• yAt least one capacitor bank will be required within the service area of each crossing . The capacitor bank must be located within 100 feet of a switch cabinet .
• yFPL prefers 10 ' x10 ' easements for single phase transformers . Open Delta Bank Transformers require a 13 ' x10 ' easement . Three-phase transformers require anywhere from 10 ' x10 ' to 20 ' x20 ' depending on the load . FPL prefers 20 ' x20 ' easements for switch cabinets and capacitor banks . Underground Feeder Splice boxes require a 7 ' x22 ' easement . Underground Handhole easements can vary between 5 ' x5 ' and 5 ' x20 ' depending on the size of the handhole and configuration of the undergrounding wiring . Actual easement dimensions and configurations may vary depending on the specific situation , field conditions , and types of equipment to be installed . Easements must be located adjacent to and accessed from the public right-of-way .
• yElectrical equipment shall be located so it can be accessed easily by a truck .
• yTransformers will be located based on electrical loading requirements . For example , a home with a large electrical service may need a single dedicated transformer . Conversely , homes with smaller electrical services may be able to share a single transformer .

• yTransformers should be located on one side of the street to the extent practical .
• yTransformers shall be the “ low profile ” style to the extent practical . In certain situations , such as three phase services and large services requiring service wire greater than 4 / 0 in size , a “ regular ” style transformer shall be used .
• yElectrical equipment requires three feet of clear area on the sides and rear of the equipment and eight feet in the front of the equipment for access and maintenance . Standard switch cabinets require eight feet of clearance in both the front and rear of the cabinet .
• yExisting handholes connected to existing electrical services to the building / facility may be reused if they are located near the front street . Existing handholes located at the rear of the property will not be allowed to be reused if the service is being converted from the rear to the front of the lot . This is for safety , maintenance , and to prevent unauthorized connections .
• yNew conduit will be installed between the transformer and the facility service entrance or existing handhole , as applicable , to contain the service or secondary service cable .
• yFacility service entrances shall meet current NEC standards for connection to the new underground system .

• yOverhead facility services will be converted to an underground location . This may require replacement of the service entrance if the meter can cannot accommodate new underground conductors . Overhead weather heads will be abandoned in place .
5.4 AT & T
AT & T provides communications service to the Town through a network of copper coaxial cables . Much of the trunk line already exists in an underground location . Distribution of service is accomplished to most homes and businesses through underground to overhead transitions at the overhead radial line locations . AT & T intends to continue service to the Town through a copper coaxial system . They indicated that they are budgeting internally to upgrade to fiber service in the future but they are not prepared to make this conversion in conjunction with the undergrounding program . They have indicated that the upgrade could begin to occur soon after the completion of the initial program phase .
AT & T will perform the communications network design for the program with Kimley-Horn developing the supplemental conduit plans to aid the Town ’ s contractor in installing the conduit for the project . AT & T has communicated the
|
following general guidelines related to the design of the improvements .
• yMain underground trunklines and equipment shall remain in service ( including existing SAIs and CEVs ).
• yThe existing underground trunk line shall be reused . Distribution of service will be converted to underground through connection to the trunk line at existing trunk line manhole locations .
