Conversion of Single Use to Multiple Use
When a building is converted from single use to multiple use, the customer will often use the supply for a temporary builder’s supply; please note that an RCD (residual current device) will be required, connected to the customer’s earth stake for the temporary builder’s supply: it will provide a TT (earth) supply.
The building (house or industrial unit) is then converted into flats.
We as BNO Southwest Ltd shall design and install the Building Network in accordance with ENA EREC G87 and BS 7671 standards.
Example of a New Build
We as BNO Southwest Ltd installs the building network to ENA EREC G87 and BS 7671 standards. A distribution board and mains isolator will be installed. These pieces of equipment provide a single point of isolation for the building and divides up the main supply and provides isolation for each dwelling. There are a number of manufacturers of distribution boards. Distribution boards may be referred to as:
Ryefield Unit
MDSB
The customer’s supplier installs meters via the chosen meter operator. If the meters are located in each flat, then a point of isolation adjacent to the meter will be needed to allow the meter to be fitted. This will often take the form of a solid withdrawable link called a “Red head”.
