"Approved" is determined by the AHJ.

The spray foam and some silicone tubes are marked with "safe for conductors". Duct seal has always been used, to tell you the truth, I have never looked at the packaging to see if it says the same.

Is it supposed to say, Where portions of a cable, (comma) raceway, or sleeve-----.

Because it says, Where portions of a cable raceway, or sleeve----.

I ask because a little further into it says, --the raceway or sleeve shall be filled---. But it

doesn't mention the cable. Well, how could you fill a cable,right. Then why mention cable

in the first place? This has always bugged me. Anybody have any insight on this?????
