BS IEC 62613-1:2011 pdf – Plugs, socket-outlets and ship couplers for high-voltageshore connection systems(HVSC-Systems) Part 1: General requirements.
8.3 It shall not be possible to make single-pole connections between multi-pole plugs and socket-outlets or ship connectors, or between ship inlets and ship connectors. It shall not be possible to make single-pole connections between single-pole and multi-pole accessories.
Improper connections include single-pole connections and other connections which do not comply with the requirements for protection against electric shock.
Corn pl,ance Is checked by inspection.
8.4 It shall not be possible to engage plugs into ship connectors, as in-line cable connections
(cable couplers) are not allowed by the application.
Compliance is checked by inspection and lest.
9 ProtectIon against electric shock
9.1 Accessories shall be so designed that live parts of socket-outlets and ship connectors, when they are wired as In normal use, and live parts of plugs and ship inlets, when they are in partial or complete engagement with the complementary accessories, are not accessible (IP2X according to IEC 60529).
Pilot contacts may be accessible if used at an extra low voltage.
NOTE The neutral contact and pIlo( contacts ot socket-outlets and ship conneclors are deemed to be live parts Pilot contacts are deemed not to be live parts if used at esira low voltage
In addition, it shall not be possible to make contact between a contact of a plug or ship inlet and a contact of a socket-outlet or ship connector while any contact is accessible.
Corn pliance is checked by inspection and. ii necessary, by a lest on the sample wired as En normal use.
The standard test finger shown in Figure 2 Es applied in every possible position, an electrical Indicator, with a voltage not less than 40 V. being used to show contact with the relevant part.
9.2 Accessories shall be so designed that
— when inserting the three-Phase plug or ship connector
• the Earth contact shall make before the Phase contacts,
• the pilot contact shall make after the Phase contacts.
— when withdrawing the three-Phase plug or ship connector
• the pilot contact shall break before the Phase contacts,
• the Phase contacts shall break before the Earth contact.
10 Provision for Earthing
10.1 Accessories shall be provided with an earthing terminal and contact.
Earthing contacts shall be directly and reliably connected to the earthing terminals.
Compliance is checked by inspection.
NOTE Sifle.pOlC Neutral accessories do not have an Earth contact.
10.2 Accessible metal parts of 3P+E accessories with Earthing contact, which may become live in the event of an insulation fault, shall be reliably connected to the internal Earthing terminal(s) by construction.
NOTE I For the purpose 04 this requirement, screws for flung bases, covers and th. lik. are not deemed to be accessible parts which may become rue in the event of an insulation fault.
If accessible metal parts are screened from live pails by metal parts which are connected to an Earthing terminal or Earth4ng contact, or If they are separated from lye parts by double insulation or reinforced Insulation, they are not, for th, purpose of thu reqUirement, regarded aa likely to become live in the event of an insulation f.ult
Compliance is checked by inspection and by the following test:
A current of 25 A derived from an ac. source having a no-load voltage not exceeding 12 V is passed between the Earihing terminal and each of the accessible metal parts in turn
The voltage drop between the Earthing terminal and the accessible metal part Is measured. and the resistance calculated from the current and this voltage drop.
In no case shalt the resistance exceed 0.05 Ii.
NOTE 2 Care should be taken that the contact resistance between tie tip of lh. measunng probe and the metal part under test does not Influence the test results.
10.3 Earthlng contacts shall be capable of carrying a current not less than the capacity of the Earthing conductor of the cable without overheating.
Compliance is checked by the test of Clause 21.
10.4 Earthing contacts shall be shrouded or guarded by the housing of the accessory so that they are protected against accidental mechanical damage.
Compliance is checked by inspection.
NOTE this requirement precludes tile use of side Earthing contacts.
