor and technology and how you attach it. Here is a resource from our partner Seymour Duncan that will help explain. www.seymourduncan.com/blog/latest-updates/what-tone-capacitors-do-i-need-for-my-guitar

For this particular guitar, that is correct. This may not be the same on other guitars. Please refer to the application Note for recommended wiring. www.bourns.com/docs/ProAudioDocs/bourns_model_pdb183_gtr_pot_switch_appnote.pdf

Please check out our Application Note that covers this topic. www.bourns.com/docs/technical-documents/technical-library/sensors-controls/application-notes/Bourns_Model_PDB183_Gtr_pot_switch_AppNote.pdf

All series GDT / MOV solutions (GMOV, IsoMOV and discrete devices) will exhibit this initial voltage spike. It exists while the GDT is turning on and only lasts a fraction of a microsecond. As such, it contains very little energy. In most applications, there are capacitors used in filters on the AC line that will absorb this small amount of energy and it becomes a non-issue. As with every circuit protection design, each designer must confirm the effectiveness of their design in the lab. Bourns has laboratories across the globe that can assist customers that might have concerns in this area.

Hi Ryan - We'd be pleased to replace the defective product, please contact us for further action. [email protected]

Hey Ryan I have the exact same problem. What pot did you end up replacing it with?

@@AveryGuitar fender makes a push pull dime pot. CTS makes a full size push pull pot. I have had good luck with both.

@@smokepeddler thanks

I use a push pull from Dimarzio. I don’t know brand it actually is. Could be Alpha but so far it works great

As long as the fault current doesn’t significantly exceed the PPTC device’s rated current, the PPTC will trip as intended without any smoking.

Thank you for the feedback. Please contact our customer service department if you have any questions on our GMOV products.

We have a Parametric Search you could try: www.bourns.com/parametric-search?Cat=Fixed%20Resistors%20-%20Chip%20Array and www.bourns.com/parametric-search?Cat=Fixed%20Resistors%20-%20Chip%20Resistor

Or he could be using a left handed pot instead of a right handed one

Being right-handed I would have never even put any thought into thinking that left-handed pots or even a thing. That's pretty cool

Please have a look at this application note for wiring information. www.bourns.com/docs/technical-documents/technical-library/sensors-controls/application-notes/Bourns_Model_PDB183_Gtr_pot_switch_AppNote.pdf

@@bournsvideos this is a super helpful diagram! Do you know how I would set up a different combination? I'm trying to use push/pull pots (2) for master volume and only 1 master tone. I'm a bit stumped on the set up. Thanks!
