Caution:
Use a locknut or similar mechanism to ensure the integrity of stud-connected PCTs.
Caution:
The recommended minimum PCT wire size is 2.5 mm² for countries whose mains supply
is 230 V (e.g. Europe) and 3.3 mm² for countries whose mains supply is 110 V (e.g. North
America). This may be superseded by local or country wiring regulations.
For P60 products, the recommended minimum PCT wire size is 6 mm². See product
documentation for details.
Caution:
The PCT connection must have low-inductance and be as short as possible.
Caution:
All connections to the equipment must have a defined potential. Connections that are
pre-wired, but not used, should be earthed, or connected to a common grouped
potential.
4.7
PRE-ENERGISATION CHECKLIST
Caution:
Check voltage rating/polarity (rating label/equipment documentation).
Caution:
Check CT circuit rating (rating label) and integrity of connections.
Caution:
Check protective fuse or miniature circuit breaker (MCB) rating.
Caution:
Check integrity of the PCT connection.
Caution:
Check voltage and current rating of external wiring, ensuring it is appropriate for the
application.
4.8
PERIPHERAL CIRCUITRY
Warning:
Do not open the secondary circuit of a live CT since the high voltage produced may be
lethal to personnel and could damage insulation. Short the secondary of the line CT
before opening any connections to it.
