circuit Breaker : A mechanical device for making and breaking a circuit, b0th

under normal conditions and under abnormal conditions, such as those of an

overload or short circuit being broken automatically.

Circuit Conductor : A current carrying conductor forming part a circuit or final

sub circuit, but excluding the eadh continuity conductor.

Conductor ( Of Core Or Cable ) : The conducting podion, consisting of a

single wire or of a group of wires in contact with each other. For earthed.

concentric wiring, the term may also denote the metal sheath of a cable.

Connpctor : A device intended for connection to a flexible core of flexible

cable, which has protected current carrying contact tubes similar to those of a

socket outlet.

Customer's Installation ; W iring and apparatus situated upon the customer's

prem ises and controlled or installed by him, excluding any switchgear of the

supply undedaking which the customer m ay be permitted to use.

Customer's Terminals : The point in the customer's installation at which the

incoming supply of energy is delivered to that installation.

Core ( Of Cable ) : The conductor with its insulation but not including any

outer covering for mechanical or other protection.

Dam p And Dust Proof : Applied to apparatus and accessories to denote that

the live and other com ponent parts are protected by an enclosure or

enclosures being so protected and / or fitted as to prevent the ready ingress of

dust and / or moisture.

Dam p Situation : A situation in which moisture is either permanently present

or interm ittently present, to such an extent as to be Iikely to impair the

effectiveness of an installation conforming to the requirements for ordinary

situations.

Dead : At earth potential and disconnected from any live system .

intrinsicallv Safe :

1. Applied to a circuit, denotes that any electrical sjarking that may occur,

in normal working under the conditions speclfied by the cedifying

authority and with the jrescribed components is incapable of causing

an ignition of the prescrlbed flam mable gas or vapour.

2. Applied to apparatus, denotes that it is so constructed that when

installed and operated under the conditions specified by the cedifying

authority, any electrical sparking that may occur in normal worklng,

either in the apparatus or in the circuit associated therewith, is

incapable of causing ignition of the prescribed flammable gas or

vapour.

Isolator : A mechanical device capable of opening or closing a circuit

under conditions of no Ioad or negligible current. Not To Be Used For T#e

M ain Disconnectinn Device Of A Main Switchboard. The Isolator shall

be complying with BS EN 60947 Pad 03 : 1999 ( Switches, Disconnectors,

Switch - Disconnectors And Fuse - Combination Units ).

Live : ln reîation to a conductor, means that, under working conditions :

1. A difference of voltage exists between the conductor and eadh or ;

2. It is connected to the m iddle wire,common return wire or neutral

wire of a supply system in which that wire is not permanently and

solidly eadhed.

Neutral Conductor : The neutral conductor of a 3 Phase 4 W ire system ,

the conductor of a Single Phase of D.C. installation which is eadhed by the

supply undedaking ( or otherwise at the source of the supply ) or the middle

wire or common return conductor of a 3 W ire D.C, or 3 W ire Single Phase

system.

Non - Combustible : A non - combustible material is one which is not

capable of undergoing combustion and satisfies the performance

requirements specified in the non - combustibility test of BS 476

( Fire Tests On-Building Materials And Structures ), BS 476 Pad 04 : 1970

( 1984 ) ( Non - Combustibility Test For Materials ).
