18InfoNew added requirements to Spacings
18.1 

Added additional Exceptions to this existing requirement.
Note: Additions to existing requirements are underlined

The spacings of a RPT shall comply with the requirements of Table 18.1.

Exception No. 1: The spacings between the live parts of a receptacle or switch and the intended mounting surface for the receptacle or switch shall not be less than 3/64 in (1.2 mm).

Exception No. 2: As an alternative to Table 18.1, lesser spacings may be acceptable when determined in accordance with the requirements for Clearance and Creepage Distances, Section 19.

Exception No. 3: The acceptability of the inherent spacings of a component shall be based on the requirements for the component.

Exception No. 4: Circuits that comply with the requirements for Isolated Secondary Circuits need not be evaluated for spacings. The spacing between these circuits and other circuits shall comply with Table 18.1.

Table 18.1 Edited existing table: Minimum spacings
Potential involved in voltsMinimum Spacing, in (mm)
0-5051-125126-250
Between any uninsulated live part and an uninsulated live part of opposite polarity, uninsulated grounded part other than the enclosure, or exposed metal partbThrough air3/641.21/161.63/322.4
Over surface3/641.21/161.63/322.4
Between any uninsulated live part and the walls of a metal enclosurebShortest distance3/641.21/46.41/46.4

a A printed-wiring board intended to be completely encapsulated in a suitable potting compound, epoxy, or be conformally coated shall not have any spacing less than 1/32 in (0.8 mm).

b For the purpose of this requirement, a metal piece or component attached to the enclosure is considered to be a part of the enclosure when deformation of the enclosure reduces the spacing between the metal piece or component and uninsulated live parts.

18.4 All uninsulated live parts connected to different circuits shall be spaced from one another as though they were parts of opposite polarity, in accordance with the requirement in 18.6, and shall be investigated on the basis of the highest voltage involved.
18.5 An electrically energized live screw head or nut on the underside of an insulating base shall be prevented from loosening and shall be insulated or spaced from the mounting surface.
18.6 In multicomponent equipment, the spacings from one component to another, from any component to the enclosure, or to other uninsulated dead metal parts excluding the component mounting surface, are based on the maximum voltage rating of the complete equipment and not on the individual component ratings. The inherent spacings within an individual component are investigated on the basis of the voltage used and controlled by the individual component. Spacings between metal oxide varistors, capacitors, and other components shall comply with the minimum spacing requirements in Table 18.1.
18.7 Spacings at a fuse and fuseholder are to be measured with a fuse in place that has the maximum standard dimensions for the rating, and such spacings are to not be less than those specified in Table 18.1.
19InfoNew section added: Clearance and Creepage Distances – Isolated Secondary Circuits
19.1 As an alternative approach to the spacing requirements specified in Section 18.1, and other than as noted in 19.2, clearances and creepage distances in isolated secondary circuits of RPT’s are able to be evaluated in accordance with the requirements in the Standard for Insulation Coordination Including Clearance and Creepage Distances for Electrical Equipment, UL 840, as described in 19.2.
19.2 

In conducting evaluations in accordance with the requirements in the Standard for Insulation
Coordination Including Clearance and Creepage Distances for Electrical Equipment, UL 840, the following guidelines shall be used:

  1. Unless specified elsewhere in this standard, the pollution degree within an RPT housing,
    based on the presence of contaminants and possibility of condensation or moisture, shall be
    pollution degree 2 - Normal;
  2. Pollution degree 2 exists on a printed wiring board between adjacent conductive material
    which is covered by any coating which provides an uninterrupted covering over at least one
    side and the complete distance up to the other side of conductive material;
  3. Any printed wiring board which complies with the requirements in the Standard for Printed
    Wiring Boards, UL 796, shall be considered to provide a Comparative Tracking Index (CTI) of 100, and if it further complies with the requirements for Direct Support in UL 796 then it
    provides a CTI of 175;
  4. For the purposes of compliance with the requirements for coatings of printed wiring boards used to achieve pollution degree 1 in accordance with UL 840, a coating which complies with the requirements for Conformal Coatings in the Standard for Polymeric Materials - Use in Electrical Equipment Evaluations, UL 746C, complies with the requirements;
  5. Pollution degree 1 is also achievable at a specific printed wiring board location by application of at least a 0.79 mm (1/32 inch) thick layer of silicone rubber or for a group of printed wiring boards through potting, without air bubbles, in epoxy or potting material;
  6. Evaluation of clearances, only, to determine equivalence with current through air spacings
    requirements are able to be conducted in accordance with the requirements for Clearance A
    (Equivalency) of UL 840. An impulse test potential having a value as determined in UL 840 is tobe applied across the same points of the device as would be required for the Dielectric Voltage- Withstand Test, Section 28;
  7. As an alternative approach to the spacing requirements specified in Section 18.1 evaluation of clearances and creepage distances shall be conducted in accordance with the requirements in UL 840 for Clearance B (Controlled Overvoltage), and Creepage Distances;
  8. The System Voltage used in the evaluation of the isolated secondary circuitry is able to be
    interpolated with interpolation continued across the table for the Rated Impulse Withstand
    Voltage Peak and Clearance; and
  9. Determination of the dimensions of clearance and creepage distances shall be conducted in accordance with the requirements for Measurement of Clearance and Creepage Distances of UL 840.
22InfoNew added requirements to Grounding
22.1.11 A conductor utilized for grounding that passes through and/or is connected to a movable joint such that the conductor will be flexed, shall be subjected to the Flexing Endurance Test, Section 44.
22.2.9 A conductor utilized for bonding that passes through and/or is connected to a movable joint such that the conductor will be flexed, shall be subjected to the Flexing Endurance Test, Section 44.
25 New section added: Low Voltage Charging and Isolated Secondary Output Circuits
A charging circuit and/or isolated secondary output circuit provided in a RPT, shall comply with the Standard for Class 2 Power Units, UL 1310 or the Standard for Information Technology Equipment Safety - Part 1: General Requirements, UL 60950-1 for Limited Power Circuits.
35.2.3 New added requirements to the Drop impact test
A pedestal mounted RPT shall be grasped along the column and the column held parallel to the floor at any point considered to produce the most severe result. Additional samples may be required to determine the most severe drop. The 3 ft (0.91 m) drop distance specified in 35.2.1 shall be measured from the center line of the column.
38 New section added: Stability Test
As specified in 6.7 a pedestal mounted RPT shall not overturn when tested in accordance with 38.2 – 38.5.
39 New section added: Tipover Test
A pedestal mounted RPT shall comply with Section 35.1 following the tests specified in 39.2.
44 New section added: Flexing Endurance Test
Three samples of a RPT, as required by paragraph 17.12, 22.1.11 and 22.2.9, shall be mounted as intended (if provided with a mounting means) and the movable part(s) shall be subjected to 6000 cycles of movement from one extreme position to the other extreme position. A cycle is one extreme position to the other extreme position returning to the starting position.
