Is it ok to run al 2-2-2-4 ser in 2" pvc conduit? I would like to run ser cable to 100 amp panel approx 20' inside from external disc. I will run 2" pvc from meter/disc combo down to LB and stub a 12" piece of pvc inside with bushing on end where ser cable would run through. I don't think this would be a problem but would like other opinions. Thanks.
