Low and High Voltage Switchboard Modifications

To make full use of spare capacity LS can advised customers on how best to provide additional motor starters, fuse switches etc. for equipping spare or semi-equipped cubicles, including, if necessary, re-locating existing drives to obtain the most effective solution.

Spare starters are assembled complete, wired and tested in our factory in order to minimise the installation period. The service is available for equipment from any manufacturer, particularly those no longer is existence, Should process requirements exceed the spare capacity available, then LS can manufacture extension tiers to harmonise with the existing equipment.

Non-standard physical arrangements due to lack of switchroom space can be catered for by the use of bus-ducts or turning chambers.


LS can assist with design and feasibility studies and can advise on equipment modification / condition etc., based on our vast experience.


The training of customers operating staff can be carried out either at LS works or on site. The training is invaluable in ensuring that the equipment is used correctly and hence reduces the cost of downtime and maintenance.


LS retains full records of all equipment supplied, over the last 30 years, this enables modern equivalents to be supplied for obsolete components. If the equipment cannot be repaired, LS design staff will provide expert advise and engineer replacement units to fit in with the existing equipment.
