Requirements for RCD protection on a 32a Socket supplying Mobile Equipment

Liam Puffitt

I have been presented an EICR with a code 2 referencing Regulation 411.3.3, no 30mA RCD protection for socket outlets under 32amp. The 32a socket has a 100mA Time Delay RCD fitted, as it's being used to supply a local DB within a cabin. My initial thoughts were this was satisfactory and shouldn't have been coded a C2 due to the requirement for discrimination between the RCD's to avoid nuisance tripping, now I am not so sure.

    I agree that the circuit is not obvious and I'd be feeling the widower's collar.

    "State Pathologist Heidi Okkers, who carried out a post-mortem examination on Ms O’Gorman’s body, said she had electrocution-type burns to her chest and left arm as well as full thickness burns to her right index finger and thumb."

    Not quite sure what "electrocution-type burns" look like, but it is not unusual to see redness after using a defibrillator, which presumably, the paramedics would have used.

    Not when you pick it up by the wrong end! However, I agree that the full-thickness burns suggest significant current for a significant amount of time and it implies that she could not let go. Finger and thumb strongly suggests a pinch grip, which is typical when using a modern phone.

    "Consultant forensic engineer Paul Collins who examined the scene at the request of gardaí, told the inquest that the cable was just long enough to allow a phone to be held by someone in the bath with their left hand."

    So why were there no burns on the left hand?

    "At that point, he noticed her mobile phone and a cable in the bath, which he grabbed and threw in a sink." "Mr O'Gorman said he got a small electric shock as he was lifting his wife out of the bath before calling to his eldest daughter to dial the emergency services."

    How could he have had a belt if he had already removed the putative source of the shock?

    Very fishy!
