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. He had been round to the garage, taken a look at what was needed and realising that he was out of his depth he backed off […]
50w NVC Orlando LED Floodlights
During January, we landed several garden lighting jobs around south London. It’s to be expected I suppose since the middle of winter is largely the ‘closed season’ for gardeners. So they wait until it’s the coldest possible time and then call us in to sort out their lighting! Still, we are well used to working outside and in the cold so it’s all in a day’s work. A client in Dulwich needed passive infrared detectors fitting for their garden floodlights, 50w NVC Orlando LED models. These are stylish and […]
Electric vehicles are not new, in the early 1900’s, Ferdinand Porsche produced the world’s first electrically driven vehicle and also the world’s first hybrid too. But petrol and then diesel powered vehicles caught on and electric vehicles slipped into the background other than the iconic milk float. It was only at the opposite end of the century, with greenhouse gas emissions increasing rapidly, that the electric vehicle has resurfaced as a serious contender in the market.
But what are we, commercial electricians, doing talking about the history of the motor industry?
Simple, as electricians, we have always […]
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.
Dangers of over-stressed switchgear
Switchgear is a background items that is often overlooked in the maintenance of an industrial unit. In our experience, it just stands there against a wall, collecting dirt and dust with never a thought of any deterioration that might be happening inside the casing.
One of our recent jobs was for a major car insurance repairer for the south east – ABL at Redhill who inherited the problems of years of neglect of not just their three-phase electrical switchgear but the rest of the electrics too.
They had moved into a commercial unit in which the […]
With more and more vehicles on the roads, an increase in accidental damage is inevitable. Happily, it is the insurers who pick up the tab in most cases, very often through companies like ABL at Redhill, one of our recent clients.
Since they are a major independent SE insurance car repairer who provide top quality work backed up by an excellent customer service, their workshops are always busy. Any failure of the electrical system would be a costly disaster, with a large number of highly trained, well qualified and skilled tradesmen with their hands in their pockets plus disappointed and […]
Five Furniture was established around 20 years ago and moved to their Forest Hill workshops 4 years back. They design and build bespoke pieces for both domestic and commercial clients and as such, they use a lot of serious woodworking equipment – CNC laser cutters, bench saws and edging machines. These all have high power three phase motors on a 100 amp supply.
We were called in when their MK three phase commando sockets had blown and they had been badly let down by another commercial electrical contractor. Idle machines meant a halt to production and potential delays to delivery.
