Main to out building

Sorry to bring up this old chestnut but just seeking clarification as it was in 2005 that it was first raised. I am now retired and my last update was C and G 2008

I have been asked to maintain a small sewage tank system for 6 houses. This consists of air pump and controls and lift pump.The pump controls are situated approx 200 metres from the incoming main and earthing / supply is an armoured  cable with cpc which is connected to a TN C S (PME) at origin.

The only metalwork in the tank is a 25mm pipe from lift pump to outlet and internal blower pipework.

Is it allowed to export the PME system in this case or should it have been a TT system with RCD at origin ?

Many thanks FP

  • Reviewing the existing installation all appears to be in order unless I am advised differently.

    1 Requested EIC from contractor

    2 The houses are all under one management system so my maintenance schedule will advise on frequency of pushing test button on rcbo.

    3 There is no extraneous conductive parts/metalwork so PME extended is fine.

    4 RCBO at circuit origin is extra protection to the PME line and covers commando outlet for pump

    6 No entry to electrical panel without authorisation

    7 PME is first circuit from 11kv transformer and crimped lines.

    8 Log book to be used on all service /maintenance issues.
