New GFCI Tripping Problem

An RC snubber would be applied to a device expected to produce transient voltages on a regular and frequent basis, for example on a pwm switching device.

A transient filter is placed on a load to catch things coming down the supply.

Significant overlap in the concept, but likely different design constraints.

They didn't call it a surge protector.

They called it a transient voltage filter. I see nothing wrong with calling it that as that is what it does. Then the description/operation information further confirms this is the intent of the item.
 
No it's not. I was saying that the distributor (Rexel) has the description wrong on their website (link that ramsey posted in post #56) and the discussion here took off with that wrong information until I posted the correct information and a link to the manufacturer's website in post #59. That's all.

ETA: You probably missed ransey's link because he linked "Rexel" to the url and it's tough to see that it's a link.

I think part of my misunderstanding was seeing Rexel and R-K as being the same and some time between posts didn't help but I now see they are not the same thing.
 
Have you tracked back the natural and checked to see if the different gfci circuits are sharing a neutral between different legs? I have had problems with this in the past and seperating the neutrals corrected the tripping.

That would only apply downstream of the GFCI protection. These are not line-loaded.
 
Usually with those installations i run a dedicated outlet for the condensate pump and put a gfci after for service. I saw that you stated it was required by the facility but when i took the time to explain to them that by doing it that way, I'm protecting their critical system from nuisance tripping and still protecting their people effectively, they happily approved the change.

Thanks for clarifying the difference.

Would you agree that pwm switching devices are found in High Efficiency residential laundry appliances, and refrigerators, subject to NRTL / UL testing standards that also work fine with domestic AFCI & GFCI safety devices.
 
I understand what you are saying, I'm talking about it being a condition coming in on the neutral and separating the circuits would possibly allow for easier identification of the source issue by it not tripping all the gfci's ? I've seen so many issues like this coming from shared neutrals and thought it might help.

I’ll venture a guess that almost every building you have been in has had a shared neutral.

The entire electrical service is one big shared neutral. I don't see how 'separating' them at the branch-circuit level would make a difference.

I'm with mjerney.

If the customer dictated GFCI and the receptacles are not mandated by NEC to be GFCI, then they made a mistake in putting critical systems on a GFCI.
