Caravan hook up

Gino:

Spot on you must be a caravan er. Lol. Appoligies I cannot wait till April 1st to post this. This is what's happening actually. But my initial post was really trying to work out the reg wordings. As I want to make my caravan at home safe. So I was thinking of fitting a hook up box next to my outdoor electricity box where the incomer is and the earth bar for all of home. And knowing that the wire would be inside and no more than 18inches long with no or very little chance of damage plus the benifit that it's also connected to the main earth point where gas /water are all connected. I would have not been asking my apparently DIY questions if I was actually running a swa cable underground and Installing a post at my home. As I know it would have to have an earth rod. The posts from everyone has been really intresting and I have been busy looking into new tech, OK the bs7671 is slower and tech is moving fast. But from what I can see and read the new pen loss systems have been accepted within the rules as they are being rolled out. I have one independant unit that has ct clamps within the unit that monitor pe/l/n and if a pe is missed it cuts off all lines and within the regs. 

It's interesting that, depending on the arrangement of metal pipework around your home, installing an independent earth electrode for the caravan pitch may not achieve an improvement in safety.


However, I can confirm that it doesn't matter how quickly technology moves on in this particular instance. Unless and until the relevant legislation - Electricity Safety, Quality and Continuity Regulations - is revised, BS 7671 (and any provisions or guidance from ENA or DNO's) will never allow the connection of a caravan outlet to the earthing terminal in premises supplied from PME, quite simply because Regulation 9(4) does not permit an electricity distributor to connect a PME earthing terminal to a caravan or boat.


In truth, caravans should not be plugged in at homes with PME earthing arrangements.
