E57:
Services here (NJ) the EC does the install, RGC,Conductors, drop hook, etc.
On BUD, PSE&G supplies/installs line side to meter pan; EC supplies conduit/fittings from bottom of meter pan to depth in trench. (PVC, ta, bush, etc)
Other UG, EC installs conduit & conductors from meter pan to 10' +/- up pole. Now 2-1/2" PVC min. for 200 a.
AS to service sizes, 100 min is still OK
Large comm/ind primary conduit by EC, pull boxes (if req) by EC (PSE&G Spec) primary conductors S&I by PSE&G. Secondary side; all on EC incl. terminations in pad mount.
