Hi all,
At present i stay in a Residential Park home.
I have raised the matter with with the Site Manager that in my opinion the Connection to the Lodges is not in compliance with BS7671:2018 Section 708. The Electrical supply has been confirmed by the DNO by visual inspection to be PME.
Section 708 clearly states that a Residential Park Lodge under ESQCR Regulations states that a PME earthing facility shall not be used for the means of earthing for this type of installation.
Unfortunately the Site Manager is digging his heels in stating he has spoken with 2 Electrical Contractors who say it is perfectly OK to utilise this means of earthing and the a Contractor who carried out an EICR Report stated in his opinion the System was not PME despite the DNO confirming it was in an email.
I have advised in my opinion each lodge should have its own earth rod installed to earth the individual lodges.
I did contact the helpline at Certsure which is a helpline run by the NICEIC.
They did advise that in their opinion BS7671 :2018 would apply.
They also provided an extract from UK Power Networks Engineering Design Standard EDS 06-0017 CUSTOMER LV INSTALLATION EARTHING DESIGN Section 6.9 Mobile Homes which states.
6.9 Mobile Homes
A PME earthing terminal may be provided to mobile homes if the following criteria are satisfied.
The mobile home is permanently sited
The mobile home is is permanently connected to water and sewerage services
The installation is constructed such that a person in contact with the general mass of earth cannot touch any metalwork connected to the earth terminal
The installation complies with the earthing and bonding requirements of BS7671
If these conditions cannot be satisfied the mobile home shall be treated as a caravan in according with Section 5.6
Refer to BS7671:2018 SECTION 721 for earthen and bonding.
Any comments / clarification would be gratefully received.
