Suggested Circuit Protection Specifications And Wire Size - Magnetek Impulse G+ series 4 Instruction Manual

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
devices can be thermal, magnetic, or molded-case breakers (MCCB); or "slow-blow" type fuses such
as "CCMR" or "J."
The following guidelines are only suggested values. Always conform to local electrical codes
and wiring practices.
