IMPULSE•G+ Mini Advanced Instruction Manual - March 2014
3-8
Suggested Circuit Protection Specifications and Wire Size
In order to comply with most safety standards, some circuit protective devices should be used
between the incoming three-phase power supply and the IMPULSE•G+ Mini. These devices can be
thermal, magnetic, or molded-case breakers (MCCB); or “slow-blow” type fuses such as “CCMR”
or “J.”
CAUTION:
The following guidelines are only suggested values. Always conform to local electrical
codes and wiring practices.
