    Making New Connections Quick, Simple and Futureproof

    New utility connections in London can be particularly challenging, with road and pavement closures adding significant costs to poorly planned implementations.

    We help clients best-plan such connections to ensure costs are minimised.

    New Electrical Connections

    Electrical Connections for Garden Squares come with their own set of relatively-unique challenges.

    Specialist conduit must be laid from the street-side connection through to a newly installed Electrical Enclosure, typically made from Glass Reinforced Plastic installed on-top of the concrete slab. The specifications for how the conduit is run, the slab is laid, and the GRP Enclosure is sized/positioned are all explicit, and failure to follow them could lead to installation delays with significant costs being passed on by the Distribution Network Operator.

    We are able to work with clients to ensure service routes are well planned and every preparation made ahead of new Electrical Connections.

     

    Planning for Voltage Drop

    Voltage Drop is a consistent issue, with larger cables needed to cover longer distances within acceptable resistance levels.

    Correctly specifying new connections (single phase vs three phase), and the subsequent cabling, therefore require thorough consideration of planned and potential uses of electricity. This ranges from future battery-powered Gardening Equipment and where it will be charged, to the preferable location of irrigation tanks / pumps (if ever installed).

    All such factors will affect the potential load at different locations within the garden, and as such, the thickness of cable that must be run to compensate for voltage drop.

    Avoiding Failure-Prone Features

    Part of regularly conducting infrastructure works in Gardens is coming across the “What Not To Dos”. We frequently encounter failed electrical installations where circuits trip because joins have been made underground, in unsatisfactory equipment.

    Our solution is to simply avoid underground joins wherever possible. Where cable joins are required (e.g. to branch a circuit), we bring the cables up to an elevated, satisfactorily elevated waterproof enclosure / junction box, mounted on a no-rot surface (e.g. slab) or post (e.g. composite). Where joins can be avoided, we avoid them, even if it means pulling 160m and 250kg of armoured cable through underground conduit inch by inch.

    This approach not only enhances the safety of the installation, but also its longevity, minimising costs in the long run.
