R-3 Expansion/slip riser set for maximum expansion, over two inches will result in turndown.
Duct
D1 Developer has copy of the pedestal each lot is designed to be fed from, which is where the stub out is installed. Going to the incorrect pedestal will result in a turndown.

D3 Customers using 2 ½ duct must supply a 3” to 2 ½ reducing coupling.
D4 No more than one 90-degree bend will be allowed in a service, if it doesn’t pull, will be turned down.
D5 If duct is not completed to the pedestal/transformer, please do not sod the area until OPPD has completed excavation.
D6 If OPPD needs to complete duct into pedestal/transformer, please do not grade out utility locate marks.
D7 If duct is not connected to a stub out or all the way into the OPPD equipment- contact New Services. This will get the appropriate crew needed to speed up service.
D8 In winter/frost conditions please do not leave the end of the duct pit open to fill with water and freeze, backfill and mark the end.
D9 Cap the end of the duct if not connecting to OPPD stubout.
D10 Bring duct straight to the pedestal, to eliminate as many bends as possible.
