013990-000000-0000001 Scope
1.1 These requirements cover leakage current measurement devices (LCMD) intended for use in marina applications as described in Article 555 of the National Electrical Code, NFPA 70. This measurement device is to be used to allow for means for personnel to measure 60 Hz leakage current for each boat that is supplied by shore power.
1.2 These requirements do not cover:
a) Ground-fault circuit interrupters which are covered by the Standard for Ground Fault Circuit Interrupters, UL 943.
b) Power outlets which are covered by the Standard for Power Outlets, UL 231.
1.3 These requirements are intended for use only in circuits that are grounded at the service entrance. No intentional re-grounding on the load side of the LCMD.
1.4 LCMDs are for onshore use to be placed in series between the shore power outlet and the boat or vessel as a pass-through device for a convenient means to measure leakage current and supply circuit conditions not intended to be a comprehensive instrument or determination of quality or continuity of the grounding circuit to the boat.
1.5 LCMDs may interrupt and/or disconnect current to the load at a predetermined leakage current threshold. See 8.
1.6 LCMDs shall monitor all of the following supply circuit conditions:
a) Open in supply grounding conductor;
b) Reversed polarity of line conductors;
c) Open neutral (grounded conductor);
d) Reversal of ungrounded and grounding conductors;
e) Live Grounding conductor;
f) The absence of conditions (a) – (e); and
g) A Re-grounding condition.
1.7 LCMD measurement of actual electrical phenomena including specific voltage, current, resistance, or similar values shall additionally comply with the Standard for Electrical Equipment for Measurement, Control, and Laboratory Use; Part 1: General Requirements, UL 61010-1 and Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use – Part 2-030: Particular Requirements for Equipment Having Testing or Measuring Circuits UL 61010-2-030.
1.8 A LCMD that also performs other functions, such as overcurrent protection, ground-fault circuit-interruption, surge suppression, any other similar functions, or any combination thereof, comply with the requirements of the applicable Standard or Standards that cover devices that provide those functions.
