Hey All,
Looking for a general consensus on the acceptability of plastic boxes being used without firestops where 3.1.9.4. (NBC2015) specifically says anything other than noncombustible boxes installed as per 3.1.9.4.(2) must be firestopped... I've got some Intertek test reports from their lab in China to say that they'll be okay for up to 2-hours in a wall assembly, but the testing standards are all UL - not ULC and not any of the UL standards noted in 1.3.1.2. - and I've refused to accept thus far unless they can give me a test report showing either noncombustible per CAN/ULC-S114 or acceptable performance in a rated wall assembly per CAN/ULC-S101.
Am I in the right here?
Thanks!
