Shipbuilding  Clydebank

The River Clyde has been a centre for shipbuilding for hundreds of years, with boats being built in the area possibly as early as the 15th century.

However, it was during the 19th century, in places such as Bowling Harbour, Denny's Shipyard in Dumbarton, John Brown's Shipyard at Clydebank and Govan Graving Docks, that shipbuilding became a real source of commerce for Glasgow.

The advent of the The steam engine marked massive opportunities for Glasgow to expand its heavy industry.Between 1844 and 1963, Denny's shipyard alone built over 1500 ships. The Denny family was involved in building the first steamship that crossed the Channel (1814), the first turbine steamer (1901), and the first diesel-electric paddle (1934), to name a few. Also well-known from Dumbarton was the fast clipper Cutty Sark, currently a visitor attraction in London.

For many, though, the heart of the shipping industry in Glasgow lay in Govan and the Fairfield Shipyards. At Fairfield, Robert Napier, known as 'the father of shipbuilding on the Clyde', trained many of those who went on to establish leading shipyards,including John Brown's Shipyard in Clydebank. These shipyards grew towards the end of the nineteenth century to become the some of the leading suppliers of the Royal Navy, as well as building liners and steamers, and the tradition continues today with BAe Systems yards at Govan and Scotstoun.

A shipbuiding landmark on the Clyde is the Finnieston Crane at Yokhill. Completed in 1931, it was primarily used to load large steam ocomatives for exportation. In addition, it was used to fit large ships' engines. This impressive machine is still in working order.

After World War Two the shipping industry went into decline and by the 1960's, Fairfield had collapsed.

Recently, however, regeneration of the Clyde Waterfront has attracted new industry to the area, including financial services, digital media and tourism. However, the long tradition of Shipbuilding in the area continues.

ELECTRICAL CONSUMER UNIT REPLACEMENT

Consumer Unit guide to the 17th edition Wiring Regulations 

For Glasgow and Renfrewshire

For well over one hundred years the Wiring Regulations IN scotland and in Glasgow where we are based, have provided the rules which must be followed to make sure that electrical installations are safe. The introduction of the 17th Edition of the Wiring Regulations on the 1st January 2008 has major implications for all Electrical Contractors Glasgow, Designers and Consultants. Installations designed from 1st July 2008 must comply with this new set of Regulations. Several new Regulations will have an impact upon circuit design and consumer unit layout. This guide below will help you understand the new Wiring Regulations and current Building Regulations, providing the necessary facts to construct compliant installations including Consumer Units. Since 2005 the Building regulations for England and Wales has made direct reference to Electrical Installations, increasing the influence on how Electrical Equipment is installed in buildings.

Building Regulations

Part P of the building regulations relates to the electrical safety in dwellings. The approved document prescribes that consumer units should be located so that they are easily reachable where this is necessary to comply with Part M of the building Regulations.

Part M requires that reasonable provision be made for people to gain access to a building and use its facilities. The approved document prescribes that switches, socket outlets and “other equipment” needs to be at appropriate heights, these are defined as between 0.45m and 1.2m from finished floor level.

Other equipment may be taken to include the consumer unit, as it contains devices such as MCB’s and RCD’s that may need operation or resetting by the user of the dwelling. The consumer unit should therefore be accessible, with the devices mounted at a height no greater the 1.2m above the floor. In addition the consumer unit should not be in a location that would make it difficult to access such as an under stairs cupboard. Neither should it be placed in a position where is likely to be damaged by impact. Therefore depending on the layout of the dwelling a flush consumer unit may be considered.

Consumer Units should be easily reachable and be mounted with the switches at a height of between 0.45m & 1.2m above floor level

Scotland Requirements of 17th Edition Wiring Regulations BS 7671:2008

Electricians in Glasgow

This section aims to explain some of the new Regulations contained within the 17th Edition Wiring Regulations, regarding the consumer unit and final circuits. Firstly however, to fully understand what is required, we need to consider some definitions from Part 2 of the Regulations.

• Ordinary Person – Someone who is neither skilled or instructed
  e.g. General public / Home owner
• Skilled Person – A person with technical knowledge or experience to enable him/her to avoid dangers which electricity may create
  e.g. Qualified Electrician
• Instructed Person – A person who has been adequately advised or supervised to enable him/her to avoid dangers which electricity may create
  e.g. Facilities Manager

Typically commercial installations will be under the control of a Skilled or Instructed Person. However domestic and some commercial installations will not. This is particularly important, as certain Regulations only apply to installations not under the supervision of a Skilled or Instructed Person. A significant change is the introduction of Regulations requiring additional protection by RCDs. There are 3 points of consideration,

1. Socket Outlets
2. Cables buried in walls
3. Locations containing a bath or shower

together with some other considerations, like the Division of Installation and about the Fire Detection and Fire Alarm Systems for buildings.

Certain Regulations only apply to installations not under the supervision of a Skilled or Instructed Person i.e. Ordinary persons.

The Regulations have introduced new requirements regarding socket outlets, particularly where used by ordinary persons e.g. Home owners.

Sockets Outlets

The definitions for persons are important to consider when we look at the requirements for protection of circuits supplying socket outlets.  Regulation 411.3.3 requires that an RCD of not exceeding 30mA be provided for:

1. Socket outlets up to 20A that for general use by “ordinary persons”.
2. Mobile equipment up to 32A that is for use outdoors.
   Exceptions to 411.3.3 are permitted where:
3. Use of socket outlets is under the supervision of someone “skilled” or “instructed”.
4. Specifically labelled or otherwise suitably identified socket outlets provided for a particular item of equipment.

This is a change from the 16th Edition that required only socket outlets ‘reasonably expected’ to supply equipment used outside the equipotential zone to have RCD protection e.g. used for an Electric lawn mower. Now under the requirements of the 17th edition it is likely that every socket outlet in a domestic installation will require RCD protection not exceeding 30mA. This may also apply to some commercial installations, like small offices or shops etc where there is no control on the use of those socket outlets. Consideration should also be given to areas where free access to socket outlets is available to the general public e.g. airport lounges.

Socket outlets for general use in a domestic installation require RCD protection not exceeding 30mA

Significant changes affect installations where cables are buried in the wall. This is the normal practice in dwellings.

Cables buried in the wall

  

Here we need to consider Section 522, Selection and erection of wiring systems in relation to external influences. The particular requirements of this section apply to cables which are concealed in a wall or partition at a depth of less than 50mm, or where metal partitions are used. The definitions for persons are once again important for this section. There are 5 options of installing cables in walls. The cables shall:

1. Incorporate an earthed metal covering which is suitable as a protective conductor. Eg SWA cable.
2. Be enclosed in earthed metal conduit, such that is suitable as a protective conductor.
3. Be enclosed in earthed metal trunking, such that is suitable as a protective conductor.
4. Be protected against damage from penetration by nails or screws.
5. Be installed in a safe zone.

This is much the same as the 16th Edition requirements and the usual option is to install cables in a dedicated safe zone. However, where an installation is not under the supervision of someone skilled or instructed, regulation 522.6.7 applies. In this regulation where (5) only from above is used then the cable must have additional protection by the use of a RCD not exceeding 30mA. This would apply where thermoplastic (PVC) wiring systems are used, this is typical in most domestic installations and some commercial installations.

Where buried cables are not mechanically protected additional protection by an RCD not exceeding 30mA must be provided

Although additional regulations relating to bathrooms etc are not new, there are some important changes to consider.

Section 701, Locations containing a bath or shower

Regulation 701.411.3.3 requires that all circuits within this location shall be additionally protected by an RCD not exceeding 30mA. This would mean 230V lighting, the 230V supply to the source for SELV, a shower circuit and bathroom heater for example will all need RCD protection. A standard 13A socket outlet is now permitted in this location provided however the socket outlet is more than 3m from the boundary of zone 1.

The 16th Edition required local supplementary bonding be provided connecting together all exposed and extraneous conductive parts in the zones. This is no longer required in this location provided the following conditions are met:

• All final circuits of the location comply with the automatic disconnection requirements according to regulation 411.3.2.
• All circuits are RCD protected in accordance with 701.411.3.3.
• All extraneous-conductive parts of the location are effectively connected to the protective equipotential bonding according to regulation 411.3.1.2 (Previously termed main equipotential bonding).

All circuits in locations containing a bath or shower shall be protected by an RCD not exceeding 30mA

Qualified electricians paisley Other Considerations

There are additional Regulations and Codes of Practice that need to be considered during the design of an installation. These will affect the choice of consumer unit.

Division of Installation

Section 314 calls for the installation to be so divided to:

1. Avoid hazards and minimize inconvenience in the event of a fault
2. Reduce the possibility of unwanted tripping of the RCD due to excessive protective conductor currents.

To comply with these requirements the circuits of an installation should not be connected to a single RCD, as this could lead to loss of supply to the entire installation in the event of a fault on one circuit, clearly inconvenient for the user of the building.

All circuits of an installation should not be connected to a single RCD

The Wiring Rules & Building regulations are not the only documents that need to be consulted, another important document relates to smoke alarms.

BS 5839-6:2004 Fire detection and Fire alarm systems for buildings

This Code of Practice has particular requirements for dwellings. This document makes reference to the power supply to such systems and mentions RCD’s. The circuit supplying these systems should preferably not be protected by an RCD. This however is going to be difficult to achieve if the circuit supplying these systems is buried in the walls and standard domestic wiring systems are used. Indeed the supply cables would need to be specially protected in earthed metal conduit etc. for RCD protection not to be used.
