2009 circuit protection

Founded in 1897, Wylex introduced the first ‘consumer unit’ to the electrical industry, this original design was the forerunner to the ‘Standard Range’, which is still in wide use today. From its base at Wythenshawe, through a policy of continuous design improvement, Wylex has developed a comprehensive range of Domestic, Commercial and Industrial circuit protection devices based on quality and close attention to the practical requirements of the contractor including the fundamental requirements of electrical safety embodied in the relevant British and International Standards including IEE Wiring Regulations.

GENERAL CONSTRUCTION Wylex MCBs are of the thermal-magnetic current limiting type. MCBs have an easy to operate handle with a trip-free toggle mechanism – so even when the handle is held in the ‘on’ position the MCB is free to trip. AMBIENT TEMPERATURE CONSIDERATIONS Wylex MCBs are calibrated to meet the requirements of BS EN 60898, 30°C Ref Calibration Temperature. At other temperatures the following rating factors should be used: At 60°C 0.9

At 20°C 1.0

At 0°C 1.1

Adjacent thermal-magnetic MCBs should not be continuously loaded at or approaching their nominal rated currents when mounted in enclosures. It is good engineering practice to apply generous derating factors or make provision for adequate free air between devices. In these situations, and in common with other manufacturers, we recommend a 66% diversity factor is applied to the MCB nominal rated current where it is intended to load the MCBs continuously (in excess of 1 hour). METHOD OF OPERATION 1 Moderate overload conditions Detection of moderate overload conditions is achieved by the use of a thermo-metal element which deflects in response to the current passing through it. The thermo-metal element moves against the trip bar releasing the trip mechanism.

2 Short circuit conditions When the current flowing through the MCB reaches a predetermined level, the solenoid directly pulls in the plunger which forcibly separates the contacts and simultaneously releases the trip mechanism. 3 Establishment of arc between fixed and moving contacts As the moving contact moves away from the fixed contact, an arc is established. The arc runs along the arc runner to the arc chamber where it is split up between the plates and extinguished. The low inertia and consequent high speed of the moving contact has a limiting effect on the flow of fault current. The rapid development of the arc, together with its accelerated extinction in the arc chamber, BS EN 60898-2 gives a typical operating time of 3.5-5 milliseconds for a type B curve MCB. CURRENT LIMITING ACTION The high speed current limiting action ensures that the MCB operates before the full prospective fault current is allowed to develop. Under fault conditions, damage can be sustained to the installation and associated equipment due to the amount of energy that passes before the current is completely interrupted. The total energy let-through depends on the value of current and the time for which it flows, and is denoted by the symbol I2t. The high speed current limiting action of MCBs ensures that the energy let-through and any subsequent damage is minimised. This reduced energy let-through assists greatly with both back-up and discrimination considerations. CURRENT LIMITING EFFECT Fault

BACK-UP PROTECTION

CONSUMER UNIT MCBs

Back-up protection is required only if the prospective short circuit current at the point of installation exceeds the breaking capacity of the MCB. When providing back-up protection consideration must be given to discrimination between the MCB and fuse.

DISCRIMINATION It is desirable that the protective device nearest the fault should operate first. The low energy let through of modern MCBs provides better discrimination with HRC fuse back-up than is given by earlier types of MCBs. 1.13 1.45 120 60 40 20

FAULT CURRENT SENSITIVITY As the equipment is fed from the mains electrical supply, in the event of an earth fault the presence of semi-conductors may result in the normal ac waveform being replaced by a non-sinusoidal fault current. In some cases the waveform may be rectified or chopped. These waveforms are said to contain a pulsating dc component which can either partially desensitise or totally disable a standard Type AC RCD. International standards IEC 61008 (RCCBs) and IEC 61009 (RCBOs) divide RCDs into two performance classes: Type AC RCDs for which tripping is ensured for residual sinusoidal alternating currents, whether suddenly applied or slowly arising.

To ensure the correct level of protection, check for the following symbols: TYPE AC normal ac sensitivity

TYPE A pulsating dc sensitivity

Type A RCDs for which tripping is ensured for residual sinusoidal alternating currents and residual pulsating direct currents, whether suddenly applied or slowly arising.

Wylex RCDs are available as both Type AC and Type A devices.

OPERATION

RESIDUAL TRIPPING CURRENTS

The RCD employs the current balance principle which involves the supply conductors to the load (phase and neutral) being wound onto a common transformer core to form the primary windings. Under healthy circuit conditions, the current in the phase conductor is equal to the current in the neutral, and the vector sum of the current is zero. In the event of an earth fault, an amount of current will flow to earth, creating an out of balance situation in the transformer assembly. This out of balance is detected by the secondary winding of the transformer and at a pre-determined level of out of balance will activate the trip mechanism. Single phase and neutral or three phase and neutral units (suitable for 3 or 4 wire systems) are available, the latter being suitable for balanced or unbalanced 3 phase loads. The RCD trip mechanism will operate at a residual current of between 50–100% of its rating tripping current (sensitivity).

10mA Used in special applications where additional protection against contact is essential due to the nature of the installation. 30mA Tripping current designated by the IEE Wiring Regulations to provide additional protection. 100mA Suitable for use where protection is provided to guard against firehazard, etc, rather than to provide additional protection to personnel, and where the earthing requirements need supplementing by RCD protection. 100mA time delay Suitable for use when total RCD protection is required to supplement the system earthing and where local 30mA RCDs are used to give additional protection. The time delay RCD will discriminate with the 30mA RCD.

TRANSIENT EARTH LEAKAGE CURRENTS

If using RCDs in series, discrimination can only be achieved by using Type S devices in series with Types A or AC. See chart below.

All Wylex residual current devices incorporate a high level of immunity to tripping when subjected to transient earth leakage currents. Such transients can occur when there is a significant level of capacitance to earth as can result from cable capacitance (particularly MICC) or RF filter networks. Wylex RCDs are therefore less susceptible to nuisance tripping due to transient earth leakage currents.

300mA For use in large installations where plant and equipment protection are the main considerations and high levels of earth leakage are experienced.

Note: Each circuit may have more than one reason for additional protection by 30mA RCD eg: firstly because of the equipment ie: a socket outlet and secondly because of the cable installation method. Additional protection is provided as additional protection. It does not obviate the need for circuit protection by circuit breakers or fuses. * Regulation 411.3.3 socket outlets with a rated current not exceeding 20A that are for general use by ordinary persons (exemption may be permitted). ** Regulation 701.411.3.3 Additional protection shall be provided for all circuits of the location by use of one or more 30mA RCD. *** Regulations 522.6.6 522.6.7 522.6.8 cables concealed in a wall or partition at less than 50mm depth and without earthed mechanical protection e.g. conduit. **** Regulation 314.1 Every installation shall be divided into circuits as necessary to avoid danger and inconvenience in the event of a fault, take account of danger that may arise from the failure of a single circuit such as a lighting circuit, reduce the possibility of unwanted tripping of RCDs etc. **** Regulation 314.2 Separate circuits to be provided for parts of the installation that need to be separately controlled in such a way that those circuits are not affected by the failure of other circuits. ***** Regulation 560.7.1 Chapter 56 circuits for safety services shall be independent of other circuits. In addition Chapter 51 requires designers/installers to take account of all relevant British Standards and manufacturers instructions. For example BS5839 Part 6 is the British Standard for fire detection and alarm systems in dwellings. It states that power supplies to Grade D smoke alarms should be an independent circuit at the consumer unit, or a separately electrically protected local lighting circuit. British Standards and IEE regulations are subject to change and amendments. This guide to Wylex conssumer units is not a substitute for the regulations which should always be used for all types of ellectrical installation design and installation work.

The WYLEX PSB miniature circuit breakers are rated at 10kA and are of the fault limiting type.

When a short circuit occurs, the current operates a solenoid which trips the mechanism and forces the moving contact away from the fixed contact. The arc generated is forced into an arcing chamber which incorporates splitter plates, to divide and cool it, reducing the total operating time to less than 5ms, This high speed operation substantially reduces the ‘let through’ energy (I2 t) keeping additional damage at the point of the fault to a minimum. Additionally this allows discrimination with HRC fuses at high fault levels.
