Discuss Caravan on site in the UK Electrical Forum area at ElectriciansForums.net
How true I’m just going write a report & recommendations it’s paperwork to maybe wipe your backside with…it’s a sorry state of affairs out there??There is a prohibition on TN-C-S use on building sites and caravans, so yes that is potentially risky. But having seen the condition of cables and connectors on a few sites recently I think the open PEN fault is probably low down on the likely risks
At least they are using a RCD, thankful for small mercies!
Section 704 construction sites:Builders using caravan for site office on a house renovation… he uses every where just plugs it into a Rcd socket.
My thoughts are special location should apply… you can imagine the abuse to come.
704.411.3.1 applies:As far as I am aware there is no prohibition for the use of TN-C-S on a construction site but the requirements for its use would be very difficult to maintain.
TrueWhilst PME is TN-C-S, TN-C-S is not necessarily PME?
I thought that too but scope for that section does explicitly mention excluding caravans…without concern for their actual use.Section 717 Mobile or Transportable Units could be interpreted as applying (examples of units include workshops, offices etc.)
There are loads of people that use their touring caravan as an extra room or as an office plugged into a TNC-S house supply..

I was also musing that a lot of people plug their caravan in on the drive via a 16a to 3 pin adapter to trickle charge the leisure battery. Does that make their drive a special location?
I don’t think it does.
During lockdown with 4 kids at home my caravan became my office connected in this way too!There are loads of people that use their touring caravan as an extra room or as an office plugged into a TNC-S house supply.

Thanks so no real problemSection 704 construction sites:
"This section does not apply to installations in administrative locations of construction sites (e.g. offices, cloakrooms, meeting rooms, canteens, restaurants, dormitories, toilets), where the general requirements of Parts 1 to 6 apply."
Section 708 caravan/ camping parks does not apply.
Section 717 Mobile or Transportable Units could be interpreted as applying (examples of units include workshops, offices etc.)
If so, then, 717.411.4 would apply:
"TN system- a PME earthing facility shall not be used as the means of earthing for an installation falling within the scope of this section except where:
1. The installation is under the supervision of a skilled or instructed person, competent in such work, and
2. The suitability and effectiveness of the means of earthing has been confirmed before the connection is made."
Section 721 concerns itself with the requirements mainly for inside the caravan, except to say that the connection to the caravan shall be by a BS EN 60309-2 plug.
