Most of the electricians in my area use seu. Although there are some towns inspectors who enforce pvc risers. I have a question also, GRC or PVC Shc80 ??
Mostly SEC residentially. Pipe on commercial. PVC or RMC use splits about 50/50, just depends on the type of job. On the PVC we use sched 40 unless it's between the meter and the earth (for the lateral)then the utility mandates sched 80.
It may be a good idea to check, before using RMC, if your utility supplies the meter pan, that the pan neutral is not bonded to the meter enclosure, is seems the meter pans that some of the utility provides, had bonded neutrals, good for PVC, or service cable.
98% are done in PVC and 2% in SE. Also the SE has to be copper or I will not it. These numbers are strictly for residential services. RMC for commercial & industrial services.
Why would the AHJ require PVC, if SEU meets the code of the NEC? That would of course unless there is a town ordinence or POCO rule then that might be a different story. Here in NJ most guys use SEU.
