Hi all,
2 adjacent terraced houses are being joined into one. The supplier meter cabinet is towards the front of each house and the consumer units are over the rear door in both instances. The heating system is oil and there is no storage electric or heat pumps in either unit, therefore, it is likely both houses are 12kVA supplies with 16mm2 mains tails. The houses were built in 2002. The final house would have only 1 no. cooker with oil heating and so a 12kVa supply should suffice for the final two units combined,

It is proposed that 1 of the supplier meters would be disconnected and the associated consumer unit would be connected with a new 16 mm2 SWA to the other consumer unit. This would serve to minimize the amount of rewiring required,

Question:
1. does the utility (NIE/ESB) have particular requirements for supplies to previously separated houses?
2. Any obvious oversights in the above proposal?

Thank you,

Hello. It look like you are not in the UK but in a separated part of Europe where all sorts of different rules and regualtions may apply.
Don't you have an electricians' forum in your country?
You might try messaging @Risteard
He lives in the UK but knows a little about your part of the World.

I presume that this job is in the 26-Counties given your location of Tralee in Co. Kerry.

Note that this comes within the remit of Restricted Electrical Works, which can only legally be carried out by a Registered Electrical Contractor (REC) - i.e. a member of RECI (also known under the brand of Safe Electric).

The DSO (ESB) do indeed have many rules as evidenced by the National Code of Practice for Customer Interface (4th Edition). As stated, there is also the law regarding Restricted Electrical Works.

All works must comply with the ETCI National Rules for Electrical Installations (4th Edition) ET101:2008.

You should get a REC on board to design this installation for you and proceed from there.
