9 CONDUCTOR LENGTH
To optimise transient performance, attempt to
connect units in the “Preferred” fashion as
depicted on pages 11 and 12. Some units have
double terminals to facilitate this. Take care
not to run parallel “protected” and
“unprotected” wiring.
Where this is not possible due to layout or
conductor sizing, use the “Non-preferred” “T”
connection method as depicted on page 13. With
this connection method, the “T” lead length
should be kept as short as practicable (less than
100mm) and wires should be bundled together.
The “T” conductor should be equal in size to the
main conductor, up to a maximum of 6mm
