Arc Flash Exhaust Duct Inspection
Arc Flash Exhaust Duct Inspection
(OP)
I'm going to need to do an inspection for an Arc Flash exhaust duct for a MCC. I've got the information from the manufacturer (Rockwell) about the duct size, pressure drop, material, etc. However, there's one item that I don't know.
The duct joints must be designed to withstand a static load of 1000 lb. I've checked the SMACNA guides I have access to, and they don't cover loads this high. Is there any standard or guides that defines the joint design with up to 1000 lb load?
Thanks.

I would recommend that you start by contacting the MCC manufacturer and see if you can get the details regarding the cabinet construction.
