Hymie, I'm afraid you're wrong. Under the Provision and Use of Work Equipment Regulations in the UK, an employer is strictly liable for any injury caused to an employee by defective equipment, electrical or otherwise. There is no defence. If the item has been properly looked after and the problem relates to a defect, the employer may be able to pass on some or all of the liability to the manufacturer or supplier, but if he hasn't done anything to maintain or even check it for safety, he probably wouldn't have a leg to stand on. It would be a very foolhardy employer indeed who tried to save money on PAT testing and thereby exposed employees to risk - what about the power lead that gets trapped and kinked during an office reorganisation, or a cup of coffee spilt over a fan heater - should an employer ignore these events too, or assume they don't need to check these items?
