- 100% of circuits tested for Earth Loop Impedance values
- 100% of RCDs tested for time and current tripping rates
- 100% inspection of earthing and bonding
- 100% inspection of distribution boards
- 10% of circuits tested for insulation resistance
- 10% inspection of fittings and accessories
All testing and inspection work was carried out by an approved electrician who also has a current City and Guilds 2391 Test and Inspection Certificate.

John Drury and Co. Ltd Soap Manufacturer, Brighouse, West Yorkshire
J Drury and Co. recently commissioned Northern Electrical Services to carry out an Electrical Installation Condition Report. Before this work could be carried out we received a call from the client asking for help as a transformer within the factory had smoke coming out of it and had to be shut down.
Starting at the transformer we quickly traced the fault back to a poorly installed sub main supply cable that a previous contractor had not installed properly. The neutral had overheated and burnt its insulation away and come into contact with earth at the main incomer. The neutral had never been bolted in correctly and was a fault waiting to happen. The factory had to be closed and staff sent home.
Northern Electrical Services sourced a replacement 120mm 4 core steel wire armoured cable and a new 200amp isolator the same day and had it delivered the following morning. Labour resources were redeployed to ensure enough manpower was available to install such a large cable. Less than 24 hours after the problem was first discovered the new cable was installed and connected, restoring power supplies to a large section of the factory which had been shut down thus allowing some production to begin again and minimising disruption to the client.
New Workshop Lighting President Engineering Group, Sheffield
President Engineering had a workshop lit by 13 year old, 6 foot twin T8 fluorescent lights. Their issues were that access was awkward in some areas which meant that the difficult to reach fittings did not get maintained, leaving those areas with very little light. In addition, their light levels were an average of 150 lux that would have been fine in a warehouse, but was nowhere near enough for a precision engineering company.
Northern Electrical Services (Yorkshire) Ltd's solution was to strip out the old fittings which were sent for recycling. In place of each existing fitting we installed a 13A metal-clad socket. Where the original fittings had an emergency pack built in, a second socket was added that was colour-coded red. The works were carried out overnight so as not to disrupt President Engineering’s staff during their working hours.
New 200W induction fluorescent lowbay fittings were added according to a new design, at a ratio of roughly 1 new fitting to 2.5 old fittings, and plugged into the 13A sockets. This of course leaves plenty of spare sockets ready for additional fittings should it be required. The fact that the new fittings merely plug in means that the site's own maintenance staff can replace and add fittings themselves whenever they wish, with no need to bring in an outside contractor. Twin spot emergency fittings were added wherever a ‘red’ socket was located.
Light levels are now an average of 450 lux, whilst energy consumption has been reduced, resulting in savings of nearly £13,000 per year. The installation will pay for itself in less than 2 years. Once anticipated price rises in electricity costs have been accounted for, savings of £200,000 should be achieved over the next 10 years.
With 80,000 hours of expected lamp life with the new fittings, maintenance has been virtually eliminated. Even with their 6am to 10pm, 6 days a week opening hours, the fittings can be expected to last around 16 years before even a lamp change is required.
