Specifications include, but are not limited to: 3.1 Scope of Work. New 200 Amp Electrical Entrance Mid-American Energy has installed a new Secondary Transformer next to the ICN Hut. Electrician needs to Install new cables from Secondary Transformer to the Meter Socket. Distance from Secondary Transformer and Meter Socket location will be about 25 horizonal feet. Cables shall be at or below the minimum depth required by Code. Cables shall be installed in Waterproof Conduit and be plugged on both ends. Continuous, “Non-Jointed” conduit will be preferred. Cables shall be sized to have less Voltage Drop then maximum allowed by NEC Code. List “Estimated Voltage Drop” in Quote. Install new 200-amp Meter Socket into Hut. Install a New 200 Amp Electrical Meter Socket Box on the outside southeast corner where the existing 100 Amp Meter Socket is at. Remove and discard existing meter socket. Remove and discard existing entrance wiring and conduit. Existing 100 Amp Wiring and Conduit will probably not meet Code Specs for new 200-amp entrance service. Install new wiring & conduit (as needed) from meter socket to the hut’s New 200 Amp Disconnect Breaker on the East Wall. Wire from the Disconnect Breaker to the new 200 Amp “A” Panel. Option #3 - New 200 Amp Disconnect Breaker can be placed on the South wall if it allows for more efficient install of other electrical components. All NEC, Local & State Code Space Clearances must be followed for all electrical components. Install New 200 Amp “A” Electric Breaker Panel in Hut Install a New 200 Amp “A” Breaker Panel - Currently the hut only has a 100 Amp Disconnect breaker and a 100 Amp “B” Panel only, there is no “A” Panel existing. Move the Generator Water Jacket Heater and the Generator Battery Charger circuits from the current “B” Panel to the new 200 Amp “A” Panel. (See Circuit Breaker Layout Excel Spreadsheet). Generator Water Jacket Heater Circuit - 20 Amp, Double Pole, 120 VAC. Generator Battery Charger Circuit - 20 Amp, Double Pole, 120 VAC. Remaining electrical circuits will be installed on New 200 Amp “B” Panel. (See Circuit Breaker Layout Excel Spreadsheet). Placement of “A” Panel can be as shown on Option #1 or Option #2 in drawing. Due to size of ATS, New Disconnect Breaker can be moved to the adjacent South wall, (wall with the door). (This is shown as Option #3). “A” Panel will need to be connected to the ATS Switch on a 150 Amp Breaker. Install Automatic Transfer Switch (ATS) Pickup 200 Amp ATS form ICN Warehouse. Coordinate with ICN Facilities Group for pickup time or to coordinate delivery of switch to site. Install ATS per location indicated by either Option #1 or Option #2 drawing. ATS will sit directly on the floor. Anchor securely. Connect ATS to B Panel. Connect ATS to Generator. Connect ATS to Commercial Power from the “A” Panel. Install new 200 Amp “B” Panel Install a New 200 Amp “B” Breaker Panel - (Currently the hut only has a 100 amp “B” Panel.) “B” Panel should have a 150 Amp Main Breaker from the ATS. “B” Panel can be installed per Option #1 or Option #2. Existing Conduits will need to be rerouted to “B” Panel. See Breaker Panel Worksheet for list of circuits. Five Circuits - 20 Amp, Single Pole, 120 VAC. Overhead Lights Exhaust Fan & Intake Louvers Receptacles Group #1 Receptacles Group #2 Receptacles Group #3 One Circuits - 15 Amp, Single Pole, 120 VAC. Outside Security Light One Circuits - 30 Amp, Double Pole, 240 VAC. Two Baseboard Heaters (on same breaker) Five Circuits - 20 Amp, Double Pole, 240 VAC.
