n Notes on wiring (global series)
Notes on connecting wires (conductors)
• Connect wires to the UL breaker according to NEC (National
Electric Code) or CEC (Canadian Electrical Code) Part 1.
• Use 75°C copper wires for wiring. UL-certied or CSA-
certified wires are recommended.
• If a large current (for example, a short-circuit current)
flows, it causes a huge electromagnetic force between wires.
Therefore, be sure to secure the wires sufficiently.
• Re-tighten terminal screws periodically.
Block terminal connection
• Choose from the stranded wires shown in Table.
Wire size: AWG or MCM [mm2] No. of wires stranded
14 to 2 [2.1 to 33.6] 7
1 to 4/0 [42.4 to 107.2] 19
250 to 500 [127 to 250] 37
Values in [ ] are those converted from AWG or MCM sizes to mm2.
* See the instruction manual that comes with the breaker for
more details.
Precautions
• Two wires of different sizes cannot be connected to the
same block terminal.
• Be sure to use stranded wires according to Table "Number
of wires stranded."
• Multi-conductor wires cannot be connected.
• Do not solder wires together.
