Is there an easy way to reduce the incident energy on a Service Entrance Swbd.

One of the easiest ways to reduce Incident energy of down stream Distribution on a Service Entrance Swbd, is to separate the Main Disconnect from the rest of the lineup. 

 

If the Main has bottom incoming and top outgoing lugs, you can provide a Top Hat above the Main Section.  On the Distribution Section, you can provide incoming top Lugs with a Top Hat above the incoming Lug Section, then conduit across to connect the two lineups.  I would use some type of fire barrier sealant to make sure the arch can not propagate between the two sections.

 

Even if you separate the two lineups by a foot, the Distribution is no longer dangerous, and if you employ a Maintenance Switch on the Main, you could reduce the Incident energy considerably.
