In this episode I go over the response I got back from the Eaton engineers about AFCI, GFCI, and DF (AFGF) breakers. I have to say, I’m impressed with the prompt response and depth of detailed information they provided.
Many of you who follow us on Facebook, and are engaged in the several groups we’re a part of, participated in the roundup for questions to ask the Thank you for all of the input, we got a fairly quick response from them, and they did not short us on the details.
I’d like to extend a huge thank you to Lanson D Relyea – Product Line Manager, and Robert (Bob) E Handick – Master Electrician at Eaton for taking the time to answer these questions with great detail and promptly.
1) Will they come out with a duel function type CL Classified breakers? They have them in AFCI (Eaton cl120caf).
[Eaton]: Eaton may consider releasing a classified version of AFGF if there is enough demand. The testing requirements for classified breakers per UL are very labor intensive and expensive. Eaton has to test the breaker in every family of loadcenter across all manufacturers to verify the breaker and loadcenter will work together as a system.
2) Why do all brands twist the neutral pigtail, and is there any down-side to straighten them or to cut them short?
[Eaton]: The twisted or coiled pigtail is simply to fit the breakers in the packaging in the most efficient way. When installing the breakers the pigtail can be kept coiled to allow the ability to extend it or keep short without the need to custom fit via cutting and re-skinning. There is no harm caused by cutting the pigtail or to extend using a wire nut and extra piece of wire (as allowed by the local AHJ).
3) Is there any new developments being made for motors? They need to have more tolerance built into the AFCI’s for motor circuits… Nusicance tripping on refrigerator, freezer and window A/C units gets old real fast. May be different rated AFCI’S, like the personnel and equipment GFCI’S
[Eaton]: Current generation Eaton AFCI product has been designed to be the least susceptible to brush type universal motors that are inherently noisy due to the nature of their design. Our current product does a really good job at distinguishing the difference between the intended arcing inside the motor verses a dangerous unintended arcing situation. Eaton has a dedicated team of engineers that constantly looks to refine our algorithms to ensure compatibility with new and existing appliances.
4) I’ve noticed a lot of problems with mixed loads. Led and fluorescent on the same circuit. I’ve had a lot of problems with the tripping when led lights are on same circuit as an incandescent light and especially with a ceiling fan. What gives?
[Eaton]: We believe the real issue is the conducted emissions (noise) being generated by the LED’s electronic switching power supply more so than mixed loads. Some LED’s are found to be exceeding the conducted emissions limits set by the FCC. This noise looks very similar to a series arcing condition and if all conditions are met, the breaker may trip. The breaker also need to have a minimum amperage of current flowing through it at the same time it recognizes the noise in order for its arc protection to kick in (varies by manufacturer) which is probably why you see more issues when using other loads along with the LED’s on the same circuit. LED does not draw much current so the noise itself does not trip the breaker until you add more load such as the incandescent bulb as you described.
5) Please ask about the coordination with appliance manufactures. The breaker needs to know the signature of appliances that create arc like noise and know to ignore them. Some manufactures ignore the need to make things that comply or to inform breaker manufactures. We end up with the requirement for arc detecting breakers but manufactures that make things that will cause trips which are not arcs. We need better coordination. How do they address this, and do they even try?
[Eaton]: Eaton designs our AFCI devices expecting that appliance manufactures will to adhere to the FCC regulation for conducted emissions. If there is a new appliance or device on the market that exceeds FCC limits, it may create an issue for interoperability.
NEMA has designated a task force to align the AFCI manufacturers with the appliance manufacturers through AHAM (Association of Home Appliance Manufacturers). This partnership is designed to set common design standards across both manufacturing groups. It also allows for a direct connection between manufacturers if there if there are any interoperability issues between the specific brands.
