For assistance in completing the NSF19
Core MPAN (Meter Point Administration Number): - This should have been provided to you by the Distribution Network
Operator. It is unique to the installed metering system connection. If you do not know your MPAN, please refer to the Distribution
Site access: – This should be the contact name and number of the person who will meet and provide access to the metering
agent. The agent will require either the customer, or their electrical contractor, to be at site when they fit the meter.
Distribution Network Operator: – This is the Company installing the service. They will provide you with a quotation for a new
supply. This must be accepted and paid, often accompanied with engineering drawings, a copy of which will need to be passed on
to your electrical contractor. Where it is a CT connection, you will be required to sign a connection agreement.
Electrical contractor: - A wiring certificate is required to confirm that your electrical contractor has completed and tested the
electrical equipment and internal wiring, to a point that it is safe to connect
Agent appointment: - Where it is a CT connection you have the option to appoint a Data Collector/Aggregator and/or Meter
Operator. Please specify the agent and ensure a signed contract is in place with the said agent, prior to the requested supply start
date. For Whole Current connections, SSE will appoint agents, unless you specify otherwise.
Meter type & capability: - There are 2 types of metering – Whole Current (WC) used for supplies up to 69 kVA (3 phase 100amp /
phase) and Current Transformer (CT) for supplies 69 kVA or over. If you are unable to provide this information, please refer to the
Distribution Network Operator. Whole current metering cannot be installed on CT connections, and vice-versa.
CT connections: - You are required to confirm: (a) the cut-out panel is in place (b) the CTs are installed and wired to the CT
chamber test block (c) the customer’s cables “tails” from the main switch to the CT chamber (including “Lugs” crimped onto the
end of each of the tails) are available for connection (d) the Distribution Network Operator has left the cut-out fuse holders in the
sealed CT cabinet. It is the joint responsibility of the customer’s electrical contractor and the Distribution Network Operator to
agree the equipment and work each party is responsible for providing.
CT ratio: - In order to ensure that the correctly programmed meter is installed, please ensure your Distribution Network Operator
contact provides both you, and the Meter Operator, with full details of the appropriate ratio (e.g.100/5, 500/5). Metering systems
installed with an incorrect CT/ VT ratio could result in incorrect billing to the end customer. (VT- Voltage transformer ratio
requested by MOP on HV accounts).
Authorised supply capacity: - This is measured in Kilo Volt Amps (kVA) and is the capacity requested by your electrical contractor /
consultant, sufficient to cover your maximum supply requirements. This capacity requirement should have been incorporated in
the design of the connection by the Distribution Network Operator and included on the connection agreement between
yourselves and the Distribution Network Operator. If you are unsure of this value, please refer to either your electrical contractor
or the Distribution Network Operator. This value is required to provide you with a supply quote. Please do not confuse this value
with the supply amperage (Amps).
Meter position / location: - Where you know the intended position of the metering system, please provide as much detail as
possible. A picture of the meter position should be sent for more complicated installations.
Service plans: - CT Connections, please choose a monthly service plan, and for Whole Current connections, a Quarterly/Monthly
Supply type: - Three types of Whole Current connections, “single phase”, “three phase” and occasionally “split phase”. If you
don’t know the type of connection installed, please refer to the quotation or the connection agreement issued by the Distribution
Voltage: - Three types of CT voltage levels: Low Voltage (LV) - under 1000 volts, High Voltage (HV) - 1,000 volts and above but less
than 22,000 volts and Extra High Voltage (EHV) - 22,000 volts and above. LV supplies can be substation or network fed. Please
advise only if you know how the LV supply is fed. If you do not know the supply voltage, please refer to the quotation or
connection agreement issued by Distribution Network Operator.
Meter installation and energisation date: - Normally we allow 12 weeks to arrange a new connection, including a minimum of 10
working days to arrange for the Metering System to be installed and energised. If the Meter Operator is unable to install due to
incomplete connection work by either the Distribution Network Operator or Electrical Contractor, they will make an aborted
charge. In both instances this charge would be payable by yourselves. Please be aware that a connection energised without a
supplier registration is electricity theft.
