We had a recent job in Lewisham at a garage who had bought some new ramps and a rolling road for doing their MoT brake tests. They had been fixed to the floor and needed wiring in. They had contacted an electrician in Lewisham who had not really been up to the job – he was a one-man-band rather than a commercial electrician and had little experience with working on three-phase supplies.

Professional installation of switchgear in London

When switchgear is installed, it needs regular checking and maintenance to ensure that it remains safe and working properly. We have encountered many situations where switchgear has been fitted in an industrial unit years ago and hardly looked at since. Changes to the network that feeds it such as an increase in the infeed capacity or changes to the systems fed from the switchgear can all contribute to over-stressing. Switchgear is over-stressed when the potential fault energy could exceed the fault rating.
