I have a box in my garage that says sylvania on the front and a Challenger name in side the cover of the box. One licensed electrician says it's an FPE box and needs to be changed and another licensed electrician says no it does not have to be changed. Anyone know the correct answer?

I have no experience with Federal Pacific Electric panel boxes, but from the responses I have seen here, they are holding places for a future fire.

I would get that panel out of there.

Okay, first do not reply to a note by using the "comments" box. Please use the "Answer this question" box at the bottom of the frame.

Second, I gave you a correct response. The electrician told you it was an FPE panel, not me.

While I have not had any physical experience with the FPE panelboards, does not mean I have not studied them or that I am unfamiliar with there short comings.

The highest reported failure is that their breakers will not reliably trip when under a overcurrent condition. This causes fires, period!

Can you please attach several photos of this panel so that we know for sure what panel you actually have.

If this is true, then this guy...

One licensed electrician says it's an FPE box and needs to be changed...
Is a liar and a crook, and this guy...

... and another licensed electrician says no it does not have to be changed. ... is correct.

If it does not say FPE on the box, then it is not an FPE.

Sylvania and Challanger merged a few years ago, then both dissappeared.

One electrician may have been confused as Challanger was dealing with replacement parts for FPE for a while several years ago.

For anyone here to be certain what you have , may be best for you to post a photo.
