NOTE: Typical Electrical Circuit is based upon (1) 125% of the
full amperage load of the machine and (2) typical fixed-trip cir-
cuit breaker sizes as listed in the NEC 2002 Edition. Local
codes may require more stringent protection than what is dis-
played here. Always verify with your electrical service con-
tractor that your circuit protection is adequate and meets all
applicable national and local codes. These numbers are pro-
vided in this manual simply for reference and may change
without notice at any given time.
