Prodigit 3310F Series - Fig 3-7 Hook Terminal y Type Large Size Terminal Connections; Table 3-6 Stranded Copper Wire Ampere Capacity

3310F Series Operation Manual 51
A major consideration in making the input connection is the wire size. The minimum wire size is
required to prevent overheating and to maintain good regulation. It is recommended that the wires
should be large enough to limit the voltage drop to less than 0.5V per lead.

3.4.6 Wire/Cable Guide
The following table provides a guide to the current carrying capability (ampacity) of
Both Metric and AWG sizes. Metric sizes are expressed as a cross sectional areas
(CSA). If in any doubt of a cables ampacity it is recommended that you ask your
Cable supplier.

Ampacity of aluminium wire is approximately 84% of
that listed for copper wire.
When two or more wires are bundled together,
ampacity for each wire must be reduced to the
following percentages:
2 conductors 94%
3 conductors 89%
4 conductors 83%
5 conductors 76%
4. Maximum temperatures:
Ambient = 50° C
Conductor = 105° C
