Hi Dougie,
don't get me wrong, I am not trying to rubbish the suggestions of having your caravan tested to make sure it is safe, at the end of the day dodgy wiring and damaged fixtures can cause death and destruction, not only to the owner of the van but also to the family that are sleeping in the van 3 metres away.
The problem I do have is the way that this idea is being put out scaremongering the public into believing they HAVE to have it done, when they don't.
Think about your household wiring. You may well live in an house which you bought 25~30 years ago, have you had any tests done on the electric since it was bought? most likely not. There is no need to. Until recently even when selling your house you didn't need any type of inspection or certification. On the other hand if you rent your house from a landlord or council there is a need now for them to have the wiring checked every 12 months or whenever a new tenant moves in.
Houses have a far more complex wiring system with many circuits and a supply of ~100A. In my house I have 36 sockets, cooker point, immersion heater, and fused spurs for alarm, fires and boiler, then 17 lighting fixtures, 3 bathrooms and a kitchen. After that there is a multitude of earth bonding.
Based on that and the fact that I have no need to get it tested again until I sell the house, how can the NCC warrant suggesting that caravanner's need their van, with only a handful of lights and sockets (which also hasn't been built in accordance with the segregation rules) be tested by somebody who no doubt in most cases not even be a qualified electrician, more likely an all round "technician" that has been on a three day course held by other caravan techies!
Any "official" work done on my house needs to be done by a real electrician, that has more than likely served a 4 year apprenticeship, studying at college for the equivalent of at least a full year full time, then having to do refresher courses to keep up with current regulations and statute, then he also has to have the work signed off by a qualified supervisor who again has a list of qualifications as long as his arm!
This afternoon I am going to read The Electricity Safety, Quality and Continuity Regulations 2002(http://www.opsi.gov.uk/si/si2002/20022665.htm#24) to see why it is quoted in the info that Damian was supplied with, as on a quick look through it I cannot see how it relates in any way to a caravan.
@Damian,
who is it that supplied that info?
