Don't Push the Test Button!!

[ptonsparky]

I replaced some older CH AFCI when they failed to trip with the test button. Trip coils were shot. New are Dual function AFCI/GFCI
Standing next my panel & thought maybe it's time to test the new ones. The first one I pressed was impressive. Sparks and loud POP. I'm not pressing another test button. It reset so I at least have OC protection. I think.

That doesn't sound right........

No kidding.

I used to do a lot of business with the CH wholesaler. I'll see if that means anything.

They are Eaton now. Their lines are:
BR
CH
So it's confusing to say CH as we don't know if you mean Cutler-Hammer or CH line.

Sparks and loud POP. I'm not pressing another test button.

Same thing happens to outlet devices if test button is depressed under load.

Failure in the energized position never happens with fuses, and should disqualify these devices from UL 486.

The high current loads are the Smoke Detectors in this case.

This morning
Good news - pressing the Test button does not result in sparks and loud pop.

Bad news - pressing the Test button does nothing.

Well I'll be... Wholesaler said they would swap it out as defective.

Recommended order of operations:

* xFCI manufacture technical support should provide you a documented case number, and may prohibit replacement before certain conditions are ruled out.

* OEM has the right to prevent destroying more devices, or keep last one in place, until durable SPD is approved & installed, per NEC 230.67

Some locations with severe utility excursions burn thru most brands of SPD.

* Regardless if utility excursions exist, AHJ may use OEM support records for a code variance, per 210.12(A) exception with existing fire alarms.

* Such AHJ variance with no evidence of surge events, will also be cause for state level amendments, with lobbying assistance from your local Chamber of Commerce.
