When inspecting electrical systems, bear in mind the following considerations:

  1. Suitability and compatibility of components;
  2. Strength and durability;
  3. Wire bending and connection space;
  4. Electrical insulation;
  5. Heating effects under normal and potential abnormal conditions;
  6. Potential for arcing; and
  7. Classification by type, size voltage, current capacity and specific use.

 

SERVICE DROP

  1. Clearance from obstructions (trees);
  2. No encroachment on neighboring properties;

Clearances Above Grade

  1. 10’ above walking surface (bottom of drip loop);
  2. 12’ above driveway;
  3. 18’ above a roadway; and
  4. 22.5’ above a pool (surface of water). 10’ measured horizontally from pool wall or diving structure.

 

Other Types of Clearances

  1. 8’ (3m)- above a roof with 4&12 pitch or less;
  2. 3’ (3.7m)- above a roofsteeper than 4&12;
  3. 3’ (1m)- clearance from operable windows, doors, porches, balconies, stairs, or any other locations from which a person could touch the service conductors; and
  4. 12" (30cm)- from communications wires/cables at any point, including the point of attachment to the structure

 

At the Home:

  1. Service conductor condition (fraying)
  2. Drip loop, splice
  3. Service drop point of attachment
    1. Suitability and compatibility of components;
    2. Strength and durability;
    3. Wire bending and connection space;
    4. Electrical insulation;
    5. Heating effects under normal and potential abnormal conditions;
    6. Potential for arcing; and
    7. Classification by type, size voltage, current capacity and specific use.
  4. Masthead condition
    1. Raintight
    2. Phenolic insulator
  5. Service mast
    1. Secure attachment, bracing;
    2. Approved type;
    3. Path to ground; and
    4. No other conductors of any type attached.
  6. Meter
    1. Secure in socket, no damage
    2. Height: to center- 4’ min. 6’ max.
