(3) Insulation resistance shall be measured with a megger generating not less than 500 or more than 1,000 volts. A multimeter is not acceptable because it applies only a few volts which will permit some insulation defects to go undetected. Erratic behavior of the megger during the test indicates an intermittent weakness which must be corrected. Only the lower value indicated shall be considered or recorded.
(4) The Village Engineer's representative shall log the serial number and voltage rating of the megger used by the contractor. He shall then confirm the calibration of the megger by connecting the two leads of the megger together so that the resistance to be measured by the megger when it is turned at full speed is zero. Unless this is true, the megger will give false reading under all other circumstances as well.
(5) Each circuit shall be permanently tagged for identification and then tested at the control centers. The full voltage of the megger shall be applied between ground and each insulated wire in each circuit. The ground shall consist of a driven, copper-clad rod 8' x 5/8" or larger connected by #8 wire to the ground terminal in the control cabinet. Circuits shall be isolated from each other by opening the circuit breakers.
(6) The minimum, acceptable resistance to ground shown by the megger shall be 250,000 ohms. The tests shall be conducted as follows:
(a) Test at each pole location from handhole to the last light in a string of lights. Locate any faults in underground cable before connecting lamps.
(b) Test each lamp assembly at handhole using the #10 downwire in each of the lamp poles. Correct any faults.
(c) Test the complete system with all connections made except the fuses will not be installed in the switch box. Test the system from fuse output lug to ground at the switch box.
(d) If a service center, check each circuit at the breaker output in the control center.
(e) All tests shall be conducted in the presence of a representative of the village or the Village Engineer.
(7) With all lamps "on" for a minimum of five minutes, measure the voltage at the fuse output lug in the safety switch box. Then using the same meter, measure the voltage to the last light in the string at the handhole connection in the base of the pole for that lamp. The percent of voltage drop from the supply fuse to the lamp shall not be more than 2%.
(8) A test log shall be used during the test noting all results and identifying all meters used. Test logs will be signed by the contractor's representative and the Village Engineer's witness.
(K) Service and control center.
(1) Service centers, if used, shall be established at such points as are found feasible for the area to be serviced. The final selection of a service and control center shall be approved by the Village Engineer and the Commonwealth Edison Co. At each service center, the service switch and circuit breaker shall be mounted in a weather-proof cabinet made of rust-resistant metal or aluminum and shall be marked "Street Lighting". This cabinet shall be equal to Crouse Hinds #27394 adapter.
(2) The cabinet shall be mounted on an 18 inch diameter concrete base 4'-0" deep cast in place consisting of four vertical rods and #3 rings 12 inches and on center for reinforcing. The top of the base shall be two and one-half inches (+1/2") above finished grade. The base shall include a two inch feeder conduit with standard radius and one and one-half inch service conduit connected directly to the meter socket as required by Commonwealth Edison Co. All feeder and supply conduit shall enter the cabinet from the bottom.
(3) The service center distribution cabinet shall be securely grounded by driving into the ground a 3/4" x 10' copperweld ground rod inside concrete base of a cabinet and connected to control panel ground terminal. On the back of the control center shall be mounted the meter socket for the mounting of the service meter. The control center cabinet shall be provided with a secure locking facility and duplicate keys must be provided for same.
