6-7 New Bridge Street

6-7 New Bridge Street

Burgin Contracting has achieved a 70 percent time saving on an electrical installation for prestigious central London offices by using klik 7 pin.

The installation at 6-7 New Bridge Street in Central London has used klik 7 pin from the distribution boards right through to final luminaires and lighting control. The prefabricated wiring system also provides power to fan coil units throughout the seven-storey building.

Andy Collinge, electrical operations manager for Burgin stated "The system has saved us signifacant time in the first fix because there are fewer hard wired connections to make. This labour saving translates into a cost saving on the job making us more competitive in the tender.

"In addition there will be significant savings when it comes to inspection and testing since the system has been designed and manufactured in a factory controlled environment, so it has been pretested. This in turn means that there should be less fault finding before we hand over the completed job and then reduced snagging afterwards."

Burgin Contracting used 11 of our Invicta 3 TP&N distribution boards; three of these boards are for the landlord’s supplies and 8 for tenants. The dual distribution boards are all MID metered for both lighting and power to meet Part L2 and with MID approval can be used for billing tenants if the landlord chooses to do so.

The multi core home run cables from these boards supply area distribution boards (ADBs) in the ceiling void. These in turn are connected into lighting marshalling boxes (LMBs) via link leads. The luminaires then plug into the marshalling boxes as do the occupancy sensors that provide the lighting control.

The occupancy sensors switch the lighting on in response to presence and then switch the luminaires off after a time out period where there is no further presence detected. The occupancy sensors also contain a photocell so that the luminaires switch off if the available natural light is above a set level.

To ensure that the prefabricated wiring system complied with all of the relevant standards and regulations, we designed the system using our bespoke software package. This produced a fully calculated design, which included drawings, electrical calculations, test information and delivery schedules.

"All of the products were delivered complete with drawings that detail exactly what leads should be used where. All of the cables are labelled, so there was no problem in identifying the cables which are used for individual connections, so human error was minimised." stated Andy Collinge.

As a manufacturer who supplies distribution boards, a lighting installation and control system and wiring accessories, we can provide all of the elements needed for a prefabricated wiring system. This minimises the problems that a contractor might have on site in liaising with several manufacturers, whilst maintaining all of the time saving benefits they would expect from a prefabricated wiring system.

In addition to this, our bespoke klik 7 pin software does all of the necessary calculations, such as impedance, cable sizing and voltage drop, which are required for compliance with BS 7671. This validates the design and protects the contractor in design and build operations.
