Electricity will always find the easiest path to earth. Any faults or weaknesses within your electrical installation or portable appliances can go undetected. In the event of another fault developing, this could lead to serious risk of fire, electrocution or death.


For example, a 13-amp ring-main without earth continuity could render all metal parts of appliances plugged into it “LIVE” if one item on the ring developed a fault to earth. Fixed wiring testing will accurately identify faults, their locations and usually the recommended solution.
