Meter Tampering and Interference with City Property. 11.3.1. It is illegal for any person intentionally and without authority to damage or destroy any meter or metering equipment, or to prevent any meter from properly registering the service supplied by CES, or to divert or otherwise use without authority any service supplied by CES. Violators are subject to a $250.00 fee by CES plus labor, equipment and material costs as applicable. Violators are also subject to prosecution and/or fines to the fullest extent allowed by City Ordinance. Cutting a meter seal or any other unauthorized access, removal, or alteration to CES metering equipment will be considered as meter tampering. 11.3.2. All persons are prohibited from interfering with or disturbing CES electric distribution lines and equipment. Violators are subject to penalties and/or prosecution to the fullest extent allowed by City Ordinance or State Law. Examples of interference or disturbance of CES distribution equipment include but is not limited to: 11.3.2.1.

CES requires a minimum clearance of 14 feet in all directions between CES overhead lines and any new sign or billboard. This requirement applies to the system neutral and to all lines over 750V to ground. 12.1.2. For overhead lines less than 750V to ground, CES requires a minimum clearance of 16.5 feet over roads, alleys, driveways, and any other area subject to truck traffic. For areas not subject to truck traffic, CES typically requires a minimum clearance of 12.5 feet above ground. 12.2. Pad Mounted Transformers, Switches, and Termination Cabinets. 12.2.1. Distance from Eave or Overhang of Building. The State Fire Marshal of Georgia requires that any pad-mounted transformer be installed with at least 10’ between the edge of the transformer pad and building, building overhangs, canopies, exterior walls, balconies, exterior stairs and/or walkways connected to the building. Because some transformers overhang the edge of the pad, transformer pads will typically be installed at least 12’ from the building to ensure adequate clearances. 12.2.2. Distance from Entrance or Exit of Building. The State Fire Marshal of Georgia requires that any pad-mounted transformer be installed with at least 14’ between the edge of the transformer pad and any door on the building. Because some transformers overhang the edge of the pad, transformer pads will typically be installed at least 16’ from any door on the building to ensure adequate clearances. 12.2.3. Distance from Back of Curb or obstruction. CES requires that any pad-mounted transformer be installed with at clearance of at least 3 feet from the edge of the transformer pad to the back of curb or other obstruction. 12.3.

The height of this dedicated electrical space extends from ground/floor level to a height 6’6” above the metering equipment. 12.3.7. No piping, ducts, or equipment foreign to the electrical installation, such as gas meters, water meters, phone/CATV attachments, etc., shall be located above or below the metering equipment. (This does not prohibit grounding and bonding connections for Phone/CATV). 12.3.8. A clearance of at least six feet shall be provided from machinery or devices having moving parts that are not protected by guards, barriers, or other means to prevent physical contact. 12.3.9. CES strongly discourages the presence of vines, ivy, or any other creeping or climbing vegetation in the working space. Such vegetation can damage the metering equipment and service equipment, pose a safety hazard for CES personnel, and can create a fire hazard. CES reserves the right to trim, cut, or remove any landscaping interfering with the required workspace without notice. 12.4. Trees and Vegetation 12.4.1. Vegetation Planted Near Pad-Mounted Equipment, including Transformers, Switches and Termination Cabinets. CES requires that no trees or shrubs be planted within 10 feet of the front of any pad-mounted equipment or within 4 feet of any other side of a pad- mounted transformer. CES may remove such vegetation without notice. Pad mounted equipment can have more than one “front”. Any side with a door, switch handle, or other compartment component that can be opened or operated by CES personnel is considered a “front” of the equipment. 12.4.2. CES does not permit any trees to be planted within the right-of-way, on its easements, or on City utility easements. Any trees found in these areas may be removed without notification to owner. Bushes, shrubs, or grasses may be planted in these areas at the owner’s risk. CES will not repair or replace landscaping in these areas or areas dedicated to utility use. 12.4.3. In areas outside of right-of-way and easements, CES recommends that only low-growth and slow-growth trees be located within 15 feet of an overhead line or within 7.5 feet of an underground line. In no case should trees be planted directly under an overhead power line or directly over an underground power line. ---PAGE BREAK--- CES Contractor’s Manual Revision Date: May 1, 2025 PAGE 25 DISCLAIMER: The information contained in this manual may be changed at anytime.

Required clearances to CES lines and equipment may be subject to NEC, NESC, or other relevant codes or standards. Clearances may also be adjusted due to Electrical Transmission line clearance requirements, railroad or GDOT permit requirements or other similar restrictions. 13. Customer Utilization Equipment. 13.1. Requirement to Balance Load 13.1.1. The customer must balance the load connected across each phase of the service or service bus as nearly as practical. 13.2. Requirements for Motors. 13.2.1. All installed motors should have devices to protect the motor and motor circuit from overload and short circuit. In addition, three phase motors should be protected from single-phase operation. Installation of motor protective devices is the responsibility of the customer. 13.2.2. Single-phase, 115 V motors having a locked-rotor current less than 40 amps, and single- phase 230 V motors having a locked-rotor current less than 100 amps, may normally be started at line voltage. 13.2.3. Single-phase motors having locked-rotor currents exceeding these limits may require special service consideration, and CES engineering must be consulted before purchasing or connecting such motors. 13.2.4. Because allowable locked-rotor currents vary at different locations, a CES engineer shall be consulted before connecting poly-phase motors to CES distribution system. 13.2.5. CES reserves the right to disallow motors to be started without the application of reduced voltage motor starters. A 25 hp motor or smaller can normally be started without aid of a starter unless problems exist. The starting characteristics of motors larger than 25 hp will be verified by CES engineer to determine if reduced voltage motor starters are needed. 13.3. Requirements for X-Ray, Welders, Power Electronic and similar equipment. 13.3.1. The customer should consult with CES prior to purchasing or installing any utilization equipment that has the potential to cause voltage fluctuation, waveform distortion, or other system disturbances. ---PAGE BREAK--- CES Contractor’s Manual Revision Date: May 1, 2025 PAGE 26 DISCLAIMER: The information contained in this manual may be changed at anytime.

Current and Voltage Harmonic Distortion Limits. 13.4.1. Certain non-linear loads can cause harmonic distortion. Current and voltage distortion should be limited to the values specified in IEEE519-2014 (or current version). 13.4.2. Total Demand Distortions (TDD) should be typically limited to 5% - 20% of the total maximum metered annual demand. The exact limit will depend on the available short circuit current at the customer’s location. Contact CES to obtain the TDD limit for a specific location. 13.4.3. Voltage Total Harmonic Distortion (THD) should be limited to 8% for delivery voltages less than 1000V and 5% for delivery voltages between 1000V and 69kV. 13.4.4. Individual component harmonic levels for both voltage and current are required to be less than the stated total limits above. 13.4.5.
