The 8 cylinder, overhead valve GM 5.7L engine develops 102
hp at 1800 rpm with a displacement of 350 cu.in. The engine
is controlled by an electronic governor, maintaining frequency
at 60hz +/- .5%. DB rating is 74 dBA at standard 7 meters.
The engine features include electronic ignition, engine
blockheater and a vapor fuel system as standard. A critical
grade muffler is installed to reduce engine noise levels.
Battery rack and cables, and a battery tender (charger) are
also installed in the standard package. A BCI Group 24 650
CCA battery must be purchased separately.

Generator
The generator is a single bearing rotating field generator
mounted to the engine flywheel via dual flex drive discs.
Three phase generators have 12 lead broad range
reconnectable stators; single phase stators are 4 lead. An
external voltage regulator maintains proper voltage output,
accurate to +/- 1.5%. The generator features Class H
insulation with harmonic distortion of less than 5% at full
load.
Telephone interference; The THF (as defined by BS4999
Part 40) is better than 2%. The TIF (as defined by ASA
C50.12) is better than 50.
The engine generator combination has the ability to start
and operate motors up to 23 hp Code G. Mainline circuit
breaker included for generator protection.
