The developer/contractor will furnish and install all conduits for the project as shown on drawing supplied by the Engineer.
All conduit shall be gray schedule 40 electrical grade PVC with galvanized steel sweeping 90-degree elbows.
Where primary conduit extends above ground level at pole locations, the developer shall use galvanized rigid steel conduit. One 10 foot section shall be attached to the galvanized elbow underground and 2 additional 10 foot sections shall be supplied to JWEMC for a total of three 10 foot sections per conduit. A grounding bushing shall be supplied for each conduit.
Where lighting conduit extends above ground level at pole locations, the developer shall attach on 10 foot section of gray schedule 40 electrical grade PVC to the elbow underground and two additional 10 foot sections shall be supplied to JWEMC for a total of three 10 foot sections per conduit.
Conduit sizes shall be as follows unless otherwise specified by the JWEMC Engineer:
Single phase primary 2 ½ inches
2 or 3 phase primary 5 inches
Security lights 1 inches
200 amp normal services 2 ½ inches

Secondary (between transformers & pedestals) 3
All conduits shall be continuous from one elbow to the next and glued securely so that the conduit will not pull apart when the conductor is pulled through.
Proper connections between galvanized elbows and PVC conduit shall be installed.
For each continuous section of conduit, a suitable pull rope/string/wire shall be installed from one elbow to the next and be secured at each end. The pull rope/string/wire shall not be glued to the conduit.
Each section of conduit shall be blown clean and dry and capped off. This includes elbows to which conduit will be added at a later date.
Developer/contractor shall be responsible for all conduits until after JWEMC has pulled in all wiring in the project.
