I agree, George.  I have allowed dielectric unions but some government
agencies insist on a section of CPVC inside the SCIF within 6 inches of the
wall being penetrated.

Thank You

Sounds like he's asking for a dielectric union? Have run into this in
defense settings where they have anti-listening criteria to meet.

Subject: "SCIF" Wall Penetration

Question I am working on a project where the FPE is asking for a
"electrically isolated joint on the sprinkler feed main just inside the
wall"? Has anyone had to deal with this before...if so what did you use? 4"
Sch. 40 Main.
Thanks,
Mike Brown
